Dieses Online-Buch gibt es nur, weil 1999 zwei Dinge zur gleichen Zeit aufeinander trafen: Mein Interesse für Ninjutsu und mein Interesse für Webdesign.
Als ich in den 90ern zum ersten Mal mit Ninjutsu in Kontakt kam, war Information sehr schwer zu finden. Dōjō gab es nur sehr spärlich im deutschen Raum, keines davon in Reichweite für mich. Bücher gab es kaum, und die wenigen Bücher, die es gab waren sehr schwer zu beschaffen (ich musste im Voraus bezahlen, ohne sie je gesehen zu haben und wochen- oder gar monatelang auf die Lieferung warten). Ich habe damals jede Information, die mir in die Hände fiel gesammelt und mir Notizen gemacht. Diese Notizensammlung wurde das, was heute diese Website ist.

+author: "Stefan Imhoff"
+excerpt: "Breathing involves hitting or pressing on the nerve points of the body. There are several hundred spots on the human body, here are the 69 most important ones."
+translationKey: "atemitePage"

+
+## Pressure and Blow to Nerve Points
+
+_Atemite_ is the name of the pressure, blow or impact on the approximately 250 sensitive areas of the human body. The effects of the blows range from harmless pain that forces the opponent to submit, others (69 critical) are classified as dangerous because they can lead to unconsciousness, paralysis, or death. These points are nerve centers, vital organs, or concentrations of blood vessels.
+
+{% banner "Warning" %}
+
+When training, the points must **never** be hit with full force, but only lightly touched or pressed with increasing pressure to check whether the point has been hit!
+
+{% endbanner %}
+
+A Ninja should always know exactly about the points of the body, on the one hand, to be able to protect himself better and on the other hand to be able to defend himself effectively.
+
+To achieve an effect with _atemi_, the blows must be mastered perfectly and placed extremely precisely (on the smallest possible area). In order not to kill the opponent immediately, you have to calculate the opponent’s constitution and thus determine the hit dosage.
+
+To better protect yourself, it is essential to develop a strong chest and abdominal muscles.
+
+## Explanation of Hit Zones
+
+
+
+The 69 most important hit zones are explained in more detail below. In addition to the number and name of the area, the preferred body weapons and the effect of a hit on them are also mentioned.

+## Ten Thousand Rivers Flow Into the Sea
+
+Fujibayashi’s **Bansenshūkai** is a compilation of the knowledge and views of dozens of Ninja-Ryū, the Iga, and Kōga regions of south-central Japan. Well-known historians consider these writings to be extremely systematic and logical in structure, both in terms of the subject areas covered and in the way in which the individual chapters are divided.
+
+In the summer of 1676, Fujibayashi Yasuyoshi collected the material. Japan was under the rule of the fourth Tokugawa shogun during this period. Fujibayashi was a member of one of the three main Ninja-Ryū in the Iga region. At the end of the _sengoku jidai_, his family, along with the Hattori and the Momochi, had the greatest reputation and influence.

+{% endproductshelf %}
+
+### Yo
+
+The first of ten hand-bound volumes contains an introduction, historical examples, a table of contents, and a question-and-answer section. The guiding philosophy of the Ninja is presented in this book, titled **Yo**, through a discussion of successful warfare. The Ninja is urged to remember that if a leader properly directs and motivates his people, large numbers of enemies can be overwhelmed. However, if the followers think differently than their commanders, then defeats and losses will not be long in coming. A single properly deployed spy or enemy agent can bring down an entire army. Therefore, the Ninja believes that one person can defeat thousands of enemies. The Bansenshūkai consistently emphasizes that Ninjutsu is the most effective method of military strategy.
+
+### Shoshin
+
+The second volume is called **Shoshin**. It’s about honesty, motivation, and the moral willpower that a Ninja needs. Since he also employs skills that others would describe as treachery, lies, theft, or deceit—not to mention the extremely harsh uses of violence—it’s imperative to have a clear objective and overview before getting down to the purely technical questions approaches. The true Ninja is compelled to act through a sense of personal responsibility, unlike the mercenary who has a narrow perspective. The ninja’s intuitive knowledge of his fated responsibilities allows him to do his part. The first step in raising a Ninja is to remove any mental or spiritual obstacle that would interfere with the ninja’s natural awakening.
+
+### Shochi
+
+Even the most talented Ninja are helpless without the guidance and direction of a capable leader. The third book, entitled **Shochi**, deals with the effective management of a Ninja organization and describes the various ways of successfully operating it. In addition, preventive measures are explained, which should make it impossible for enemy agents to sneak into the organization. Thorough knowledge of the balancing concept of _in_ and _yo_ (yin and yang) is extremely important to properly understand the art of the Ninja.
+
+### Yonin
+
+**Yonin**, the fourth of the ten volumes, contains the Yo aspects, the _bright_ sides of Ninja techniques. Using the dynamic, positive power of his intellect and creative thinking, the Ninja can get the information he needs without having to take part in a spy mission. By allowing others to collect information for them, either directly or indirectly, they have all the important data they need to carry out a successful action. His knowledge of enemy strengths and weaknesses allows him to properly face the enemy while giving himself the appearance of having nothing to do with the whole thing and taking no action in that direction.
+
+### Innin
+
+The fifth, sixth, and seventh volumes of the Bansenshūkai are all titled **Innin**. Their common theme is the in-concept, the _dark_ side of Ninja knowledge. Subterfuge, deceit, confusion tactics, and surprise attacks are just some of the techniques presented in these volumes. Since the Ninja could use methods that the Samurai considered dishonorable, despicable, even cowardly, he also made extensive use of disguises and nocturnal actions. He sneaked into the opposing camp using a ruse to kidnap or kill commanders and bribed key officials to help him achieve his goals. All variants of this unique Ninja combat system, from single combat to complete plans of surprise attacks for whole battle groups, are contained in the mentioned volumes.
+
+### Tenji
+
+**Tenji**, the eighth volume, contains the methods by which the Ninja can correctly assess the environmental conditions. Techniques that allow one to predict the weather, tide tables, moon phase tables, and various methods of orientation and navigation are among the knowledge presented in the Tenji volume. These are partly centuries-old experiences with systems such as the _gogyō setsu_ (theory of the five elements), the _inyōdō_ or the oracle _eki_ and partly scientific observations or Indian, Tibetan, or Chinese methods to predict trends and events.
+
+### Ninki
+
+**Ninki**, the description of the Ninja gear, begins in volume nine and continues through volume ten, which is however labeled _closing volume_ and not _tenth volume_. Perhaps this is because the Ninja saw the number 9 as a means of inspiration and enlightenment.
+
+In the ninth volume, you will find the climbing tools of Ninjutsu under the title _toki_. Everything is listed here that can help the Ninja to safely climb and descend fortress walls, trees, cliffs, and ship walls. _Suiki_ takes charge of the Ninja’s water equipment; it is based in large part on practical advice from pirates. The methods presented in this chapter allow different types of river crossing or show ways to move further underwater. _Kaiki_ is about tools that can be used to break into closed buildings, castles, fortifications, or warehouses. Equipment is described for picking door locks, drilling holes in walls, or removing doors from their hinges. The fire techniques, _kaki_, complete the Bansenshūkai. Here you will find a whole range of formulas for the preparation and use of explosives, smoke bombs, medicines, narcotics, and poisons.

+However, contemporary Ninjutsu students are in no way discouraged from practicing other training aspects not included in this list. Any martial art, other than a Zen-like _dō_ art, which is not at all interested in practical applications but stubbornly confines itself to a certain number of techniques, such as presenting 106 weapons and 42 chokeholds to its followers, will inflict severe damage on the students involved because they only think in methodical, orderly structures as soon as danger arises. Through mechanistic training, the mind is encouraged to compare each new situation that arises with previous training sessions and to classify it into a certain category. So it’s understandable that using items or tactics that aren’t on this list could easily be overlooked.

+---
+
+The Ninja also needed to know these strategies so that he could give advice to his general and see through the enemy’s strategies.
+
+## Gankō – Flight of Birds
+
+{% figure %}
+
+
+
+{% endfigure %}
+
+This is a flexible arrangement of troops that can easily be altered should the need arise. A dense line of archers protects the front and rear, but there are also plenty deployed on the sides in case the enemy changes position. The general is at the back with his staff, but still close enough in the center to allow for smooth communication.
+
+## Hoshi – Arrowhead
+
+{% figure %}
+
+
+
+{% endfigure %}
+
+This formation is intended for a heavy attack. A thin line of arquebusiers leads the vanguard of the Samurai. These thrust into the gaps that the arquebusiers have shot in the enemy lines. This formation is highly mobile, which is why the drummers and flag bearers are positioned around the general’s retainers. The formation is intended for fast attacks, which is why the flanks are only lightly defended by bowmen and spearmen.
+
+## Saku – Keyhole
+
+{% figure %}
+
+
+
+{% endfigure %}
+
+This formation is the best defense against Hoshi. Six ranks of arquebusiers, supported by two ranks of archers, are set up in front of the hole to receive the arrowhead. The form of the Samurai, which gives the formation its name, is very stable against such an attack.
+
+## Kaku yoku – Crane Wing
+
+{% figure %}
+
+
+
+{% endfigure %}
+
+This formation is best for surrounding the enemy. Arquebusiers and archers weaken the opponent’s attack. After that, the enemies meet the formation of Samurai, which is built like a wing.
+
+## Koyaku – Cattle Yoke
+
+{% figure %}
+
+
+
+{% endfigure %}
+
+This formation is best for catching the Cranewing, but especially for catching the Arrowhead. The second and third companies can quickly form a keyhole to effectively combat the arrowhead.
+
+## Gyorin – Fish Scale
+
+{% figure %}
+
+
+
+{% endfigure %}
+
+This formation is used when outnumbered by enemy troops. Mainly this formation is a blunted arrowhead, not all the force is put into the attack, but some is retained for safety.
+
+## Engetsu – Crescent
+
+{% figure %}
+
+
+
+{% endfigure %}
+
+If your troops have their backs to the wall, the general uses this formation. Although the army has not yet been surrounded, it has already taken heavy losses. The battered units are pulled back while the vanguard of the Samurai forms a crescent that can easily be adjusted as the situation demands.
+
+## Chōda – Long Line
+
+{% figure %}
+
+
+
+{% endfigure %}
+
+This formation works best when your troops are being attacked from two different sides. The soldiers can quickly switch in both directions.
+
+But this is only a small selection, there are numerous other formations and variations of those shown. The tiger head is used when you want to use the flight of the birds, your troops but are only half as strong, the lying dragon is a variation of the tiger head when fighting on the hill.

+title: "Body Weapons"
+priority: 325
+date: 2006-03-28T17:32:00+02:00
+author: "Stefan Imhoff"
+excerpt: "There are numerous body weapons in Ninjutsu to attack muscles, tendons or bones. Fingers, fists, the edges of hands, feet or other parts of the body can be used for this purpose."
+translationKey: "bodyWeaponsPage"
+categories:
+ - training
+ - weapons
+---
+
+## Locks, Punches, Kicks
+
+The martial art of _taijutsu_ is a fighting method that does not only consist of punches, throws, or holds. The whole body is used as a defensive weapon. The Japanese word _ken_ is a term for all-natural weapons. Just as combat stances are constantly adapting to circumstances, natural weapons are constantly adapting to the situation. Gripping hands become fists, and maybe claw hands again. And kicking feet might turn into knee kicks. The hip and shoulder are used for leverage and ramming.
+
+Another distinctive feature of Ninjutsu is that it uses the dynamics of natural weapons. It doesn’t just use pure muscle power to deliver a powerful punch, but a combination of body energy, body balance, and breath control to produce a terrifying, knock-down effect. This natural power, combined with speed and scientific knowledge of the human body’s weak points, becomes a deadly and effective weapon.
+
+## Kikaku ken – Demon Horn
+
+{% figure "Kikaku ken – Demon Horn" %}
+
+
+
+{% endfigure %}
+
+The bony structure of the head – especially the forehead – is used to slam, jab, ram, or stretch the enemy’s joints. When grabbed from behind, you can inflict excruciating pain on the back of your enemy’s head by slamming your head back into their face. The head can also be rammed against the breastbone or chin.
+
+## Shuki ken – Elbow
+
+{% figure "Shuki ken – Elbow" %}
+
+
+
+{% endfigure %}
+
+The bone structure of the elbow can be used against the bones of the arms, torso, head and it can press on sensitive points on the body. With the swing of the whole body, the elbow becomes a formidable weapon even in close combat.
+
+## Sokki ken – Knees
+
+{% figure "Sokki ken – Knees" %}
+
+
+
+{% endfigure %}
+
+The knee is used similarly to the elbow against the limbs, torso, and head. The knee also reaches places on the enemy’s body that are difficult to reach for punches or kicks.
+
+## Shitō ken – Finger Sword
+
+Also Hisoken (_Hidden Spear_)
+
+{% figure "Shitō ken – Finger Sword" %}
+
+
+
+{% endfigure %}
+
+The tip of the thumb is used to stab semi-soft targets on the enemy’s body and apply pressure to sensitive points. Especially zones where muscles covering the bones like the arms, ribs, and neck are attacked with the thumb.
+
+## Shishin ken – Finger Needle
+
+{% figure "Shishin ken – Fingerpin" %}
+
+
+
+{% endfigure %}
+
+The _Fingerpin_ is used at short range against soft or semi-soft targets such as the face, neck, solar plexus, or forearm.
+
+## Shitan ken – Finger Ends
+
+{% figure "Shitan ken – Finger Ends" %}
+
+
+
+{% endfigure %}
+
+The fingers are used as hooks to tear, grab or crush the enemy’s sensitive zones. The fingertips support the pressure and the fingernails increase the pain. This weapon works well against the neck, hand, or eyes and mouth.
+
+It is still available in different variations (_san shitan ken_, with three fingers) or supported by the thumb (_shi shitan ken_, _san shitan ken_).
+
+## Kiten ken – Create a Turn
+
+{% figure "Kiten ken – Create a Tack" %}
+
+
+
+{% endfigure %}
+
+The edge of the open hand can be used against bones of the arms, legs, neck, and head. The punch is set at a 90° angle in the hand and opened just before the target. The whole body is placed behind the punch and only touches the target a short fraction, but that should be enough to knock him off his feet.
+
+## Gyokakuken – Horns United
+
+{% figure "Gyokakuken – Horns United" %}
+
+
+
+{% endfigure %}
+
+Index finger, middle finger, and ring finger are shaped like a trident. The tips of the fingers can be used to stab soft parts of the body, such as the neck.
+
+## Shu ken – Beak
+
+{% figure "Shu ken – Beak" %}
+
+
+
+{% endfigure %}
+
+All fingers are centered on one point, giving the hand the shape of a beak. With the concentrated power of all fingers in a relatively small area, this punch is particularly useful on muscles and pressure points.
+
+## Shikan ken – Finger Ring
+
+{% figure "Shikan ken – Finger Ring" %}
+
+
+
+{% endfigure %}
+
+The knuckles are used against the large areas of the bones, e.g. the lower ribs, sternum, and face. The fingers are folded in half and the knuckles of the middle fingers are used as a weapon. The whole body is placed behind the punch and the knuckles shoot straight to the target.
+
+There are variations of this fist, whereby two, three, four knuckles can also be used.
+
+## Koppō ken – Bone
+
+{% figure "Koppō ken – Bone" %}
+
+
+
+{% endfigure %}
+
+The fist is held as in _fudō ken_, only the thumb is at the side and the knuckle of the thumb hits the target.
+
+## Shako ken – Crab
+
+{% figure "Shako ken – Crab" %}
+
+
+
+{% endfigure %}
+
+The fingers are spread and bent so that the hand forms a claw. This weapon is used against the soft parts of the body. The palm is used for ramming or breaking, and the fingers for raking. The face, neck, abdomen, groin, muscles of the upper body, and inner thighs are effective targets for this weapon.
+
+## Happa ken – Eight-Leaf
+
+{% figure "Happa ken – Eight-Leaf" %}
+
+
+
+{% endfigure %}
+
+This fist is the palm of the open fist. You can hit both ears at the same time with the palm of your hand, tearing the eardrum.
+
+{% banner "Warning" %}
+
+**Never** – not even cautiously – use in training or non-life-threatening altercations, the blow may cause irreparable damage to the eardrum!
+
+Takamatsu Sensei suffered from hearing loss throughout his life after being hit in the ear.
+
+{% endbanner %}
+
+## Fudō ken – Immobile
+
+{% figure "Fudō ken – Immobile Body Weapon" %}
+
+
+
+{% endfigure %}
+
+The _normal_ fist is pounded against bone. She can hit with different zones: the front, the bottom, the outside, etc. This can break the bones and knock the opponent down.
+
+## Soku yaku ken – Dancing Foot
+
+The bottom of the heel and the sole of the foot are used to kick into the enemy’s semi-soft or hard zones. The step can be used against the knee, where he is then kicked down from above, or against higher areas. The kick is not kicked and quickly withdrawn, but _kicked_through_ the enemy.
+
+## Zenpō geri – Forward Kick
+
+{% figure "Zenpō geri – Forward Kick" %}
+
+
+
+{% endfigure %}
+
+Straight kick forward. Can be kicked at different heights. The heel or bottom of the foot hits the target.
+
+## Sokuyaku suiteiken – Horizontal Kick
+
+{% figure "Sokuyaku suiteiken – Horizontal Kick" %}
+
+
+
+{% endfigure %}
+
+The leg is kicked forward horizontally, the foot hits the target sideways.
+
+## Sokuhogeri – Side Kick
+
+{% figure "Sokuhogeri – Side Kick" %}
+
+
+
+{% endfigure %}
+
+The leg is kicked out sideways, the upper body remains facing forward.
+
+## Kō ken – Hook
+
+{% figure "Kō ken – Hook" %}
+
+
+
+{% endfigure %}
+
+The leg is kicked backward in a hook-like manner, e.g. tripping an opponent.
+
+## Kōhōkeri – Back Kick
+
+{% figure "Kōhōkeri – Back Kick" %}
+
+
+
+{% endfigure %}
+
+The leg is kicked out backward with the upper body lowered.
+
+## Kagi kōhō keri – Back Hook Kick
+
+{% figure "Kagi kōhō keri – Back Hook Kick" %}
+
+
+
+{% endfigure %}
+
+You step backward and hit with the sole of your foot. Can be used when freeing from a hold.
+
+## Kata ashi tobi keri – One-Legged Jump Kick
+
+{% figure "Kata ashi tobi keri – One-Legged Jump Kick" %}
+
+
+
+{% endfigure %}
+
+Jump off with one leg and direct your body and arms in the direction of the jump.
+
+## Ryo ashi tobi keri – Two-Legged Jump Kick
+
+{% figure "Ryo ashi tobi keri – Two Leg Jump Kick" %}
+
+
+
+{% endfigure %}
+
+Jump off with both legs and keep them together during the jump. The jump is very difficult but also very effective because the whole body hits the opponent.
+
+## Ryo yoku keri – Two-Legged Wing Kick
+
+{% figure "Ryo yoku keri – Two-Legged Wing Kick" %}
+
+
+
+{% endfigure %}
+
+This kick is most commonly used when leaping down on the enemy from a high vantage point.

+
+## Ryū
+
+Little is known to the general public about true Ninjutsu. Many think that Ninjutsu is a martial art, like karate or judo. But that’s not the case. Ninjutsu or Ninpō is the generic term for different styles, schools, and views of Ninjutsu. Each of these Ryū had different techniques, wisdom, and specialties. During the _sengoku jidai_ there were probably around 250 different Ryū, some of which had their fighting styles, but sometimes several Ryū had the same or similar fighting styles.
+
+However, most of the Ryū were gone by the end of the war. Some were no more than mercenaries, assassins, or spies.
+
+I think it is important to accept this point. Often Ninja teachers and historians try to emphasize that Ninja were only scouts. But that is wrong. Just like today, the balance of _in_ and _yō_ used to be balanced. Some unscrupulous people would accept any job for money, as well as Ryū under the wise guidance of a _jōnin_. In such a time of war, it was important to guide a Ryū with philosophical foresight, for the difference between foe and friend could change in the blink of an eye.
+
+However, we do not identify with the crimes that have been committed in the past but take the ideals of the teachings that stood at the beginning of the Ryū as a model.
+
+Honesty, humility, humor, strength, curiosity, self-control, understanding, and altruism. A Ninja always lives by the rule that happiness, joy, and personal fulfillment are inherent rights of every human being, regardless of race, religion, or beliefs.
+
+Our task is to preserve these ideals and to ensure that these ideals are adhered to. We focus our entire lives on maintaining peace in word and deed. Ultimately, this can also mean having to fight, but a true Ninja tries the path of non-violence first.
+
+## The Nine Schools
+
+under dr Hatsumi Masaaki summarized nine different schools that have been passed down from teacher to student for generations. In honor of his teacher Takamatsu Toshitsugu, he named the summary of the 9 Ryūha Bujinkan. _Bu_ means war, _jin_ means god, heart, or soul, and _kan_ means palace, building, or great house. So one possible translation is _the hall of the god of war_.
+
+{% figure "Bujinkan Logo" %}
+
+
+
+{% endfigure %}
+
+The oldest schools look back on a good millennium past. The techniques have been used often enough over time to test and prove their functionality and effectiveness. Ninjutsu is not a Zen system, the technique is not the goal, but solely a quick and effective defeat of opponents. There are no fancy techniques or superfluous movements, Ninjutsu is effective and does not have to compete with any other martial art.
+
+The nine Ryūha of the Bujinkan are:
+
+1. Togakure-Ryū Ninpō
+2. Gyokko-Ryū _koshi jutsu_
+3. Kukishinden-Ryū _happōhikenjutsu_
+4. Shinden Fudo-Ryū _daken taijutsu_
+5. Gyokushin-Ryū Ninpō
+6. Koto-Ryū _koppō jutsu_
+7. Takagi-yoshin-Ryū _jutaijutsu_
+8. Gikan-Ryū _koppō jutsu_
+9. Kumogakure-Ryū Ninpō

+---
+
+## Fukuro-gaeshi zenjutsu
+
+If the Ninja managed to intercept a message between the enemy lord and his allies or relatives, he would forge the message and send it on its way again. He may have succeeded in completely intercepting and controlling the two-way correspondence. In this way, he managed to sow distrust and hostility between allies.
+
+## Geinyujutsu
+
+With this tactic, the Ninja invaded enemy territory, causing confusion and spreading fear and terror. He foresaw the enemy’s troop movements and immediately countered them. Or he spread false rumors, encouraged malcontents to revolt and riots, set fire to strategically important positions, and sowed distrust among the soldiers. He stole horses, weapons, and food or rendered them useless. If the enemy wanted to enter a village, he would already run ahead and spread panic among the inhabitants.
+
+## Katagataejutsu
+
+If the enemy left his camp, the Ninja took this chance and sneaked into the camp. He sabotaged important facilities in the camp, spread panic among the remaining guards, and opened the gates to his troops.
+
+## Ryohanjutsu
+
+The Ninja could also kidnap key figures to enforce his terms. He blackmailed key figures into serving him or the kidnapping victim would be executed.
+
+## Ryakuhonjutsu
+
+With this tactic, the Ninja sneaked into the enemy camp and pretended to be an ally there. Of course, this required that the Ninja was already known and well versed in the area.
+
+## Suigetsujutsu
+
+With this tactic (_moon in the water_) the Ninja staged a diversionary maneuver. A squad of Ninja or part of the regular army launched a mock attack on one point of the fortress. While everyone rushed to the threatened spot, the Ninja climbed over the wall at the unattended spot.
+
+## Yojajutsu
+
+With this tactic, the Ninja took on the appearance of a defenseless and unsuspecting person. He disguised himself as a beggar, cripple, blind, deaf or deaf-mute and tried to find shelter in the castle. He could also get into the castle with jugglers or traders.

+
+## First Mention of Espionage
+
+The first mention of espionage (_chōhō_) is in Sun Tzu’s
The Art of War, the Chinese classic on warfare. In ancient China, it was common to achieve victory with incredible numbers of troops. But the consequences were catastrophic for the landscape and structure. Countless, long, bloody battles lasting several generations were fought, killing thousands.
+
+> Raising a host of a hundred thousand men and marching them great distances entails heavy loss on the people and a drain on the resources of the State. […] Hostile armies may face each other for years, strivingfor the victory which is decided in a single day. This being so, to remain in ignorance of the enemy’s condition simply because one grudges the outlay of a hundred ounces of silver in honours and emoluments, is the height of inhumanity.
+>
+> **Sun Tzu**, _The Art of War_
+
+{% productshelf %}
+{% product "081331951X", "The Art of War", "en" %}
+{% endproductshelf %}
+
+Even today, generals often prefer long campaigns with high human and material costs. Positions are excavated and people entrench themselves. But a single spy or saboteur’s accomplishments could shorten the war by years.
+
+## Laws on Warfare?
+
+War is an unacceptable state of affairs, and a Ninja could never allow his master to start a war. However, when the freedom of one’s country is being attacked by others and one is forced to defend oneself, a Ninja strives to do whatever it takes to end the conflict as quickly as possible.
+
+It is therefore questionable what kind of world we live in when rules for war are being established today. It’s not a game!
+
+Of course, it is understandable that some rules need to ensure that civilians are protected from massacres, but it is questionable whether rules are of any use when dictators and tyrants do not comply with them anyway. And as always, the victor of war decides on punishment. Because winners will probably have to answer before any court in the rarest of cases.
+
+So I find it very concerning that espionage and sabotage are considered vile and contemptible in these laws of war, but long-range missile launches, tank battles, and infantry are considered part of _normal_ warfare.
+
+## Espionage to Shorten the War
+
+It has been proven time and time again that these _despicable_ spies have saved the lives of hundreds of thousands of soldiers. They restored the balance of nuclear power, stole the Enigma machine, and saved thousands of supply ships from being sunk. The famous British _Commandos_, by their acts of sabotage, gave Britain a respite after the German invasion. They blew up ship and submarine yards, scouted targets for the bombers, and prevented weapons of mass destruction like V2 from going into mass production. And a German spy found out for the Russians that the Japanese were not planning an invasion of Russia. In this way, Stalin was able to send his troops to Germany with all their strength and end the war with the help of the Allies.
+
+Everyone should think about this and think about who defines right and wrong and what interests they are pursuing.
+
+## Anonymity
+
+An important basis for espionage is anonymity. This was the Ninja’s recipe for success, which was also called (_mumei mugei no jutsu_, Engl.
No art, no name
). To protect his anonymity, the Ninja made sure no one knew his real face.
+
+When threatened with capture, he has cut his face to avoid identification or cut out his tongue to avoid revealing anything. Sometimes two Ninja were together on a mission. If one was caught, the other had the order to kill his comrade.
+
+A principle of the Ninja (_yomogami no jutsu_, Engl.
a hairstyle, viewed from four different sides, must always look the same
) states that one should always choose several names and identities. The famous _jōnin_ Momochi Sandayu even had two different families with children and a house. He was also the _jōnin_ Fujibayashi Nagato. So one person led two different groups of Ninja.
+
+The reason for espionage is to gain an advantage in war. You can find out the strength, armament, etc. of the enemy as pure reconnaissance, and thus plan your campaigns better.
+
+## Types of Espionage
+
+This can be divided into two areas: espionage in peacetime (_tōiri_) and espionage and sabotage during the war (_chi kai ri_).
+
+When spying or planning an act of sabotage, there were six different points to consider for the successful completion of a mission:
+
+## Place a Ninja
+
+A Ninja had to remain unnoticed and unnoticeable throughout their mission. To do this, he had to adopt the most normal appearance possible.
+
+One possibility was to place agents in possible war or unrest areas during peacetime. It was certainly far easier to assimilate into and subvert a society in times of peace.
+
+The Ninja settled into his area of operations and became a part of society. He made contacts, sounded out possible allies, held a lot of conversation, observed objects, and worked his way into the necessary information.
+
+Whenever possible, he and his agents filled important key positions in the military or communications. In times of war, this is hardly possible because the checks are too strong.
+
+He could also draw maps, enabling troops to move more easily in times of war.
+
+Another option was to confuse the enemy or leave them in the dark. A sense of security was created in his mind. You could have an agent intercepted with information. The informant then carried documents with him, but they only contained false or incorrect information. In this way, you could get rid of a traitor in your ranks if you knowingly provided him with false information.
+
+## Spies
+
+Five different types of spies could be used on an espionage or sabotage mission:
+
+- **Native Spies** – He was at home in the area of operations and therefore knew the geography, language, customs, and inhabitants. Such a spy was not easy to disguise because he was well known.
+- **Inside Spies** – Recruiting a spy from the opposing team was called an Inside Spy. Men who had been demoted, criminals who had been punished, greedy people.
+- **Surviving Spies** – If a spy entered enemy territory only for the duration of his mission and returned home after completing it, that was called a surviving spy.
+- **Defected Spies** – An enemy spy who had switched sides and was now working for your side was called a defected spy or double agent. However, such an agent is always a big risk because his loyalty could change again and he could only be a double agent for the other side.
+- **Doomed Spies** – A spy who for whatever reason fell out of favor with his master, or who turned out to be a traitor or double agent, was sent to his death. You could supply him with false information for a while beforehand and then you could usually use him to carry out one last ruse with his help.
+
+## Kunoichi
+
+You could also position _kunoichi_ in the enemy’s area of operations. They were usually not touched and could get closer to generals and Samurai. They used their intuition, psychology, and manipulation to achieve their goal. A distinction was made between two different types of _kunoichi_:
+
+- **Shimma kunoichi** – This _kunoichi_ was a female member of a _Ninja-Ryū_. She had received combat training and had been trained in special tactics and strategies. Usually, a male _kantō kusha_ (commander) led a group of _kunoichi_. He supported them, took their information, and helped them when an escape was needed.
+- **Karima kunoichi** – There were numerous women who knowingly or unknowingly brought information to the _kunoichi_. This _kunoichi_ had seldom received brief instruction in espionage. Both women from the castle area and women of lower status (prostitutes, farmers) kept a _kunoichi_ as informants.
+
+## Using the Services of Traitors
+
+Another possibility was to use the enemy’s people for his purposes. The dissatisfied were sought out and instigated to betrayal. This became the principle of _gojō goyoku_ (manipulation by the five desires). Of course, one high-ranking traitor was far more valuable than another. But the Ninja also sought help and support from the population, mostly in times of peace. This is how a Ninja could support a family financially in peacetime. In times of war, this had to be at his service. They had to give the Ninja their house as a shelter, perform minor informant and espionage duties, or perhaps even give their daughter to the enemy prince as a concubine to gain access to the fortress.
+
+Sometimes two agents were sent on the same mission without the knowledge of the other. On the one hand, you had greater objectivity to what was happening, on the other hand, you could easily unmask double agents in this way.
+
+Once you uncovered an enemy agent, you could feed them false information for a while and then discredit them with their masters by blatant deception, either killing them or defecting to them.
+
+One could also use one’s agent, who parted with his old master after an apparent quarrel or for higher money. He enlisted with the enemy and worked for them for a while. It is even said that a Ninja killed some Ninja of his clan on behalf of the enemy master before he completed his task and returned to his old master.
+
+A favorite tactic of the Ninja (_kami gakure no jutsu_, Engl.
the art of hiding behind God
) was to use detours to approach the goal. If the target object was too heavily guarded, then the Ninja found out about the relatives of his target object in the Buddhist or Shintoist temple. He tried to befriend a relative or close confidante. In this way, sooner or later, he came close to his goal.
+
+## Determine Goals
+
+Next, the Ninja had to figure out the enemy’s targets. For this purpose, a team observed the enemy territory over a longer period.
+
+Closer spies might know more about the enemy’s plans. He gained access to top-secret rooms and documents and tried to see through his opponent.
+
+## Determine Strategies
+
+Then the enemy’s strategies had to be recognized and analyzed. One had to find out which people held key positions, which codes and keywords were used by the guards, how supplies reached the enemy, which routes and routes were used by patrols and soldiers. And the Ninja had to expose and, if possible, hinder or destroy the enemy’s espionage system.
+
+## Sowing Confusion
+
+You had to confuse the enemy and confuse them with false information, rumors, and fake communications. During this phase, the Ninja also attempted to encourage discord and discontent among the soldiers, playing them off against one another. For example, he could come as a _survivor_ into the castle of the enemy and tell of a campaign, of troops and movements that in reality did not take place or took place somewhere else. Or he frightens the soldiers with reports of nocturnal murders in other camps. In this way, the soldiers could no longer sleep and their motivation and readiness dropped.
+
+## Determine Tactics
+
+The Ninja also lay down on observation posts to find out the battle tactics, battle strategies, strengths, and weaknesses of the opponent. He figured out how to place and move his troops, explored troop strength, armament, and the enemy general’s secret techniques and tactics. He found out where and when supplies were arriving and if there were other troops nearby to support them. If a commander had bad tendencies in warfare, the Ninja would support those tendencies.
+
+If he for example splintered his forces, this process was encouraged, if his front was weak, then one tried to urge the general to charge through the weak front. If the enemy had a strong center, the Ninja advised the general to hit the sides and roll up the troops from behind.
+
+## Counterintelligence
+
+At the same time, he had to try to keep his strategies secret from his opponents. _Important_ documents were sent to a possible suspicious person and one waited to see how they reacted (_yamabiko shicho no jutsu_, Engl.
the art of listening for the echo
). Once the enemy spies were identified, it was a matter of deciding whether to eliminate them or let them live. If he was allowed to live, of course, he was being given false information on purpose. The fighting techniques of the Ryū were also kept strictly secret. In some Ryū, there were even techniques to show to strangers that were invented solely for deception.
+
+You convinced your general to try out new techniques and issue non-standard orders. In this way, one could leave the enemy in the dark about the truth until the decisive moment.

+
+{% figure "Ashikō" %}
+
+
+
+{% endfigure %}
+
+The counterpart to the _shukō_ (hand claw) is the _ashi kō_. A device similar to that on the hand was placed under the Ninja’s foot. Getting kicked made worse injuries that way, and climbing was far easier.
+
+## Ippon sugi nobori
+
+{% figure "Ippon sugi nobori" %}
+
+
+
+{% endfigure %}
+
+_A way to climb up a cedar_. With this tool, the Ninja could climb trees. The iron prongs were used to pull the rope a little bit higher. In principle, it works exactly like the tool used today to climb telegraph poles.
+
+## Kagi nawa
+
+{% figure "Kagi nawa" %}
+
+
+
+{% endfigure %}
+
+This grappling anchor was attached to a rope and with its four sacks it easily got caught in an obstacle on a tree or building.
+
+## Kagi yari
+
+{% figure "Kagi yari" %}
+
+
+
+{% endfigure %}
+
+Togakure-Ryū Ninja often used the hooked spear. You could get into trees, over walls, or onto ships. It was also possible to get from tree to tree in this way. Hidden on a high post, a victim could be caught with the hook and pulled up. It was also suitable for fishing, breaking down doors, or transporting luggage.
+
+## Kasha

+
+## Musubi nawa
+
+A horsehair rope. Ropes were often made of hair, including women’s hair because these were very tear-resistant.
+
+## Ninja tō
+
+{% figure "Ninja tō" %}
+
+
+
+{% endfigure %}
+
+The short sword was an important tool in Ninja equipment. It wasn’t pretty or valuable like the _tachi_ or _katana_ of the Samurai – it was useful. The blade was much shorter than that of the _katana_ or the _tachi_. So the Ninja could move better with it and use it in close combat. The blade was sometimes straight, but sometimes it was just a shortened _katana_. The _tsuba_ (hand guard) was not decorated with beautiful ornaments but mostly larger and made of simple steel, often angular. So you could use it as a climbing aid. The sword was carried at the side and only rarely (e.g. when climbing) over the back or stomach. Poisons, medicines, or chemicals were often hidden in the handle. The _saya_ (scabbard) could be used as a blowgun or breathing tube.
+
+## Shukō
+
+{% figure "Shukō" %}
+
+
+
+{% endfigure %}
+
+A terrible weapon is the _shukō_. A pointed iron prong was attached to a kind of leather arm ring, whereby the Ninja turned his hand into a tiger claw. The spikes could inflict terrible wounds on the attacker’s face. With this weapon, Ninja could also _take swords_, i.e. stop the sword strike. At the same time, the Ninja could climb up walls or trees better. The counterpart for the feet was called _ashi kō_.
+
+## Taka bashigo
+
+{% figure "Taka bashigo" %}
+
+

+
+## Yari
+
+{% figure "Yari" %}
+
+
+
+{% endfigure %}
+
+The Japanese spears were designed to stab and were rarely thrown. With its small point, one could easily hit between the plates of the Samurai armor. The tips were mostly two- or three-sided. It was usually 200 to 350 cm long. Oda Nobunaga used _yari_, some 640 cm long, to protect his _teppō_ soldiers against cavalry.
+
+The Ninja often used the _yari_ to high jump over walls or people.

+priority: 310
+author: "Stefan Imhoff"
+excerpt: "Various mental and physical aspects such as breathing, rhythm or flow are part of Taijutsu and should be considered for a successful outcome of a fight."
+translationKey: "combatFactorsPage"
+categories:
+ - strategy
+ - tactics
+ - training
+---
+
+## Nagare
+
+The principle of flowing action (_nagare_) is one of the most important principles in training. Without a _flow_, the techniques appear choppy and are performed independently. Without the principle, one will try with all one’s strength to adapt a technique to a situation. Because there is no fluid adaptation, only muscle and bone strength is used.
+
+## Renzoku
+
+The combination of several techniques is called _renzoku_. In this way, continuity of techniques arises from the succession or chaining of individual techniques. Only in this way does the individual technique become effective and efficient.
+
+## Ritsudo
+
+Closely related to the flowing action is _ritsudō_. Rhythm is the interplay of two or more individuals. Rhythm is the course of a struggle, the transition from one phase to another. Attack, defense, forward movement, and backward movement. The defender must adapt to the attacker’s movements. The emotional levels of the two opponents, their muscle tension, and muscle relaxation are also part of the rhythm. Rhythm is nothing but the game of cause and effect in combat. An attack follows a defense, which in turn creates an attack – until the fight is over.
+
+## Undō
+
+_Undō_ means movement. This term also includes technique and body movement. The body movement is divided into two areas:
+
+- **Shishi undō** (extremity movement)
+- **Tai sabaki** (trunk movement)
+
+## Kokyūhō
+
+Neglected by many, _kokyūhō_ (breathing) is an important component of combat. Most adults breathe through their chests or even through their throats. But this kind of breathing is unnatural.
+
+> The true man breathes with his heels; the mass of men breathe with their throats.
+>
+> **Chuang Tzu**
+
+Both children and _real_ people breathe with the diaphragm, i.e. perform abdominal breathing. In this way, the body remains calm and relaxed and the organs are also massaged and gently moved. Most people breathe through their mouths, which is very unhealthy. The nose should be used for both inhalation and exhalation as it filters, humidifies, and warms the air.
+
+When inhaling in abdominal breathing, the abdomen bulges outwards, when exhaling it bulges inwards.
+
+{% banner "Learn Abdominal Breathing" %}
+
+In the past, a simple exercise was used to learn abdominal breathing: you wrapped your stomach tightly with a cloth.
+
+As a result, you are aware of your breathing throughout the day and immediately notice when you switch to chest breathing.
+
+After a few days or weeks, the cloth is no longer necessary because the body has become accustomed to abdominal breathing.
+
+In a fight, breathing will make the difference between victory and loss. It is the key to proper contraction and relaxation (or tension), vigorous movement, and dynamic movement.
+
+{% endbanner %}
+
+## Maai
+
+Of incredible importance in combat is distance. So it is not advisable to be too close to a skilled fighter, but if an opponent needs space to execute his techniques, you will get close to him. One should avoid specializing in techniques that limit one’s range and therefore effectiveness. By moving in unexpected directions, one can give oneself a tremendous advantage. In this way you are freed from the primitive way of fighting, always standing in one spot and just blocking.
+
+## Kikaigaku
+
+The mechanics’ aspect includes the body’s most effective responses to an attack. This includes footwork, side dodges and combat distance, proper use of body weapons, and effective techniques and strategies.
+
+## Doteki
+
+This aspect is the most effective application of mechanics, which involves the proper use of energy, rhythm and flow, strength and flexibility, speed ratios, and the ability to _feel_ and conform to an action.
+
+## Ito
+
+The intention is the clearly recognized goal: victory, the complete subordination of mechanics and dynamics. These include the attitude to use a violent technique, an irrepressible will to win that transcends fear and limits, and an attitude that not only sees victory as the only possible outcome but also sees defeat as a possibility.

+> In the first state, man and sword become one and each other. Here, even a blade of grass can be used as a lethal weapon.
+>
+> In the next stage, the sword resides not in the hand but in the heart. Even without a weapon, the warrior can slay his enemy from a hundred paces.
+>
+> But the ultimate ideal is when the sword disappears altogether. The warrior embraces all around him. The desire to kill no longer exists. Only peace remains.
+>
+> **Qin Shi Huang Di (Chen Daoming)**, [Hero](https://www.themoviedb.org/movie/79) (2002)
+
+## First Rule
+
+Life is meant to be so constructed that the enemy never thinks to appear in front of you. This goal can be attained through mental training.
+
+It can happen that your own spiritual charisma is not sufficient to prevent a dangerous situation from arising. But then there is still the possibility of successfully overlooking the danger. In concrete terms, this means that you can suppress your own feelings so that a threatening situation can be taken up without sympathy. That way you’re clear-headed and can really think about your reactions.
+
+> I must not fear. Fear is the mind-killer. Fear is the little death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain.
+>
+> **Muahdib (Frank Herbert)**, _The Desert Planet_
+
+Normally one feels a strong sense of uneasiness until a dangerous situation has passed them by. However, if you stand up and put a quick end to the threat, you can quickly return to a relaxed, calm position.
+
+Learning and enduring situations where one must accept defeat, fear, or humiliation in order to achieve what one wants are ingrained in Ninjutsu. The syllable _nin_ means endurance, endure, endure, get along with. This is one of the hardest exercises because it takes a lot to persevere in the face of death.
+
+## Second Rule
+
+It’s important to get over your feelings so that you don’t automatically defend yourself when a defense isn’t necessary at all. This goal is achieved through mental training. If one fails to nip the threat in the bud, or at least let the threat pass without negative repercussions, then active defenses are considered.
+
+The principle **protect your opponent** counts here. Seriously wounding an opponent is often easier than just letting them run into nothing, or letting multiple opponents run into each other. If we try to protect the opponent, i. H. before his own deeds, we will not be able to be portrayed as evildoers if the opponent injures himself. If he hurts himself, we’ve got a clean slate.
+
+Many people think of physical fighting techniques first when they consider Ninjutsu. But in reality, they only come in third place. The struggle is the least suitable method for living a harmonious and natural life. By the time the battle starts, you’ve already suffered defeat. And **he who lives by violence will die by violence**.
+
+Nevertheless, training in Ninjutsu usually begins with physical training, since a solid knowledge of the physical conditions is a necessary prerequisite for mental growth. Hand-to-hand combat training can be used to get to know and understand one’s own feelings and moods in arguments.
+
+Nevertheless, it would be desirable if many fighters would devote themselves to the spiritual aspects of their art earlier.
+
+## Third Rule
+
+Perfecting one’s own physical abilities in such a way that any conflict can be successfully overcome is an important goal in one’s own development. This goal is achieved through physical training.
+
+Ninjutsu includes numerous elements of self-defense and a whole range of the body’s own weapons, which in combination with weapon techniques, dynamics, energy generation, and other aspects are fused into a unique combat system. It’s the same feeling when you perform a half-circle foot kick as when you perform a sword slash. Ninjutsu is therefore more a series of feelings than a collection of techniques.
+
+Because every human being is unique, both in stature and mental state, Ninjutsu does not force its students to imitate rigid series of movements. Rather, guidelines are given to develop natural emotional and physical responses.
+
+## Hints for a Fight
+
+If a fight is unavoidable, one should always keep the following points in mind:
+
+- It is important to always be one hundred percent. Consciousness is to be held as if nothing else existed in the world. Only the goal on which all concentration is directed is important. The mind must not wander.
+- The center of gravity should always be kept as low as possible, but the fluidity of the movements should not be impaired. The strength must not be concentrated in the shoulders or upper body.
+- The movements should be fluid and relaxed, the power is only released at the last moment. The techniques must not be performed with muscle tension from the start, otherwise, cramps will occur.
+- Full body weight should be placed behind each punch. Don’t try to counter with single limbs.
+- Never remain in a rigid position. The footwork should therefore be quick and appropriate.
+- It is important to breathe at the right rhythm to conserve and regain strength. Exhale while performing a technique, inhale during a retreat or preparation techniques.
+- Always pay attention to the line of sight and keep an eye on the opponent. It is important not to focus on your own technique so that you notice the changes in the opponent’s attack style.
+- Never lose sight of the meaning of the techniques used, never stick to a technique that has long since ceased to be appropriate.
+- Use every moment to increase personal knowledge and power. Don’t practice for the sake of practicing or to discipline yourself.

+author: "Stefan Imhoff"
+excerpt: "In addition to the five elements of matter, there is another important area for the Ninja – the mind and its abilities. This sixth sense is located between the eyebrows, slightly raised. This point is also called the ‘third eye’."

+---
+
+## The Mind as a Bridge to Consciousness
+
+The mind is a bridge between our consciousness and our body. He interprets the impressions received by the organism.
+
+Our universe consists of vibrations of different wavelengths. The solid matter has a very low vibration rate. Then comes noise, heat, electricity, light, and thoughts. Even within the phenomena, the different wavelengths determine how we perceive the phenomenon. With light the wavelength distinguishes the hue and, in the case of noise, the pitch.
+
+However, all these manifestations are dependent on the recipient and are received differently by different beings. Various animals hear in the range of ultrasound or see ultraviolet light. Recently it has even been proven that women can see more shades of red than men. This makes it possible for them to better recognize the feelings of others by the different shades of red on their skin.
+
+Wavelengths and vibration rates were not yet known to the Ninja of the Middle Ages, but it was clear to them that everything had its place somewhere in this universe. And thus also that no action is independent of another. Even phenomena that at first glance appear to be completely independent of others are connected in some way.
+
+The Ninja observed and manipulated their environment by bringing their thought waves into the same vibrational wave as their environment.
+
+## Enhance Your Senses
+
+To reawaken his senses, the Ninja first becomes aware of how much he put her to sleep in the past. Just as a natural movement is first learned in martial arts training, the natural perception of the senses is also reawakened. To reawaken smells, the Ninja spends a period of time paying close attention to all smells, the subtle nuances you don’t normally notice, as well as strong smells. Even _bad_ smells are simply perceived without evaluating them.
+
+In order to reawaken the sense of taste, the Ninja only pays attention to taste for a while and chews longer, more intensively, or expands his menu.
+
+In order to awaken the eyes, the Ninja pays particular attention to all visual impressions that he can perceive for some time. he concentrates on the different color nuances that e.g. the sky at sunset. He experiments with focusing the eyes, with different distances and shapes.
+
+The Ninja awakens the sense of touch by concentrating on touching his body, tension, heat, and cold or surfaces. During this period of time, he touches a particularly large number of objects and glides over their surfaces with his eyes closed.
+
+In order to regain hearing, the Ninja pays special attention to noise and music. He not only pays attention to the loud noises, e.g. street noise but also to the sounds that you would not normally hear. He tries to listen to the silence and to hear what the silence sounds like. Or he observes how his body reacts to different types of music.
+
+All of these mind-boosting exercises are meant to be just a suggestion, there are far more ways to improve your senses.
+
+## Sense Deprivation for Sense Expansion
+
+One can also enhance one’s senses through temporary sensory deprivation.
+
+Takamatsu Sensei reported that during his time of asceticism on a remote mountain, the solitude strengthened his senses to such an extent that he could smell when a human approached, he could even smell sex from afar.
+
+Some Ninja would not use spices or particularly spicy, salty, or bitter foods in order to be able to immediately identify poisoning in a dish.
+
+In the rainforest of South America, there were Indian peoples who lay down in water baths in dark chambers in order to switch off all sensory influences. In this way, they greatly improved their senses.

+## Live With All Your Senses
+
+It is important for a Ninja to surrender to his senses. Some perverted systems or religions want you to control yourself and give up those devilish cravings like good food, sex, or other sensual pleasures. But a fulfilling life includes all aspects that make up a living being. Our body and senses are a part of us, and it is wrong to indulge in self-denial, compulsion, or denial of pleasure in order to attain heightened awareness or a heightened level.

+
+It is difficult to explain what the Dao is. Because already in the first verse of Laozu’s work
Dao de jing it says:
+
+> The Dao that can be spoken of is not the ever-constant Dao. The name that can be named is not the ever-constant name.
+>
+> **Laotzu**, _Dao de jing_
+
+Daoism is a way of life that means moving with the times. This _natural run_ can be for example in the flowing water, in the flames of fire, the clouds that move in the sky.
+
+Especially today, when man strives more and more to dominate and control everything and thereby does terrible things, Daoism represents a good alternative.
+
+Unfortunately, this teaching remains closed to many people because the texts are almost always difficult to understand and of incredible depth. But it is worth looking into these old works by masters like Laotzu, Chunangtzu, Liehtzu, or other philosophers of that time.
+
+{% youtube "dFb7Hxva5rg" %}
+
+## Yin and Yang
+
+At the beginning of understanding, Daoism is the concept of the polarity of yin and yang. This principle is an important part of this teaching. The symbol of duality, with its white and black sides, has long been exploited as a popular commercial item by industry and the media. And many are sure to wear a necklace with this symbol without realizing its true meaning.
+
+{% figure "Yin and Yang" %}
+
+
+
+{% endfigure %}
+
+Again and again, misunderstood in the west, this symbol is not a sign for good and evil, for an eternal struggle of the two forces, for the Christian doctrine of heaven and hell. Rather, this symbol is a sign of a duality in which there is no _good_ or _bad_. One is just the flip side of the other. Without a _high_ there is no _low_, without _brightness_ there is also no _dark_. Both are just different aspects of the same system, and the disappearance of one would result in the disappearance of the other.
+
+The western world always tries to create a world where there is _joy without sorrow_, _wealth without poverty_ and _health without disease_, due to the Christian teachings. In Western medicine, the cause of an illness is not looked at, but mostly only the symptoms are treated. A Chinese doctor primarily tries to identify the cause of the disease and only then finds a way to restore balance.
+
+All inventions designed to bring us more of one automatically bring more of the other with them. No matter what we invent to make this world _better_, penicillin, nuclear power, cars, computers, etc., many things create as many or even more problems than they solve. Avoiding one aspect is not the point of Daoism. Both sides of the coin are correct because the universe accepts them. This aspect is difficult to understand at first, especially if you grew up in a Christian world.
+
+This is not to say that we reject technology, just that technology becomes destructive in the hands of humans who do not realize that they are part of the same process as all things in this universe.
+
+A simple example should clarify this. If a wise hunter shoots a monkey in the jungle one day, that’s enough for him and he goes home. A bad hunter would shoot any monkeys in the area enjoying a sumptuous meal. But if sometime later he wants to hunt a monkey again, he has to walk twice as far until he comes across monkeys again.
+
+Whoever sees himself separate from this universe and seeks to make it his own or subdue it is acting against the course of things. But sooner or later he too will fail and his attempt to control everything will fail.
+
+Winds, tides, currents, seasons, show the principle of becoming and passing away, a Daoist uses them and does not fight against them, but goes
with the flow
.
+
+## Dao
+
+
There is no other way but the way
. The Dao is the supreme reality and power of the universe, the reason for being and non-being. The Dao
does
nothing and yet leaves nothing
undone
. It cannot be defined in words and is neither an idea nor a term. It is not an energy that pervades the universe, nor is it a god. It may have created the gods or the god, but it is _not_ a god and not a creator.
+
+## Out of Itself
+
+Dao is what happens by itself (chin. _tzujan_), spontaneously and by itself and without compulsion.
+
+One cannot _follow_ or _not follow_ the way of the Dao. Perhaps one can imagine that one is outside the course of events, but this is only an illusion.
+
+So the Dao is the course of nature, the order of the universe. The Dao is self-generating and self-existing and is non-law.
+
+The harmony of the universe comes when all things are allowed to go their own way. In ancient China, there were a few rulers who governed their state according to the principles of the Dao. That means as few laws, penalties, and bureaucracy as possible. It is said that peace in the country was strongest at this time. But actually, every attempt to describe the Dao in words is doomed to fail from the start.
+
+## The Structure of the Dao
+
+However, the Dao has a structure and form. This is called _li_ in Chinese and is the asymmetric, non-repeating, non-regulated order. This order can be seen in flowing water, in the structure of tree bark, in ice crystals, pebbles on the beach, the muscle fibers, or in the form of galaxies. _Li_ is beauty that attracts us without being able to explain it. And there are no scientific explanations such as surface tension or mathematical laws that make up this principle.
+
+## Non-Action
+
+The principle of Daoism is _non-action_ (chin. _wu wei_). But it is not to be seen in the sense of inertia, laziness, laissez-faire, or passivity. Wu Wei does not mean going against the natural course of the Dao. Wu Wei is the willow that gives way under the weight of snow, and not like a tall tree that is rigid and whose branches break.
+
+A person who understands the Dao, whose lifestyle is Wu Wei. This principle was also used by the Ninja (_in shin tonkei_, maximum effect with minimum effort). A Ninja knew the principles of nature and humans so well that he used a minimum of energy in dealing with them.

+
+## Tokugawa Unifies Japan
+
+The last survivors had retreated further into the forests and mountains or fled to other clans throughout Japan. When Oda was assassinated in Honnoji in 1582, the Ninja under Hattori Hanzo helped Nobunaga’s ally Tokugawa Ieyasu get safely from Sakai, near Osaka, to his castle, Okazaki, near Nagoya.
+
+Because they had to avoid the dangerous Honnoji area, the only way was through the mountains of Iga and Kōga. Along with Ninja from Kōga, they aided Tokugawa, who became shogun in 1603 and whose clan controlled Japan for the next 250 years. Some families helped Tokugawa out of joy at Nobunaga’s death, others because they saw a peaceful future in Tokugawa. Ironically, it wasn’t a battle that marked the end of the Ninja, but peace. The Ninja aided Tokugawa in destroying the last of the Daimyō who opposed the ruling Tokugawa.
+
+## Ninja as Gardener and State Police
+
+With peace and order restored in Japan, the services of the Ninja were no longer in demand. Many _genin_ and _chūnin_ continued to work on their own, but without the philosophical guidance of the _jōnin_. Many of the Ninja were incorporated into the _bakufu_’s secret police, helping to oversee the imperial court and control the Daimyō. They were subordinate to the _ometsuke_, _bakufu_ officers of the state police. Others joined the military, many became criminals. At that time you could often hire former Ninja, but they were only thieves or murderers in Ninja clothes. They were often employed by rulers as gardeners or servants.
+
+These once deadly lone wolves degenerated into security guards, with miserable pay, and their duties soon became limited to opening doors or standing targets for young girls tossing snowballs.
+
+The few families who remained in the mountains outside of Kyōto hid from the Tokugawa.
+
+## The Last Missions of Ninja Warriors
+
+Only two more times Ninja services were needed. Once during the Shimabara Rebellion (1637-38) where Christians rebelled against religious and economic oppression.
+
+The last activity of the Tokugawa Ninja was in 1853 when the Ninja Yasusuke Sawamura was ordered to sneak onto Fleet Admiral Perry’s ships in search of information that would reveal the true motives of the alien barbarians.
+
+In the archives of the Sawamura family in Iga Ueno, there are still two letters containing a Dutch song about the quality of French women in bed and British women in the kitchen.

+priority: 105
+author: "Stefan Imhoff"
+excerpt: "For the Ninja, the Japanese Civil War created a great deal of demand for their skills, leading to the establishment of over a hundred schools in Japan."
+translationKey: "emergenceOfRyuPage"

+---
+
+## The Civil War in Japan
+
+With the advent of the Samurai warrior caste and the _bakufu_ (government center of the shogun) of the Kamakura period (1192-1333), the _Golden Age of Ninjutsu_ began, which lasted for over 400 years. During this period between 25 and 70 different _ryū_ (schools) arose, mainly in the Iga and Kōga provinces. During the same period, Zen Buddhism, the basic philosophy for the Samurai caste, was introduced to Japan.
+
+The Hattori and Oe clans ruled the Iga province, while the Kōga province was ruled by more than 50 families.
+
+
+
+In the 14th century Japan was shaken by bitter fighting. In 1392 Japan was united under one emperor. But just 75 years later, unrest broke out again. The local rulers, Daimyō, men whose clans had grown in power and influence over the centuries, had taken control of Japan and the shogun was reduced to a powerless puppet.
+
+The Daimyō fought bitterly for 400 years until the general, Toyotomi Hideyoshi, finally succeeded in reuniting Japan in 1590. This circumstance led to the fact that Ninja were needed everywhere. Therefore, more and more Ninja schools were opened to meet the tremendous demand.
+
+## Firearms and Espionage
+
+The first firearms (matchguns from Portugal) were brought to Japan by merchants in 1543. Among the Samurai, the use of _teppō_ (arquebus) was considered dishonorable and this task was incumbent on the lowly _ashigaru_ (foot soldiers, mostly peasants).
+
+The Ninja had no compunction about the use of firearms, and with the advent of firearms, they simply incorporated them into their arsenal. From then on, wooden cannons, bronze pistols and anti-personnel mines were part of their arsenal.
+
+Many generals hired Ninja to spy on their rivals. Two of these were Takeda Shingen and his rival Uesugi Kenshin. Takeda’s spies used beacons to deliver their messages, while Uesugi’s Ninja were often disguised as itinerant doctors. Tokugawa Ieyasu, the famous general, also often resorted to Iga and Kōga Ninja.
+
+## Ninja Provinces and Their Rulers
+
+The Kōga province was ruled by more than 50 different Ninja clans, while the Iga province was divided into three ancient families: the Hattori, the Momochi and the Fujibayashi.
+
+The Momochi clan ruled the southern part of the province, the Hattori ruled the center, and the Fujibayashi clan ruled the northern part of the province. In addition, the Fujibayashi could still fall back on Ninja of the Kōga province.
+
+Their supreme leaders were Momochi Sandayu, Hattori Hanzo, and Fujibayashi Nagato, all three of whom lived in the 16th century.
+
+In order to confuse his enemies and to clarify his identity, Sandayu had three different houses, each with a wife and children.
+
+If an area became too dangerous for him, he simply changed his place of residence and his identity.

+When the political and economic conditions became more unstable in the 14th century, many new Ryū were founded. Families were forced to swim against the tide when creative thinking and original action were the last resorts to ensure survival. Other Ryū were merely activated temporarily to aid a particular warlord, military force, or religious order in a specific matter. When these Ryū had fulfilled their task, they were dissolved again. Some styles tended to be localized, aligning with other Ninjutsu schools in that area for geopolitical reasons. Still others relied solely on the experience, knowledge, and wisdom accumulated by the clan’s founder during his lifetime.
+
+The historically attested Japanese Ninjutsu Ryū varied greatly in size and importance. There were very small clans made up of a few family members and others made up of hundreds of Ninja.
+
+## List of Main Schools
+
+The following list includes some of the historically most important Ninjutsu Ryū, along with their leaders, areas of operation, and military and political affiliations:
+
+- The **Nakagawa-Ryū** had its operational area in the Aomori district. It was organized by Nakagawa Kohayato.
+- The **Haguro-Ryū** had its heartland in the Yamagata district. It is said to have been developed by the warlike ascetics of Mount Haguro.
+- The **Uesugi-Ryū** was developed by Usami Suruganokami Sadayuki (Niigata District) for Uesugi Kenshin as a military espionage organization.
+- The **Kaji-Ryū** was founded by Kaji Ominokami Kagehide, a disciple of the founder of the Uesugi-Ryū, but he also had connections to the fathers of the Hattori-Ryū (Iga province).
+- The **Matsumoto-Ryū** operated in the Tochigi district.
+- The **Matsuda Ryū** operated in the province of Ibazaki.
+- The **Koyo-Ryū**, **Ninko-Ryū** and **Takeda-Ryū** were founded by Takeda Shingen to work as agents. These Ryū made extensive use of spies disguised as wandering monks or traders.
+- The **Fuma Ninpo** (Kanagawa District) was founded by Fuma Kotaro and specialized in guerrilla warfare.
+- The **Akiba-Ryū** and **Ichizen-Ryū** (Aichi District) were founded by Hachisuka Koroku Masakatsu, a famous warrior of the area.
+- The **Mino-Ryū** (Gifu district) was developed during the reign of Saito Dosan and included the Kurokawa Ninja group of the Kōga area.
+- The **Echizen-Ryū** (Toyama district) was founded by Iga Ninja who managed to flee from Oda Nobunaga’s troops.
+- The **Yoshitsune-Ryū** (Fukui District) was developed by Minamoto Yoshitsune. This Ryū was a mixture of Ise Saburo’s espionage methods and various _yamabushi_ teachings.
+- The **Kōga-Ryū** was a regional Ninjutsu tradition made up of more than fifty families.
+- The **Iga-Ryū** was also a regional Ninjutsu tradition composed of several important families, e.g. the Hattori and Momochi clans.
+- The **Negoro-Ryū** was founded by Suginobo Myosan, a firearms specialist. The **Saiga-Ryū** trained firearms and explosives specialists to become Specialists. The **Natori-Ryū** was founded by Natori Sanjuro Masatake, the author of the Shoninki Ninjutsu Reference Book. These Ryū, along with **Kishu-Ryū** Ninjutsu, had their ancestral home in Wakayama County.
+- The **Bizen-Ryū** came from the Okayama district.
+- The **Fukushima-Ryū** (District Shimane) was developed by Nojirijiro Jirouemon Narimasa.
+- The **Kuroda-Ryū** (Fukuoka District) supported the Kuroda ruling family.
+- The **Nanban-Ryū** operated in the Nagasaki district.
+- The **Satsuma Ninpo** (Kagoshima District) supported the Shimazu ruling family.
+
+Except for a few, these Ryū had become extinct long before the beginning of the Meji Era in 1868.

+excerpt: "The Ninja strove all his life to follow the ‘path of the warrior’ to enlightenment. Enlightenment is an elusive concept that represents a state of perfect understanding and clarity."

+ - religion
+ - training

+
+## The Path to Truth
+
+Although we are no more than a brief spark in the eternal course of the universe, each of us has a part of a greater truth to recognize and cope with. This does not mean that everyone has to come to the same insight. Each of us has a different question, and one answer will by no means give everyone the same satisfaction.
+
+There are countless paths one can take, and on each, it is possible to attain satori (enlightenment) and insight. One person may choose the path of knowledge and perhaps become a scientist, another the path of healing and become a doctor or nurse, a third choose the path of rule and become a politician or found his own company. Or you could also go the way of the servant or the way of the merchant.
+
+There are numerous other ways, this is just a small selection that you can make. And there is the way of the warrior that we _bujin_ have taken as our way.
+
+## The Choice of Path
+
+The first and most difficult step on the path of life is to find and tread the path that is right for us. In the past, it was customary to take the path that birth had preordained. But today you have the freedom to choose your path. However, this freedom can also be confusing, and the number of possible paths can confuse a person. Some discover their path in their youth and follow it undeterred until death. Others discover their way later, some never discover the right way. Others change their path several times until they find fulfillment.
+
+Each of us may find a different answer on our way, but all ways have one thing in common: They only serve as a means to an end and must never become an end in itself.
+
+## The Path of the Warrior
+
+Those who have chosen the path of the warrior may come to the realization that all conflict is futile and they work on their strength and invulnerability that gives one the freedom to choose love and generosity.
+
+In many cases, a warrior on the path to enlightenment will at some point embark on an odyssey – _musha shūgyō_. This odyssey robs the warrior of his homeland, comfort, an orderly daily routine, friends, family, or his mother tongue. The Ninja must be adaptable and resourceful to handle this situation.
+
+Various factors make it difficult for the warrior to enter and follow the path to enlightenment. What hampers us most is that the warrior’s path requires one to immerse oneself in only one aspect of existence and to follow that path with zeal every day of one’s life.
+
+A person who practices martial arts as a hobby is by no means following the warrior’s path. The warrior’s path is an everlasting, lifelong, all-consuming commitment to be followed without deviation.
+
+## So What is Enlightenment?
+
+The word _enlightenment_ is handy and yet not easy to define. But enlightenment cannot be put into words, but when it begins to bloom in you, you will recognize it for yourself.
+
+The key to enlightenment lies in letting go of the ambitious pursuit of recognition and losing yourself in an all-encompassing activity or situation.
+
+Enlightenment does not have to be instantaneous, in very few cases does it happen suddenly. Rather, enlightenment can grow slowly. This sense of selflessness can be achieved through a glorious setting, through a meaningful event, or through the shedding of all constraints.
+
+In that moment of truth, one feels awe, joy, total oneness, and vitality.
+
+Such an event brings with it a different way of thinking, and this gives rise to different insights that can fundamentally change the way we live and act. All oppressive heaviness can disappear from our lives.
+
+Enlightenment for the warrior is the realization that everything is just an illusion and that anything or situation, no matter how _good_ or _bad_ it is judged, is seen by the universe as _right_ and _right_.
+
+## Achieving Enlightenment
+
+One method of achieving enlightenment is to break free from all limiting attachments. These bindings can be denoted symbolically as _name_, _elements_, and _emptiness_.
+
+The first influence, the **Name** includes everything you have done or been done to you up to that point. All the things you felt powerless to do. Everything physical, social, familial, and genetic that you’ve carried around with you since birth. But all talents and abilities that one has acquired over time, yes, the entire body and all tendencies belong to this category.
+
+Getting rid of these elements means removing every weakness you thought you had to live with. It means eliminating all subterfuges and self-limiting habits that one normally used for convenience.
I’m just fat
,
I don’t grow muscles
,
I’ll never learn that anyway
, etc. are no longer there from that point on.
+
+This is far more difficult than it appears at first glance.
+
+The second influence, the **Elements**, involves the manner in which one responds to incidents. This includes friends and enemies, strengths and weaknesses that you have acquired over time. All cultural, political, and economic influences also belong in this category.
+
+Eliminating these elements means throwing out all standard methods, prejudices, ideals, and blocking opinions. So you have to rethink your current understanding of life. This is very difficult and requires a great deal of patience and perseverance.
+
+The third influence to reckon with is the **emptiness**. This influence includes one’s potential and power to shape and direct one’s life. One must give up the futile project of basing all actions, plans, and interactions on purely rational and mechanical principles.
+
+One must be able to interpret the cosmic signs, otherwise one will wage a hopeless struggle for the rest of one’s life. But you can also fall into total helplessness because you’ve been waiting your whole life for a little bit from heaven, for helping spirits to save you.
+
+No matter how many books or life guides you read, if you don’t root your goal deep down, enlightenment cannot be achieved.

+
+## Takamatsu Toshitsugu
+
+> The essence of all martial arts and military strategy is self-protection and avoidance of danger.
+>
+> Ninjutsu presents itself as the fullest concept of self-protection through war training, because the art of the Ninja protects not only the body but also the mind.
+>
+> The way of the Ninja is the way of enduring, of surviving, and of victorious over anything that wants to destroy you.
+>
+> This is more than just dealing punches and slashes, and deeper than simply outwitting the enemy; Ninjutsu is the way to really get what you need while making this world a better place.
+>
+> The Ninja’s skill is the art of winning. Proper motivation is crucial at the start of training. Without the right state of mind, continued use of martial arts can lead to annihilation rather than self-development.
+>
+> But this fact is not very different from other useful practices in life taken to extremes.
+>
+> Medical science is designed for the improvement of health and the relief of distress, and yet the abuse of drugs and the triumph of physicians mean that personal health is no longer in one’s control.
+>
+> A nutritious, balanced diet is designed to keep a person alive, strong, and healthy, but grossly overeating or overdrinking, or ingesting too many chemicals is the surest way to poison the body.
+>
+> Governments are created to oversee the harmonious working of all parts of a society, but when the rulers are greedy, power-hungry, or lacking in wisdom, useless wars, disorder, or cultural and economic chaos result.
+>
+> A religion based on trust through experience, a broad aspiring mind and tireless pursuit of universal understanding brings people inspiration and comfort. Once a religion has lost its original basis, it becomes a deadly thing that deceives, controls and burdens people by manipulating beliefs and fears.
+>
+> It’s the same with the martial arts. The art of self-protection, intended to create a sense of inner peace and security, is so often developed without a balance of personality, and leads the lesser martial artist into warped worlds of ceaseless conflict and competition that eventually consume him.
+>
+> When a martial arts expert sincerely follows the essence of Ninjutsu, free from the influence of egoistic desires, the student will realize the ultimate secret of invulnerability – attaining the _Mind and Eyes of God_.

+> The great cosmos, beautiful in its cool, impersonal totality, contains all that we call good and evil, all the answers to all the contradictions we see around us.

+>
+> The methods of physical and mental survival immortalized by Japan’s Ninja were in fact the source of all Japanese martial arts.

+> Without full and holistic training in all aspects of the martial arts, today’s martial artists cannot hope to achieve more than simply experiencing the limitations of their muscular capabilities for their own training.
+>
+> Personal enlightenment can only be achieved through a total immersion in the traditions of martial arts as a way of life.
+>
+> By experiencing the confrontation with danger, the superiority of fear, injury, or death, and the workings of one’s powers and limitations, the practitioner can attain the strength and invincibility that allow him to enjoy flowers that sway in the wind, of appreciation the love of others and contentment with the peace in society.
+>
+> The attainment of this enlightenment is characterized by the development of _jihi no kokoro_ or a _kind heart_.
+>
+> Stronger than love itself, the _kind heart_ is able to embrace all that employs universal justice and all that finds expression in discovering the universal plan. Born to achieve understanding, by repeatedly striding on the edge between life and death, the ninpō’s kind heart is key to achieving harmony and understanding between the two.
+>
+> Forgotten in the shadows of the past after so many generations, the Ninja philosophy of life reappears, because once again a time has dawned in human destiny that ninpō needs. May peace prevail so that humanity can grow again to the next, higher level.

+
+## The Hattori Family
+
+One of the most famous families in Iga was without a doubt the Hattori family. They descended both from Otomo Hososto, a high member of one of the most important families in Japan, and from China. The Otomo family were employed in the service of the imperial family primarily for their knowledge of warfare. The sons of the Hattori were later allowed to create their own branches of the family.
+
+According to some sources, it was Iga Heinazae Mon no Jo Ienaga who gave the eldest son Hattori Hei Taro Koreyuki the right to use the family name Kamihattori. Middle son Hattori Heijiro Yasuyori founded the Nakahattori surname and youngest son Hattori Heijiro Yasunori founded the Shimohattori surname.
+
+Each family had its own _mon_ (family crest), the Kamihattori had **yahazu-nihon** (two arrowheads) on their _mon_, the Nakahattori **ichitomoe** (a bow) and the Shimohattori **yaguruma** (eight arrowheads in a ring).
+
+That each family had its own _mon_ indicates that they were of the same rank as a Samurai. According to modern history books, Hattori Hanzo is said to have been a Samurai from Iga. When Oda Nobunaga conquered Iga, only 80 individuals from the three Hattori families survived. They fled to different parts of Japan.
+
+The Kamihattori fled to the village of Nagaoka in Echigo. The Shimohattori received protection from the Tokugawa family in Mikawa or from the Ochi family in Takatori Village in Yamato Province. The Nakahattori fled up into the Takano Mountains.
+
+## Hattori Hanzo
+
+The most famous Ninja in history was without a doubt Hattori Hanzo Masahige (1541-1596). He was the son of Hattori Nazo Yasunaga, who had become a vassal of the Tokugawa family through marriage. The Tokugawa were known as Matsudaira during this period. They belonged to the Kamihattori branch of the family, but whether they descended from the Heitaro or the Chigachi is unknown.
+
+{% figure "A portrait of Hattori Masanari aka Hattori Hanzo from the 17th century." %}
+
+
+
+{% endfigure %}
+
+Hattori Hanzo grew up with martial arts and it became his main occupation in his life. In 1557, when Hattori Hanzo was sixteen years old, he fought in battle for the first time in his life. It was the night that Tokugawa Ieyasu attacked Uzuchijo in Migawa (the castle in Udo). Here he received his first reward for his outstanding performance on the battlefield. He was nicknamed _Hanzo the Ghost_, and even the Tokugawa recognized his abilities. After that he was involved in the Battle of Anagawa in 1570 and the Battle of **Mikata Ga Hara** in 1572. Due to his abilities, another nickname was also _Hanzo the Devil_.
+
+The Hattori family were not _watari_ Ninja (Ninja who sold their services for the highest bidder), they were staunch followers of the Tokugawa. When Oda Nobunaga was assassinated by Akechi Mitsuhide, Tokugawa was in a village near Osaka and was attacked by Akechi’s troops. Tokugawa was assisted by Hattori Hanzo and Taro Shiro, a Kōga Ninja. Along with 300 Ninja, they helped Tokugawa escape to Okazakijo, using _goton jutsu_ and other special techniques to reach their destination undisturbed.
+
+Hattori Hanzo’s many merits gave him great prestige and he was appointed leader over the Hassenshi Samurai. On December 4, 1596, Hattori Hanzo died while leading a force to attack Fuma Ryū Ninja from Kanagawa. Hanzo and his troops had followed the Fuma Ryū Ninja out to sea in boats, but the Fuma Ryū Ninja used underwater techniques to destroy their oar. As Hanzo and his men jumped into the water to swim to shore, the Fuma Ryū Ninja set fire to the oil they had poured into the water. All perished in the flames. Hattori Iwami no Kami Masanari later achieved success where Hattori Hanzo had died.
+
+The people of Japan still sing songs in the Kawauchi area. He is known there as _the great lancer_, a very strong warrior. Not many know of his connections to Ninjutsu, rather he is known as _bushi_ (warrior) from _Iga_.
+
+## The Two Identities of Momochi Sandayu
+
+Besides the Hattori family, the Momochi and Fujibayashi were the most famous Ninja families of the Iga province. Some sources claim they are descended from Otomo Hososto and the Otomo family. It is reported that the Momochi controlled southern Iga, the Hattori controlled central Iga, and the Fujibayashi controlled northern Iga. Momochi Sandayu was the most famous Ninja leader along with Hattori Hanzo.
+
+Momochi Sandayu was the grand master of Momochi-Ryū and Gyokko-Ryū under Tembunera (1542-1555). He was also known to be a skilled Ninja.
+
+To hide his identity he had three different houses, one was in Ryugu Sanbonmatsu in Yamato Province and was built by the Daimyō Kitabatake Tomonori. The others in Hojiro Yamato and Takiguchijo. He also had three different families that he switched between. The place where he mainly resided in the 1570s seems to have been Ryugu Sanbonmatsu after he was considered to be made a leading man in the village.
+
+Many sources report that Momochi Sandayu and Fujibayashi Nagato were **one and the same person**. There is a reason why he is not mentioned in any source when Oda Nobunaga conquered Iga in 1581, but heroic deeds are narrated by Momochi.
+
+One of Momochi Sandayu’s houses in Takiguchijo, near Iga Ueno, was burned down by Oda Nobunaga after the invasion of Iga, but Momochi managed to escape with his men and he stayed in Sanbonmatsu until news of Oda Nobunaga’s murder broke on June 10, 1582 experienced. Probably Sandayu Momochi died not long after the invasion, his grave was found in 1960 in the old family cemetery near the village of Nabari on Mount Okaone, about 24 kilometers from Iga Ueno. It was found on a hill near one of his houses.
+
+{% banner "Momochi Sandayu’s Double Life" %}
+
+In the film
Shinobi no Mono one can see the double life of Momochi Sandayu filmed, as he switches back and forth between the two houses and competes with himself.
+
+{% endbanner %}
+
+Momochi Sandayu II inherited both the Gyokko-Ryū and Koto-Ryū in the Tensho period (1570-1592) from Momochi Sandayu. Who became the next _soke_ (head of a Ryū) of the Momochi-Ryū is unknown. The Gyokko-Ryū and Koto-Ryū were passed on to Momochi Tanba Yasumitsu in the Bunroku period (1596-1615). He was also known as Tanba no Kaimi and Lord of Ryugu Castle. Momochi Taro Daemon, who was the lord of Shokudai Castle in Ueno, took over the seat of the clans in the Genna period (1615-1624). After that, the two Ryū left the Momochi family and went other ways in the Iga province.
+
+## Other Famous Ninja
+
+Other prominent members of the Momochi family were Momochi Jindayu Yasumatsu, Momochi Sannojo, and Momochi Chuzuburo Yasumatsu, among many others. That the methods were very effective was proven by a _kunoichi_ named Tanaka Sadako who was never exposed when she went into hiding.
+
+Descendants of Momochi Sandayu still live in one of his houses, however they no longer have any connection to the Momochi Sandayu Ninja tradition. All remaining Ninja tools were sold to museums and collectors two or three generations ago.
+
+Not much is known about the Fujibayashi family. What is known is the fact that Fujibayashi Nagato and Momochi were actually one and the same person.
+
+If the Fujibayashi family did not exist as a Ninja family, it is still possible that the author of the Bansenshūkai, Fujibayashi Yasutake, belonged to the Ninja family or, through being related to them, was able to gain enough knowledge to write the books.
+
+It is also said that the Fujibayashi controlled their clan from the castles in Yubano and Ayama.

+
+## School of Learning Justice
+
+The Gikan-Ryū _koppō jutsu_ was founded by Uryu Hangan Gikanbo, who was Daimyō of Kawachi no Kuni (Kawachi Castle). It is narrated that Uryu Hangan Gikanbo’s blow was so powerful that he once broke a sword blade in half.
+
+Takamatsu Toshitsugu originally assigned the Ryū to Akimoto Fumio, who became the 14th _sōke_. However, Akimoto died prematurely from illness in 1962 and he had no heirs. So the system came back to Takamatsu Sensei. He then assigned it to Hatsumi Masaaki, who is the current _sōke_.
+
+A teaching of the Gikan-Ryū is
武風に先手なし
(
The first blow does not come from this side
). The Ryū has many special kicks, punches, and throws. Hatsumi has stated that the Ryū has no step-by-step explanations of the techniques and no _kata_. That is why the methods are passed on orally.
+
+Hatsumi has not yet taught this Ryū in public because it is said to be very difficult. The stances should be very deep, with the toes almost always pointing in the opposite direction, which requires good balance.

+excerpt: "The Godai is a philosophical view of the universe. By understanding the workings of the five elements and their manifestations, the Ninja tried to understand the connections between creation and thereby himself."
+translationKey: "godaiPage"
+categories:
+ - philosophy
+---
+
+## Development of a Natural Consciousness
+
+The Ninja aimed to develop _kiai_ consciousness, i. H. they wanted to become _through and through natural beings_. For this one must experience the working of the cosmic laws or the universal consciousness directly on oneself. To do this, one must observe nature with an open mind and understand one’s own connection to all things. This leads to self-awareness.
+
+For this they used two different systems of contemplation of nature – the _godai_ and the _gogyō_.
+
+## Five Elemental Manifestations
+
+The _godai_ derives from the _mikkyō_ and teaches that all physical aspects come from one source and can be assigned to one of the five primary elemental manifestations:
+
+- **Ku (Emptiness)** or the origin of subatomic energy, the nothingness, the beginning of all things
+- **Fu (Wind)** or the gaseous elements
+- **Ka (Fire)** or the energy-giving elements
+- **Sui (Water)** or the liquid elements
+- **Chi (Earth)** or the solid elements
+
+## The Creation of the Universe
+
+To understand the principle better one can e.g. consider the creation of the universe in this way.
+
+In the emptiness (_ku_) polarity and electromagnetic charges arose. From this came the atoms and electrons and thus the various gases (_fu_). When these gases reacted with each other, it was on the energy-yielding plane (_ka_). The resulting molecules became vapor (_sui_). Eventually solid matter (_chi_) emerged from this.
+
+This example is of course a very simplistic representation of creation, but it can be used for understanding. Concerning humans, the bones, teeth, muscles and eyes would represent solid matter. The bodily fluids liquid matter, body heat and combustion would represent the fire and respiration would represent the air. The emptiness would show up in the ability to speak and communicate.
+
+## Earth
+
+Human consciousness can also switch back and forth between these levels. When consciousness is at the earth level, one is aware of one’s own stability. There is resistance to change and movement, and one wishes for things to remain as they are. Rocks are a good example of this level. They don’t move, don’t grow, and don’t change without action. The earth is assigned the color red and is located at the base of the spine. A fighter at this level is unperturbed, has a stable stance, and withstands any attack. It’s like fighting a boulder.
+
+## Water
+
+When consciousness is at the water level, one is aware of one’s feelings and bodily fluids. Adaptation and response are characteristics of this stage. One reacts to all events and has gloomy feelings. The best example of this level are plants. They grow and adapt to environmental conditions, but cannot dominate their environment. The color associated with the water element is orange. The seat is the _hara_, the lower abdominal cavity. A fighter at this level is always on the move, dodging and making sudden, unexpected moves. One has the impression of fighting against the waves. They retreat and strike again.
+
+## Fire
+
+At the fire level of consciousness, one is aware of its dynamic, expansive nature. One has feelings of joy and warmth and strives to subjugate the environment. You are aware of your mental and physical potential. A good example of this level are wild animals. They can remember, they can think, they seek pleasure and joy. The color yellow is assigned to this element. The seat of this element is in the solar plexus, at the lower tip of the breastbone. A fighter at this level fights with fierce determination. He fights hard and fiercely. It’s like fighting a brush fire, the harder you hit the flames the harder it burns.
+
+## Air
+
+When one is at the level of consciousness of air one feels wisdom and love. One recognizes his intellect and his benevolence. One feels compassion and understanding for others. The color assigned to this element is green. The center of the chest is considered to be the seat of the element. A fighter at this level fights defensively. He protects himself, but does not deal much damage to the opponent. He intercepts attacks and redirects energies. It’s like fighting against the wind. He dances around you without being able to catch him.
+
+## Emptiness
+
+The emptiness level of consciousness brings about creativity and the ability to shift from any level to the other. The color blue is assigned to this element. The neck is considered its seat. There is no struggle at this level. Thoughts, words and deeds create a situation where a fight doesn’t even happen.
+
+## The Elements in Daily Life
+
+Each of these levels of consciousness can appear both negatively and positively. With earth the positive effect could be stability, the negative self-destructive stubbornness, with water the positive effect could be flexibility, the negative sentimentalism. A possible positive effect of fire could be aggressive vitality, a negative overwhelming fear. With the wind, a positive effect could be wisdom and love, a negative effect spirituality that conceals the truth.
+
+Whether it’s dealing with fear, joy, boredom, what movies you love, what drives you, how you handle arguments, or what advice you give, all of these factors fall into one of the most elementary levels. Most people are in a transition between levels, but some have also settled on a level. One cannot speak of _good_ or _bad_ here, everything is correct and adjusted because everything is a part of the universe. In this way one can understand what motives a person has or what problems torment him.

+excerpt: "The Gogyō is a Daoist element system based on the polarity theory of yin and yang. This model is intended to show how all elements are linked, create or destroy themselves."
+translationKey: "gogyoPage"

+---
+
+## The Theory of the Five Elements
+
+The _gogyō_ comes from the Taoist teachings of China. Unlike the _godai_ system, where each appearance can be assigned a fixed plane, the _gogyō_ taps into the polarity theory of yin and yang (_in_ and _yō_ in Japanese) and seeks to establish the cycles of transformation that continually take place on the material plane. Five code designations were developed for this, but they should only be regarded as a code and not as a literal classification.
+
+- **Sui (Water)** or dissolving
+- **Moku (Wood)** or growing
+- **Ka (Fire)** or evaporating
+- **Do (Earth)** or condensing
+- **Kin (Metal)** or hardening
+
+In ancient China, everything was subject to an eternal cycle, the seasons, the days, and the processes in the body. A man was not seen as an isolated being, but as his own little universe, a microcosm in the macrocosm, so to speak. Every aspect of Chinese culture, whether it be politics, medicine, art, or martial arts, could elude this theory. Therefore, different organs, points of the compass, colors, seasons, or animals were assigned to the five elements.

+
+There is a hierarchy among the elements that in one possible order brings forth each other, in a different order each element destroys or subdues another. In the opposite order, one element overwhelms the other. Thus, wood produces fire, fire produces earth (as ash), the earth produces metal (ores), metal produces water (condensation on the surface), and finally, water produces wood (plants).
+
+The wood conquers the earth like a plow, the earth tames the water like a dam, the water quenches the fire, the fire melts the metal and finally, the metal cuts down the wood like an ax or a saw.

+The elements are difficult to separate from each other and, of course, there are usually several elements to be found at the same time. When climbing rocks (_doton_), metal climbing tools (_kinton_) were of course also used. When hiding in burrows (_doton_) or water (_suiton_), vegetation (_mokuton_) was often added for camouflage. These categories can also be expanded at will, and modern technologies such as GPS also fit into one of these categories.

+
+## School of the Jeweled Tiger
+
+The Gyokko-Ryū _koshi jutsu_ is the oldest of the nine warrior traditions of the Bujinkan, and it can be said without question to be the core of most of our arts. Hatsumi Sensei established that _koshi jutsu_ forms the basis for the following systems: Togakure-Ryū, Koto-Ryū, Gikan-Ryū, Shinden-fudo-Ryū, Gyokushin-Ryū, and Kumogakure-Ryū. Gyokko means
bejeweled tiger
or tiger jewel and can refer to the tiger’s eye.
+
+The method of movement and basic principles were developed in China during the Tang Dynasty (618-907). One suspects from the movements that it was developed by either a small man or a small woman. It is known that there was a woman at the court in Chan’an (now Xi’an) who was well known for her martial arts. When the Tang Dynasty was overthrown in 907, many of the nobles fled to Japan. The names Yo Gyokko (Yao Yu Hu) and Cho Gyokko are associated with the arrival of martial arts in Japan (perhaps they were the same person). General Ikai (or Ibou) is also associated with the origin of Gyokko Ryū. According to Hatsumi, this person could also be someone (bou) from a foreign country (I).
+
+The first real _sōke_ of the _official_ Gyokko-Ryū was Tozawa Hakuunsai. His name may mean a connection with the Hakuun Ryū Ninjutsu, which no longer exists. This all took place in the Hogen Era (1156-1159), making Gyokko-Ryū the oldest documented fighting system in Japan.
+
+_Koshi jutsu_ means _to knock down the tiger with one finger_. That is why there is strong punching training, especially for the fingers, toes, and knuckles, but also for all other parts of the body. Characteristic of the fighting style is powerful blocks with the knuckles that destroy the attacker’s muscles, tearing and drilling techniques with fingers and toes, powerful stomping kicks, grappling techniques, and throws. In the Gyokko-Ryū it was taught to use only as much force as was necessary to defeat the opponent. In addition, the Ryū was known for his skills with the sword, for _roku shaku bō_ and _tantō_.
+
+## The Nine Rules of Gyokko-Ryū
+
+- The sign _nin_ means to protect the nation, even with your life.
+- Forget yourself. Be patient and do not fear death.
+- In dangerous situations, say nothing and show nothing.
+- When a strong enemy appears, keep an indomitable spirit.
+- Serve and protect the master, just like your parents.
+- Crime dissipates your skills.
+- Drunkenness impairs your judgment.
+- Destroy the opponent’s power, but leave him his life.
+- Do not teach others without Master’s permission.

+
+## The School of the Jeweled Heart
+
+Gyokushin-Ryū Ninjutsu is a branch of _koshi jutsu_ and is believed to have been founded by Sasaki Goeman Teruyoshi, a student of Gyokko-Ryū. The methods of Kumogakure-Ryū (blocks, punches, and stances) are very similar to those of Gyokko-Ryū.
+
+Sasaki Gendayu was in the service of the Daimyō of Kishu and received a salary of 200 _kokū_ (Japanese capacity for rice, one _kokū_ equals about 180 liters of rice) per year, later even 400 _kokū_. Like his father, he was probably very capable of Gyokko-Ryū.
+
+The Gyokushin-Ryū was taught in secret, in the Kishu and Takeda provinces. Sometime in the 17th century, he came into contact with the Togakure-Ryū and the Toda family. After the style was passed down to Toda Nobutsuna, it was no longer kept secret.
+
+Little is known about the combat system of the Gyokushin-Ryū. The system was more focused on espionage and other Ninja skills than combat.
+
+The Gyokushin-Ryū is known for its use of the _nagenawa_ (lasso).
+
+Kano Jigoro, the founder of judo, was a friend of Takamatsu Sensei. It is believed that Takamatsu taught Gyokushin-Ryū as a guest at the Kodokan.

+ - biography
+---
+
+## Birth
+
+Dr. Hatsumi Masaaki was born Hatsumi Yoshiaki on December 2, 1931, in Noda, Chiba Province. He later changed his name to Masaaki. Other names of Hatsumi are Toratsugu, Tetzusan and Hisamune. At the age of 7, Hatsumi learned kendo from his father. He also trained in Aikidō, Jūdō, and Karate. At school, Hatsumi practiced gymnastics and boxing and was captain of the soccer team. He practiced dancing, which helped him learn Budō. In high school, he continued boxing and engaged in judo. He studied dramaturgy and theater studies.
+
+## Theater Studies and Osteopathy
+
+Hatsumi received his degree in drama and osteopathy from Meiji University in Tokyo. He then set up a practice for osteopathy. While at university he achieved 4th _dan_ in jūdō, which was rare at his age.
+
+## Jūdō Training With Americans
+
+{% figure "Hatsumi Masaaki" %}
+
+
+
+{% endfigure %}
+
+He was asked if he could practice judo with the American soldiers at Yokote Army Base. Americans, being taller and stronger, mastered judo in a matter of months, which would take a Japanese man many years of hard practice. Hatsumi doubted the effectiveness of judo when one could not win against larger, stronger opponents as a smaller or weaker fighter.
+
+He began to search for real martial arts and practiced _kōbujutsu juhappan_ with Ueno Sensei. After three years he had mastered the style and his teacher said there was nothing more he could teach him. He advised Hatsumi to go to Nara and find a capable teacher.
+
+## Meeting With Takamatsu
+
+{% figure "Hatsumi Masaaki" %}
+
+
+
+{% endfigure %}
+
+When Hatsumi was 26 years old, he met Takamatsu Toshitsugu, who was nicknamed Moko no Tora (Mongolian Tiger).
+
+In _taijutsu_ you can use movement and distance to defeat a physically superior opponent.
+
+From then on, Hatsumi traveled ten hours a week for 15 years to his master via the island of Honshū. He left Noda on Friday night, staying with his master and training with him over the weekend. On Sunday night he left again and made the long journey back to open his practice again on Monday morning.
+
+After passing the _sakki_ test, Takamatsu gave him the _menkyōkaiden_ of the 9 Warriors Ryūha.
+
+## Hatsumi’s Sakki Test
+
+Hatsumi reports that one day his master asked him to sit down and close his eyes. Then he left the room. After several hours, Hatsumi felt a heavy pushing force from behind and pictured a body split in two in his mind’s eye. Intuitively, Hatsumi performed a sideways roll. At that moment he heard his teacher say
Well done, you did it, you can now open your eyes
. The master had approached silently from behind with a sharp sword and executed a swipe.
+
+## Takamatsu’s Death
+
+A year later, Takamatsu Sensei died. Before that, he told Hatsumi that he taught him everything he knew, thus repaying his masters for their kindness.
+
+He decided that Hatsumi was the most capable of his students and should therefore carry on the legacy. Hatsumi became the new _sōke_.
+
+## Founding of the Bujinkan
+
+{% figure "Hatsumi Masaaki" %}
+
+
+
+{% endfigure %}
+
+He named the _honbu_ Dōjō Bujinkan Dōjō in honor of his teacher. The dojo has been at his house. More recently he has built a new dojo and now lives in a house in the country.
+
+At the age of 30, he married his wife Mariko.
+
+## Seminars Worldwide
+
+Hatsumi traveled around the world several times a year, holding seminars and _taikai_ (Big Gathering, Ninja Events). Due to his old age and to take care of his wife, Hatsumi now only stays in Japan. However, he still trains occasionally in the _honbu_ Dōjō (main training hall in Tōkyō).
+
+## Awards and Honorary Degrees
+
+He has received numerous military and public awards worldwide. He received two more doctorates, one in philosophy and one in science.
+
+1986 was awarded the Black Belt’s Instructor Of The Year Award.
+
+He is a scientist, painter, actor, musician, singer, and author who has written countless columns in newspapers and magazines has written many books on Ninjutsu and published the Bujinkan magazine _sanmyaku_ (mountain range).
+
+{% figure "Hatsumi Masaaki with the actors from Jiraya" %}
+
+
+
+{% endfigure %}
+
+He has shot more than 25 videos and participated in many films: **Shinobi no Mono**, **You live only twice** (James Bond), 50 episodes of the popular children’s series **Jiraya** and **Suteki no Mummy**.
+
+He is considered a national treasure in Japan and is one of the most important martial artists in the world.
+
+Because of the unbelievable complexity of the schools, he decided not to train them separately, but to train them as a unit.
+
+Training under Hatsumi is said to have been very hard at first, but in 1988, at the beginning of the Heisei period (Heisei means _to become peaceful_), he decided to adapt the Bujinkan to this aspect and toned down the training.
+
+Since 1995 the martial art in Bujinkan has been uniformly called **Budō Taijutsu**.

+---
+
+## Infiltration of Enemy Lines
+
+If a Ninja wanted to break through enemy lines to get to his area of operations, he had to be resourceful.
+
+A tactic was often used in which a squad of Ninja or Samurai carried out a mock attack (_ennyu no jutsu_). If all the troops rushed to attack, the Ninja could get into the fortress unhindered. Sometimes the Ninja disguised himself as a simple foot soldier. These were mostly recruited from farmers and nobody knew their identity, so the Ninja could move around unmolested.
+
+Sometimes a troop of Ninja was also with the enemy as mercenaries and so came unhindered into the area of operation. When building the castle of Iga, the Ninja mingled with the workers and were able to find out the weak points of the fortress, which later helped them to victory.
+
+## Strategies for an Infiltration
+
+To get into the enemy castle or camp, the Ninja used different strategies.
+
+First, he had to wait for the right time to attack (_nyukyo no jutsu_, Eng.
the art of invasion
). A favorable time for an attack was when the enemy force had left the camp for a campaign. He climbed over the ramparts and opened the gates to his troops. Another possibility arose when a camp had only been set up a few days or when new troops had arrived. At that point, everything was not properly organized and it was easy to disappear.
+
+The Ninja used cooking and mealtimes, horse feeding times, and rest times to gain access.
+
+The night after a celebration, after an accident or death, or after a sick person has recovered is particularly suitable. Even after winning and losing battles, it was easy to get to the camp.
+
+He liked to use the weather – in rain, snow, storms, and on moonless nights he attacked his enemies.
+
+Sleeping habits were also included in the planning. Lieber was attacked in spring and summer because people sleep more deeply at that time. In the fall and winter, most people don’t sleep that deeply, so he avoided that time.
+
+He knew that older people need less sleep, that fat people usually sleep well and thin people badly.
+
+Then he found out the weaknesses of the enemy’s defenses (_monomi no jutsu_). He preferred rooms that were easier to break into. These were usually rooms far from the kitchen, dining room, or pantry. He looked for back doors or unused rooms, like guest rooms.
+
+## Man as a Weak Point
+
+But he also made use of the weaknesses in human defenses (_nyudaki no jutsu_). He used the laziness, stupidity, or other quirks of the guards to his advantage. In the rain or cold (_ametori no jutsu_, Eng.
the art of the birds in the rainy
), the guards preferred to stay away from their work or to carry it out half-heartedly. Usually, every distraction on the boring service was accepted with joy.
+
+Sometimes the Ninja would throw an object over a guard’s head to get his attention (_yoji gakure no jutsu_). This technique was carried out until the opponent was no longer interested in pursuing a crack in the branches. In addition, you could irritate him with animal sounds.
+
+A popular tactic was to hang a coat outside. When it was windy, it would make noise and attract the guards, allowing the Ninja to sneak away unmolested.
+
+## Avoiding Human Contact
+
+He tried to avoid any human contact on his night missions. Conflicts hindered him in his execution and cost time, it is possible that the order even failed because of it. But when it was unavoidable, he tried to carry the body of the guard into the thick branches of a tree.
+
+He liked to exploit people’s superstitions (_kyonin no jutsu_). Whether devil mask, fire spit, or various _evil_ animals such as snakes, toads, rats, or ravens, he used everything that brought him an advantage.
+
+When tasked with spreading terror and fear among his opponents, he liked to ambush, hit hard, and retreat. In this way, the morale of the troops was destroyed.
+
+He liked to hide in the castle’s beams before the battle and waited. He then set fires to various locations in the castle, sabotaged ammunition depots and storerooms, polluted wells, and destroyed equipment.

+
+## Oda Nobunaga’s Interest in Iga
+
+The Iga province was attacked twice by the Oda family in the late 16th century. The reason for this was actually not in the Iga region but the entire Ise region. For a long time, this region was ruled by the Kitabatake family. Kitabatake and the ruling Nikki family in the Iga region were well aware of the Ninja activities but did not intervene because they respected the incredible abilities of the Ninja. Kitabatake Tomonori even built a castle on Mount Maruyama in the middle of the Iga region to control Iga from here. However, he never completed this mission, probably because the people of Iga had such a close connection with the Ninja families.
+
+It all started in 1560 when Oda Nobunaga and his armies achieved great success. In 1568 he dethroned the last Ashikaga shogun in Kyōto and ordered his troops to conquer Ise because he was still surrounded by his enemies Mori, Takeda, and Uesugi. He needed control of the Tokaidō main road that traversed the northern Ise region. Kitabatake Tomonori lost Kanbe Castle and Kuwana Castle. Kuwana Castle was very important because of its strategic ability to defend the Tokaidō Strait. Oda’s successes on the battlefield continued, and he conquered Okawachi in fifty days, forcing Kitabatake Tomonori to agree to peace. The condition was that Kitabatake adopts Oda’s second son, Nobuo, who was twelve at the time.
+
+Kitabatake lost many territories in Ise as a reward for Oda’s generals, but he retained his post as a puppet Daimyō. He was later assassinated, perhaps by one of his former vassals, Tsuge Saburozaemon. This meant that Oda Nobuo inherited control of the province. The Kitabatake family, led by Kitabatake Tomoyari, gathered all their loyal Samurai and supporters from the Iga region to take revenge on Oda Nobuo. Tomoyari had been a priest in Nara but returned when Tomonori was assassinated. It is believed that Tsukahara supported Bokuden’s (one of the most famous swordsmen) son Tomoyari, but the uprising was crushed by Oda Nobuo’s general Takigawa Saburohei Kazumasu. The surviving Samurai fled to Iga, where they enlisted the help of Mori Motonari. Motonari’s region was not involved in the fight against Oda, but his forces began to harass Oda Nobunaga. This was reason enough to take on Motonari.
+
+## The Uprising of Iga
+
+What became known as **Iga no Ran** was an uprising that began in 1579 when Shimoyama Kai no Kami came to Nobuo to complain about the rest of the population of Iga. Nobuo felt he finally had a reason to prepare for battle by rebuilding the castle his stepfather, Kitabatake Tomonori, never finished. He ordered Takigawa Saburohei to complete the castle on Mount Maruyama.
+
+The castle towered 180 meters above the waters of the Hijiki, and although Takigawa Saburohei used his own Ninja to plan the invasion, many Iga Ninja decided to participate in the construction of the castle and returned with knowledge of the castle’s weak points.
+
+The leaders of Iga decided to attack before the castle was completed. Iga Samurai and Ninja attacked together, forcing Takigawa’s soldiers to retreat to the villages at the foot of the mountain because the castle was not yet strong enough to protect them. They were attacked by smaller groups of Samurai. Those soldiers who were holed up in the castle soon realized that the Iga soldiers knew how to get into the castle.
+
+They fled to join the rest of the Takigawa forces. Takigawa’s troops were herded into the flooded rice fields and into the forests. The battle continued into the night until they were defeated. Takigawa himself fled to Matsugashima and survived the battle. The next day, the Ninja and Samurai burned down the castle.
+
+After his defeat at Maruyama, Takigawa decided to avenge his loss of honor and supported Oda Nobuo when he decided to conquer Iga. Despite the advice of the rest of his vassals, Nobuo rode into battle. He planned to attack with 12,000 men through Matsugashima’s best three passes. Nobuo himself led the attack through the northern Nagano Pass. The residents of Iga used the Ninja to get the information in time and easily defeated Nobuo’s army.
+
+Takigawa attacked from the south through Oniboku Goe (Devil’s Pass). They were defeated in much the same way as Nobuo. At the same time, the Iga troops had an extra triumph when they exacted their revenge on Tsuge Saburozaemon who was accompanying Takigawa.
+
+The third and final attack struck between the other two attacks. The troops were led by Nagano Sakyo Tayu and Akiyama Ukyo Tayu. Upon reaching Iseji, they were lured to launch an attack on a village. They had long since passed the hidden Iga troops and were attacked from behind, which prevented any escape attempts and completely destroyed them. Nobuo narrowly escaped with his life and fled back to Matsushiga.

+
+## Location of the Iga Region
+
+The origin of Iga-Ryū-Ninjutsu can only be understood by taking a closer look at the Iga region. From the beginning, the Iga region belonged to the Ise province, but around the year 680, they were divided into two. Ise has always been one of the most important regions in Japan because it had a long coastline and the Tokaidō street between Edo and Kyōto passed through this region. Iga Province developed into a relatively self-contained region, surrounded by mountains on all sides except the northern side, near the Kōga region in the south of Omi Province. Ninpō culture was developed in these regions. Both regions, the Iga and Kōga regions were located relatively safely, just a little southeast of Kyōto, the capital of Japan, and south of the Tokaidō street. Thus, these regions were very centrally located and played an important role in the history of Japan.
+
+
+
+Now, to all these external circumstances, all one needs as an accelerator is General Ikai, a refugee from China with knowledge in strategy and the arts of war, and they had every opportunity for the development of their own independent Ryūha (sect, branch). Both, as a protection for their own existence and as a way to play an active role in the political development of Japan. In passing, it must be mentioned that in Sada (in Iga) there are places called Tojin Iwa (the Chinese Rock) and Karadobuchi (the Door to China’s Deep Water), which still remind us of the connection with China.
+
+Nearby, southeast of Iga in the Yoshino Mountains is the place where the leaders of the _shugendō_ sect lived. And south of Iga, located in the Kumano Mountains, is another sacred place of the _shugendō_ sect. It is very likely that these _yamabushi_ (mountain warriors) exchanged their philosophies and methods with the inhabitants of Iga.
+
+## The Iga-Ryū
+
+In the Iga-Ryū there were many other Ryū with their own specialties and traditions, but the origin of all Iga-Ryū martial arts is said to go back to Ikai, who fled China to a cave on Mount Takeo. What he brought with him from China was first and foremost the knowledge of _koshi jutsu_ (techniques against muscles and tendons), which he taught to Gamon Doshi (moralist), among many others. Gamon Doshi and his student Garyū Doshi are considered to be the founders of almost all martial arts in the region of Iga.
+
+But there is a problem with this theory. According to Master Hatsumi and other sources in Bujinkan, Ikai fled China sometime between the years 1040 and 1050. The reasons for his escape were that he had fought with the people of Kitan and Xia against King Jinso (Song Dynasty in China) and was defeated. However, according to the history books, the Kitan and Xia states were still victorious at that time, and only when Emperor Hui Zong allied with Aguda of the Ruzhen between 1123 and 1125 could the Kitan and Xia states be defeated. So either the data of Hatsumi must be reevaluated or a connection between Yo Gyokko and the fall of the Tang Dynasty must be found out and who brought _koshi jutsu_ to Japan.
+
+> It may also have been that Yo Gyokko brought _koshi jutsu_ and Ikai brought the knowledge of strategy and Hicho Kakuregata to Japan and from both systems the origin of the martial arts in Iga.
+>
+> **Hatsumi Masaaki**
+
+Garyū Doshi introduced the Hakuun-Ryū, a school developed and named by Hakuun Doshi. Hachiryū Nyudo is another name worth mentioning because he probably passed on Garyū’s knowledge to Tozawa Hakuunsai, the first official grandmaster of Gyokko-Ryū. Gyokko-Ryū is considered a _koshi jutsu_ school in most cases, but it is also an official school of ninpō.
+
+Hakuun-Ryū was passed on to Kagakure Doshi (also known as Kain Doshi or Kumogakure Doshi), and it was Kagakure who taught this system to Nishina Daisuke. Daisuke founded the Togakure-Ryū and this, together with the Gyokko-Ryū, is one of the oldest traditions in Iga. Both styles greatly influenced the other schools in Iga.
+
+Hatsumi Masaaki’s book
Essence of Ninjutsu mentions Iga Heinabe Yasukiyo, another student of Gamon Doji. Because he was given a piece of land, Iga Hattori Minamoto helped Yoritomo in his fight against the Taira clan. He is said to have built a castle that became the origin of the Iga-Ryū. But Iga Heinabe Yasukiyo is said to have lived in the late 11th century and Minamoto Yoritomo in the late 12th century. Therefore, this story is doubted. On the other hand, Iga Heinabe Yasukiyo seems to be the basis of knowledge that Iga Heinai Saemon no Jo Ienaga, his twelfth generation descendant, used when he founded a school also called Iga-Ryū but later renamed Kumogakure-Ryū _ninpō_ was renamed.
+
+There is another story that establishes that Ise Saburo Yoshimoru was allied with Minamoto Yoritomo’s brother in the Battle of Yoritomo. That fits better into the story, even if it’s not sure yet.
+
+All the different Iga-Ryū had their own line of _soke_ (Japanese
head of the family
), but the Iga-Ryū as a whole also had a lineage of important individuals called _jōnin_. It is not uncommon to find the names of _soke_ here as well, which were also _soke_ in other Iga-Ryū.
+
+## The Grand Masters of Iga-Ryū
+
+Below is a list of the Iga-Ryū _jōnin_ up to the end of the 16th century. The year mentioned is not exact or the year the individuals were grandmasters but the year they were active.
+
+1. Gamon Doji (1065-1068)
+ Garyū Doji (founder of the Hakuun-Ryū) (1074-1076)
+2. Unryū Doji (1074-1076)
+3. Iga Heinabe Yasukio (1096)
+4. Tozawa Hakuunsai (Founder of Gyokko-Ryū) (1159)
+5. Ise Saburo Yoshimoro (1159)
+6. Togakure Daisuke (founder of Togakure-Ryū) (1207-1210)
+7. Kumogakure gene on (1249-1255)
+8. Tozawanyodo Gen eisai (1334-1335)
+9. Hachimon Hyouun (1379-1380)
+10. Kuryuzu Hakuun (1394-1427)
+11. Tozawa Ryūtaro (1487-1488)
+12. Momochi Sandayu I (1532-1554)
+13. Iga Heinai Saemon no jo Ianega (Founder of Kumogakure-Ryū) (1532-1554)
+14. Kamihattori Heitaro Koreyu (Hattori Hanzo’s family) (1532-1554)
+15. Nakahattori Heijiro Yasuyori (1532-1554)
+16. Shimohattori Heijuro Yasunori (1532-1554)
+17. Momochi Sandayu II (1573-1591)
+
+## The Families of the Iga-Ryū
+
+The accumulated knowledge of the Iga-Ryū was developed and protected by 45 families. These families were:
+
+Tozawa, Fujiwara, Minamoto, Kuriyama, Taira, Momochi, Ishitani, Hattori, Toyata, Izumo, Ohkuni, Tsutsumi, Arima, Kimata, Hata, Mizuhari, Hanbe, Shima, Sawada, Togakure, Ise, Sakagami, Narita, Toda, Oda, Ooyama, Mori, Abe, Kataoka, Ueno, Otsuka, Ibuki, Kaneko, Kanbe, Kotani, Hisahara, Sugino, Kazama, Iida, Kimura, Iga, Fukii, Kashiwabara, Shindo, Suzuki.
+
+Some names are very interesting. For example, Tozawa, because Tozawa Hakuunsai was also the first _soke_ of the Gyokko-Ryū, one of the 9 schools in the Bujinkan.
+
+The Toda family is also interesting. Besides being the _soke_ of the Kumogakure-Ryū, they also inherited the Togakure-Ryū in the 17th century from the Natori family, who inherited the Togakure-Ryū again after all the Toda family members died. The Toda were also closely associated with the Tozawa.
+
+Momochi was one of the most famous families and Momochi Sandayu was without question the most famous Ninja leader along with Hanzo Hattori. Momochi Sandayu and three of his descendants were _soke_ in the Gyokko-Ryū and Koto-Ryū in the 16th century. They had also inherited schools from the Sakagami family. In the 17th century the Gyokko-Ryū, Koto-Ryū, Kumogakure-Ryū, and Togakure-Ryū were continued under Toda Seiryū Nobutsuna. Later, the Gyokushin-Ryū was also passed on to the Toda family. Other names that have a direct connection to Bujinkan are Ishitani, Izumo, and Iga.
+
+## Schools Related to the Iga-Ryū
+
+Here are some Ryū that were part of the Iga-Ryū and traditions of the Iga province:
+
+Hakuun-Ryū, Togakure-Ryū, Kumogakure-Ryū, Genjitsu-Ryū, Tenton Happo-Ryū, Goton-juppo-Ryū, Kadone-Ryū, Kukishinden-Ryū, Gyokko-Ryū, Koto-Ryū, Rikyoku-Ryū, Tsuji-ichimu-Ryū, Hattori-Ryū, Taki-Ryū, Yoshimori-Ryū, Uchikawa-Ryū, Gikan-Ryū, Gyokushin-Ryū, Takino-Ryū, Sawa-Ryū, Gen-Ryū, Momochi-Ryū, Ryūmon-Ryū, Iga-Ryū.
+
+This list is not complete, as many Ryū disappeared from history. The Iga-Ryū and Kumogakure-Ryū were a single Ryū because Iga-Ryū was simply renamed Kumogakure-Ryū. The Gikan-Ryū and Gyokushin-Ryū were both developed from the Gyokko-Ryū.
+
+An exact transcription of the Ryū’s histories is almost impossible. There are several reasons for this, firstly because the martial arts were often passed on as _kuden_ (word-of-mouth teachings) and not written down. Another thing is that the _soke_ often issued more than one _menkyo kaiden_ (final mastery of a martial art) to give the Ryū a better chance of surviving. Other Ryū, on the other hand, had only one person who would become the next _soke_, and if the master died unexpectedly, his Ryū died too.

+
+_Inrō_ was the Ninja’s first-aid kit. With this equipment, he mixed his poisons and medicines together.
+
+## Poisons
+
+A Ninja was adept at mixing poisons and drugs and was able to extract poison from plant, animal, or mineral products.
+
+Poison could be used to kill an opponent, but more often it was used to paralyze, stun, or incapacitate the opponent.
+
+Knowing whether a poison worked quickly or slowly was important to complete the job. Sometimes it was necessary for an opponent to be silent immediately, other times the Ninja wanted to get to safety before the poison took effect.
+
+Ninja knew all kinds of poisons, some smeared on their weapons, others mixed with food or drink, or released as poison gas. It is even said that flowers were poisoned.
+
+A simple method was to drag the weapons through horse manure before use. An opponent wounded with these weapons often developed muscle cramps shortly after being wounded and died of blood poisoning.
+
+A strange poison (_gyokuro_) was made from green tea buried in the ground for 30 to 40 days. Then this mixture was mixed with soya bean paste. If this drink was given to a sick person, they would die within a few days. It could take a month for a healthy person, but after 70 days they too died from the effects of the disease.
+
+A poison was made from green plums or peaches that was known for its quick lethal effects (_zagarashijaku_).
+
+The Ninja were probably also the inventors of poison gas, even if it was not usually used to kill, but only to stun. A little of this gas in the air and all the guards would become sluggish or fall asleep. So the Ninja could do his job without being bothered.
+
+One of these sleeping gases was made from the blood of a newt, a snake, and a mole. The tincture was then absorbed by a leaf. If you burned this paper, everyone would fall asleep from the smoke.
+
+In another sleeping gas, three powdered male rats, some paulownia tree leaves, a centipede, and a handful of cottonseeds were mixed together and the mixture pressed into a spherical shape. When this bullet was burned, anyone inhaling the fumes fell into a deep sleep.
+
+The Ninja made a liquid narcotic from ground hemp leaves, which he then mixed into tea.
+
+In order to paralyze an opponent and incapacitate him, the Ninja often used liquid or body liquids from toads, pufferfish, or other poisonous animals.
+
+To prevent an opponent from pursuing, the Ninja liked to use itching medicine made from stinging nettle.
+
+There is also said to have been a mushroom which, when eaten, gave the victim a fit of laughter and was easily overpowered.
+
+A horrific poison, the manufacture of which few people know today, was capable of driving a person insane. The only thing that can be made known to the public is that five to ten seeds of a plant were ground into powder and mixed with the food.
+
+There are a large number of plant poisons that are common in nature and were easy for the Ninja to obtain. Contemporary poisonous plants include Arum, broom, henbane, bean, Christmas rose, yew, aconite, foxglove, spotted hemlock, germer, gold lacquer, laburnum, autumn crocus, dog parsley, potato, tree of life, lupine, lily of the valley, oleander, spindle tree, castor bean, red bryony, sallow tree, common buttercup, celandine, daphne, datura, deadly nightshade, water hemlock, cypress spurge.
+
+Many of these poisons are not very dangerous, but with the right pharmacological knowledge and the right mixture, dangerous poisons can be made from them.
+
+One important aspect should always be considered: the dose makes the poison. Any food is a poison in the right amount. And in small doses, poison can even be used as a medicine, as is done in homeopathy.
+
+No one can say for sure how many people have been killed by poison over time. But this has certainly happened very often because poison used to be a surefire means of changing the succession of thrones or influencing politics. The medical examinations were still very poor at that time, and one could rarely recognize poisoning by a few clear signs.
+
+Even today, forensic doctors assume that a not inconsiderable number of deaths can be traced back to poisoning, which is usually not discovered if the person was already of advanced age because then a forensic medical examination is omitted. Undoubtedly, the heirs slowly and undetectably killed people they didn’t like over a longer period of time with small doses of poison.
+
+## Remedies and Healing Methods
+
+Since the Ninja were usually on their own for a long period of time, they had to be able to take care of themselves medically. He was able to heal minor as well as major injuries, poisoning, or evil.
+
+He treated sword wounds with a mixture of goatsfoot and black cowpea. Sometimes he would also put crushed narcissus roots on the wound. He used a paste of wheat flour and water to relieve bamboo cuttings, especially the pain. Monkshood, calamus, hemp, and chrysanthemums were used as painkillers. The Ninja placed crushed leeks on bullet wounds. To stop the blood flow from minor scratches, he uses the smoke from smoldering scraps of cloth. A mixture of tannin and Indian ink was applied to scalded skin to soothe it. If the Ninja had a major bleeding wound, he would use a mixture of chewed tea leaves and dry, powdered paulownia leaves. Various plants such as Japanese acacia, mugwort, peony, and thuja species could be used to stop bleeding. For sprains and strains, he used philodendron amurense half crushed and half raw, mixed it with vinegar, and applied it to the skin. To combat wound infection, the Ninja put fish skin on the wound and changed it from time to time.
+
+If he ate spoiled food, he ate the same food again in a charred form.
+
+The Ninja are said to have been able to fight cancer. A branch of an old wisteria tree, preferably with growth, was ground into powder, mixed with water, and drunk. The intake of three grams of water nut seed powder or water chestnut powder daily is said to have been used as a cancer cure.
+
+Some Ninja also mastered the art of resuscitation. In Japanese _shiatsu_, fainting or other ailments can be alleviated or cured by massage and stimulation on certain parts of the body.
+
+## Food
+
+A Ninja always took an emergency ration with him on a mission. This consisted of rice, wheat flour, dried flour roots, dried trout, dried plums, and pine powder. Genmai juice, a drink made from unpolished rice, restored his strength.
+
+To quench his thirst, the Ninja used peppermint powder and salt plums. If his water reserves were exhausted, he could also use a certain leek plant. 30 sesame seeds are said to have given him temporary relief from thirst.
+
+The Ninja ate foods that were normal and common in their habitat. These included bean paste, buckwheat flour, fish, vegetables, prunes, sesame, tofu, unpolished rice, and other foods in the Japanese diet.
+
+This menu is very difficult for a non-Japanese to stick to and takes some getting used to, but it doesn’t have to be. Hatsumi once said that the diet differs in different countries. The important thing is that you eat a balanced diet and don’t eat too much meat.

+
+## The Great Campaign Against Iga
+
+Oda Nobunaga was otherwise busy for the next two years before he could deal with the problem in Iga. When two Samurai, Fukuchi Iyo from a village above Tsuges in Iga, and his comrade Mimisu Iyajiro, offered him their services as advisors and guides, Nobunaga saw his chance to finally subjugate Iga because they did not accept his supremacy. Oda Nobunaga planned a far larger operation than his son Oda Nobuo did when he failed in 1579.
+
+Oda Nobunaga planned to attack from six sides simultaneously, with Fukuchi Iyo and Mimisu Iyajiro advancing through Kōga Province from the north, as that route was the most difficult to defend.
+
+Oda Nobunaga himself led the forces that left Azuchi in August 1581, but after only half a day’s march he fell ill and had to call off the operation. By September his health was restored and he summoned his generals. His plan was to burn and devastate as much as possible to prevent the tactics of the people of Iga.
+
+The people of Iga found out about the six armies in good time, but they did not have the resources to defeat such a large force.
+
+## Nobunaga’s Army
+
+The troops in Iga were about 4,000 soldiers, so they decided to concentrate their forces in two places and defend from there. One was the Heirakuji Temple on a small hill in Ueno Village, the site where Iga Ueno Castle now stands. The other place was Mount Tendoyama, not far from where Maruyama Castle once stood. Nobunaga’s troops used six different routes:
+
+### Iseji
+
+The route via Iseji was commanded by Oda Nobuo or Kitabatake Chujo Nobuo as he was also known. At his side rode Yoshida Goro and Oda Shichibei no Jo Nobuzuma along with more than 10,000 soldiers and mounted Samurai. He was also joined by all those who had already taken part in the 1579 invasion, alongside other Takigawa Saburohei Kazumasu, Nagano Sakyo, and Hioki Daizenryo, but this time together in one army. After a quick push, Nobuo split his army into three to attack the villages and forts where refugees from Iga were staying. Takigawa besieged two fortresses, Tanenama no Sho and Kunimiyama, while Nagano and Hioki attacked the Valley of Ao and the fortress at Kashiwao. He did not meet much resistance during his campaign, but they were often harassed by the besieged. During the nights they launched attacks on the besiegers.
+
+### Tsuge
+
+More than 12,000 soldiers came through the Kōga area from the north. They moved past Tsuge near the borders further south. The army was led by Niwa Gorozaemon Nagashida, Takigawa Sakon Shogen, Takigawa Yoshidaou, Wakabe Sakyo no Shinjuko, and Todo Shogen. Niwa Nagashida’s camp was attacked by Ninja at every opportunity, so that in the end no one dared to sleep for fear of being killed.
+
+### Tamataki
+
+Over 7,000 soldiers also came through the Kōga area from the north, but chose the western route through the village of Tamataki. The army was commanded by Gamo Hida no Kami Shikyo, Wakizaka Jinnai Yasuharu and Yamaoka Shukei Gashira, which is not a name but means purser. The army is said to have encountered resistance on its way through Kōga. Apparently, it was a member of the Mochizuke family named Mochizuke Chotaro who had a duel with a man named Yamauchi Zaemon Dono. One reason for this may have been the alliance of the Iga and Kōga families.
+
+### Tarao
+
+From the northwest came Hori Kudaro Hidemasa and Tarao Shirobei Mitsuhiro with 2,300 men. The people of the northwest region of Iga decided to defend Kannoji, a Buddhist temple on Mount Hijiyama west of Ueno.
+
+### Yamato Hase
+
+Masanoiyabei Nagamasa, Shinjo Suruga no Kami, Ikoma Gagaku Kashira, Mori Iki no Kami, Toda Danzo Shoshitsu, Sawabara Jiro, Akiyama Sanou Tayu and Yoshino no Miya Naishoyu attacked from Yamato province in the south with 10,000 troops. They besieged Kashiwabara, which was under the supreme command of Takano, a Samurai who was an expert at night raids. He used ancient methods, those of Kusunoki Masashige, the founder of Kusunoki-Ryū. One technique he used was to have women and children wave torches, giving the impression of an impending attack and spreading fear and disorder in enemy camps.
+
+### Kasama
+
+Tsutsui Junke and his nephew Tsutsui Shiro Sadatsugu also attacked from Yamato to the south, but via the town of Kasama further north than Asano Nagamasa’s army. The army consisted of 3,000 soldiers, but they moved north to help Gamo Ujisato in besieging Hijiyama instead of besieging Kashiwabara.
+
+### Hijiyama
+
+On September 27, Gamo Ujisato, Wakizaka Yamaoka, and Tsutsui Hijiyama attacked together, but small groups of Ninja were hiding along the embankment. It was the same strategy that had been used successfully in Nobuo’s invasion. They attacked Gamo on his way up, inflicting so much damage that Gamo’s troops were badly wounded and lacked fighting spirit by the time they reached the mountaintop.
+
+## Guerrilla Tactics Against the Attackers
+
+Two men from Iga, Momoda Tobei and Yokoyama Jinsuke managed to reach the foot of the mountain and take the heads of Gamo’s two sons. The besiegers immediately broke off their attack and retreated. Momoda Tobei, Fukukita Shogen, Mori Shirozaemon, Machii Kiyobei, Yokoyama Jinsuke, Yamada Kanshiro and another man who was called _the Seven Spears_ were reaped great honors for their success in battle.
+
+Iga’s forces decided to continue their night raids against the enemy. They prepared a swift attack on Tsutsui’s army, surprising him. His soldiers didn’t even have time to put on their armor, and a wind blew out all the torches. Because of the darkness, Tsutsui’s soldiers slaughtered each other. The troops of Iga, on the other hand, used code words to know who was enemy or friend. Another attack on Tsutsui’s army was also successful.
+
+## The Defeat of the Insurgents
+
+After successfully repelling all resistance, Oda Nobunaga’s armies rallied around Hijiyama. 30,000 soldiers from his once 44,300 strong army surrounded the mountain. Due to the huge advantage, Oda Nobunaga failed to win the fight by force of arms. Because the weather was dry and the wind was strong, Oda Nobunaga decided to set fire to the entire area. Those who tried to escape from the flames were driven back.
+
+This was the end of the last major uprising in Iga and those who continued to fight Oda spread throughout the region. Whether the fall of Hijiyama took place on September 10 or 11, 1581, or as late as early October is unclear. The Nobunaga’s forces began their hunt for the last resisters, and it was not until 1582 that all resistance was defeated.
+
+## The Survivors Are Hiding
+
+Few of Iga’s once 4,000-strong army remained, and many innocents lost their lives in Nobunaga’s furious pursuit of Ninja. Although most knew about the Ninja, only a minority belonged to the clans or were trained in the art of Ninjutsu. Some sources report that only eight survivors from the three Hattori clans remain. Many fled to other areas of Japan. A _jōnin_ of the Hattori family was killed in Tsutsui’s attack on Kikyo Castle.
+
+A final attempt to assassinate Nobunaga was made by Kido, Harada, and Jindai. The whole thing took place when Oda Nobunaga was traveling through Iga to observe the successes of his invasion. Oda Nobunaga reached a place called Ichinomya. Kido, Harada and Jindai had set up three cannons from three different directions. They opened fire on the place where Nobunaga and his followers were sitting, but Nobunaga managed to survive, but seven or eight of his followers perished. Kido, Harada and Jindai managed to escape into the woods.
+
+Momochi Sandayu, a well-known _jōnin_, also managed to escape from Nobunaga’s troops with some of his men. They fled to the town of Ryugu near Ude Sanbonmatsu in Yamato Province, where Momochi and his men stayed until June 10, 1582, although his men wanted to continue fighting. On June 10, word reached them that Oda Nobunaga had been assassinated by his own general, Akechi Mitsuhide.

+
+## Fitness and Mobility
+
+_Jūnantaisō_ is the Ninja conditioning training to improve suppleness, speed and reactions in order to be able to use the techniques of _taijutsu_ effectively. In Ninjutsu, strength is gained through flexibility. Muscles and tendons regain their natural elasticity. _Jūnantaisō_ – in connection with a proper diet – keeps the body healthy into old age.
+
+The muscular system can be divided into two areas. Weak muscles are strengthened with fast repetition exercises. With this type of training, which is characterized by rapid alternations of contraction and relaxation, a feeling of physical exhaustion may occur.
+
+The second system allows rigid and immobile muscles to be improved through stretching. This type of training is also known from Indian yoga. In this type of training, the positions are held for a few seconds while the muscles are relaxed.
+
+It should always be borne in mind that _jūnantaisō_ is not a simple _warm-up_ before combat practice, but provides a vital, healthy foundation. The body learns to function in harmony with all parts again.
+
+Below are some examples from the _jūnantaisō_, but there are countless other exercises to improve flexibility, strength, and endurance. Pull-ups, sit-ups, various push-ups, and stretching exercises for all parts of the body.
+

+
+## Expression of Inner Attitude
+
+The fighting positions in _taijutsu_ are more than rules of how to move the body. They are best described if you see them as an expression of the inner attitude. In battle or in life it is always important that body and mind are one. When performed correctly, the _kamae_ reflect the heart of the Ninja.
+
+The point of _kamae_ is not, as in other martial arts, that every fighter adopts the same position, whether or not it suits his body, nor is the point of _kamae_ to imitate any animal, but to move naturally, body, Spirit and soul are said to be one (_shingitai_).
+
+## Flowing, Not Static

+The positions are not to be viewed as static forms, like a photograph, but are only occupied as long as they are useful. The fighting positions flow into each other. To e.g. For example, to avoid a deep kick, one could back away from _shizen no kamae_ in _ichimonji no kamae_, immediately raise the attacked foot (_hichō no kamae_), kick the opponent’s knee, and land in _jūmonji no kamae_, immediately in _kosei no kamae_ switch and execute a striking technique against the opponent’s back. What is certainly clear here is that there are five moves in a 2-3 second long combat sequence. Each position is maintained only as long as necessary. Under no circumstances does one stay longer in one position, as is common in other martial arts.
+
+## Natural Movement
+
+As the student develops, the _kamae_ become less and less important as specific positions and are incorporated into the fighter’s natural movement. Once these basics are mastered, the most important combat stance becomes the _non-combat stance_.
+
+There are a large number of combat positions, e.g. also differ among the Ryū or bear other names, in addition, each fighting position can be taken at different heights (e.g. also kneeling) or be aimed at different heights.
+
+Some of these positions are explained and shown below:
+
+## Observational Positions
+
+The observation fighting positions are the basic positions. These stances are standing or sitting stances that one would normally be in when being attacked. From these positions you also bow and show respect to your opponent. Because these poses were developed in the Eastern world, where there are no chairs like in the Western world, the observing poses are natural sitting and standing positions.
+
+### Gasshō no kamae
+
+{% figure "Gasshō no kamae" %}
+
+
+
+{% endfigure %}
+
+The _gassho no kamae_ posture is used for the standing salute. Both feet are firmly on the floor, hands are clasped in front of the torso, elbows are slightly raised. The gaze goes straight over the fingertips to the opponent.
+
+### Fudōza no kamae
+
+{% figure "Fudoza no kamae" %}
+
+
+
+{% endfigure %}
+
+The _fudoza no kamae_ posture is the traditional Japanese sitting posture. The left leg is folded under the body and the seat rests on the ankle of the left foot. The right leg is pulled in front of the body with the sole of the right foot against the knee. The back is straight and the spine is in its natural position. The view goes straight ahead.
+
+### Seiza no kamae
+
+{% figure "Seiza no kamae" %}
+
+
+
+{% endfigure %}
+
+The _seiza no kamae_ pose is the traditional Japanese kneeling pose. The legs are crossed behind the body and the seat rests on the soles of the feet. The upper body is straight, the knees slightly apart. The hands rest on the thighs. To show respect, bend your torso forward and place your palms on the floor in front of you.
+
+## Defending Positions
+
+The defending battle stances are used when you need to respond to an attack by blocking or dodging before you can launch a counterattack. The body slips or slides in or out, away from the attack. You can then block or attack from this position.
+
+### Ichi no kamae
+
+{% figure "Ichi no kamae" %}
+
+
+
+{% endfigure %}
+
+_Ichi no Kamae_ is performed by stepping one leg forward in _shizen_ and allowing most of the body weight to rest on the back leg. The body is turned obliquely away from the enemy. The front hand points towards the enemy, the back hand remains as a fist on the belt. This position is the position taken before _ichimonji no kamae_.
+
+### Ichimonji no kamae
+
+{% figure "Ichimonji no kamae" %}
+
+
+
+{% endfigure %}
+
+The _ichimonji no kamae_ stance is performed with the body pulling back and dodging away from the attack. The back leg keeps the body upright. The shoulders are relaxed, the hips are turned so that the vital points are hidden. The open hands protect the face and body or intercept the opponent’s attack.
+
+### Doko no kamae
+
+{% figure "Doko no kamae" %}
+
+
+
+{% endfigure %}
+
+The _doko no kamae_ posture is performed with the body pulling back and dodging away from the attack. The back leg keeps the body upright and the front leg prepares to push the body back even further if the need arises. The front hand blocks or intercepts the opponent’s blows, the back hand is held close to the ear and prepares a counter-blow.
+
+### Hicho no kamae
+
+{% figure "Hichō no kamae" %}
+
+
+
+{% endfigure %}
+
+The _hichō no kamae_ stance is used to evade an attack and the front leg is waiting to attack the opponent. To keep the balance, the leg standing on the floor is slightly bent. The arms are in a position to grab, block, or deliver punches.
+
+## Receiving Positions
+
+The receiving fighting stances are used when responding to attacks with techniques that harmonize with the opponent’s power or go along with it. The body rotates or moves sideways to blend in with the enemy’s movement. Defenses are applied in the same way.
+
+### Shizen no kamae
+
+{% figure "Shizen no kamae" %}
+
+
+
+{% endfigure %}
+
+The _Shizen no kamae_ posture is man’s natural standing position. The mind is alert, the body is relaxed and ready to move and react to the opponent. Body weight is on both feet, shoulders are relaxed, and arms hang naturally at your sides. This stance will be found in most attacks as it is the natural movement of walking or standing. Therefore, it is also the most important position and should be trained well.
+
+### Hanmi no kamae
+
+{% figure "Hanmi no kamae" %}
+
+
+
+{% endfigure %}
+
+From _shizen no kamae_ for _hanmi no kamae_ you simply take a small step forward with one leg. The body is turned away from the opponent.
+
+### Goku no kamae
+
+{% figure "Goku no kamae" %}
+
+
+
+{% endfigure %}
+
+In _goku no kamae_ you turn your body from _shizen no kamae_ by 45° away from the opponent. The hands hang down naturally, as in _shizen_, the front hand is open, the back in _fudō ken_.
+
+### Hira (ichimonji) no kamae
+
+{% figure "Hira (ichimonji) no kamae" %}
+
+
+
+{% endfigure %}
+
+The _hira ichimonji no kamae_ pose is a balanced, standing position from which the body can deviate. Body weight rests equally on both feet, both arms stretched out to the sides. They can be used to sweep, grab, or catch blows.
+
+### Hoko no kamae
+
+{% figure "Hoko no kamae" %}
+
+
+
+{% endfigure %}
+
+The _hoko no kamae_ posture is another posture from which the body can respond to an attack. The weight rests on both feet, the arms are held slightly bent over the shoulders. The arms can be used to catch, redirect, or deliver punches.
+
+## Attacking Positions
+
+The attacking combat stances are used when going from defense to attack. The positions are only partly defensive and for the most part offensive. Kicks, punches and throws are applied from these positions.
+
+### Jūmonji no kamae
+
+{% figure "Jūmonji no kamae" %}
+
+
+
+{% endfigure %}
+
+The _jūmonji no kamae_ posture is easily recognized by the crossed wrists. This hand position protects the body during an attack. Elbows cover ribs, fists protect neck and face before delivering a punch. The weight is slightly more on the front foot and the back foot pushes the body forward.
+
+### Kosei no kamae
+
+{% figure "Kosei no kamae" %}
+
+
+
+{% endfigure %}
+
+The _kosei no kamae_ stance is used to attack, but it also allows you to intercept possible blows. The front hand is used to grab, redirect, or get the opponent’s attention. The back hand performs the attack.

+
+## Founding of the Kōga-Ryū
+
+The Kōga-Ryū Ninjutsu was the other Ninja clan of great importance in Japan. It was founded by 53 families, probably in the Tenkyo period between 938 and 946.
+
+After Mochizuki Saburi Kameie distinguished himself in the war against the Taira no Masakado, he was given some land southeast of Omo Province. The region was called Kōga Gun, so Mochizuke changed its name to Kōga Oni no Kami Kameie. It was his son Oni no Kami Iechika, a talent in the military arts and in literature, who is said to have founded the Kōga-Ryū. He is said to have learned _genjutsu_ (the art of illusion) from the Buddhist monk Tatsumaki Hoshi who lived in the area.
+
+The tradition endured for seven generations, Oni no Kami Ienari, Iesada, Ienaga, Iekiyo, Ietoo, Ieyoshi, and Yoshiyasu, before expanding to other families, Mochizuki, Ugai, Naiki, and Akutagawa. These five families were joined by the remaining troops from the north and south of the kingdom during the Namboku War (1335-1395). With the help of the Kōga-Ryū, they grew to 53 families. Some of these families of the Kōga-Ryū were:
+
+Koga-ryu, Shinpi-ryu, Taira-ryu, Isshu-ryu, Byaku-ryu, Tengu-ryu, Taro-ryu, Kuruya-ryu, Tomo-ryu, Tatara-ryu, Sugawara-ryu, Otomo-ryu, Hiryu- Ryū, Fujiwara-ryu, Sasaki-ryu, Tachibana-ryu, Kawachi-yon-tengu-ryu.
+
+## The Leaders of the Kōga-Ryū
+
+As the Kōga-Ryū grew, there were eight families that controlled the other Ryū in Kōga. These eight families were Kōga, Mochizuki, Ugai, Naikii, Akutagawa, Ueno, Ban and Nagano. But also groups in Kōga like Hiryūgumi, Kakuryūgumi, Tachibana Hachitengu Gumi, and Kawachi Yon Tengu Gumi had very capable masters.
+
+During the Hokuto period (1441-1451), the leaders were Koga Saburo, Mochizuki Goro, Ugai Ryūhoshi, Naiki Fujibe, and Akutagawa Kazuma. During the Bunmei period (1469-1487), it was Kōga Saburo II, Mochizuki Yajiro, Ugai Chiaki, Naiki Gohei, and Akutagawa Tenpei who were from the Sasaki family who were the Daimyō (
Big Name
, wealthy landowner) in this area, were recruited to lead the troops against Ashikaga Yoshizawa.
+
+Almost 100 years later, the Sasaki family recruited Ninja again. This time it were Ninja from the Kōga and Iga regions in 1570. They also recruited Samurai from Kōga with the aim of destroying Oda Nobunaga. The Samurai were trained intensively for a short period of time so that they could execute the combat strategies of the _jōnin_.
+
+Sasaki’s army was divided into three divisions, the first being led by Ninja of Mikumo-Ryū, Takanose-Ryū, Mizuhara-Ryū, and Inui-Ryū. The second was led by the other 53 Kōga families and the third was by the Samurai Sasaki. In the battle, Mikumo Iyo Kami, who was leading one of Sasaki’s armies, suddenly switched sides and attacked Sasaki’s army from the rear, resulting in their defeat. Sasaki himself barely escaped.
+
+## Tokugawa Ieyasu Deploys Kōga Ninja
+
+When Tokugawa Ieyasu was fighting for power in Japan, Fushima Castle near Kyōto was under siege. They had to defend themselves against the armies to the west long enough to give the Tokugawa army enough time to regroup to fight at Sekigahara (site of the civil war’s final decisive battle) to the east. 400 Ninja of the Kōga region helped defend it. Some of them were inside the castle, others terrorized the enemy outside with various attacks. About 100 of them died, and after Tokugawa was victorious, they held a ceremony and it is mentioned that Mochizuki and Arakawa were killed.
+
+## The Last Mission of the Kōga Ninja
+
+One of the last times the Kōga Ninja became active was at the battle of **Shimabara no Ran** (site of the battle in the Christian Rebellion), when Christian Samurai started a rebellion and seized the Hara Castle in Shimabara province on Kyushu occupied. Ten Ninja from the Kōga region were sent by Izumo Kami Nobutsuna to gather information for the Shōgun’s Samurai to prepare to attack the castle.
+
+They were led by Mochizuki Heidayu, 63 years old, and Akutagawa Kiyouemon, 60 years old, both veterans of the Battle of **Sekigahara**. The others from Kōga were:
+
+- Ivane Kanbei, 56 years old
+- Tomei Gohei, 53 years old
+- Natsumi Kakunosuke, 41 years old
+- Akutagawa Shichirobei, 25 years old
+- Kamogai Kanuemon, 56 years old
+- Ivani Kanbei, 45 years old
+- Mochizuki Yoemon, 33 years old
+- Yamanaka Jutaya, 24 years old
+
+They arrived on January 4th, 1638 and their first task was to make a map of the area around the castle. Just 15 days later, they sent a detailed map of the castle and forces to Edo (present-day Tōkyō) to the shogun Tokugawa Iemitsu.
+
+It is also said that the Ninja from Kōga, or _ongyo no mono_ (hidden persons) as they were also called, snuck into the castle every night without any problem. On January 21, they stole food from the castle as their food supplies were running low. They also managed to learn some secret passwords.
+
+On January 27, five Kōga Ninja managed to get into the castle disguised as soldiers. They were Mochizuki Yoemon, Arakawa Shichirobei, Natsume Kakanosuke, Yamanaka Jutayu, and Tomo Gohei. The besiegers fired their firearms, and the enemies snuffed out their torches so they could no longer hit. Late that night, as the guards began to relax, the five climbed over the walls under cover of darkness.
+
+Arakawa didn’t pay enough attention and fell into a hole, Mochizuki immediately rushed to his aid. But because of the noise, the guards immediately lit the torches again, and they were spotted. Mochizuki and Arakawa ran through the troops, grabbing one of the Christian flags along the way, and were decided. All five managed to escape, but Mochizuki and Arakawa were wounded.
+
+When the castle was attacked on February 24, the Kōga Ninja served as liaisons between the units. Incidentally, Miyamoto Musashi (the most famous swordmaster in Japan) helped the shogun plan the battle. But he was hit by a rock thrown from the wall by a woman and had to retreat, complaining about the loss of his youthful vigor.
+
+## The Last Kōga Ninja
+
+It is said that the Kōga-Ryū survived until the middle of the 20th century through Fujita Seiko (1899-1966). He is said to have been the 14th _soke_ of the Kōga-Ryū. During World War II he led small units in the jungles. At the Tokyo Olympics in 1964, he tried to get athletes to train using Ninja methods. At the time, he drew attention to himself with spectacular demonstrations. Fujita Seiko died of cirrhosis of the liver at his home in Tōkyō on January 4, 1966, at the age of 67. He was the Grand Master of Kōga Ninja Ryū Jūjutsu and the 14th _soke_ of Sato Ryū _kenpō_. According to official information, he never passed on a license to teach the Kōga-Ryū to students.
+
+There is a book called
Ninjutsu no Gokui written by Gingetsu, who learned the techniques and history from Tanemura Ihachiro, a _jōnin_ of the Kōga-Ryū. The techniques described in this book are very similar to those of the Iga Togakure-Ryū.

+
+## The School of Knocking Down the Tiger
+
+It is believed that Koto-Ryū _koppō jutsu_ came from China via Korea, brought by Chan Busho, a Chinese warrior. But that would have been many hundreds of years before the founding of the Koto-Ryū. The exact origin of Ryū is not known, but the techniques were summarized in 1542 by Sakagami Taro Kunishige in _ryuha_. He was also the _sōke_ of the Gyokko-Ryū. Both styles have many similarities.
+
+Many Ninja and Samurai have been trained in the methods of koto-Ryū. Momochi Sandayu taught Ishikawa Goemon, the infamous Ninja who was a criminal. Momochi always denied that Ishikawa Goemon was ever a member of his clan.
+
+Goemon was seen as the _Ninja Robin Hood_ and was probably caught and scalded to death in boiling oil. Some historians, including Takamatsu Toshitsugu, believe he was never caught, the _bakufu_ was just too embarrassed to admit it. In many cases, the story passed down orally is more believable than the written word.
+
+The Koto-Ryū contains the complete _kyusho_ (Atemi pressure points). The Ryū had a very rare and extraordinary method of _kenjutsu_ in which the sword was held as if the swordsman were incompetent, grips and stances being constantly altered.
+
+There is also a unique stance in this Ryū, the _mangetsu no kamae_, in which the sword is held above the head to blind the opponent with the sunlight on the blade. Or when it rained, the blood gutter was used to collect water, which was then used to blind the enemy’s eyes.
+
+Another specialty of the Koto-Ryū is not to look your opponent in the eye, but between the eyebrows. So he can’t see the intentions but thinks he’s making eye contact, which will confuse him.
+
+Takamatsu Toshitsugu began his training in Koto-Ryū when he was 9 years old and was declared a master at 13.
+
+In 1960, Takamatsu is said to have convinced a journalist from the Tōkyō Sport Newspaper of the effectiveness of the koto-Ryū by drilling five holes with his fingers in the bark of a tree.

+The lion is a powerful animal and is considered mythical. Also in front of temples, you can often see a lion on both sides. Through _tō_ the Ninja gains the ability to move in harmony with the universe.
+

+## Sha (者) – Uchijishiin
+
+_Sha_ stands for our internal organs. When the Ninja uses this mark, he becomes able to heal himself and others. He creates a healthy environment around himself.
+

+
+## Kai (皆) – Gebakukenin
+
+_Kai_ represents the man striving to draw near to God. The sign, by the way, is the same as when praying. When the Ninja uses this mark, all illusion is prevented and consciousness absorbs far more. The Ninja thus becomes able to anticipate and anticipate danger.

+
+## Retsu (列) – Chikenin
+
+The left index finger represents humanity in this world surrounded by pure knowledge. Together they represent the unity of the material and spiritual worlds. _Retsu_ allows the Ninja to rule space and time. He becomes able to take his mind to other places or other times and thus gather knowledge to solve his problem.
+

+
+## Zai (在) – Nichirinin

+
+## Zen (前) – Ongyoin
+
+This sign symbolizes the fully enlightened one who has seen through all things. Since an enlightened one can become the target of ridicule or envy, the Ninja uses this symbol to receive the protection of the cosmic forces. So he becomes invisible to bad and low people and can disappear from the eyes of others.

+
+This school is the one with the most connections and relatives to all Bujinkan Ryūha. There are other _sōke_ of Kukishin-Ryū, e.g. the Hontai-yoshin-Ryū. As far as the story goes, the Kukishinden-Ryū is a branch school of the Kukishin-Ryū that Takamatsu was allowed to found in gratitude for his reconstruction of the _densho_. He was originally declared the _sōke_ of the Kukishin-Ryū, but had to relinquish that title to Iwami Nangaku because he went missing while traveling in China.
+
+Aikido is also said to have descended from the Kukishin-Ryū, Ueshiba Morihei is said to have learned his staff techniques from the _sōke_ of the Kukishin-Ryū.

+
+## The School of the Hidden Cloud
+
+The _taijutsu_ of Kumogakure-Ryū is very similar to that of Togakure-Ryū. Probably the Kumogakure-Ryū was founded by the Toda family.
+
+The Kumogakure-Ryū Ninja went into battle in armored clothing. Another interesting thing is that a demon mask was sometimes worn in this Ryū. One of the Kumogakure-Ryū’s special weapons is the _kama yari_ (hook spear). When fighting swordtails, hooks were used to deflect blows. However, the hooks were also used to kill enemies from above. In the _densho_ of the Kumogakure-Ryū, a Ninja named Sarutobi Sasuke is mentioned as using the hook spear to move from tree to tree. Another specialty is survival training and the art of lighting fires in all situations.
+

+
+## Female Ninja
+
+In 1561, the Japanese warlord Mochizuki Moritoki was killed in the famous Battle of Kawanakajima. His wife Chiyome then placed herself under the protection of her late husband’s uncle, the powerful Takeda Shingen. Rather than retiring to a religious order and leading the quiet life of a nun, as was customary in such situations, the dynamic Mochizuki widow continued to vigorously support the great Daimyō Takeda’s aspirations to power. In response to his question, she agreed to set up a network of _kunoichi_ agents. It was to become one of the most effective and discreet of all _sengoku jidai_.
+
+According to Shingen Takeda’s idea, Mochizuki Chiyome trained a group of trained _miko_ (female temple servants) who, in addition to their actual duties, were employed for espionage, surveillance, or courier activities in the Kai area (present-day Yamanashi) of the Takeda dominion, as well as in the Shinano territory (today Niigata) could be used. The latter area, in particular, was of the greatest strategic interest, as both Takeda Shingen and his rival Uesugi Kenshin considered it a prime target for their future conquests.
+
+## Spies and Informants
+
+During his reign, Takeda placed great emphasis on the services of his Ninja spies. He recruited them both from his own domain and the ranks of his opponents. The _kunoichi_ were just another link in his chain of informants. They served him well for intelligence gathering or checking other agents’ reports. The young temple servants could easily travel around and contact the local spies without arousing suspicion. In this way, the power and knowledge of the Takeda family could be increased even further.
+
+Chiyome established her underground school in Nazu, a village in Chiisa Gun (Shinshu area, now Nagano), and began her work as the director of a school for female Ninja. Since the _miko_ always had to be unmarried young girls, Mochizuki Chiyome began to look for suitable candidates among the countless children orphaned and homeless as a result of the civil wars. The _kunoichi_ trainer became the foster mom to every abandoned or runaway girl who found her way to the Shinshu area. In the eyes of the other residents of Nazu, Chiyome was a kind, warm-hearted woman who struggled with all her might to save young single girls from poverty and give them a home and instill spiritual values.
+
+## Female Ninja Training
+
+The girls were taught the customs, duties, and knowledge of the _miko_ virgins who served the priests of the Shinto shrines. In addition to this basic training, Chiyome’s protégés were also subjected to an indoctrination process that was intended to guarantee absolute loyalty later on. By constantly reminding the girls that it was she who had lifted them from their poverty and made this new life possible for them, she emotionally bound the future _kunoichi_ to her. Again and again, she asked her protégés to remember their childhood. Who was to blame for their poverty at the time? Who had betrayed her? Who found them in this unhappy time and gave them a new life when all seemed lost? Gradually, the girls were led to believe that their only chance of survival was to maintain strong bonds with their sisters and to show unwavering loyalty to Mochizuki Chiyome.
+
+In a third phase of the training, the trainer taught her students how to obtain valuable information, assess situations correctly, use (false) rumors to create confusion and disputes, identify reliable messengers who forward important messages to other _miko-kunoichi_, disguise themselves, and how one can, if necessary, use the feminine charms to manipulate men. Once training and indoctrination at the Ninja academy in Nazu was complete, the girls became active agents of Mochizuki’s _kunoichi_ squad.
+
+In this way, important information from the two target provinces was collected. In addition, Chiyome had travelers who had passed through the areas concerned questioned in detail and was thus able to give Takeda Shingen an exact picture of the political and military situation. To preserve the effectiveness and anonymity of the _kunoichi_ ring, Mochizuki’s Chiyome role was not known to anyone but the general himself; he did not share this secret even with his closest associates.
+
+## Similarities and Differences to Ninja
+
+The medieval _kunoichi_ were trained similarly to their male combatants, but with more emphasis on the more refined aspects of hand-to-hand combat. The male Ninja’s combat tactics and guerrilla warfare replaced the females with skills such as practical psychology, manipulation techniques, and intuition training. Of course, preparation for active service also included solid basic training in the Ninjutsu martial arts of _taijutsu_, _bōjutsu_ and _hanbōjutsu_, _tantōjutsu_, _yarijutsu_, and _kenjutsu_. The individual fighting techniques were adapted to the specific situation of the physically weaker woman and included, among other things, Escape methods and fending off stronger male opponents; Assaults on guard posts or military positions, similar to those of a shock troop, were reserved for the male Ninja.

+title: "Mikkyō"
+priority: 500
+date: 2006-04-02T14:34:00+02:00
+author: "Stefan Imhoff"
+excerpt: "One of the esoteric teachings on which the philosophy of Ninjutsu is based is the mikkyo. Originating in India and brought to Japan from China by Japanese monks, this teaching is an interesting addition to the spiritual growth of the Ninja."
+translationKey: "mikkyoPage"
+categories:
+ - philosophy
+ - religion
+---
+
+## In Tune With All Things
+
+To become attuned to all things and become a thoroughly natural creature, the Ninja employed the _ninpō mikkyō_ (tantric teachings of Buddhism). The _mikkyō_ says there is no coincidence. All that we see as good or bad luck are unchanneled forces manifesting in our lives. This means that a correct mental attitude is necessary to be able to comprehend reality in all its perfection.
+
+## Ninja and Science
+
+The Ninja were both scientists, employed and interested in the workings of organisms and natural processes. But at the same time, they were also interested in deeper spiritual and _occult_ phenomena. They trusted in their effects, which had often proven themselves over the many centuries since their creation.
+
+Today’s science is not mature enough for many things, and decoding the DNA code is only scratching the surface. It will still take a very long time before perhaps one day the workings of the mind and consciousness can be explained.
+
+## Asian Arts and Modern Science
+
+Many Asian arts (especially medicine) were considered ridiculous until recently. But now that for example the effectiveness of acupuncture has been proven, these arts are being embraced by an ever-widening crowd.
+
+But nothing has been clarified for a long time, the functioning of meridians and internal body dependencies is still unclear and results are based on speculation and assumptions.
+
+## Openness to All Aspects
+
+But today’s Ninja are not closed to new or old aspects. Ninja are not committed to any particular religion or creed, they incorporate those aspects of religion as working principles into their creed that have value to them.
+
+It is therefore important to understand that all aspects – be it religious or philosophical – are only meant to be suggestions for Ninja. It was by no means _mandatory_, nor should it be today, to have certain beliefs to call oneself a Ninja.
+
+Not a _kamiza_ (shrine) in the Dōjō makes the Ninja, but only his spirit and his physical abilities, be it Christian, Buddhist, Jewish, Muslim, Hindu, or completely different.
+
+## Philosophy and Religion as Ethical Foundations
+
+But what should be clear for sure is that a Ninja without any philosophical or religious basis is a disgrace to all. Anyone who sets their goal solely on physical development will fail. Anyone proud of being able to smash boards or defeat opponents in tournaments has chosen the wrong art in Bujinkan Budō Taijutsu or should never choose this art. Kickboxing, karate, or even better boxing is my recommendation.
+
+Also, I want to note that otherwise, he will never exceed a certain level in the Bujinkan (4th _dan_).
+
+## Origin of the Mikkyō in India
+
+The _mikkyō_ draws its teachings from esoteric, tantric currents that have their origin in India.
+
+These teachings, which originally come from Hinduism, were incorporated into esoteric Buddhism Vajrayana as tantra. This movement arose from the Mahayana and is practiced today primarily in Tibet.
+
+## Japanese Monks in China
+
+In the Heian period, the monks Saichō (Dengyō Daishi) and Kūkai (Kōbō Daishi) were sent to China by Emperor Kammu to improve the religious situation in Japan through the study of Buddhism. They brought the basics of _mikkyō_ to Japan when they returned.
+
+The monk Kūkai studied Mi zong in China and upon his return in 816 he founded the Kongobuji Monastery on Mount Koya (near Osaka), the headquarters of the Shingon sect, an esoteric _mikkyō_ Buddhist sect. He combined Shintō and Buddhism in his teaching.
+
+## Shingon
+
+In the Shingon, special importance is given to the _sanmitsu_ (The Three Secrets). Thought, word, and deed can lead everyone to Buddhahood. The main feature of this sect is the realization of a harmonious relationship of the five elements.
+
+The second monk, Saichō, studied tian tai, a branch of tantra. After his return, he founded Enryakuji Monastery on Mount Hiei zan for his Tendai sect. This monastery became the most powerful in Japan. At times, 40,000 monks and _sōhei_ were under the protection of the imperial house. However, in the course of his campaign against the _ikkō-ikki_ (rebel peasant warriors), _sōhei_ (Buddhist warrior monks), and Ninja, the monastery of Oda Nobunaga was burned down. Three major streams emerged from this destruction: Sammon, Jimon, and Shinsei.
+
+## Tendai
+
+The most important teaching in Tendai is to follow the three precepts: _Avoid evil wherever it appears, do good wherever possible, and respect all living beings_.
+
+In the countries of origin, the foundations of _mikkyō_ became a religion in the following centuries. A large number of gods were added and worshiped.
+
+However, the Ninja used the _mikkyō_ to enhance their skills and powers. _Mikkyō_ is not just a religion, but working principles of the laws of the universe.

+
+## Martial Arts After World War II
+
+After World War II, all martial arts were banned in Japan by the Americans. But the Ninjutsu survived. The teachings of the Ninja were passed on in secret by a small group of inconspicuous, interested men. Many of the Ryū died out because the last grandmaster had no descendants to pass on his tradition. Therefore, before dying, many destroyed the ancient scrolls and manuscripts.
+
+Due to the peaceful times, many martial arts have undergone a transformation. Many martial arts were spiritualized, and **jutsu** (art) became **dō** (way, path, principle).
+
+## Ishitani Takakage Matsutaro
+
+But not all masters accepted this change. Some longed to go back to the days when real martial arts were taught.
+
+One of these masters was Ishitani Takakage Matsutaro, a _chūnin_ Ninja of the Iga-Ryū clan. He was the 26th grandmaster of the Kukishinden-Ryū-_happohiken_. He opposed this innovation and despised the demotion of the arts to sports or Zen movements.
+
+Resigned and dejected, without a student and without a Dōjō, the master wanted to spend the rest of his life in anachronism. He considered destroying his secret scrolls and weapons before he died, lest the techniques fall into the wrong hands.
+
+Because Ishitani sought secrecy, he took a night watch job at the Takamatsu family’s match factory in Kobe. He met the family’s young son, Takamatsu Toshitsugu. In a roundabout way, he learned that this young man was a student of the Koto-Ryū _koppojutsu_ and the Shinden-fudo-Ryū _daken taijutsu_. Takamatsu had learned this art from his grandfather, Toda Shinryuken Masamitsu.
+
+## Ishitani Trains Takamatsu
+
+Ishitani offered this young man to initiate him into the mysteries of the Shinden-Ryū. Takamatsu enthusiastically accepted this offer and now studied under his new master Shinden-Ryū.
+
+Ishitani first showed him the eight parts of the _happo_ method. Next, he taught his student the _hiken_ method, secret sword techniques. Training is done with the sword, the short sword, and the _jutte_.
+
+Toshitsugu trained hard and after the death of his teacher became the 27th grandmaster of the Kukishinden-Ryū.
+
+## Toda Shinryuken Masamitsu
+
+During this time, Takamatsu was also taught the art by his grandmaster Toda Shindenryuken Masamitsu, 32nd grandmaster of the Togakure-Ryū. Toda was the swordsman of the Tokugawa government at the time, teaching the shogun’s Samurai the art of swordsmanship.
+
+Having been found unfit for military service at the age of 21 due to a ruptured eardrum – an injury sustained in one of the countless fights of his youth – Takamatsu decided to go to China.
+
+## Takamatsu Toshitsugu Goes to China
+
+Thoughts of a career in the match factory faded in the face of the adventures that awaited him in China. He believed China offered him better opportunities than Japan, which was in transition. He traversed China and found numerous opportunities to use his martial arts in real life against a variety of opponents, often protecting his life.
+
+The Chinese boxers he trained with gave him the nickname **Mongolian Tiger**.
+
+After these years of wandering, he returned to his native country of Japan to live in the mountains. He sought the solitude of these mountains in order to complete himself and become a _mikkyō_ priest of the Tendai at the age of 30 on Mount Hiei near Kyōto. With this knowledge, he penetrated deeper into the philosophy of the Ninja and their esoteric secrets. Armed like this, he finally made his way home to finally become the 33rd grandmaster of Togakure-Ryū-Ninjutsu.
+
+## Hatsumi Masaaki
+
+Hatsumi Masaaki began his martial arts training at the age of seven. First practicing with his father’s _bokutō_, he then dabbled in all of the popular Japanese martial arts during World War II, earning master’s degrees in karate, aikido, and judo. Martial arts and theater were his main interests. After the Second World War, however, he was horrified to discover how quickly and eagerly the American occupying forces learned the various judo techniques. Americans used their large size and natural athletic ability to learn in months what it took the Japanese years to learn. He wondered what was the point of training a system whose results others could surpass with the help of their physical strength alone. There had to be a true martial art somewhere that gave you the power to emerge victorious from any situation, Hatsumi thought.
+
+## Takamatsu Trains Hatsumi
+
+His _kobudō_ trainer finally told him about a teacher named Takamatsu Toshitsugu from the town of Kashiwabara in the west of the Iga area. Hoping at last to find a master who could teach him a living art of war rather than a physical exercise sport or a rigid system of inanimate _kata_, young Hatsumi wandered across Honshū Island in search of the teacher he was looking for had looked in vain up to this point.
+
+Takamatsu, the battle-hardened veteran, was well into his sixties when he first met the young man who would become his spiritual successor and next Ninjutsu grandmaster.
+
+For years, Hatsumi Masaaki tormented himself through rigorous training under the guidance of the Ninja grandmaster with the kind heart and hands of a tiger. Eventually, he inherited the title of Grandmaster of the Nine Ninjutsu-Ryū, embodied by his teacher Takamatsu Toshitsugu.

+---
+
+## Mochizuki Chiyome
+
+Chiyome was the wife of Mochizuki Moritoki, who was killed in the Battle of Kawanakajima in September 1561. Chiyome’s husband Moritoki was the ruler of Mochizuki Castle in Kitasaku Province in Nagano, and his family tree included Kōga Ninja.
+
+After the death of her husband, Chiyome retired to an old house in Nezu village in Nagano Shinshu’s Chiisagata province. She was asked to become the leader of the Miko (female Shintō shrine members) spy ring that operated in the Kai and Shinano areas. Chiyome gathered orphaned and runaway girls from various areas around her and trained them as Miko virgins and also as _kunoichi_ (female Ninja) Ninja agents for the Takeda family. The _kunoichi_ _jōnin_ (head of a Ninja Ryū) evaluated the talents, traits, and character of her girls in order to use them in the right place.
+
+## Fuma Kotaro
+
+Born in Sagami Prefecture, Kotaru was a fifth-generation _jōnin_ of Fuma-Ryū-Ninjutsu. He and his 200 retainers, called _rappa_ or _suppa_ (battle interrupters), worked as a guerrilla gang in support of the Hōjō family of Odawara. Fuma Kotaro’s most famous battle took place in March 1581, when the large forces of Takeda Shingen’s son Katsuyori attacked the Hōjō fortress. Takeda built his fortress at Ukishimagahara, and the Hōjō established their camp opposite, on the other side of the Osegawa River. The Fuma groups crossed the river and attacked the Takeda forces several times during the night, throwing the Takeda camp into chaos and disorder with their Ninja tactics.
+
+The story of the battle is described in the Hōjō Godaiki volume. By the time of the Tokugawa*bakufu*, the Fuma group was nothing more than a band of pirates roaming the inner seas.
+
+## Saiga Magoichi
+
+Born with the surname Suzuki, Magonichi was the leader of the Kishu Saiga Ninja group. A master of Tsuda-Ryū and Saiga-Ryū, with skills in explosives and firearms, he established his headquarters on the Saiga headland, recruiting his men from the _ji_ Samurai (local Samurai) from around Saiga Castle. They had 2000 rifles, a large collection at the time, and they had many good snipers. Because of this, they received a lot of support and goodwill from the regional rulers.
+
+Magoichi was involved in the battle of Naniwa Kanzakigawa alleys, in which Oda Nobunaga, the archrival of all Ninja also participated. Saiga Magoichi developed the tactic _shaki no jutsu_ (flag throwing) to win the battle. The Saiga group left their own flags behind and took their new position with fake flags of Nobunaga. Nobunaga’s troops saw them as allies. In those days, such tactics were considered scandalous and cowardly. But the Ninja were forbidden to fight anyway, so they could use any tactic. Magoichi’s strategy was surprising attacks combined with highly effective firearm attacks.
+
+A devout Buddhist, Saiga Magoichi continued his fight against Oda Nobunaga, the oppressor of Buddhism, until his death.
+
+## Suginobo Minsan
+
+Born Tsuda Minsan Kanmotsu, he took the monk name Suginobo Minsan. Legends say that he was the founder of the Negoro Ryū and was a talented firearms expert.
+
+Minsan’s brother was also a famous figure in the history of the introduction of firearms in the late 15th century. Minsan had heard rumors of a firearms demonstration in Tanegashima and traveled to the place. Suginobo Minsan was shown a _koshizashi_ (hip-held cannon), which he took to the blacksmith to have a copy made for him. Thereafter, the _sōhei_ (Buddhist fighting monks) prided themselves on their shooting skills and were known as capable marksmen.
+
+In March 1585, Toyotomi Hideyoshi attacked the Negoro Temple with 25,000 men because he had been defeated by the Negoro group the previous year. Minsan fought bravely, but he had to fight Mashita Nagamori, who defeated and killed him.
+
+## Sugitani Zenjubo
+
+Zenjubo was the eldest son of Sugitani Yototsugu, who was the _jōnin_ of the 53 Kōga Ninja families. Zenjubo was talented in the use of firearms and was recruited by Rokkaku Takayori as a sniper against Oda Nobunaga. On May 19, 1570, Zenjubo lay waiting to kill Nobunaga with two bullets, but the bullets only hit his shoulder butt and did not wound the cruel general. Sugitani Zenjubo then fled to the mountains of Omi Prefecture to hide.
+
+After four years of running away from his enemy, he was finally caught. Nobunaga tortured Zenjubo until he admitted and revealed the assassination. After that, the Kōga Ninja was tortured to death for six days.
+
+## Kato Danzo
+
+It is believed that Kato was a Ninja of Iga-Ryū because his name appears in the book Omikoku Yoshiryaku (Short History of Omi Province). There is a famous theory that he was born in Ibaraki Prefecture. Danzo’s nickname as a Ninja was Tobikato, or _Jumping Kato_ because he is believed to be a master in the Ninjutsu jumping techniques.
+
+In order to obtain a high position in the troop of the warlord Uesugi Kenshin, he appeared to Kenshin and demonstrated his _genjutsu_ art of illusion. Kenshin wanted to test him further, so Kato used his skills of invisibility and secretly entered a castle of Kenshin’s best general and stole a valuable scroll and a maid. When Uesugi still refused to hire him, he offered his services to rival Takeda Shingen. But Takeda also refused to hire him because he suspected he was a double agent of Uesugi. It is said that Takeda ordered his henchman Tsuchiya Heihachiro to kill Kato and solve the problem.
+
+## Kido Yazaemon
+
+In the fall of 1579, this Iga-Ryū Ninja and firearms expert attempted a clandestine assassination of Oda Nobunaga, the enemy of all Ninja. The assassination failed, but it was mentioned in the book Iranki on the conquest of Iga.
+
+## Igasaki Dojun
+
+Although the dates of Dojun’s birth and death are uncertain, it is known that he was born in Tateoka in Iga Province, so people called him Tateoka no Dojun. Igasaki Dojun is said to have been the founder of the 49 Ninjutsu Ryū of Iga, and his stories are recorded in the first volume of the Bansenshūkai.
+
+Rokkaku Yoshitaka, from Sasaki in the Omi region, used Dojun’s help to defeat Dodo, who had betrayed Rokkaku. Dojun took 44 Iga Ninja and 4 Koga Ninja with him to give Rokkaku victory. It is said that to enter the fortress, Dojun and his men used paper lanterns painted with the enemies’ family crests, and also used _bakemonojutsu_ (spirit arts).
+
+## Kumawaka
+
+Born in the Chiisagata Prefecture of Shinshu, Kumawaka (young bear) is said to have been a _genin_ (performing Ninja) of the Kōga-Ryū, allied with Takeda Shingen. The Takeda family had a force of 70 _suppa_ (Ninja guerrillas), and 30 of them were assigned in groups of 10 to Takeda’s three generals. This allowed them to better gather intelligence in their target area.
+
+In the Battle of Wariga Toge (1561), Kumawaka’s general Idomi Toramasa divided his army in two but then realized that he had forgotten his battle banners. A master in the Ninjutsu sneaking and running techniques, Kumawaka ran all the way back to Kumawaka’s fortress to retrieve the flags, all in just four hours. In those four hours, he managed to get the flags out of the castle, even though the guards did not know him as one of their own. During the battle, Shingen’s precious book, the Kokin Wakashu was stolen, and Kumawaka was suspected. He found the real thief and returned Takeda’s book.
+
+## Ishikawa Goemon
+
+Although neither the Iga nor the Kōga families would call him one of their own because he used Ninjutsu to steal for himself, the list of historical Ninja would not be complete without him. There have been many theories as to where he was born, but no confirmed knowledge. Three famous theories say he was born in Kamamatsu in Enshu, Oshu’s Shirakawa, or Ishikawa village in Iga province.
+
+Originally he was a _genin_ of Iga-Ryū, but he was scalded to death in boiling oil on August 24, 1594. Although Ishikawa Goemon’s name does not appear in the Bansenshūkai, he often appears in the novellas and in the theater as the greatest thief of all time. Today Goemon is the hero in numerous manga films and is admired by many children and young people.

+
+The _shinobi shōzoku_ or _ninnikuyoroi_ was a Ninja suit, made of dark, coarse cloth (gray, dark blue, or black; white-gray in winter) and covering most of the body. In the dark, Ninja were able to blend into the shadows in this way.
+
+The suit was worn rarely because many jobs were better done in normal clothes that were less conspicuous. If a Ninja was caught in his suit, that was certain death. However, when a Ninja was caught as a fisherman or farmer, it was easier to find an explanation.
+
+According to the latest findings, the suit was by no means dark black, because a dark area is more noticeable at night than a dark gray area.
+
+Also, the mask we know today was probably rarely used because it impairs hearing, which was an important ability of the Ninja in the dark of night. Usually, only simple cloths were tied around the mouth area.
+
+In some battles where Ninja fought in battle gear, chain mail was used, worn under or over the _shinobi shōzoku_. The chain mail also covered the face and palms.

+
+The shoes with the separate toe and non-slip sole were worn because they allowed a secure footing, quiet movement, and better climbing. On ropes, the Ninja could move up quickly with the _tabi_. To do this, he simply wedged the rope between the separate toe of the shoe and _walked_ up the rope.
+
+## Geta
+
+{% figure "Geta" %}

+
+Also _yuki waraki_. Under the _tabi_, the Ninja mostly still wore straw sandals or wooden sandals – _geta_. Steel or wooden blades were fastened under them in winter to be able to walk safely on fresh snow or ice. This is how the Ninja practiced one of his most important skills, his sense of balance.
+
+## Hakama

+
+This handguard covered the outsides of the hands and the forearms. When you made fists, you couldn’t see parts of your arms in the dark.
+
+## Tenugui
+
+Also _hokamuri_ or _kaiki_. This approx. 80 cm long cloth could be tied to form a mask or rolled out on the floor so that the floorboards didn’t crack when sneaking, or it could be used to filter water in the dark if the Ninja couldn’t tell what the water looked like. Therefore, the cloth had bactericidal substances in the fibers.

+## The Eight Gates of the Ninja
+
+This means that many arts that claim to be Ninja arts are warrior Ryū and not Ninja arts.
+
+In the Bujinkan, 3 Ryūha are pure Ninja Ryū, the togakure Ryū ninpō, the gyokushin Ryū ninpō and the kumogakure Ryū ninpō.
+
+The other six Ryūha are warrior Ryū, which of course doesn’t mean they aren’t effective! Even before that, Ninja learned other Ryūha to improve their skills.
+
+So were many famous Ninja, for example Hattori Hanzo, respected warriors in their region who few knew were also Ninja.

+excerpt: "The basic idea of Ninjutsu is not assassinations and espionage, but the development of a free and just spirit. History has falsified the reputation of the Ninja, which continues into modern times and is also maintained by the media."

+
+## What Is Ninjutsu?
+
+The famous Ninja master Momochi Sandayu, who led the Iga-Ryū in the Middle Ages as one of the three great leaders, put it in a clear, unmistakable sentence like this:
+
+> Ninjutsu is not intended for the gratification of personal desires. The Ninja engages in his art because he is compelled to protect his country, leaders, or family. If you only practice Ninjutsu for the fulfillment of personal desires, your techniques will not benefit you.
+>
+> **Momochi Sandayu**
+
+## Explanation of the Characters
+
+The word describing the mysterious shadow warriors cannot be directly translated into non-Japanese languages.
+
+
+
+The _nin_ part of the word, which is also found in Ninja and Ninjutsu, is pronounced _shinobu_. It means
perseverance, perseverance and omission
all in one. _Nin_ has a dictionary meaning and can mean
stealth, secretiveness or concealment
. _Jutsu_ in Ninjutsu means
art
, _ja_ in Ninja means
person
.
+
+
+
+The character _nin_ consists of two other characters. The upper part of the character is _yaiba_, which means
blade
.
+
+
+
+And the bottom part is _kokoro_, which is the Japanese word for
heart
.
+
+
+
+The construction of the character indicates that the heart, or will, is directed in paths that bring mastery over the blade as a tool. In a broader sense it means being in control of one’s body, soul and sense of what is right and what is wrong.
+
+## A Historical Misunderstanding
+
+Arguably no art in the history of the earth has been so misunderstood as Ninjutsu. Little truth is to be found, and historians have to search long to find sources about Ninjustu that are not excessive propaganda, slander, or tall tales.
+
+All of this is hardly surprising, since the official historians of the time were always part of the military dictatorship. Therefore, the resistance of the families of Iga (central Japan region) or Kōga (central Japan region) provinces has always been disparagingly mentioned in history. They have been recorded in history as criminals, insurgents or assassins.
+
+## History Is Always Subjective
+
+A similar example of subjective historiography can be found also in the history of the United States.
+
+Little is written in the history books of the brutal murders of the continent’s indigenous people, of the Founding Fathers, most of whom were slave owners. Their reputation remains that of heroes, champions of freedom and progress. The actual victims, namely the Native Americans (and the people abducted from Africa), were rewritten by historians as perpetrators.
+
+These facts should not be disregarded when studying history books, because a story always sounds different depending on who wrote it.
+
+One can look at the case of the Ninja in a similar way to the example of the Christian church: This also does not exist on the basis of the priestly brutality of the hellish days of the Inquisition of the Middle Ages, but on the basic Jewish thought of a carpenter from Israel.
+
+Unfortunately, little has survived about the Ninja for posterity, and for many the Ninja will probably always be those hooded people who slit the throats of their enemies on moonless nights in black suits and face masks, brutal fighting techniques, murderous weapons and hidden tools.
+
+## Ninjutsu and Modern Media
+
+Unfortunately, the modern media and traditionalists of Asian combat have further tarnished Ninjutsu’s reputation.
+
+Numerous videos, comics and books by self-proclaimed Ninja flooded the market, and in the 1970s there was a real boom in Ninjutsu. Many climbed from tree to tree through the forests believing they were **true** Ninja.
+
+Thank God the hoped-for happened:
+
+> I hope that after this tide, those few who seek the true essence of Ninjutsu will stay behind and help restore the reputation of this ancient art.
+>
+> **Hatsumi Masaaki**
+
+The media gradually stopped promoting Ninja as an interesting subject and lost interest – even the _American Fighter_ series finally ended after five episodes.
+
+Today, those who want to preserve the true essence of Ninjutsu have united in Hatsumi Masaaki’s Bujinkan (Divine Warrior) Budō (Martial Art) Dōjō (Training Hall) and spread all over the world.

+
+## The 36 Military Strategies
+
+The Ninja had to have a good grounding in the 18 categories of martial arts (_bugei jūhappan_) and try to become a specialist in them. In addition, a Ninja had to learn another 18 categories of secret techniques (_Ninja jūhakkei_).
+
+The number 36 is special because it can be broken down into 3 and 6. Adding 3 and 6 gives 9. Multiplying 3 and 6 gives 18. Dividing 18 back into 1 and adding 8 gives 9 again. In martial arts, especially the Chinese, the number 9 is special. The number 9 is said to be perfect because 10 begins a new range of numbers (two digits).
+
+The _sanjūrokkei_ often varied, subject areas were dropped, others added. Of course, a Ninja not only learned the _ninpō sanjūrokkei_ but always tried to perfect himself in as many areas as possible.
+
+Of these 36 basic martial arts, 3 are of particular importance. _Taijutsu_ (unarmed combat), _bikenjutsu_ (sword fighting), and _bōjutsu_ (stick fighting). These 3 are also referred to as the _three pillars_ of the ninpō.
+
+Also of great importance is _seishin teki kyōyō_ (spiritual development). Without the spiritual and philosophical aspect, martial art degenerates into an empty shell with no value.

+
+## The Art of Hiding
+
+The art of hiding, concealing, making oneself invisible and camouflage is also referred to as _inton_ or _inpō_. Hiding is probably the most effective method of self-protection. One can observe from relative safety or wait until a certain point in time has come. The art of rendering invisible can be divided into three different areas:
+
+- Avoiding the reflection of light, avoiding noise and smells
+- Paralyze the opponent’s ability to observe and hear
+- Dress up and acting
+
+To understand the art of hiding, one must first hone one’s senses and try and recognize the effects of color, shape, sound, distance, and smell. Only then is one able to understand the connections and avoid these anomalies.
+
+## The Five Methods of Inpō
+
+Based on the foundation of the _godai_, a principle was developed that Ninja could use in concealment. These aspects are very similar to the _goton pō_, and in principle, it is not possible to strictly separate the many areas, since each area is directly related to another area.
+
+### Chi – Method of the Earth
+
+- Exploitation of land
+- Hide in burrows, hollows, crevices, or behind stones (_uzura gakure no jutsu_, Engl.
The art of hiding like a quail
)
+- Use of vegetation for camouflage
+
+### Sui – Method of the Water
+
+- Hide in or underwater
+- Use of artificial reed islands for hiding
+
+### Ka – Method of the Fire
+
+- Camouflage using light, shadow, and sound
+- Silent movement
+- Attention to shadows and reflections
+- Use of dusk, fog, or rain for camouflage
+
+### Fu – Method of the Air
+
+- Conceal in an elevated position, such as on trees or poles
+- Hide in treetops
+- Conceal on gables
+
+### Kū – Method of the Emptiness
+
+- Methods of camouflage when natural resources are not available
+- Roll up to appear like a boulder
+- Motionless stand in the field to appear as a scarecrow
+- Conceal in sacks, baskets, barrels, and other containers (_shiba gakure no jutsu_)
+- Hide under floors or in gaps
+
+## Basic Rules of Camouflage
+
+- Camouflage hides the body but does not protect against the effects of weapons and shells
+- Even in absolute darkness, that doesn’t automatically mean perfect safety. Technical aids such as residual light intensifiers, infrared and thermal imaging sensors could be used
+- If you are spotted by searchlights or flares, you should make yourself small and stop moving
+- Colors no longer exist in the dark, so it doesn’t matter whether you wear bright red or black. But you should opt for darker colors because of possible light radiation. An uneven pattern and matt fabrics are even preferable to a deep black
+- In the light darkness you will be recognized by fast, hectic movements. Therefore movements should be carried out slowly and smoothly. If quick movements are required, they should be done close to the ground and for short periods
+- If you have to move over wide areas, you should plan the route beforehand and always jump from cover to cover. Never walk in a straight line for long periods
+- Hollows and burrows should be exploited when observing
+- Fresh soil from an excavation should be covered or removed
+- In total darkness, the Ninja used a trick to get his bearings. He placed the _saya_ on the tip of his sword blade. To keep it from falling, he held the ribbon between his teeth. When he bumped into an opponent, he simply dropped the _saya_ and immediately had the sword in his hand, ready to strike. It also served as a probe, and with the dual-range (_saya_ and blade) he was always out of range of the object or person he sensed with that probe
+- Light sources should not be visible under any circumstances
+- Natural camouflage materials have to be replaced frequently, otherwise, they can become conspicuous due to withering or drying out
+- The camouflage must fit into the region, the natural direction and type of growth must be observed, i. H. Leaf undersides should face inward
+- Artificial camouflage can also be used, stripes, camouflage nets, and camouflage garlands have a camouflage effect similar to that of natural vegetation
+- If you camouflage your face and hands, you should pay attention to an irregular pattern
+- It is best to visit an area when it is already bright and to memorize the topographical conditions
+- Moonlit nights are particularly good for observation missions
+- Moonless nights are suitable for infiltration, exfiltration, or combat missions
+- Rain can help hide your sounds and limit your opponent’s vision. In addition, sentinels become less alert when it rains and spend less time outdoors
+- Traces should be avoided or removed if possible
+- Cast shadows from objects or people should be avoided
+- The eye takes a certain amount of time (up to 20 minutes) to adjust to the dark, but it only takes a few seconds to adjust to the light. It is therefore essential to avoid looking directly into white light. A red light should be used to find your way around on maps or with devices
+- It is best to always observe from a low position against the horizon
+- If you look hard at a point in the dark, target recognition is limited and a black point seems to dance in front of your eyes. Therefore, one should circle a target with one’s gaze
+- Objects appear to move when observed in the dark. They appear to change shape and color
+- When it’s dark, objects appear larger and distances appear longer. Suddenly flashing light appears closer
+- Be sure to protect your eyes when exposed to light, otherwise night vision will be lost
+- Movements across the opponent are particularly dangerous
+- Holding your hands in a funnel shape in front of your eyes improves your vision
+- When confronted directly with the opponent, his ability to observe can be reduced or prevented by smoke bombs, chemical gases, sprays, blinding powder, or intense flashes of light
+- In light winds in an open area, noise can be heard at the following distances:
+ - 70 m – footsteps of a person with boots on the grassy ground
+ - 100 m to 150 m – whispering
+ - 130 m – snapping of branches
+ - 150 m – footsteps of a man with boots on a dirt road
+ - 150 m – Conversation of several people without caution
+ - 300 m – Marching troops
+ - 600 m – Driving in poles
+ - 1000 m – hitting a stone with a spade
+ - 3000 m – engine and chain noise of vehicles
+- Putting the ear on the floor improves hearing ability
+- To be able to locate noises better, always turn your head in the direction of the noise, if necessary place your hands behind the ear cups for support
+- Especially noise should be avoided. Keep or avoid conversations at whisper levels. Better to use hand signals
+- You should pay attention to your body odor. While it is the least developed sense in humans, dogs can be in the company of guards. It is, therefore, best to approach against the wind

+---
+
+## Jonin
+
+The Ninja developed a special system to keep their organization secret. Three distinct ranks have been developed, each with its own specialty and responsibilities.
+
+At the head of a Ryū was a leader the head of the organization. The _jōnin_ controlled the activities and decided what his Ninja did and at what cost. In larger Ryū, the _jōnin_ was a wise man who was well informed about everything. He made his decisions based on a philosophical understanding of the totality of the universe. The true _jōnin_ was a champion of harmony, aiding the oppressed without expecting great honor or great opportunity on his side.
+
+He kept his vulnerability low by hiding his true identity from almost all of his agents. His agents were unable, even under the greatest torture, to reveal his identity or sell it to rivals.
+
+Likewise, the _jōnin_ could send different agents independently on the same mission to ensure success. By getting a picture of the situation from each of his agents, he was able to complete his complete picture.
+
+This system of invisibility is used by numerous criminal organizations today for very similar reasons.
+
+## Chunin
+
+A group of middlemen works for the _jōnin_. It was the task of these _chūnin_ to interpret the words of the _jōnin_ correctly and to have the orders carried out correctly. A _chūnin_ knew how to carry out an operation successfully, and to which agents he delegated the various tasks. He also guaranteed the anonymity and security of the _jōnin_.
+
+When a client wished to employ the services of a Ninja clan, he would send a messenger to an area where _chūnin_ were known to reside. This could be a remote area, or it could be fishing villages or entertainment districts. The _chūnin_ then contacted the messenger, each time making contact in a different disguise. The _chūnin_ informed the _jōnin_ of the commission. The latter then weighed up the motives and first had background information obtained before agreeing or refusing. But even the client did not usually trust the Ninja straight away but instead had a fictitious order carried out first. Because betrayal and intrigues were the order of the day at the time. There were some Ninja Ryū who were loyal to certain houses, others who supported the house that pursued their goals, and still other clans who accepted any commission if the fee was right. These minor clans, often acting without the foresight of a _jōnin_, contributed greatly to Ninjutsu’s bad reputation.
+
+As _officers_, the _chūnin_ rarely took an active part in an operation. Of course, her training included combat techniques and espionage techniques, but her specialties were strategy and effective leadership.
+
+## Genin
+
+The executive agents were called _genin_. It was their job to carry out the plans. It was the _genin_ around which all the fantastical legends were woven. They were the ones who ended up doing the murder, sabotaging the bridge, or opening the gates of a fortress to their own troops. They lived in constant danger of being discovered on their missions and had to survive on their own.
+
+They only had contact with the _chūnin_ and usually did not know the _jōnin_ so that his identity could be kept secret.
+
+When not on a mission, they lived with their families in small, secret villages nestled in mountainous and swampy areas that were difficult to access. They lived there and appeared to be farmers or fishermen. They trained in secret, and not even their neighbors knew about their deadly trade. Often two groups of _genin_ worked for the same _jōnin_ without knowing anything about it.

+
+## The Tengu as Ancestors of the Ninja
+
+
+
+Demons of the forest. _Tengu_ 👺 (Japanese
sky dog
, mythical creatures from Japanese history). Winged, long-nosed mythical creatures that lived hidden deep in the cursed forests of Japan.
+
+Frightened, the residents told each other stories about the Ninja. The _tengu_ would be their ancestors and would have taught them martial arts. Mages, sorcerers, demons. A Ninja is immortal, invulnerable, can walk through walls, fly, disappear whenever he pleases and nobody can defeat him.
+
+The shadow warriors of Japan _enjoyed_ their reputation because it gave them some privacy from the curious and protected their anonymity.
+
+And not infrequently a young Samurai who had to fight a Ninja for the first time died. And not because he could fight better, but because his fear paralyzed him and superstition manipulated him.
+
+## Origins in China
+
+
+
+There are still many uncertainties about the beginnings of Ninjutsu. The very first origins are most likely in mainland China. So the ideas were brought to Japan from China by refugees.
+
+The existence of Ninjutsu in Korea and China (_Lin Kuei Hing Su To_) speaks for this.
+
+{% productshelf %}
+{% product "081331951X", "The Art of War", "en" %}
+{% endproductshelf %}
+
+The 2000-year-old war classic **Sun Tzu**,
The Art of War (c. 400 to 320 BC) is probably one of the first works dealing with espionage. This script was brought to Japan around 600 AD and integrated into the early days of Ninjutsu. Furthermore, Indian and Tibetan influences have flowed into Ninjutsu (e.g. the _kuji in_, _mantra_, _mikkyō_, or _mandala_).
+
+## The First Shinobi
+
+The prince regent Shōtoku Taishi (572-622 AD) was the first to use agents to find out about the true background of controversial issues. Under his reign, the name Ninjutsu or _shinobi no jutsu_ also came about.
+
+One of Shōtoku’s generals, Otomo no Saijin, achieved some great victories through the use of scouts and the information they gleaned. Shōtoku Taishi then proclaimed this warrior _shinobi_, which means _to hide_ or _to camouflage_.
+
+Originally Ninjutsu was probably only pure scouting. During the Heian period (794-1192) it developed into a deadly art.
+
+## Ninjutsu and Buddhism
+
+After the death of Shōtoku, a cruel dispute broke out between Buddhists and Shintoists in Japan. Both teachings claimed to be the new state religion. This dispute ended in a civil war. A _yamabushi_ by the name of Enno no Gyōja went public and tried to restore order through a new branch of Buddhism, the _shugendō_. Religion was very popular with the people. Fearing that the _yamabushi_ would usurp state power, the nobility raised a large force against them.
+
+Faced with this superiority, the priests retreated to the mountains around Kyōto and continued their war according to Chinese military tactics.
+
+## The Warriors From the Mountains
+
+Incredible stories are told about the _yamabushi_ who have always eluded the troops during the years of persecution.
+
+They could walk over hot coals, dip their hands in boiling water without suffering burns, put out sudden conflagrations, boil cold water in seconds, or else bind the swords of their enemies so tightly in the _saya_ (scabbard) that no power could pull them out. This _shugendō_, the way of miraculous achievement through asceticism, protected the warrior monks from the troops.
+
+
+
+From them, the Ninja also learned to master the _mudra_ (finger signs), a series of 81 finger gestures that can control specific areas of the psyche. In this way, the Ninja have been able to control emotions such as fear, hunger, cold, and pain, sharpen their senses and concentrate. The _mudra_ originally come from India and mean _seal_ or _sign_. They are physical expressions of a certain state of consciousness.
+
+In Ninjutsu, however, only 9 gestures were used, which were called _kuji in_, the 9 basic gestures of the hand.
+
+In the Heian period (794-1185) _omyodō_ (divination and astrology) was introduced to Japan, which was another step forward for Ninjutsu.
+
+The _omyodō_ was an ancient comprehensive science composed of the elements of Chinese divination and astrology.
+
+## The Role of the Ninja in the Middle Ages
+
+By the Middle Ages, Ninjutsu was slowly evolving in a different direction. Rarer still did students learn the deep fundamentals of _shugendō_ and other sciences, for it often took a lifetime to become nearly perfect in any of these techniques.
+
+Many princes, such as the powerful Genji family (the name for the Minamoto) maintained close contact with the warriors of the mountains. And more often the services of the Ninja were in demand for smaller reconnaissance missions. At this point, no concept such as Ninja or Ninjutsu had emerged, it took some time before the members of these clans saw themselves as a Ninja.
+
+New aspects have been added to improve Ninjutsu and train agents faster. The older arts, which were difficult and laborious to learn, were slowly being replaced by physical and psychological feats, optical illusions, and sleight of hand.
+
+Refined techniques, efficient martial arts, sufficiently tested for their lethality, and body control made the Ninja a nearly invincible fighter whose reputation sowed fear and terror in the ranks of his enemies.
+
+It was not until the middle of the Heian period that Ninjutsu was firmly established.
+
+The Hattori family laid the foundation for their Iga Ninjutsu school in Iga Province.

+excerpt: "Mikkyo contains three factors known as ‘The Three Secrets’. These are thought, word and deed. They are represented by mandala, mantra and mudra."
+translationKey: "sanmitsuPage"

+ - philosophy
+ - religion
+---
+
+## Mandala
+
+Mandala means _nenriki_ in Japanese and is concentrated intention. The mandala symbolizes the will of the Ninja.
+
+In the _ninpō mikkyō_ there are two different ways of looking at the structure of the universe. Both are completely opposite, but only when both are practiced can insight be gained.
+
+One possibility is to look at the course of the universe from the inside, i. H. one concentrates on the physical phenomena and tries to gain an understanding from that point of view.
+
+### Taizokai Mandala
+
+{% figure "Taizokai Mandala" %}
+
+
+
+{% endfigure %}
+
+To comprehend the material world, the _world of breeding ground_, the Ninja can look at the Taizokai mandala and contemplate the meaning of the work of art.
+
+He will come to realize that everything exists within this one universe. All the galaxies, star clusters, star systems, stars, planets, animals, people, words, colors, shapes, and thoughts. Everything we accomplish during our lives influences this cycle and is recognized because it takes place in God. Conversely, God is also present in each of these things. In this way, we get a better view of larger perspectives and may find that all opposites and paradoxes find their place in this universe.
+
+The other way is to raise the mind above the universe, separate from _I_, and survey the whole universe. This is how one recognizes cosmic laws. One understands and comprehends the fine threads that are tied between all things in the universe, the dependencies among one another.
+
+### Kongokai Mandala
+
+{% figure "Kongokai Mandala" %}
+
+
+
+{% endfigure %}
+
+To comprehend the spirit world, the _world of diamond_, the Ninja can look at the Kongokai mandala. The diamond in this case represents hardness, clarity, and pure knowledge, the ultimate truth.
+
+The Ninja will come to realize that this _reality_ is only the subjective view of what is real. Everything around us has only the form that our cosmic laws give it and shape our consciousness. Leaving behind the material world and experiencing the cosmic laws, one attains _kanjinkaname_, the _Mind, and Eyes of God_. In this way, one can look down on the earth from a higher, enlightened level.
+
+However, you must practice both ways of looking at things, because otherwise, an imbalance will arise. So the art of Ninjutsu can degenerate into a purely mechanical and technical combat system without spirit, or you lose touch with reality, become unworldly, and feel elevated and above everything.
+
+{% youtube "yHcntfFN9FY" %}
+
+## Mantra
+
+Mantra means _jumon_ in Japanese and is the _charged_ word. The mantra symbolizes the intellect. Words and actions alone are nothing. Only when the germinating thought behind it can be recognized as the motive are they effective. The _charged word_ is the continuation of thought as a word. The words used by the Ninja are mostly still in their original language or, if translated, without a specific meaning. In tantra, it is believed that certain sounds can influence the process of the universe. The exact functionality has not yet been scientifically clarified, but many of the mantras are very pure in their vibration rates and harmonize with the frequencies of the physical realities.
+
+A simple example is the primal sound _Ohm_ when you first open your mouth wide and make an _ah_ sound. Without change, the mouth is closed, resulting in an _oh_ sound and then an _m_ sound. Finally, the tongue is pressed against the incisors, resulting in an _n_ sound. So the sound sequence is _Ah-oh-mm-nn_. This sound closely resembles the Christian prayer sound _Ahmen_. However, these exercises are very special, so you can learn them on your own. Many aspects such as pitch, breathing rhythm, and voice quality contribute to the result. One should consult a qualified master if one is interested in mantras.
+
+## Mudra
+
+Mudra means _ketsuin_ in Japanese and is the hand position. The mudra symbolizes physical action.
+
+The _kuji in_ hand signs are the third secret of _sanmitsu_. Its origin can be found in the countless hand positions from India.
+
+As with acupuncture, certain meridians are likely to be stimulated with these hand positions. Many ends or turning points should be found especially in the hands. Only nine of these hand positions have been transferred to Ninjutsu. These are: _rin_ (臨), _pyō_ (兵), _tō_ (闘), _sha_ (者), _kai_ (皆), _jin_ (陣), _retsu_ (列), _zai_ (在), _zen_ (前). These are the mantras for each hand position. Each of these hand positions symbolizes a goal worth striving for, which turns from thought to word to action. The whole organism is brought into this state of harmony and the Ninja feels as if the result has already been achieved, it is just waiting for it to show up on the physical plane.
+
+These hand positions have no effect if you just fold them like that. It takes many years of intensive training with an experienced master to feel the effects. Not like the Hollywood movies would have us believe: when you’re hurt, you just sit in a corner, tie your hands in a knot, and the healing is complete.
+
+## Kuji kiri
+
+The _kuji kiri_ does not belong to the _sanmitsu_ but is mentioned here for information. It is very closely related to _kuji in_, however, most people confuse the two. Both were probably introduced to Japan with Buddhism.
+
+The _kuji kiri_ or _kuji goshin hō_ is said to originate from the god-like warrior guard Marishiten. This esoteric formula of power is used to overcome evil, illusion, ignorance, or weakness and to strengthen the Ninja.
+
+The Ninja mimics the flaming sword of the _fudōmyō_, the fearsome mythical protector of the will, law, and integrity of the universe.
+
+{% figure "Kuji goshin hō" %}
+
+
+
+{% endfigure %}
+
+The right, positive, and left, negative hands are brought together in front of the chest to represent the sword. An incantation is repeated several times, and then the Ninja steps forward and draws alternate horizontal and vertical cuts in the air with his symbolic sword. The spiritual blade is moved alternately from left to right and up and down until the nine cuts form a grid. The Ninja speaks the nine syllables of _kuji goshin hō_. A further tenth syllable can be added at will before the lattice is severed with a handshake and the symbolic sword is inserted back into the _saya_.
+
+Fishermen liked to add the syllable for water as the tenth sign in the lattice, which they drew on paper for protection and safe travel. Ninja could for example add the symbol for a demon to scare and terrify enemies. As with the _kuji in_, these techniques are included for information only. Without the right teacher, long practice, the right breathing rhythm, and mental focus, practicing _kuji kiri_ has no effect.

+priority: 610

+author: "Stefan Imhoff"
+excerpt: "With the method of Shichi hō de, the seven ways of walking, one is seen by the opponent, but not perceived. The filter that protects a normal person from sensory overload can be exploited by a Ninja to blend into the crowd."
+translationKey: "shichiHoDePage"

+---
+
+## Immersion Through Sensory Overload
+
+Just as playing the flute is easy to hear on its own, so when the flute sounds in a concert, it disappears in the mass of tones and is only rarely heard.
+
+Another good example is a beautiful oil painting in a gallery. If it hangs alone on a wall, we perceive it, if it hangs together with many others in a hall, it gets lost in the crowd.
+
+In everyday life, we meet countless people, most of whom are only noticed briefly or not at all. The larger the city you are in, the more this effect comes into play. In rural areas, you may immediately attract attention as a stranger, while in big cities you can move around unmolested.
+
+Our consciousness filters out everything that is not necessary for our survival. This means that only people we know, people with an unusual stature, special appearance, or physical characteristics penetrate our consciousness. The other people are mostly noticed, maybe you even make eye contact in passing, but after a few moments, most of them have disappeared from our consciousness.
+
+In the Middle Ages, this meant that the Ninja spent most of his mission in natural disguise. He only carried out a very small proportion of his orders in the typical black battle dress.
+
+## The Seven Disguises in the Middle Ages
+
+The medieval system of _shichi hō de_ consisted of seven different disguises and professions commonly encountered at the time. However, it is only a conceptual model, a Ninja was by no means limited to these seven disguises, he always adapted the disguise to the environment and the benefit. He could also act as a doctor, a traveler, a farmer, a soldier, a fisherman, or in some other role.
+
+- Akindo (Merchant)
+- Hokashi (Musician)
+- Komusō (Wandering Priest)
+- Rōnin (Masterless Samurai)
+- Sarugaku (Entertainer)
+- Shukke (Buddhist Monk)
+- Yamabushi (Warlike Mountain Ascetic)
+
+The _shichi hō de_ consists of two important components. On the one hand from the _hensō jutsu_ (the art of disguise), and on the other hand from the _gisō jutsu_ (the art of thinking oneself into others).
+
+In _hensō jutsu_ the Ninja learned how to put on the disguise and adapt it to his own body. In _gisō jutsu_ one learned how to imitate a person, what characteristics and qualities one had to internalize.
+
+## A Modern Adaptation
+
+Of course, today it is no longer possible for a Samurai to go through his area of operations unobtrusively. But the methods of Ninjutsu are timeless, they just need to be adjusted from time to time. Stephen K. Hayes has developed a more recent version of the _shichi hō de_:
+
+### Scholastic
+
+This category includes students, teachers, scientists, technical specialists, artists, and idealists. You have to familiarize yourself with the relevant university, school, or institution. Usually, you also have to have a specialist area that you should master. As an artist, you also have to have works or work to show for yourself and be able to show off your talent. As an idealist, you also have to identify with the idea you represent.
+
+### Business People
+
+This category includes salespeople, traders, clerks, secretaries, accountants, and business owners. You should be able to demonstrate basic knowledge of your field. Appearance should be similar to that of a business person, experience and knowledge of the industry should be noted. Necessary business papers such as business cards, annual reports, etc. should be forged.
+
+### Country People
+
+Farmers, ranchers, foresters, lumberjacks, migrant workers, and all people normally found in rural areas fall into this category. Of course, you have to be familiar with your field and know about cows, agriculture, or forestry. You should also be able to handle the necessary equipment, such as tractors, agricultural machinery, or hunting weapons. Of course, you also have to be able to show the necessary documents, such as a hunting or fishing license. This role is probably the hardest because being a stranger in rural areas immediately attracts attention and scrutinizes you.
+
+### Clergy
+
+All persons of religious life, such as priests, rabbis, preachers, missionaries, sect leaders, and possibly also social workers belong to this category. If one claims to belong to one of these groups, one must be very familiar with the rules, regulations, and taboos of the religion. Certain bed rules, dietary regulations, or ways of acting must be strictly observed for the role.
+
+### Representatives of Public Life
+
+Entertainers, actors, musicians, elite athletes, politicians, reporters, models, and others associated with the yellow press can all be included in this category. One should of course have a certain skill in his field and have the right demeanor. Autograph cards and image material, party folders, etc. should be available.
+
+### Laborer/Craftsman
+
+All people who involve physical effort in their job, such as construction workers, painters, gardeners, truck drivers, plumbers belong to this category. Of course, you should be able to show that you have the necessary tools and expertise. You also have to consider that you may be able to tell from physical features whether you are doing physical work.
+
+### Uniformed
+
+This area includes repair crews, water company or electric company employees, prison guards, police officers, nurses, military, security guards, and guards. In principle, you can probably get the furthest with this camouflage and may even be allowed to enter security-relevant areas. It goes without saying that you have to be able to show the necessary papers and permits.
+
+Of course, the possibilities are far from exhausted with these professional groups. A contemporary Ninja does not feel restricted by any limitation and will let his imagination run wild at will.
+
+## Adaptation to the Disguise
+
+The goal should always be not to choose the role that is easiest to portray but to choose the one that brings the Ninja closest to his goal. Under certain circumstances, the path is not easy, it can also happen that the Ninja first has to familiarize himself with a team of workers for a while before he reaches his destination or his target person.
+
+### Type
+
+The person you want to embody must also match your type. You can’t play a construction worker as a small, slim person with soft skin without putting yourself at risk. As a young person, the role of a company boss or a dignitary is not taken away from you. On the other hand, an older person is not believed to be a student.
+
+### Hair and Body Shape
+
+The easiest way is to change the hairstyle and hair color. Changing body shape is far more difficult, and requires a lot of time or costly costuming. Posture, gait, and behavior can be adjusted through persistent practice. Disguise, makeup, and costumes can be easily customized.
+
+### Knowledge and Skills
+
+It is much more difficult for a Ninja to acquire the necessary specialist knowledge of the professional group. Of course, you can prepare yourself for a job through books, at universities, or in courses, but it can happen that you are forced to prove your specialist knowledge. Depending on the professional group, this can prove to be differently difficult.
+
+### Language
+
+Language is another difficult part of the transformation. An experienced Ninja speaks as little as possible in order not to reveal himself. Of course, being overly reserved in certain professions can be very suspicious, but silence is usually safer because you can’t get caught up in any question-and-answer conversations. It is imperative that you become familiar with correct pronunciation, speech quality, and accent. The necessary technical language, idioms, and colloquialisms must absolutely fit the role. When you are in a foreign country, there is also the barrier of the foreign language, because if you cannot speak without an accent, you immediately stand out as a foreigner.
+
+### Operation Area
+
+It is also important to familiarize yourself with the geography of the area of operation. You should know escape routes and be able to find your way around your workplace.
+
+### Psyche
+
+If you want to take on the role of another person, you have to internalize their psychology as well. You may have to say things you hate or behave in a way you normally hate. Without the necessary acted conviction, you won’t be able to play the role convincingly enough.
+
+It should also be borne in mind that a distinction must be made between private and professional in most occupational groups. Cops don’t always talk about crime and fighting it.
+
+In _shichi hō de_ you have to focus your whole mind on the role you want to play and become a different person at times. But one must not lose oneself in the new role so that a return to the old _I_ is no longer possible or is even rejected. This requires a very strong personality.

+
+## The School of the Unmoved Heart
+
+The Shinden-fudo-Ryū was founded by Genpachiro Temeyoshi in the mid-12th century. One can trace the trail back to the _koshi jutsu_ introduced by Izumo Kanja Yoshitero. It is not clear if he is the same person as the Kukishinden-Ryū’s Izumo.
+
+The basis of the teaching is the knowledge of nature. Training begins by using nature to strengthen your body. First the legs and hips, then the fists.
+
+In this Ryū, you didn’t build a Dōjō or tinker with training tools but stayed in nature during training. They practiced hitting and breaking on trees. Then you practiced hardening your forehead against trees. Kicking the unique kicks of the Shinden-fudo-Ryū was practiced in the bamboo forests. People practiced tearing the bark off trees, which is very similar to tearing the skin off.
+
+This school specializes in jūjutsu and _iainuki_ (swift swords). The _katana_ in the Shinden-fudo-Ryū is much longer and heavier than a normal _katana_, making it very difficult to draw such a sword. But later you were able to draw normal swords much faster.
+
+Izumo is said to have been taught how to use the _yari_ by _tengū_, and these techniques remain a secret to this day. Various _yari_ were used in this Ryū, the _ono_ (war ax), _otsuchi_ (war hammer), and the _naginata_.
+
+The _hōjō jutsu_ (The Art of Binding) was also used in this Ryū. You could smash through Samurai armor with the big war axes, and smash through doors and barricades with the war hammer. The _naginata_ was primarily used by foot soldiers against horsemen.
+
+There are no _kamae_ in Shinden-fudo, the _shizen no kamae_ is the identifying mark of this Ryū.
+
+It was extremely important to always land on your feet when thrown because in Shinden-fudo-Ryū you always wore the _daishō_. A fall with swords was very dangerous and could even be fatal with wooden swords.
+
+There is a saying that to be able to learn more than the basic techniques, you have to be able to perform a one-finger flip.
+
+Takamatsu was only thrown around the first year when he learned the Shinden-fudo-Ryū from his grandfather Toda before he was allowed to learn a _kata_ for the first time.

+
+## Techniques in Detail
+
+### Nuki ashi – Silent Step
+
+This technique allows the Ninja to move silently over wooden planks or straw mats. He has total control over his body weight. From a low position, balance and body weight are slowly transferred to the front leg until all weight is on the leg. Then the back leg is pulled. The ankles almost touch. The weight is slowly transferred to the foot. This way the Ninja can withdraw the foot as soon as he hears a sound.

+
+{% figure "Nuki ashi – Silent Step 3" %}
+
+
+
+{% endfigure %}
+
+### Chōkyori kyōsō – Long-Distance Running
+
+This running method was the basic method of all Ninja, but it was adapted by each individual runner to their own build, stride length, and arm position.
+
+The runner keeps the torso upright, the head straight, and fixes on a point about 10 meters in front. The foot is placed with the outer edge of the heel and rolled forward. An important factor in running long distances is breathing. To do this, the Ninja used diaphragmatic breathing and maintained a constant pace throughout the course.
+
+Some stories say Ninja were able to travel the 560 km between Edo (Tōkyō) and Osaka in three days.
+
+### Ko ashi – Small Step
+
+{% figure "Ko ashi – Small Step" %}
+
+
+
+{% endfigure %}
+
+This small, stabbing step is used when one needs to walk through shallow water or leaves without making a sound. From a hip-dropped position with the weight on the front foot, the Ninja pulls the back foot behind and pulls it up. Then he holds it over the spot where he wants to lower his foot, he carefully touches the spot with the tip of his foot, when the spot is safe he lowers his heel. This pose resembles a crane making its way through the wilderness.
+
+### Yoko aruki – Lateral Walking
+
+This technique is used to move quietly in the shadows of buildings or corridors. The hips are aligned laterally to the target of the movement. Weight is shifted to the front foot and the back foot is placed in front of the front foot. The body weight is shifted and the back foot is placed forward in its new position. The movement is performed smoothly and smoothly, resembling a crab moving sideways along the beach.
+
+Sometimes a standing movement is no longer possible, then the Ninja has to crawl.

+
+### Heipo – The Way of the Salamander
+
+{% figure "Heipo – The Way of the Salamander" %}
+
+
+
+{% endfigure %}
+
+This technique allows the Ninja to move completely silently over a short distance. The Ninja lies flat on the ground and moves only on the palms and toes. Instead of the palms, this technique can also be performed on the fingers.
+
+The arms must be as close to the body as possible to save energy. The further the arms are spread from the body, the more strength is required.
+
+The body weight rests on the right palm and the tip of the right toe. This happens with locomotion in rhythmic alternation, similar to a salamander.
+
+Because the Ninja only ever has four points of contact with the ground, noise can be easily avoided.
+
+## Training
+
+To start training silent movement, first, observe nature and how noise is made. One should take a lot of time to observe which sounds work in which ways, which helps to mask sounds, how one’s own movements and the movements of others work. Noises (such as door noises, foot noises, wind, etc.) that are otherwise hidden by the subconscious should also be observed during the exercise.
+
+Now that you know how noise is made, just make sure you don’t make it. After that, training begins on boards, leaves, grass, gravel, etc.
+
+According to Stephen K. Hayes, laying out a few layers of wet newspaper on the floor is particularly effective. If you didn’t walk properly, you can tell by the creases and folds in the newspaper surface.
+
+The following list may help you learn the techniques:
+
+- To maintain control of balance, the bodyweight is lowered while the knees are slightly bent.
+- Do not forget to breathe during the movement. Breath-holding causes unnecessary muscle tension, which affects balance.
+- Keep an eye on the entire movement while moving. Don’t just look at your feet and no longer notice other people or buildings.
+- Use all joints for movement. Don’t stiffen your knees and swing the whole leg from the hip as a solid object!
+- Throughout the movement, keep your weight on the foot that is on the ground. Avoid putting weight on both feet.
+- Keep your arms at different heights next to your body so that a disability can be identified immediately.
+- If there is too much noise, take a break and listen to your surroundings. Then lower your hips a little lower, relax completely, breathe in deeply and breathe out slowly during the movement.
+- Have as much patience as possible. If speed is not essential, take as much time as necessary. Inattention results in violent movements that are easy to hear.
+- Always adapt the movements to the environment. In some areas, total silence may even be noticeable and a crack in the planks now and then is only natural. Then adapt the movements to the natural cracking sound.

+
+## Body Training
+
+_Taijutsu_ literally means _body art_. The aim of this training, which is the most important basis in Ninjutsu, is to develop a natural fighting style that is completely adapted to the fighting person. A timeless understanding of human behavior and physique is of paramount importance. In Ninjutsu, the goal was never to win belts, collect trophies, or acquire titles. This effective way of fighting was designed to survive, to end a fight quickly and effectively, and without self-imposed rules.

+{% duoColorImage
+ "/assets/images/book/scheme-taijutsu-en-light.svg",
+ "/assets/images/book/scheme-taijutsu-en-dark.svg",
+ "Scheme of Taijutsu"
+%}
+
+_Taijutsu_ also includes techniques that allow weaker people to successfully assert themselves against stronger, faster, or larger opponents.
+
+## No Sport or Competition
+
+In the minds of most people, there is still a sense of fairness and competitive ethics. For this reason, the combat system of _taijutsu_ is looked down upon by many. Above all, Zen-like martial arts systems such as Karate or Jūdō, which have become widespread today, adhere to _competition rules_ and fairness. It should only be noted that these systems lose their ability to serve as self-defense. There is no second place in street fighting. The second could be carried away in a metal coffin. Ninjutsu aims for victory, using any means that can be used to achieve it.
+
+That’s why the focus of the training isn’t on dull learning of techniques, but rather on becoming aware of the feelings that arise during a fight. The combat system of Ninjutsu is not limited to a fixed number of techniques but consists of countless variations. Unarmed combat is mixed with stick techniques, sword blows, and other weapons. Thus the student slowly gains a sense of an all-encompassing combat system. Many other combat systems force their students to react according to fixed technical sequences. The _taijutsu_ works in exactly the opposite way. The student learns to let go of all the superfluous techniques and body movements that he has acquired unnoticed over the years.
+
+## Natural Body Movements
+
+The student is not forced to imitate animals or to distort or deform the natural body position. He learns how small changes in position or lowering the center of gravity enable a secure, superior stance. The effective combat system of Ninjutsu is based on the Ninja’s faith in harmony with nature. The basic fighting positions and techniques have also been developed according to the elements of our environment. The five elemental manifestations symbolize solid, liquid, energetic, gaseous, and sub-atomic forces. These are _chi_ (earth), _sui_ (water), _ka_ (fire), _fu_ (wind), and _kū_ (emptiness).
+
+- Earth symbolizes stability, one withstands any onslaught, one is insurmountable. The movements come from the hips.
+- Water symbolizes evasive movements and sudden unexpected movements. The movements come from the abdomen.
+- Fire represents determination, quick, dynamic movements that come from the solar plexus.
+- Wind represents defensive, non-tangible combat. The movements come from the heart area.
+- The Void itself is not included in the combat system, because Void represents thoughts, words, and actions that prevent combat.

+
+## The School of the High Tree Willow Spirit
+
+In 1569, during the Yeiroku era (1568-1579), in the Funagata Yama area of Miyagi, there lived a mountain priest from the Abe family who was named Unryu (cloud dragon). The _bugei_ _ryūha_ Daijiten transmits his name as Sounryu. He was an expert in _shuriken_, _bōjutsu_, _yari_, _naginata_, and _taijutsu_ of the Amatsu Tatara Rinpo Hiden Makimono.
+
+The Amatsu Tatara Scrolls were kept by the Abe, Nakatomi, Otomo, and the Monobe. Takamatsu Sensei’s family also had a copy because they were related to the Kuki family.
+
+Unryu taught his system to Ito Sukesada, a famous martial artist of his time. He was a Samurai from Katakura Kojuro in Fukushima Province and added _hanbō_, _kenjutsu_, and _kodachi_ to the teachings of Unryu.
+
+He taught the techniques that would later become Takagi-yoshin-Ryū, Takagi Oriemon Shigenobu, a young Samurai from Tohoku-Shiroishi Han in Oku. He was born on April 2, 1625, and died on October 7, 1711. He attained the _menkyōkaiden_ when he was just 20 years old. On August 15, 1695, he was appointed _shihan_ in 6 different martial arts of the imperial bodyguards by Emperor Higashiyama.
+
+He modified, improved, and expanded the techniques he had learned from Ito and summarized them as Takagi-yoshin-Ryū, named after himself.
+
+He studied eagerly to improve himself, to avenge his father’s murder. His father had left him a valuable lesson:
A willow is flexible, but a tall tree is fragile
.
+
+The style has been called variously throughout history, including _jū tai jutsu_, jūjutsu, and _daken taijutsu_. The Ryū was heavily influenced by the Takenouchi Ryū jūjutsu and the Kukishin-Ryū.
+
+In the 17th century, the _sōke_ of Takagi-yoshin-Ryū, Takagi Gebboshin Hideshige, and the _sōke_ of Kukishin-Ryū Ohkuni Kihei Shigenobu had a competition and became close friends. Both systems exchanged information and were therefore restructured.
+
+The Ryū was passed on to Takamatsu Toshitsugu by Mizuta Tadafusa Yoshitaro in August 1908, and to Hatsumi Masaaki in May 1959.

+ - biography
+---
+
+## Birth
+
+Takamatsu Toshitsugu was born in the 22nd year of the Meiji Period, on March 10, 1889, in Akashi, Hyogo Province, Japan. His name was Hisatsugo, but he later changed it to Toshitsugu. As a child, he was called Jutaro.
+
+Throughout his life, Takamatsu went by many names: Nakamushi (crybaby), Kikaku (demon horns), Kotora (little tiger), Moko no Tora (Mongolian tiger), and after his death, Bujin (divine warrior). His disciple Hatsumi Masaaki named the 9 traditions Bujinkan in his honor.
+
+Takamatsu suffered from low blood pressure throughout his life, so he drank a glass of saltwater every day. He liked to paint in the morning, going to bed at 9 pm every day and getting up at 6:30 am, then rubbing himself down with a wet, ice-cold towel.
+
+He ate three meals consisting of bean paste, sesame, vegetables, and buckwheat flour. He also ate a lot of small fish.
+
+Takamatsu is said to have never done any warm-up exercises before training, even when fighting with real weapons.
In a real fight you don’t have time to warm up either
he always said.
+
+When he first saw judo on TV, he was said to have been indignant because they arched their backs during a technique in the sport.
+
+## Childhood
+
+He was separated from his birth mother, Fushi, before he was even a year old, and had nine different foster mothers by the time he was twenty.
+
+His father was Takamatsu Yasaburo, also known as Takamatsu Gishin. He often changed jobs, he was a salesman for Sanyo Railroad, later he owned a match factory in Kobe.
+
+Takamatsu attended Akashi no Miya’s English School and later a Chinese formal school. He was a frail and self-pitying child, which is why he was nicknamed _Crybaby_.
+
+## Cruel Training with Master Toda
+
+His father wanted him to be a strong warrior. Therefore, at the age of nine, at his father’s request, he began to study martial arts. He went to the Dōjō of his uncle Toda Shinryuken Masamitsu in Kobe, who also ran a chiropractic practice there. Toda was a Samurai from the Iga region whose ancestors were Ninja, but this only came out after Takamatsu’s death. He had been a sword instructor at a Tokugawa military school.
+
+{% figure "Takamatsu Sensei in old age" %}
+
+
+
+{% endfigure %}
+
+Toda didn’t teach Takamatsu any techniques, but pushed him around the Dōjō with his students and tried throws on him. Takamatsu vowed never to go to the Dōjō again but returned every night.
+
+Every day he came home with bleeding elbows and knees. Takamatsu recalled feeling
like a lamb going to the slaughterhouse
every day. But soon he grew stronger and gained weight.
+
+After a year, Master Toda taught him the first techniques of the Shinden-fudo-Ryū. Toda realized that Takamatsu was very gifted at learning budo. At the age of thirteen, he mastered the Shinden-fudo-Ryū.
+
+While he went to the Akashi no Miya’s English School in Kobe, he attended a Chinese educational school. Every other day he went to the Dōjō of Mizuta Yoshitaru Tadafusa and learned the Takagi-yōshin-Ryū _jū tai jutsu_.
+
+At the same time, he learned from Toda the Togakure-Ryū ninpō, the Koto-Ryū _koppō jutsu_, the Gyokko-Ryū _koshi jutsu_, the Gyokushin-Ryū ninpō, and the Kumogakure-Ryū ninpō.
+
+Takamatsu liked the Koto-Ryū, but he didn’t like the Togakure-Ryū. The Koto-Ryū strengthened the hands and feet, especially the fingers and toes. Through years of intense training, banging his hands against rocks and other hard objects, his fingernails and toenails were 4 to 5 millimeters thick, so he couldn’t cut them with regular nail scissors. He could use it to rip the bark off a tree. He later said that such weapons were no longer necessary today.
+
+On a Sunday evening, Takamatsu was walking through the seaside park when he saw two children fighting with each other. One child was about 8, the other 12 or 13. At that moment 4 men appeared and helped the older child. When one of the men hit the child, Takamatsu intervened and moved against the men. He managed to evict all four.
+
+He later learned that the men were professional Sumō fighters, and one was a fighter whom no one had yet defeated.
+
+## Takamatsu as Local Hero
+
+At the age of thirteen, in a street brawl provoked by about 60 _furyō_ (delinquent young people), he defeated ten of the 60 attackers and routed the rest. The attackers, some of whom were armed with swords, tried to force him and a friend to bow to the leader. Takamatsu knelt down, grabbed a rock, and smashed it on the leader’s foot. He fell to the ground and cried out loud. The others attacked Takamatsu. He managed to take out 5 to 8 attackers as the rest fled. The next day, a policeman came to his house and took him to the police station. He wanted to know how many others were there. The policeman did not want to believe that he had defeated the attackers alone, but the friend confirmed this and stated that he had not fought himself.
+
+The next day the newspaper read:
13-year-old judō expert easily puts 60 gangsters to flight
.
+
+## The Sumō Match
+
+At that time, Takamatsu was also a spectator at a Sumō wrestling match. A great fighter named Oni no Yama (Demon Mountain), who had defeated many fighters before, fought Raiden (Lightning). Oni no Yama simply knocked Raiden to the ground and threw him out of the ring. Takamatsu jumped up and entered the ring in his normal attire. When asked his name, he said his name was Akebono. Takamatsu defeated Oni no Yama and eight other men. Then a man who called himself Osakayama climbed into the ring. He was huge and weighed 112 kilograms. Takamatsu weighed only 59 kilograms. The two fought hard, but no matter how hard Takamatsu tried, he couldn’t move the heavy man. Osakayama grabbed his wrist and squeezed it hard. Takamatsu managed to throw Osakayama off balance, causing him to step out of the ring. The crowd cheered and tossed their seat cushions in the air.
+
+The next day, Osakayama came to Takamatsu’s father and told him he was a professional Sumō wrestler from Osaka. He wanted to train his son to be a Sumō wrestler. But Takamatsu’s father refused because his son should become a soldier. It was only through the visit that he learned that his thirteen-year-old son had defeated a professional Sumō wrestler.
+
+## Fight Against Karate Students
+
+At the age of fifteen, his master asked him to compete against two Musashi-Ryū karateka, aged 27 and 28. The first underrated Takamatsu and was defeated by a _gyakunage_.
+
+The other fighter was warned and when Takamatsu tried to throw him, he hit his right ear and right arm as he fell, knocking Takamatsu out.
+
+When the fighter learned that his opponent was only 15 years old, he was very impressed and said that he could not win against him again because Takamatsu now knew the secret technique of Musashi-Ryū (_mushadori_).
+
+As a result of the battle, Takamatsu suffered hearing damage in his right ear throughout his life, which is why he was later not admitted to military school.
+
+At the age of seventeen, he received the _menkyōkaiden_ of Takagi-Ryū from his teacher Mizuta Yoshitaru Tadafusa. It was not uncommon at that time to give a student the _menkyōkaiden_ early on to encourage them to try harder.
+
+## Training With Ishitani
+
+That same year, Takamatsu met Ishitani Takakage Matsutaro, who worked as a bodyguard at his father’s match factory. Known throughout Japan as a famous fighter, Ishitani set up a small Dōjō at the factory and taught Takamatsu Kukishinden-Ryū _happōhikenjutsu_, Gikan-Ryū _koppō jutsu_, and several other aspects of Ninjutsu.
+
+When Takamatsu was eighteen, he fetched 330 gallons (1 gallon = 4,546 liters) of freshwater for his father’s factory from a well every morning. The source was at the foot of Maruyama Mountain and 7 to 8 blocks from the factory. He had to fight five times, and each time he had to carry 240 kg of water home. This greatly strengthened his body.
+
+## The Night Attacker at the Bridge
+
+One day a man from the factory told him someone had stopped him at Shinbashi Bridge last night. Whenever he evaded, the man blocked his path again. Finally, he grabbed it and threw it in the water.
+
+During the following night, Takamatsu crossed the bridge several times without anything happening. He thought that the attacker might know him and disguised himself the next night. And as expected, a person blocked his way the next night. She wore a hat that hid her face. The attacker tried to throw Takamatsu, but couldn’t. He then tried to punch and kick him, but Takamatsu dodged the punches and kicks. When the man became confused, Takamatsu threw him to the ground and the attacker ran away. He lost his hat while escaping, and Takamatsu realized it was a student of Master Mizuta. He shouted after him to be ashamed of shaming his school in this way.
+
+Takamatsu received from his grandfather Toda the _menkyōkaiden_ of the Shinden-fudo-Ryū, Togakure-Ryū, Kumogakure-Ryū, Gyokushin-Ryū, Koto-Ryū, and Gyokko-Ryū. Soon after, in 1909, Toda Shinryuken Masamitsu died. Takamatsu was named the next _sōke_.
+
+Before he died, he is said to have said to Takamatsu:
Even if you face certain death, die laughing
.
+
+In 1910, Ishitani Takakage Matsutaro also died and Takamatsu was appointed _sōke_ of the Gikan-Ryū and Kukishin-Ryū.
+
+## Trip to China
+
+Soon after, he quit his job at the match factory and traveled to China partly because he wanted to test his skills, because he was dissatisfied with his life and because he wanted to make money. The situation in China was turbulent at the time, with many warlords fighting for the country.
+
+On his way to China, he met Kim Kei-mei in Korea, who taught him eighteen Korean and Chinese martial arts.
+
+## Illness and Return
+
+Then he got sick and went back to Japan. He wanted to visit his friend Kogane’s grave and pay a visit to his grandmother. She was happy when she saw him and offered him to cure his illness with her. He was suffering from beriberi (vitamin B1 deficiency, which occurs when husked rice is eaten).
+
+But a month later, a messenger came to say that Takamatsu’s father would stop making monthly payments to the grandmother if she continued to shelter his son. Takamatsu was very ill, the disease had severely damaged his lungs. Despite this, he could not allow his grandmother to be harmed, and two days later he left the house with only his clothes on.
+
+## The Hut in the Mountains
+
+His legs were heavy and swollen from the disease as he trudged towards Mt. Mayasan. Without his Ninjutsu training, he wouldn’t have been able to walk anymore. He crawled up the mountain on his hands and knees until he came to a waterfall. There was a small hut that was about 4 meters wide and long. The cottage was very airy.
+
+At the foot of the mountain, he had bought 2 liters of rice. He had forgotten matches and therefore could not make a fire. But he recalled that his master had once told him that it was important for a Ninja to eat natural food. So he washed the rice and put it on a stone. The sun made the rice floury as Takamatsu mashed it with his hands. He only had a photo of Master Toda with him, to whom he was speaking. When he thought that all his masters, Toda, Ishitani, and Mizutani had already died, the raw rice tasted like the best thing in the world to him.
+
+He was already feeling a little better and rested for a few days. Only the birds and the wind kept him company.
+
+One evening somebody shouted:
Go home!
. But Takamatsu couldn’t see anyone and fell asleep again.
+
+## Healed by a Yamabushi
+
+After a few days, an old man came to the waterfall and asked why he was practicing asceticism. Takamatsu replied that he wanted to recover from his illness. The old man said it wasn’t that difficult, he had beriberi and tapeworms in his stomach. He said he could heal Takamatsu. First, he would fight the tapeworms. He clasped his hands and murmured a few sounds. Takamatsu was a little puzzled, wondering how that would help. He then stabbed Takamatsu in the stomach and said he would come back in a few days.
+
+A few days later, Takamatsu felt a sharp pain in his abdomen and relieved himself. He found two tapeworms in the excrement. After ten days the old man returned. He said this time he will cure the beriberi. After the procedure, he disappeared without making a sound.
+
+After seven days, Takamatsu managed to get up. He started practicing taijutsu again and regained his strength. He changed his name from Jutaro to Kikaku to remind himself that he could always do whatever he set out to do.
+
+The _yamabushi_ returned once more to inquire how Takamatsu was doing.
+
+## Second Trip to China
+
+After that, Takamatsu went back to China. He stayed in North China and Manchuria for ten years.
+
+{% banner "Conflicting Reports" %}
+
+It’s not quite clear here and there are conflicting reports as to whether Takamatsu took money or paid the bandit compensation.
+
+{% endbanner %}
+
+Once in the mountains of China, he was attacked by some bandits. One of the perpetrators grabbed his waist. Suddenly he started screaming and clutched his face. Takamatsu didn’t know what he had done to the man, but then he felt something soft and warm in his hand and he realized it was the bandit’s eye. He gave the bandit first aid, and then took money for help.
+
+## Martial Arts Teacher in China
+
+{% figure "Takamatsu in China. Pictured here on the left." %}
+
+
+
+{% endfigure %}
+
+By the time Takamatsu was 26 years old, he had already won 19 bouts, of which only 7 were competitions, in various places in China. Lord Ren, the uncle of the Emperor of China, regarded Takamatsu as his own son. Takamatsu was a famous teacher, having trained more than eight hundred Chinese, Japanese, American, and French students. Every day he trained 70 to 80 students. Even in the heat of the summer, he didn’t sweat a drop. A Shaolin kung fu master, Choshiryu from Santo Province twice challenged Takamatsu to a competition, but he refused each time.
+
+## Takamatsu’s Dream
+
+One night he had a dream. A huge red demon tried to slay a butterfly with an iron bar. But the butterfly kept flying away until the demon collapsed in sweat and cried _enough_.
+
+The next morning he created a new technique. When Choshiryu challenged him again, he accepted. The challenger was 37 years old and weighed 112 kilograms, Takamatsu weighed only 74 kilograms. The tournament took place in an English settlement. Takamatsu dodged Choshiryu’s punches and kicks for 2 hours. As he slowed down and sweat dripped from his forehead, Takamatsu saw his time and wanted to attack.
+
+But Lord Ren stopped the fight because everyone saw that Choshiryu had no chance anymore. After the tournament, they congratulated each other and toasted their new friendship.
+
+When Takamatsu came back to Japan, he became the head of the Nippon Minkoku Seinen Botoku Kai (Japanese Martial Arts Organization).
+
+## Monk of Tendai
+
+He went to Mount Hiei near Kyōto to become a monk at Tendai Monastery. Perhaps in this way, he tried to redeem the sins of his youth.
+
+He became a respected monk and representative of the monastery and also became deeply involved in Shintō and _mikkyō_.
+
+The Kuki family had transferred the _menkyōkaiden_ of the Kukishin-Ryū to Iwami Nangaku in his absence, believing he would not be coming back to Japan.
+
+During World War II, the scrolls of the Kuki family were destroyed by fire during an Allied bombing raid. Takamatsu reconstructed the scrolls through his notes and his memories and presented them to the Kuki family 3 years later. For this, he received permission to create a sub-school, the Kukishinden-Ryū.
+
+## Marriage and Establishment of a Dōjō
+
+He married 23-year-old Uno Tane and adopted a girl, Yoshiko because they had no children of their own.
+
+He founded a small Dōjō, the Sukisha Dōjō (place for people who love martial arts) and trained with a small group of students. Some of them were Koba Koshiro, Sato Kimbei, Hanaoka Nangaku, Ueno Takashi, Takeuchi Kikakusai, Kimura Masaharu, Fukumoto and Akimoto Fumio.
+
+He ran a small tea house and hotel in Kashiwabara in the Nara region.
+
+## Hatsumi
+
+{% figure "Takamatsu Sensei with his student Hatsumi." %}
+
+
+
+{% endfigure %}
+
+In 1958 he accepted a new student named Hatsumi Yoshiaki, who was 26 years old. For the next fifteen years, he taught only Hatsumi, who traveled to his teacher in Japan every weekend. Takamatsu taught Hatsumi things he had never taught a student before. A few years before his death, he said to Hatsumi:
I taught you everything I know, thus repaying their kindness to Toda Sensei, Ishitani Sensei, and Mizuta Sensei.
He decided to leave his inheritance in the hands of Hatsumi because he is the most suitable.
+
+## The Challenge
+
+In the late ’60s Takamatsu wrote an article in which he said:
When fighting, one must prepare to be killed by or kill an attacker
.
+
+As a result, a Japanese karate teacher gave an interview on television and said that what Takamatsu said was outdated today and called him an
old man whose time is up
.
+
+Takamatsu saw this as a challenge and in turn, said on TV that he was still far from the end and would accept the challenge. He would give the man three days to publicly apologize or fight and kill him. The karate teacher apologized publicly.
+
+Takamatsu trained in martial arts until he was 80, after which he only observed Hatsumi’s training.
+
+## Death
+
+On April 2, 1972, he died at his home in Nara (east of Osaka) and was buried in the Kumedra Cemetery near Nara.
+
+Hatsumi, in memory of his teacher, decided to name his Dōjō **Bujinkan** Dōjō, which means **
The Hall of the Divine Warrior
**.
+
+Only after his death did the neighbors find out about his eventful life and were very
impressed
. Few knew he was a Ninja.

+## Ten or Heavenly Principles
+
+These principles create an altered world around the Ninja by changing the environment. The balance between _in_ and _yō_ is shifted in such a way that the Ninja can remain the same, but his environment must change.
+
+Increasing the influence of _yō_ on the environment means increasing the enemy’s vulnerability. So you can for example make the opponent eager to fight, even when it would be better if they rested. The Ninja can also keep the opponent moving when they should be resting. Or you can get your opponent to give up a good position.
+
+As _in_’s environmental impact increases, if your opponent is itching to fight, you’ll make them wait, because nothing is more frustrating than holding back surging energies and waiting. Or they are left in the dark about the correctness of the information, lured into narrow corridors or rooms where they cannot fully develop their supremacy.
+
+### Gojō goyoku
+
+In order to influence other people, the Ninja used the tactic of _gojō goyoku_. The opponent is weakened and manipulated by his own weaknesses and mistakes.
+
+- With the principle of **kisha**, the opponent is brought down by his own vanity. He is flattered and praised.
+- With the principle of **do sha**, his irascibility and uncontrollability are exploited. He is made to do ill-considered, stupid actions.
+- If the principle of **aisha** is applied, the generosity and sentimentality of the opponent are exploited. You make him feel sorry or regretful.
+- **rakusha** takes advantage of the opponent’s laziness and inertia. You offer him money or luxuries, women or comfort, and bring him down.
+- The **kyōsha** principle uses the cowardice and fear of an opponent. He is threatened, intimidated, blackmailed, and thus kept under control.
+
+But these tactics only work for a limited time, eventually, every tactic wears out. Therefore, in the long-term context, one must carefully consider whether the use of _gojō goyoku_ is beneficial.
+
+Another way of influencing other people is to satisfy their wants and needs. There are five great needs that every human being is subject to. Of course, there are more, but most fit into one of five categories:
+
+#### Safety
+
+By providing shelter and sustenance to those being pursued, the Ninja makes them dependent and gains control over them. Ideals and political beliefs dwindle when the foundations of survival are not secured.
+
+#### Sex
+
+Almost every person is dependent on the fulfillment of their sexual desires. Men in particular are very easily susceptible and therefore easy to control. When love comes along, caution and common sense fall by the wayside.
+
+#### Prosperity
+
+
Every man has his price
. Everyone is on the hunt for a certain amount of wealth, which in turn usually also meets their other needs. With the right amount of bribery, anyone can be manipulated and controlled, earning their temporary loyalty.
+
+#### Pride
+
+Everyone needs the feeling of recognition for achievements and pride resulting from this. When a Ninja appears to elevate and shower another with pride, that Ninja becomes dependent and vulnerable to manipulation and control.
+
+#### Pleasure
+
+Most people need pleasure, joy, and distraction. It is not for nothing that television, games, and events are always in high demand. When a Ninja provides pleasure for a person, that person becomes dependent on him and is easily controlled.
+
+## Chi or Earth Principles
+
+These principles create an altered environment where the Ninja changes but the environment stays the same.
+
+If he increases the influence of _yō_ on himself, he creates more favorable conditions for himself. If the opponent is stronger or better, he practices and improves until he can trump him. If the opponent has more information, he collects more information in turn. If the opponent’s troops are in the majority, he, in turn, strengthens his ranks.
+
+Increasing the influence of _in_ on the Ninja decreases the threat. If the Ninja is being pursued, he will fall back behind the enemy. If he falls into a raging torrent, he doesn’t fight the tide but simply lets himself be carried downstream. If he is exposed as an agent, he offers his services to the enemy. The Ninja avoids hasty judgment of a situation and tries to evaluate neutrally. If for example, a murderer is lurking in a dark house, you imagine him waiting in the dark, gun drawn, knowing exactly where you are. If you change your point of view, the murderer suddenly seems small and abandoned. He’s waiting in a dark house, not knowing if we’re even going to enter it, which way we’re going, or what weaponry we’re carrying. He feels lost in the dark.
+
+Or in another example, we are faced with a large, physically superior opponent. We could imagine one punch from him destroying us. But when we change our position, the opponent suddenly seems immobile, hampered by his body mass and muscles. Our speed can hit him in vulnerable spots he can barely protect.
+
+## Jin or Human Principles
+
+These principles create what appears to be an altered environment around the Ninja without the environment or the Ninja changing. Illusions and tricks only pretend that the situation has changed. The principles of _in_ and _yō_ are exaggerated, so that as an outsider one can no longer see through the true situation.
+
+This tactic is called **kyojutsu tenkan ho**, which means lie and truth. The Ninja presents the truth as a lie and the lie as truth. Thus the Ninja can show strength when in fact he is weak, or he can hide his strength when he is strong. We can exaggerate to such an extent that the opponent senses the deception and thinks we’re trying to deceive them, when in fact that’s not the case.
+
+In the Middle Ages, for example, a Ninja could scream wildly at the guard at the gate and tell them about an attack on the other side of the castle or about a fire. The guards moved in that direction and the Ninja was able to exit the castle unhindered.
+
+Or he threw a heavy stone from the wall into the water. The guards now focused on searching the shore and the Ninja was able to escape elsewhere.
+
+A very effective technique for close combat is mentioned here. If the opponent wants to grab the Ninja in close combat, you don’t resist it, but even pull him to your body. He will responsively move his power into the opposite side and pull back with all his might. This is when you reverse your power and throw your opponent.
+
+If you are being pursued by an attacker, you can suddenly slow down, hook the enemy and flee in a different direction. Or you jump at the opponent and pinch your legs behind your back, then drop to the ground and pull the opponent with you.
+
+A Ninja wasn’t afraid to do _dirty_ tricks either. In a fight to the death, it doesn’t matter how honorably you died. Pulling the hair, flattening the nose, tearing the ears, kicking in the soft parts, sand in the eyes, etc. are only a small part of the repertoire.
+
+An important aspect of Ninjutsu is **in shin tonkei**, maximum effect with minimum effort. The Ninja always tried to change the natural course of things as little as possible.

+
+> Whenever one is sad, unhappy, sick, wounded, or in despair, one should remember these five commandments.
+>
+> 1. Forget your sadness, anger, envy, and hatred. Let them pass like smoke in one breath. Don’t give in to such feelings.
+> 2. Do not deviate from the path of righteousness. You should live a life worthy of a human being. It is this simple philosophy that has been repeated by sages for many ages. […]
+> 3. Don’t hold on to greed, luxury, or your ego. If you learn the martial arts just for your own benefit and always try to be dependent on others just because it’s easier, you will be controlled by these three desires – even if you have reached a high rank in the martial arts. These three desires distort not only martial arts but also humanity. When people die, there are two paths to death: joy and sorrow. Joy is meant here in the heavenly sense, and not pleasure or the past. When one reaches this stage in life, one realizes one’s true purpose in life.
+> 4. You should accept suffering, sorrow, or hate as it is and see it as a chance from the Almighty for a test. It is the noblest spirit in Ninpō to regard everything as a blessing of nature. When you’re trying to get things done, sometimes your goodwill is portrayed as bad by some people who are obsessed with their own selfishness. […]
+> 5. Be fully engaged in budō with both your time and mind and be deeply focused on Bujutsu with your mind. Read between the lines of the late Takamatsu’s story […] and you will learn the attitudes and methods to be followed in Ninjutsu training. […]

+title: "The Rules of the Ninja"
+priority: 805
+date: 2006-04-02T15:20:00+02:00
+author: "Stefan Imhoff"
+excerpt: "10 rules established by Hatsumi Masaaki that are timeless and should apply to all Ninja."
+translationKey: "rulesOfNinjaPage"
+categories:
+ - guidelines
+---
+
+> Whenever I’ve tried to find a reason for the survival of the nine traditions of Ninjutsu over a thousand years of history, I’ve believed it is because each _sōke_ or _head of the family_ shared their experiences in writing and orally. The heads of the family risked their lives to attain enlightenment and their experiences became the rules of the Ninja.
+>
+> The Ninja created these rules to attain divine wings. The rules were created naturally and fit into any time and any situation. Through them, one becomes aware of _kyojitsu tenkan ho_, or the proper use of truth and falsehood in the training of _ninpō taijutsu_. These rules are like the _seven ways, three directions_ of the Ninja method of disguise; the seven mysteries of disguise and the three directions add up to ten. Ten symbolizes a good force that conquers evil.
+>
+> The Ninja’s goals are: **First** to use Ninjutsu to infiltrate the enemy camp and monitor the situation. Then strategies for a surprise attack or inner turmoil can be developed. It is true that we have no choice but to strive for victory when the enemy stands against us, but normally we should obliterate ourselves in order to bring our actions to a successful conclusion. Here I am speaking of enemy land as something that has form, but I would like to mention that enemies can also be found in nature and in the souls of other people. These efforts should be used for the rulers and the country to protect their own country and themselves, and ensure peace for both sides.
+>
+> **Secondly**, a Ninja should help the rulers and the country with a righteous spirit, and cultivate his soul for teachers and parents. He must not use Ninjutsu for his personal gain, desires, or for the purpose of entertainment.
+>
+> An important point in the struggle to protect justice is that the enemy’s justice is often misinterpreted as not being justice.
+>
+> We are to offer our services to our teachers and parents. In Japan, there is a rule that says the bond between parent and child lasts one generation, between man and woman two generations, and between teacher and student three generations. This shows how much we owe our teachers and how important it is to offer our services to them.
+>
+> I would like to speak about myself, fifteen years after the death of Master Takamatsu. My students have evolved and I feel I can now truly call them students. […]
+>
+> It is not allowed to use Ninjutsu for the purpose of entertainment or to perform magic. When one uses Ninjutsu for such purposes, it is no longer Ninjutsu but sorcery or sorcery. Such a person will not be able to live in a society where he opens up to others but will live together with the snakes, toads, and snails in a world where the sun never shines.
+>
+> Awareness stemming from self-interest or egoistic desire sends you in a direction without a goal. If you forget the Ninja rules and hop on this _tram_ with violent thoughts you will arrive at the terminus _criminal_ or _prison_ or _steel coffin_.
+>
+> There’s something oddly fascinating about Ninjutsu. A bad Ninja who takes advantage of what he has learned will appear as a vulgar merchant or stupid criminal. Just as followers grow sluggish after the training hall is firmly established, a Ninja’s skills grow feeble when he visibly attends to his needs.
+>
+> **Third**, Ninjutsu places great importance on _hojutsu_, which is _kyojitsu tenkan ho_, or the method of switching back and forth between truth and lies. You can use _taijutsu_ without revealing yourself to the enemy, but if you have no other choice, you can use _happōhiken_ or the eight sword-wielding methods or use Ninja tools to confuse the enemy.
+>
+> It’s important to confuse him. One might say _hojutsu_ places more emphasis on attacking the mind than the body. This means the Ninja uses techniques of investigation, espionage, stealth, and uses both truths and lies side by side to achieve his goal. […]
+>
+> **Fourth**, Ninja must master the use of explosives, Ninja tools, and drugs – both good medicine and poisonous drugs. It’s important to follow the rules about not killing an enemy. The Ninja realized the principle that a bad ending destroys them. And considering human life, a person is dead when his spirit is dead, even if the body is alive. The Ninja promoted this spirit of justice.
+>
+> **Fifth**, a Ninja should spend considerable time practicing his weapons. It is written to take advantage of it and learn from his instincts. Gun use changes over time, and what is valid today may not be valid tomorrow. You should practice being able to use any weapon. When I visited New York, everyone was amazed that I could use any weapon that was given to me. They called me a magician.
+>
+> **Sixth**, a Ninja should always come into direct contact with meteorology, physiography, and geography. Through meteorology and physiography, we can understand the changes and true appearance of nature. This is not academic learning, but rather an experience that involves the whole body so that we can understand the silent language of nature through the transmission of feelings and sensations. This could be viewed as _talking with God_.
+>
+> **Seventh**, at a time when Japan was in civil war, Ninja who broke the law were severely punished. Even the closest relatives were beheaded, exiled, or banished. As the war escalated, Ninja repeatedly found themselves in the tragic situation of having to live within the confines of those rules. This is also why they developed a philosophy that says you should always try to avoid a fight and steal away or flee until the fight is over. […]
+>
+> **Eight** Ninja are not allowed to kill anyone, injure honorable people, steal money or steal valuables.
+>
+> **Ninth**, a Ninja must always take care of himself, develop a strong body, develop quick movements, and learn and master as many things as possible. I love music, play electric guitar, perform Japanese dances like painting and writing, and I work hard to develop the soul of Ninjutsu.
+>
+> **Tenth**, Ninja must continue their training. There are eighteen areas of training – mental development, unarmed combat, sword fighting, staff and stick fighting, blade throwing, spear fighting, sword spear, chain and sickle, fire and explosives, disguise and impersonating, stealth and burglary methods, horseback riding, water training, strategy, espionage, Escape and Concealment, Meteorology and Landscape Studies.

+
+## Premonition and Intuition
+
+What is that, the ability to sense something happening before it actually happens? The feeling is called the seventh sense, intuition or anticipation. Many of us often have impressions or feelings, hunches, but most reject these feelings and do not allow them.
+
+A Ninja trains himself in honing this perception so that he becomes able to sense and avoid danger. In the _godan_ test in the Bujinkan, the teacher silently approaches the student with a sword (today a _shinai_). At this stage of the training, the student should have improved his senses to such an extent that he can sense the danger of the sword stroke and avoid it with an evasive movement.
+
+It is a fact and has now been scientifically proven that a person sitting in a coffee shop somewhere often feels a kind of uneasiness when someone starts staring at that person.
+
+## The Seventh Sense in the Sakki Test
+
+Hatsumi himself reports that during the _sakki_ test (test for 5th dan, the student must dodge a sword without seeing it) he felt pressure on his shoulders from his master Takamatsu and saw an image of a hacked body in his mind’s eye. He performed a side dodge and passed the test.
+
+These subtle feelings that the electromagnetic force fields of others have on us are felt more strongly by some than by others. But if you continue to practice persistently, you can go far in this art.

+author: "Stefan Imhoff"
+excerpt: "Togakure-Ryū ninpō – The School of the Hidden Door, a Ninja-ryu founded by Daisuke Togakure, is now almost a thousand years old."
+translationKey: "togakureRyuPage"

+
+## The School of the Hidden Door
+
+In 637 Gyoja E’no founded the _mikkyō_ sect on Mount Hiei zan. His disciple Dengyo Daishi founded the Tendai _shugendō_ sect of Buddhism and established its Enryakuji monastery on Mount Hiei zan. These monks still exist today and still practice _shugendō_ or mountain asceticism: purifying one’s self through trial and suffering.
+
+Near Mount, Hiei zan was a small place called Togakure in Shinano Province. Around 1161, Nishina Daisuke was born here into a Samurai family. He studied early at Tendai Monastery on Mount Togakure (Mount Hiei zan) near his village.
+
+These early experiences played an important role as Daisuke later established a system of combat, survival, and infiltration.
+
+It is important to understand the reasons that led to the establishment of Togakure-Ryū ninpō. Nishina Daisuke’s father was Nishina Yukihiro, who was a high-ranking Samurai in the service of Prince Minamoto Yoshinaka, cousin of the first Shogun of Japan.
+
+When Minamoto Yoshinaka was a young child, a Samurai was sent by one of his rivals to kill him and his mother. Yoshinaka’s mother escaped with him and secretly went to the home of a farmer loyal to her family. Later, Yoshinaka was taken to Kiso Village in Shinano, not far from Togakure Village.
+
+Togakure’s Nishina Yukihiro came into his service. Years later, Yoshinaka’s family had defeated their rivals and became rulers of Japan. But Yoshinaka was seen as a threat to leadership and many turned against him. Minamoto Yoshinaka had changed his name to Kiso Yoshinaka, the name of the place where he lived, which was common in the past. In 1184, Yoshinaka was attacked by his half-brother’s army. Sixty thousand Samurai met Yoshinaka’s army near Kyōtō. The battle was called Awaze no Kassan and Kiso Yoshinaka was killed by an arrow in the eye. On his side had fought Nishina Yukihiro of Togakure, who was also killed, and his son Nishina Daisuke, who survived.
+
+Because he was on the losing side, Daisuke had to flee from persecution to distant Iga. He fled to the far-off places hidden in the mists of high mountains and dense forests. He changed his name to Togakure Daisuke, named after the place of his birth.
+
+When he was in Iga, Daisuke was found by Kain Doshi (Kagakure Doshi). Kain Doshi was a _shinobi_, the third _sōke_ of the Hakuun-Ryū, who was one of the original Ninjutsu systems created from the teachings of the Ikai (Yi Gai, who brought the roots of koshi jutsu from China).
+
+It’s quite possible that Doshi was Daisuke’s uncle and that Daisuke fled to Iga to find him.
+
+Daisuke learned Doshi’s warrior teachings and added them to his own _shugendō_ beliefs, the beginnings of Togakure-Ryū were found. But Daisuke did not study alone under Kain Doshi. With him was Minamoto no Kanesada Shima Kosanta. He was a high-ranking Samurai retainer who had also fought in the Battle of Awaza no Kassan and had become friends with both Daisuke and his father. Shima had been wounded in the battle and was taken to Iga by Daisuke. He was to become the second _sōke_ of the Togakure-Ryū. After Daisuke’s death, he took the name Togakure Daisuke II. His son Togakure Goro, the third Soke, changed the teachings of Togakure into the Ninjutsu system that is still taught today. The 11th, 12th, and 13th _sōke_ of the Ryū were named after the capital of Iga Ueno.
+
+It is said that the members of the Hattori clan practiced the Togakure-Ryū. Hattori Hanzo is the most famous of all Ninja. The members of the Momochi family also practiced this system, and the 21st _sōke_ of the Togakure-Ryū was Momochi Kobei, a descendant of Momochi Sandayu, the second famous Ninja and a leading figure of the Iga region.
+
+As in most martial arts, control remained within the family that invented the style and was passed down from father to son. The Togakure-Ryū followed this custom until the 16th century. When the immediate kin died out, it was Toda Nobutsuna, the system’s foremost member, who was put in charge of the Ryū and became the 24th _sōke_.
+
+When the Toda took control around 1625, they added their Ninjutsu system, the Kumogakure-Ryū. They also controlled the Gyokko-Ryū and Koto-Ryū, and from then on these systems were inherited together.
+
+The 32nd _sōke_ of the Togakure-Ryū, Toda Shinryuken Masamitsu, was a swordsmanship instructor of the Tokugawa _bakufu_ in the mid-19th century.
+
+He resigned from this post when he realized that the men he taught swordplay would later kill other Japanese. This was against the law of Togakure-Ryū. The 33rd _sōke_, Takamatsu Toshitsugu, was the last member of the Toda family to control the Togakure-Ryū. Almost a millennium has passed since the founding of the Tendai _shugendō_ sect.
+
+## Sanpo Hiden
+
+### The Three Secret Treasures of Togakure-Ryū
+
+- **Senbanshuriken** – The throwing star had four points. It was also used as a tool. Carpenters used it to remove the nails.
+- **Shukō** – These claws were used for both climbing and fighting.
+- **Shindake** – A bamboo cane, a little over a meter long, used for underwater breathing or as a blowpipe.
+
+## Code of the Ninja of Togakure
+
+Alex Lokanov, a _dan_ wearer from Russia, researched the following saying:
+
+> The stars are my eyes,\
+> The wind is my ears,\
+> The night is my clothing,\
+> The cold is my mind,\
+> The shadow is my essence.\
+> My strength is my persistent striving,\
+> Deferential courtesy with teachers is my inner warmth.\
+> My violence is myself,\
+> The iron is my body,\
+> My decisions are my law!\
+> My mind is my only friend,\
+> Disgust is my enemy\
+> The freedom to take and give life is my strategy.\
+> Seizing a moment is my opportunity.\
+> The law of the universe is my only treasure.\
+> Adaptability is my basic law.\
+> The unassailability of the wind is my way of fighting.\
+> The resourcefulness of the mind is my happiness.\
+> Feeling at home is my armor.\
+> Serenity is my fortress.\
+> Understanding the essentials without reflection is my sword.

+excerpt: "Toiri tactics were used by the Ninja in peacetime. They mainly contain espionage and preventive tactics."
+translationKey: "toiriPage"
+categories:
+ - strategy
+ - tactics
+---
+
+## Chikyujutsu
+
+In this tactic, the Ninja presented a relaxed bow biding his time. When a Ninja was caught, he used this technique. If the hostile master offered him to work for him, he took the opportunity. However, he immediately used the first opportunity to flee.
+
+## Fukurogaeshijutsu
+
+After what appeared to be a fight, the Ninja parted ways with his old master and switched sides. He served his new master for a time. However, when the war reached a critical point, the Ninja carried out his mission and went back to his old master.
+
+## Hotarubijutsu
+
+_The glow of a firefly_ in this tactic meant sending a messenger through enemy territory and having the enemy intercept it with a fake message.
+
+## Joeijutsu
+
+This tactic involves sending a Ninja into enemy territory just before hostilities break out. It was then much easier for the Ninja to go into hiding because the preparations for war were going on everywhere. He could be enlisted as a worker or a soldier.
+
+## Katsuraotokujutsu
+
+This tactic is based on an ancient Chinese tale of a man on the moon. _Katsuraotoku_ was the term for a Ninja in enemy territory. He was isolated from his comrades and dependent on the help of local people. These persons are called _chitsu mishi_. These people offered him their home as a base of operations, helped him with small espionage services, and unobtrusively cared for him.
+
+Sometimes a Ninja would help and provide financial support to a family even in peacetime. So they owed him a favor in times of war.
+
+## Kunoichijutsu
+
+When women were used as agents, they were called _kunoichi_. They were also skilled in combat, like their male comrades, but the bulk of their training also lay in courtly manners, cultivated speech, and psychological influencing. Through them you could get closer to key male figures in order to transport them to the afterlife with poison at the right moment.
+
+## Minomushijutsu
+
+This tactic means _worm in body_. Enemy servants were instigated to betray their master. A high-ranking person was far more important than low-ranking people. Perhaps the Ninja managed to persuade an ally to switch sides with his troops during battle.
+
+## Satobitojutsu
+
+With this tactic, the Ninja looked for a dissatisfied subject of the enemy ruler, a money-greedy or success-seeking person, whom he took into his service. They could serve as informers, keep escape routes clear, or provide them with material and equipment.
+
+## Tanirijutsu
+
+This tactic was the same as _yamabikojutsu_, except that a whole team of Ninja switched sides.
+
+## Tensuijutsu
+
+This tactic (_haunting the sky_) continued to feed information to an enemy Ninja once spotted. However, this was only harmless information or false reports.
+
+Later, you could let the Ninja fall out of favor with his master by obviously wrong information and maybe even recruit him.
+
+## Yamabikojutsu
+
+In this tactic (_the echo of the call_), a Ninja would switch sides and serve his new master for years without ever doubting his loyalty. In response to a predetermined sign, e.g. a light signal or a firework rocket, he changed sides again and before that caused a huge amount of damage or carried out another mission.

+## Strengthen the Body Against Attacks
+
+The _daken taijutsu_ of Ninjutsu involves two different methods that are said to have been developed in China. _Koppō jutsu_ involves bone-crushing techniques against the opponent’s harder bones and _koshi jutsu_ involves stabbing against muscles and organs. In order to make the body weapons more resistant to blows, there are numerous ways to harden them. This is absolutely necessary, as an untrained body weapon easily gets painful swelling or bruising.
+
+## Fingers and Hands
+
+The fingers or hands are strengthened by doing the same thing as a cat. The Ninja slams his hands or fingers against a tree, gradually strengthening them. A cushion filled with lead shots or stones is also suitable. Or you hit the pillow and grab it powerfully.
+
+The best way to harden the spear hand is to poke it in a bucket filled with sand, lead shot, or pebbles. You start with soft sand and as you progress harder sand, small stones and larger stones follow.
+
+## Arms and Shins
+
+The best way to strengthen arms and shins is to bang them against a tree. Training makes you immune to enemy strikes on those _sensitive_ spots. The muscles of the abdomen, solar plexus, neck, and other sensitive areas should be better protected through muscle training.
+
+## Hardening is Uncomfortable
+
+Hardening should be uncomfortable but not painful and allow enough relaxation between workouts. Only a slow increase in hardening leads to success.
+
+The other body weapons are also strengthened on trees or pillows. With enough stamina, the body weapons become effective tools. Grandmaster Takamatsu was able to rip entire pieces of bark from a tree with his fingers. Through years of training, his fingernails became as sharp and hard as daggers.

+priority: 320
+date: 2006-03-28T17:30:01+02:00
+author: "Stefan Imhoff"
+excerpt: "In order to emerge from a fight successfully, several factors are of great importance: endurance, speed, strength and agility. The Ninja trained into these to increase his advantage."
+translationKey: "trainingFactorsPage"
+categories:
+ - training
+---
+
+## Endurance
+
+Endurance is resistance to fatigue from prolonged or repetitive external and internal high loads and a rapid recovery capacity. A skilled fighter must maintain his performance throughout the fight.
+
+To improve long-term endurance, it is recommended to spend 90 minutes a week on a forest run, e.g. run about 30 minutes every other day.
+
+### Why Should You Run?
+
+> **It’s fast** – There are 1440 minutes in a day. If you run 90 minutes a week, that’s 90 minutes out of 10,080. If you’re in your 30s and don’t feel like spending a little time running, prepare to spend even more time being sick.
+>
+> **It’s safe** – Running builds stamina gradually, it’s almost impossible to overexert yourself. And you start at the level you choose for your fitness.
+>
+> **It develops heart and lungs** – Heart, lungs, and circulatory system are improved, you can take in more oxygen. Running also works the parts of the body that muscle training can’t reach (organs). One day your life may depend on your fitness.
+>
+> **You’ll feel better and look better** – Exercising improves your skin and muscles, you look more optimistic. The fat around the hips and legs is shed, tightening the muscles and flattening the stomach.
+>
+> **It helps lose excess weight** – Fat deposits are converted into muscle. When combined with a healthy diet, weight loss is safe.
+>
+> **The waist is getting smaller** – Both male and female runners can reduce their waist size through running.
+>
+> **It builds stamina and confidence** – Running makes you fit. You are able to do more at work and in your free time without having to worry about your heart.
+>
+> **A healthier life begins** – The exercises should be carried out regularly over long periods of time, short exercise phases with long breaks only give little success.
+>
+> **Bruce Lee**, _Expressing the Human Body_
+
+For short-term endurance training its recommended that a fighter allows himself to be held by two people and must attempt to escape.
+
+## Speed
+
+Speed is the ability to move at maximum speed. In _taijutsu_, speed is a crucial factor, so the opponent doesn’t have time to react. With extreme speed and brief tension, it is possible to smash things that are harder than your own bones.
+
+There are two types of speed:
+
+1. **Reaction Speed**, which relies on reacting to an opponent’s action with lightning speed. This speed depends on the speed of command transmission between the cerebrum and the muscle.
+2. **Movement Speed**, which allows the fighter to perform a movement as quickly as possible; such as a throw or a punch. The most important thing here is the coordination of the muscles.
+
+## Strength
+
+This is the ability to overcome resistance through muscle contraction. A distinction is made between **maximum strength**, **speed-strength** and **strength endurance**.
+
+The right technique, speed, and reaction are indeed prerequisites for victory in a fight. In the case of equally strong opponents, however, it is the strength that counts. The maximum force is required, e.g. to lift and smash the opponent, strength endurance for lever or hold handles, and speed-strength for punches, kicks, and any kind of body movement (e.g. jumping).
+
+## Flexibility
+
+Flexibility is the ability to perform voluntary movements with large amplitude in the joints. An agile fighter will always pull the strings in a fight. Flexibility is often overlooked, and people lift weights and grow muscle mass, but flexibility suffers from this type of training.
+
+### Why Should You Stretch?
+
+> **Stretching Improves Health and Fitness** – When combined with proper strength training and aerobic exercises like running, stretching covers the last third of the three core areas of fitness.
+>
+> **Stretching Reduces Risk of Injury** – Most everyday and athletic injuries are sudden injuries (e.g. a fall, car crash, or collision with another individual) or overstretching of joints, muscles, or connective tissue, leading to muscle pain, dislocations or sprains. Fighters who stretch regularly have a 50 percent reduced risk of injury from such injuries.
+>
+> **Stretching is a good warm-up/cool-down exercise for other training** – An exercise before combat training improves neuromuscular coordination. And when you stretch right after your workout, you reduce the chance of muscle soreness and contribute to faster recovery.
+>
+> **Stretching improves athletic ability** – A flexible fighter is a better fighter and a flexible athlete is a better athlete. Could you imagine a gymnast with tight muscles? Any athlete who is flexible automatically has a physiological and psychological advantage.
+>
+> **Stretches are fun when done right** – Have you ever stretched out in bed when you wake up in the morning? That feels good, doesn’t it? In fact, a stretching exercise […] can be done before getting out of bed in the morning. This is a good way to prepare your body for the day.
+>
+> **Bruce Lee**, _Expressing the Human Body_
+
+The exercises of _jūnantaisō_ are suitable for improving flexibility.

+title: "Training of the Ninja"
+priority: 205
+date: 2006-03-28T16:17:00+02:00
+author: "Stefan Imhoff"
+excerpt: "You were born a Ninja and the countless techniques and endurance exercises were taught from an early age. In adolescence, martial arts and mental training were added to the curriculum."
+translationKey: "trainingOfNinjaPage"
+categories:
+ - training
+---
+
+## Ninja by Birth
+
+In earlier times you could not learn the profession of a Ninja, you became a Ninja by birth and died a Ninja. From early childhood, the toddler’s limbs were disjointed, creating the conditions that would later enable the Ninja to free himself from bondage. Even the young children of a Ninja learned to be aware of their surroundings. As they grew up, they were trained in the secret arts of their Ryū.
+
+## Training as a Child
+
+By the age of five or six, their childhood games began to take the form of exercise. They learned to train their balance and dexterity in a playful way. Balancing on thin poles that were hung higher and higher, they learned to twist, jump, sit and bend without losing their weight. They ran over mossy planks to train their balance or jumped over low bushes. Or they walked on _geta_ (wooden shoes) over ice surfaces.
+
+From the age of nine, physical condition and flexibility were trained. The children practiced rolls, jumps, and yoga-like movements. They learned to endure the bitter cold, to endure prolonged fasts, to breathe imperceptibly, and to harden themselves against torture.
+
+## Combat Training
+
+As they got older, they practiced hitting and kicking against bundles of straw.
+
+They learned the fundamental basic techniques of unarmed combat, and later the basics of sword fighting and staff fighting.
+
+As teenagers, they learned the use of their Ryū’s special weapons. Blade throwing, hidden weapons, rope, and chain techniques were trained.
+
+## Body Training
+
+They practiced swimming and underwater tactics and learned how to use nature to get information or hide. They spent countless hours lingering in tight spaces or hanging from trees, honing their patience, endurance, and resilience.
+
+They learned to move quietly and run great distances, jumping from tree to tree and roof to roof. Ninja should have been able to cover the 560 kilometers between Edo and Osaka in just three days. While that sounds like an exaggeration, Hatsumi insists that 110 kilometers a day were nothing out of the ordinary for a Ninja.
+
+What mattered most to the Ninja was speed, which allowed him to react at lightning speed.
+
+They later studied acting and psychology. By observing themselves and others, they learned to understand the human psyche and to use mental weaknesses and limitations to their advantage.
+
+They also learned how to make medicine and drugs, break into buildings, climb walls, hang from ceilings and lie under floors.
+
+They learned how to tie up an enemy, how to successfully escape, and how to create maps.
+
+## Mental Training
+
+In addition to physical training, mental development was of enormous importance. The body is only able to achieve incredible things in connection with the mind. One method of harnessing the mental powers was meditation and breathing. Breathing was calming and helped to banish disturbing thoughts. Calmness, perseverance, and conquering fear were decisive for the fight. Free from thoughts of victory or loss, the Ninja became capable of victory. The Ninja’s will was resolute, clear, and calm like a lake reflecting the moonlight on its surface. His actions were natural-relaxed. So he was able to defeat several attackers at the same time.
+
+They learned _kuji in_, magical finger signs with which they could attune themselves to the course of events and thus bring about changes. There were 81 finger signs in total. The Ninja used various elements of _shugendō_, _mikkyō_, and tantric teachings. _Kuji kiri_ was used to restore a Ninja’s confidence, to give them inner strength, or to help them in dangerous situations. Through the _kuji kiri_, Ninja were said to be able to sense hostility, heighten perception, and awaken in humans the instincts of wild animals.
+
+Ninja also used _saiminjutsu_, the art of hypnosis. Through their mental powers, the Ninja were able to solve any task.

+title: "Ukemi"
+priority: 345
+date: 2006-03-30T19:51:00+02:00
+author: "Stefan Imhoff"
+excerpt: "The first thing to learn in Ninjutsu is how to roll and fall properly. This is the only way to survive throws and jumps unharmed and to get out of or within range of the opponent in a fight."
+translationKey: "ukemiPage"
+categories:
+ - training
+---
+
+_Ukemi_ means _fall_ and encompasses any way of surviving a fall and falling to the ground unscathed. This also includes _kaiten_ (rolls) and other body movements. The Ninja uses the techniques when his legs are knocked over, when he wants to get out of reach of the opponent, or when he wants to evade attacks.
+
+Most martial arts neglect the ability to fall properly and then jump back up, continue fighting, or flee—although it would certainly be necessary. You don’t have a choice where to fight (unless you’re the attacker – and that’s **NOT** the point of Ninjutsu). This can be sitting in a train compartment, in a cramped broom closet, between tables and chairs in a canteen, or on a staircase.
+
+A Ninja must be able to jump off a truck, leap over a high wall, or throw himself with lightning speed – to avoid a bullet.
+
+First, the techniques are performed from a deep, squatting position in slow motion on a mat. Important points are lowering the center of gravity, exhaling, and body relaxation. Later, training takes place on a meadow, then on hard ground, asphalt, stairs, etc.
+
+## Zenpō kaiten – Forward Roll
+
+{% figure "Zenpō kaiten – forward roll" %}

+{% endfigure %}
+
+When falling backward, you hit the ground next to you with your arms and hands at an angle of 45°. One leg is bent and the sole of the foot is on the floor, the other leg is bent sideways inwards. The foot is first placed sideways with the outside flat on the floor. The chin is pressed against the chest so that the back of the head does not hit the ground.

+
+When falling sideways, you hit the ground sideways with your arm stretched out at a 45° angle and your palm on the ground. However, you do not fall on your back, but on the side of your body (hip, ribs, shoulder). The head is kept off the ground. The legs are extended straight up in the air together about 45° off the floor.

+
+
+{% endfigure %}
+
+_Nagare_ means to fall in such a way that there is no sound, soft and flowing like water. In doing so, you first approach the ground flat with your legs and lower your body’s center of gravity, and sometimes continue to roll straight away so that no noise can arise.

+
+
+
+{% endfigure %}
+
+The jumps in Ninjutsu are performed lightly and loosely so that they are almost silent. You practice jumping flat and far to the left, right, front, and back. _Ten_ means to jump high in the sky, _chi_ means to hunker down and drop the body to the ground.
+
+- forward (_mae_)
+- backward (_kōhō_)
+- to the right (_migi_)
+- to the left (_hidari_)

+- With two hands (_ryōte_)
+- without the use of hands (_mūte_)
+
+## Kiten – Hand Jump
+
+{% figure "Kiten – Hand Jump" %}
+
+
+
+{% endfigure %}
+
+From an upright position, arms straight, jump forward, backward, or to the side and down so that your body weight is over your bent arms. The arms push the body up and the bent legs are suddenly stretched out in the direction of the fall. The back is arched and the hips point in the same direction as the feet.

+
+## Kūhi – Air Jump
+
+{% figure "Kūhi – Air jump" %}

+priority: 400

+author: "Stefan Imhoff"
+excerpt: "The Ninja knew and mastered a vast arsenal of weapons, from simple small metal spikes and polearms to firearms and explosives."
+translationKey: "weaponsPage"
+categories:
+ - weapons
+---
+
+The weaponless _taijutsu_ is expanded by the possibility of being able to draw from a pool of numerous weapons. The Ninja have proven to be quick to adapt to modern times, improving or modifying weapons to make them more useful. For a Ninja, a weapon was no more than a tool to achieve his goal. In complete contrast to the Samurai, who paid special attention to their swords. For them, it was an outrage that Ninja sometimes simply sawed the blade shorter to be able to move better with the sword.
+
+The Ninja recognized the use of firearms early on, long before the first Daimyō mastered the use of firearms.
+
+Below is a _small_ – by no means exhaustive – selection of weapons favored by Ninja.
+
+## Aikuchi
+
+A small dagger very similar to the _tantō_ that was worn in the obi.
+
+## Ashikō
+
+{% figure "Ashiko" %}
+
+
+
+{% endfigure %}
+
+The counterpart to the _shukō_ is the _ashi kō_. A device similar to that on the hand was placed under the Ninja’s foot. Getting kicked made worse injuries that way, and climbing was far easier.
+
+## Baku hatsu gama
+
+{% figure "Baku hatsu gama" %}
+
+
+
+{% endfigure %}
+
+At the end of the _bakuhatsugama_, the Ninja attached explosives, poisons, or blinding powder. He threw it in the attacker’s face and then attacked him with the sickle.
+
+## Bisentō
+
+{% figure "Bisentō" %}
+
+
+
+{% endfigure %}
+
+The heavy halberd was introduced from China and required a different style of fighting than the _naginata_. It was far more massive, and in the hands of a strong warrior a formidable weapon.
+
+## Bō
+
+{% figure "Bō" %}
+
+
+
+{% endfigure %}
+
+One of the simplest weapons was probably the staff or stick. What is known today as the _bō_ is actually the _roku shaku bō_ with a length of approximately 182 cm. At first glance, the weapon doesn’t look very dangerous, but in the hands of a master, this all-purpose weapon is deadly. It could be used to stab or slash, and was also very effective against multiple opponents, making it a popular weapon among Ninja.
+
+## Bō shuriken
+
+Knife- or arrow-shaped, elongated _shuriken_.
+
+## Bō ken
+
+{% figure "Bō ken" %}
+
+
+
+{% endfigure %}
+
+Also _bokken_ or _bokutō_. Wooden sword made of heavy wood for practice. Usually even heavier than a sharp sword, it was a relief for the student when he got his _daishō_.
+
+## Bokken
+
+Also _bōken_ or _bokutō_.
+
+## Bokutō
+
+Also _bōken_ or _bokken_.
+
+## Chi giri ki
+
+A long stick and a chain with an iron weight on the end. Originally developed by farmers from the flail to defend themselves against attackers.
+
+## Daisharin
+
+{% figure "Daisharin" %}
+
+
+
+{% endfigure %}
+
+The _daisharin_ consisted of two wheels with an axle. The Ninja liked to use it to knock down larger groups of attackers or to use it as an improved staff.
+
+## Daishō
+
+_Big-small_, the designation for the pair of swords of the Samurai (_katana_ and _wakizashi_). Actually, only the Samurai were allowed to carry two swords, but a Ninja didn’t care, because as a non-noble he wasn’t allowed to carry weapons anyway.
+
+## Daitō
+
+_Big Sword_, a sword with a particularly long blade (between 60 and 180 cm).
+
+## Eiku
+
+Boat rudder, actually an Okinawan weapon. When the Ninja was in disguise as a fisherman, it was a good way to defend himself.
+
+## Endoku ken
+
+{% figure "Endoku ken" %}
+
+
+
+{% endfigure %}
+
+The Ninja also used throwing stars that released poisonous smoke when lit. In this way, one could force hidden enemies to reveal themselves.
+
+## Fukiya
+
+{% figure "Fukiya" %}
+
+
+
+{% endfigure %}
+
+The blowgun was popular because it could kill the enemy quietly. The bolts were poisoned, stifling every scream. Disguised as a flute, a blowgun could be carried around freely.
+
+## Fukumi bari
+
+Small darts that the Ninja spat in an attacker’s face.
+
+## Futokoro teppō
+
+{% figure "Futokoro teppō" %}
+
+
+
+{% endfigure %}
+
+The bronze pistol was popular with the Ninja because it was small and easy to conceal. Sometimes a bayonet was put on the gun.
+
+## Hanbō
+
+{% figure "Hanbō" %}
+
+
+
+{% endfigure %}
+
+The _half staff_ or stick, although very short at 3 feet, was a very effective weapon. The correct term is actually _sanshakubō_.
+
+## Hankyū
+
+{% figure "Hankyū" %}
+
+
+
+{% endfigure %}
+
+The _half staff_ or stick, although very short at 3 feet, was a very effective weapon. The correct term is actually _sanshakubōa_. The bow of the Ninja was far shorter than the bow of the Samurai. This made it easier to transport and hide. The shorter range usually didn’t matter much, as Ninja rarely needed to hit distant targets on the battlefield, most of the time only close targets. Explosives or incendiary materials were often attached to the arrows, especially since almost all buildings in Japan were made of wood. You could also use special arrows to cut ropes or create a howling sound that terrified enemies.
+
+## Hira shuriken
+
+Star-shaped flat throwable objects.
+
+## Hishi
+
+{% figure "Hishi" %}
+
+
+
+{% endfigure %}
+
+Dried water chestnuts served the same purpose as the _tetsubishi_ but were easier to obtain. In addition, they did not arouse suspicion, because in rural areas this plant was quite common.
+
+## Iga dama
+
+{% figure "Iga dama" %}
+
+
+
+{% endfigure %}
+
+This weapon could be used in a similar way to the _tetsubishi_, in addition to being thrown at enemies. They liked to be hidden all over the Ninja house to defend themselves against attackers.
+
+## Jirai
+
+Also _Uzume bi_.
+
+## Jō
+
+{% figure "Jō" %}
+
+
+
+{% endfigure %}
+
+The walking stick was a shortened form of _roku shaku bō_. It reached the waist or abdomen and could be used in a similar way to the staff. Its proper term is _yon shaku bō_.
+
+## Jutte
+
+Hand weapon with a hook that could be used to intercept a sword attack.
+
+## Kagi yari
+
+{% figure "Kagi yari" %}
+
+
+
+{% endfigure %}
+
+Also _kama yari_. Togakure-Ryū and kumogakure-Ryū Ninja often used the hook spear. You could get into trees, over walls, or onto ships. It was also possible to get from tree to tree in this way. Hidden on a high post, a victim could be caught with the hook and pulled up. It was also suitable for fishing, breaking down doors, or transporting luggage.
+
+## Kama
+
+{% figure "Kama" %}
+
+
+
+{% endfigure %}
+
+Short-handled sickle used in Asia to cut rice, corn, or sugar cane.
+
+## Kama yari
+
+Also _kagi yari_.
+
+## Kanzashi
+
+Fork-shaped hairpin. Often used as a weapon by the _kunoichi_.
+
+## Katana
+
+Samurai longsword, with a curved blade, manufactured in a complex forging process with different degrees of steel hardness, the best sword weapon in the world, with a blade length of 61 to 76 cm.
+
+## Kogai
+
+Sword pin or hairpin. The sword needle was actually a tool placed on the side of the _saya_. But it could also be used as a throwing or thrusting weapon.
+
+## Kongō
+
+{% figure "Kongō" %}
+
+
+
+{% endfigure %}
+
+Sanskrit _Vajra_. The scepter symbolizes the diamond, used by esoteric sects. Also served as a baton.
+
+## Kubotan
+
+Also _yawara_. Percussion weapon, in the shape of a cylinder. Suitable for grab handles or to apply pressure to joints. Similarities in usage in _kongō_.
+
+## Kusari fundō
+
+{% figure "Kusari fundō" %}
+
+
+
+{% endfigure %}
+
+Also _manrikigusari_. The chain was a useful weapon. It could be easily concealed and was even suitable for intercepting sword blows, binding opponents, choking them, or knocking them off their feet.
+
+## Kusarigama
+
+{% figure "Kusarigama" %}
+
+
+
+{% endfigure %}
+
+The _kusarigama_ was a popular weapon. Attached to a rice sickle was a chain one to two meters long. A weight was attached to the end of the chain. When attacked, a Ninja would throw the weight around the attacker’s blade, forcing the attacker to lower his weapon. After that, he attacked the enemy with the sickle.
+
+## Ku shaku bō
+
+Extra-long stick (270 cm).
+
+## Kyoketsu shoge
+
+{% figure "Kyoketsu shoge" %}
+
+
+
+{% endfigure %}
+
+Probably the Ninja’s most popular weapon was the _kyoketsu shoge_. A knife with a hook, an 18-foot (est. 5,49 m) long rope attached to the handle, and a steel ring at the end. The rope was often made of women’s hair since hair was particularly strong. With this weapon, the Ninja could control the opponent’s weapon, attack with the knife, block a sword stroke with the hook, or knock the enemy off their feet. He could climb and tie with the rope and firecrackers could also be attached to the steel ring to blind the enemy.
+
+## Kyū
+
+Also _yumi_.
+
+## Mamukugama
+
+{% figure "Mamukugama" %}
+
+
+
+{% endfigure %}
+
+With this weapon, a poisonous animal was attached to the end of the rope, such as a snake. This was thrown at the enemy and this made the fight much easier because the animal kept the enemy busy and maybe even killed them.
+
+## Manriki gusari
+
+Also _kusari fundō_.
A chain with the power of 10,000
. Chain with lengths from 40 to 400 cm and weights at the ends. Was developed in the 17th century by Masaki Toshimitsu, a gatekeeper in Edo, as a defensive weapon against swords.
+
+## Metsubushi
+
+When a Ninja was spotted, they were usually outnumbered. To escape safely, however, he used blinding powder to limit the enemy’s vision. In eggshells or nutshells, he kept a powder consisting of chemicals, ash, sand, iron filings, pepper, or nettle hairs. It could blind the enemy for a short time, or it could destroy eyesight forever.
+
+## Nageteppō
+
+{% figure "Nageteppō" %}
+
+
+
+{% endfigure %}
+
+These explosive grenades were thrown at the enemy by hand or with slingshots and worked on the same principle as a hand grenade does today.
+
+## Naginata
+
+{% figure "Naginata" %}
+
+
+
+{% endfigure %}
+
+The sword spear was a _sōhei_ weapon and the weapon of choice for Samurai women. They came in different forms (e.g. _nagamaki_), varying in blade-to-handle ratio, length, and blade thickness. It was a very effective weapon against mounted warriors, long as a spear and capable of severing limbs. After World War II it was used predominantly by women in the _naginatadō_.
+
+## Nagishi-shuriken
+
+Also _bō-shuriken_. Arrow-shaped projectiles that had a tassel at the end for flight stabilization.
+
+## Neko te
+
+{% figure "Neko te" %}
+
+
+
+{% endfigure %}
+
+The _kunoichi_ sometimes wore such a _cat’s claw_ on each finger. It could inflict terrible wounds on an attacker’s face.
+
+## Ninja tō
+
+{% figure "Ninja tō" %}
+
+
+
+{% endfigure %}
+
+Also _Ninjaken_ or _Shinobi katana_. The short sword was an important tool in Ninja equipment. It wasn’t pretty or valuable like the _tachi_ or _katana_ of the Samurai – it was useful. The blade was much shorter than that of the _katana_ or the _tachi_. So the Ninja could move better with it and use it in close combat. The blade was sometimes straight, but sometimes it was just a shortened _katana_. The _tsuba_ was not decorated with beautiful ornaments but mostly larger and made of simple steel, often angular. So you could use it as a climbing aid. The sword was carried at the side and only rarely (e.g. when climbing) over the back or stomach. Poisons, medicines, or chemicals were often hidden in the handle. The _saya_ could be used as a blowpipe or a breathing tube.
+
+## Ninja ken
+
+Also _Ninja tō_ or _Shinobi katana_.
+
+## Nodachi
+
+Very long Samurai swords with blade lengths of 100 to 180 cm, carried either on the back or by a servant.
+
+## Nuntebō
+
+A fishing spear is a tool used by fishermen, but it could also be used as a weapon.
+
+## Ōgama
+
+{% figure "Ōgama" %}
+
+
+
+{% endfigure %}
+
+The _ōgama_ was the battlefield version of the _kusarigama_. The chain was strong enough to knock horses off their feet. The sickle could pierce or cut through armor with ease.
+
+## Ono
+
+{% figure "Ono" %}
+
+
+
+{% endfigure %}
+
+The heavy war ax was brought from China after the fall of the T’ang Dynasty. It could smash through castle gates, knock warriors from their horses, or nullify any attack with a weaker weapon.
+
+## Ōzutsu
+
+{% figure "Ōzutsu" %}
+
+
+
+{% endfigure %}
+
+Togakure-Ryū Ninja used wooden cannons from very early on to be victorious in larger battles. This weapon was very effective against larger cavalry units or castle gates.
+
+## Ono gama
+
+A weapon consisting of a heavy war ax and a _kama_. Used by the _sōhei_ and the Ninja.
+
+## Roku shaku bō
+
+A _shaku_ was 30.3 cm. _Roku_ means six. The exact term for the _bō_.
+
+## San shaku bō
+
+A _shaku_ was 30.3 cm. _San_ means three. The exact term for the _Hanbō_.
+
+## Sembanshaken
+
+Term for a _shuriken_ with a hole in the middle.
+
+## Shaken
+
+_Shuriken_ with multiple prongs.
+
+## Shakuhachi
+
+Flute, 30.3 cm (1 _shaku_) long with eight (_hachi_) lateral holes. The flute was used by the _komusō_. Ninja liked to disguise their blowgun as a _shakuhachi_.
+
+## Shakujō
+
+{% figure "Shakujō" %}
+
+
+
+{% endfigure %}
+
+The staff of the priests was often used when a Ninja disguised himself as a monk. The staff has rings at the end, the sound of which the monk used to drive crawling animals off the path so that he could observe the law of non-killing and not accidentally step on an animal.
+
+## Shikomizue
+
+{% figure "Shikomizue" %}
+
+
+
+{% endfigure %}
+
+When a Ninja was on the move, he couldn’t always carry a sword openly with him. The _shikomizue_ was a sword hidden in a stick. Outwardly it looked like an ordinary staff, but that could be changed quickly.
+
+## Shinobi shobō
+
+{% figure "Shinobi shobō" %}
+
+
+
+{% endfigure %}
+
+The _shinobi shobō_ is a predecessor of today’s brass knuckles and works in the same way. The middle finger is put through a steel ring and the rest of the weapon is hidden in the fist.
+
+## Shinobi katana
+
+Also _Ninja tō_ or _Ninja ken_.
+
+## Shinobi kai
+
+Also _shinobi zue_.
+
+## Shinobi tantō
+
+{% figure "Shinobi tantō" %}
+
+
+
+{% endfigure %}
+
+The Ninja also used _tantō_, like the Samurai. But then they were mostly camouflaged or hidden in clothing. The _shinobi tantō_ was disguised as a short stick, similar to the _shikomi zue_.
+
+## Shinobi zue
+
+{% figure "Shinobi zue" %}
+
+
+
+{% endfigure %}
+
+Also _shinobi kai_. The Ninja liked to use staffs and sticks because carrying them was considered commonplace in Japan’s Middle Ages. Everyone carried a staff with them while hiking. Only the staves of the Ninja were modified. Usually, they were hollow, and inside were hidden knives, poisons, blinding powder, or chains with weights. When a Ninja was attacked, he quickly opened the staff’s cover and an iron ball attached to a chain flew out and the Ninja was able to use it to knock the enemy off his feet. Or he hurled poison, blinding powder, or other weapons at him. This is how a normal walking staff quickly turned into a spear, poison splatter, or morning star.
+
+## Shukō
+
+{% figure "Shukō" %}
+
+
+
+{% endfigure %}
+
+Also _tekagi_. A terrible weapon is the _shukō_. A pointed iron prong was attached to a kind of leather arm ring, whereby the Ninja turned his hand into a tiger claw. The spikes could inflict terrible wounds on the attacker’s face. With this weapon, the Ninja could also _take swords_, i.e. stop the sword strike. At the same time, the Ninja could climb up walls or trees better. The counterpart for the feet was called _ashi kō_.
+
+## Shuriken
+
+{% figure "Shuriken" %}
+
+
+
+{% endfigure %}
+
+The most famous weapons were the throwing blades. As _hira shuriken_ in star form or as _bō-shuriken_ in dagger form. Each weapon required its own throwing technique. The throwing blades could be poisoned and also used in close combat. The _senban shaken_ was the typical throwing star of Togakure-Ryū. It had four points and looked like a diamond. There was a hole in the middle. The sides were ground sharp. The throwing star was very thin and light, so nine could always be carried together in the inside pocket.
+
+## Sodezutsu
+
+{% figure "Sodezutsu" %}
+
+
+
+{% endfigure %}
+
+The smaller brother of the _ōzutsu_ was the _sodezutsu_. This cannon could be fired from the hand and was a forerunner of rifles.
+
+## Tachi
+
+Old longsword with a blade 61 to 76 cm long. The _tachi_ was usually more curved at the handle than the _katana_ and was fastened horizontally with the blade down on the belt in front of the body. The _katana_ was tucked into the belt with the blade up. Initially used as a battle sword, later mostly only for ceremonial occasions.
+
+## Tanegashima
+
+{% figure "Tanegashima" %}
+
+
+
+{% endfigure %}
+
+Also _teppo_. The Ninja were probably the first to see the utility of the arquebuses that the Portuguese introduced to Japan. Long before the weapon was used in battle, it was used in assassination attempts by the Ninja.
+
+## Tantō
+
+Dagger. The blade was less than 30 cm long. The _tantō_ was used as a defensive weapon by many people from all walks of life.
+
+## Tekagi
+
+Also _shukō_.
+
+## Tekkō
+
+Brass knuckles, exactly like modern brass knuckles in appearance and function.
+
+## Teppō
+
+Also _tanegashima_.
+
+## Tessen
+
+{% figure "Tessen" %}
+
+
+
+{% endfigure %}
+
+The War Fan was a popular weapon because it didn’t look like a weapon at first glance. With the fan, the outer parts were made of steel, sometimes it wasn’t even a fan at all but just a piece of steel in the shape of a fan. With this weapon, you could inflict pain on the joints or control it with it.
+
+## Tetsubishi
+
+{% figure "Tetsubishi" %}
+
+
+
+{% endfigure %}
+
+When a Ninja was being pursued, he would scatter a handful of these iron metal spikes on the ground. Since straw sandals were worn in Japan, it was extremely painful to step on the thorns and a pursuit could not continue. What was brilliant about this weapon was that no matter how you threw it, there was always a spike sticking up. Also occurs naturally in nature (_hishi_).
+
+## Tetsubō
+
+{% figure "Tetsubō" %}
+
+
+
+{% endfigure %}
+
+This weapon was probably used all over the world and is one of the most primitive. Steel spikes were attached to a mace to increase effectiveness.
+
+## Toami
+
+{% figure "Toami" %}
+
+
+
+{% endfigure %}
+
+The web was used by the Ninja to defend themselves against a variety of attackers. In the fishing villages, it was an everyday tool and was hardly noticed. It could also be set up in forests or corridors as a trap.
+
+## Tonki
+
+Also _shuriken_.
+
+## Torinawa
+
+A pointed shaft attached to a chain or string and had a weight at the end.
+
+## Tori no ko
+
+firecrackers. Imported early from China. Only used to distract and confuse. Later, after the introduction of black powder, explosives were also manufactured.
+
+## Uzume bi
+
+Also _jirai_. These land mines were buried deep underground. An enemy who stepped on the box set the firing mechanism in motion and was killed or seriously wounded by an explosion.
+
+## Wakizashi
+
+_Companion of the Belt_, a short sword resembling its larger image the _katana_. Together with the _katana_ formed the _daishō_.
+
+## Wakizashi teppō
+
+{% figure "Wakizashi teppō" %}
+
+
+
+{% endfigure %}
+
+Concealed inside a traditional short sword was a pistol that could fire one shot.
+
+## Yon shaku bō
+
+A _shaku_ was 30.3cm. _Yon_ means four. The exact term for the _jō_.
+
+## Yari
+
+{% figure "Yari" %}
+
+
+
+{% endfigure %}
+
+The Japanese spears were designed to stab and were rarely thrown. With its small point, one could easily fit between the plates of the Samurai armor. The tips were mostly two- or three-sided. It was usually 200 to 350 cm long. Oda Nobunaga used _yari_, some 640 cm long, to protect his _teppō_ soldiers against cavalry.
+
+The Ninja often used the _yari_ to high jump over walls or people.
+
+## Yawara
+
+Also _kubotan_.
+
+## Yumi
+
+Also _kyū_. Arrow (_ya_) and bow (_yumi_). The Japanese bow was made from different layers of wood or bamboo and is approximately 220 cm long. It is one of the few bows in the world with an asymmetrical shape. The arrow rests in the lower third.

+## 1999
+
+### December 22, 1999
+
+My Ninjutsu website goes live on December 22, 1999. First on a shared space without its own domain. It later runs under two different domains before getting its final name: **kogakure** (木隠, Japanese
hidden behind leaves and trees
).
+
+I still remember looking in a very thick Japanese dictionary for a term that didn’t exist on the internet yet and that also has a meaning.
+
+The theme had _of course_ animated Ninja stars, garbled font, and a page counter.
+
+
+
+---
+
+## 2001
+
+### January 2001
+
+The site actually started out as just a collection of notes, but slowly grew into a larger site over the next two years. In January 2001, work on the website was almost complete. By that time, I had put a ridiculous amount of hours into researching and writing the articles. I had also created numerous intricate 3D models of weapons, tools, and techniques in _Poser_ and _3d Studio Max_.
+
+
+
+---
+
+## 2002
+
+### January 2002
+
+In January 2002 I put a new design (version 2) of the website online. The first website only used a few table cells to create the layout, this version relied on the spacer GIFs that were common at the time, with which you designed the borders of boxes.
+
+I had already created the second version in parts with PHP in order to only have to maintain recurring parts once.
+
+At that time I also had a guest book, a forum, and a counter, as was common on many sites at the time. I created the navigation with JavaScript and it was very difficult to use. I also used Flash at times for a _great_ light effect and a pure Flash home page with music and animations.
+
+In addition to a questionable selection of fonts and _hip_ style, I introduced bamboo as a trademark of my website for the first time.
+
+
+
+---
+
+## 2004
+
+### September 2004
+
+In September 2004 I created version 3 of the website. As I slowly gained more understanding of design, the website didn’t look horrible anymore. Instead of a huge header image, I was now using a stylized bamboo that I _found_ somewhere on the Internet due to a lack of manual skills and then modified it with various photo filters and changes to protect against copyright infringement until it could pass as my _own creation_.
+
+I also ordered a seal stone, carved by a Japanese artist, I ordered over the internet. I remember it took a lot of effort for him to find the characters of kogakure in the Chinese seal script.
+
+Technically, I used a semantic CSS layout here for the first time, which used floats to organize the individual columns on the page.
+
+
+
+---
+
+## 2006
+
+### April 30, 2006
+
+Two years later, CMS (Content Management Systems) were everywhere and I bought a license from [ExpressionEngine](https://expressionengine.com/) to run my blog with it.
+
+For version 4 of my website, I had created a completely new bamboo in Adobe Illustrator using the gradient mesh tool.
+
+There have also been improvements to the fonts and the overall design has become lighter and fresher.
+
+
+
+### Aug 25, 2006
+
+#### Nomination for the Web Design Book
+
+The website was nominated for the **Webdesignbook**. The web design book was a project that honored impressive designs. The nominated pages had to be implemented in a table-less layout, with valid markup and CSS. Once a year, 150 websites were selected by a well-known jury and published sometime in the fall of the year in book form with around 248 pages. In addition, the book contained interviews with designers, articles about designers, designs were organized by color, style, and author. That year the jury consisted of Andy Budd, Tammie Lister, John Oxton, Marco van Hylckama Vlieg, James Archer, Kyle Neath, Chris J. Davis, and Thomas Silkjær.
+
+### October 29, 2006
+
+#### Bujinkan at _World of Wonders_
+
+On Sunday, October 29, 2006, at 7:00 p.m., a television report about the Ninja was broadcast on RTL2 in the program **Welt der Wunder**.
+
+The World of Wonders team visited Hatsumi Sensei in Japan and recreated historical battles and Ninja missions. A few German Bujinkan Dōjō assisted the film crew both in front of and behind the camera.
+
+I had the pleasure of providing the editors with theoretical knowledge before the film work began.
+
+---
+
+## 2007
+
+### February 25, 2007
+
+#### 100,000th visitor
+
+On January 25, 2007, my website had reached its 100,000th visitor since I started counting in October 2005. A total of 100,015 visitors had viewed 497,349 pages since then.
+
+The posts about a Ninja on RTL2 (**Welt der Wunder**) and PRO7 (**Galileo Mystery**) generated top ratings. Interest in the articles was many times greater among visitors after the _Welt der Wunder_ contribution than among visitors to the _Galileo Mystery_ contribution.
+
+---
+
+## 2008
+
+### April 24, 2008
+
+Version 5 of my website is going live. This time it was only a small visual change, but the technical part was completely new.
+
+I used a web framework for this for the first time, which meant that I had to write every single line myself and, in addition to templates, also had to take care of the database, controller, and various other things. At that time, the Python web framework [Django](https://www.djangoproject.com/) convinced me, so I taught myself Python and built the website from scratch. Django’s admin interface in particular was a particular highlight back then.
+
+
+
+---
+
+## 2010
+
+### March 10, 2010
+
+#### The Warning
+
+Since I had a small collection of sayings and quotes on my website, I was warned by **Karl Valentin**’s heirs for copyright infringement. I had to sign a cease and desist letter and my lawyer was able to avert major damage. I paid nothing to the plaintiffs.
+
+For the first time, I came into contact with really terrible people whose whole purpose in life was to make life difficult for other people. Since Karl Valentin’s works entered the public domain in 2018, the heirs wanted to earn as much as possible before this source dried up.
+
+It became clear to me that these were **commercial warnings** when my lawyer informed me that his law firm in Hamburg alone represented four clients on this one said sentence.
+
+Unfortunately, after this experience, I was forced to remove the sayings from the website completely, because I could not determine for each saying without a doubt whether the author had been underground for more than 70 years.
+
+---
+
+## 2015
+
+### April 7, 2015
+
+Five years later the sayings were back (I had checked every single author and removed all newer authors). Along with the sayings came a completely new design and version 6 of my website.
+
+I had said goodbye to Django as I was involved with Ruby professionally and Python was just a hobby. It was also a lot of work to keep such a website up and running.
+
+Luckily, many other developers had realized this as well, and more and more people had started converting their websites and blogs to static pages. There is an almost unlimited number of [Static Page Generators](https://www.staticgen.com/) that allow you to work with templates, logic and data and still end up throwing out pure static HTML pages. Also, no one can hack the website. And no database or expensive and complicated server software is required, but the sites can be hosted almost anywhere and scale fantastically. Even a few thousand hits per second won’t distress a server.
+
+I used [Jekyll ](https://jekyllrb.com/) as a page generator, used [PostCSS](https://postcss.org/) for my CSS, [Browserify](http://browserify.org/) for my JavaScript and [Gulp.js](https://gulpjs.com/) as a build tool.
+
+The entire website was mobile-optimized and ran on any device.
+
+I recreated the bamboo from scratch in [Affinity Designer](https://affinity.serif.com/designer/) to embed directly into the page as an SVG (and the gradient tool was not supported by SVG).
+
+
+
+---
+
+## 2017
+
+### June 27, 2017
+
+After six months of work, I published an **eBook** of kogakure.
+
+I used **GitBook** to write my book and also for hosting and delivering the eBook variants.
+
+As part of the revision I fixed numerous errors, looked over each article, added new images and replaced graphics with SVG wherever possible.
+

+
+Since Jekyll renders very slowly and I had already replaced my [private website](https://www.stefanimhoff.de) with the static page generator [Hugo](https://gohugo.io/), it was just the next logical step to do the same for kogakure.de.
+
+At the same time, I was able to rework the whole website, make some minor graphic changes and completely redesign the homepage.
+
+I was also able to use the [CSS Grid Layout](https://gridbyexample.com/) on a larger scale for the first time. Working with this new CSS standard for page layouts was incredibly fun.
+
+The website had now a service worker and could be viewed even without an internet connection.
+
+
+

+
+## 2022
+
+### February 9, 2022
+
+In February 2022 I created a new design for my website. I used the Japanese design based on the aesthetic of _Shibui_ developed by me in 2020. The design was originally developed for my [private website](https://www.stefanimhoff.de), later I also used it for my [photo blog](https://hamburg.stefanimhoff.de). I reused basic things like the grid, the color palette and typography again, but adjusted each of the pages a bit.
+
+Technically, the page is now created with [Eleventy](https://www.11ty.dev/), uses CSS Grid Layout and CSS Custom Properties.
+
+
+
+
+
+### February 25, 2022
+
+For the first time in the more than 20-year history, 木隠 is now also translated into English. I would like to make the work accessible to a larger readership.

+
+This online book only exists because in 1999 two things came together at the same time: my interest in Ninjutsu and my interest in web design.
+
+When I first came into contact with Ninjutsu in the 90’s, information was very difficult to find. There were very few Dōjō in Germany, none of them within reach for me. Books were scarce, and the few books that were available were very difficult to obtain (I had to pay in advance without ever seeing them and wait weeks or even months for delivery). At that time I collected every piece of information that fell into my hands and made notes. This collection of notes became what this website is today.
+
+I use Hepburn spelling for Japanese words, except for a few terms that are so commonplace (e.g. Ninja, Ninjutsu or Samurai). If a term is unclear, you will certainly find an entry in the glossary that describes in more detail what it is about. I don’t pluralize Japanese words, even if it’s allowed. I just think it sounds awful. A Ninja. Two Ninja. Lots of Ninja.
+
+### History
+
+This chapter contains sections on the origins of Ninja and Ninjutsu, fighting schools, biographies, the largest and most famous schools, stories of conflicts in the Ninja heartland, the decline of the Ninja, and recent history.
+
+### Organization & Training
+
+This chapter deals with the structure within a Ninja school and the training of the Ninja.
+
+### Body Training
+
+Everything about the physical abilities, the fighting positions, fall school, sneaking techniques and similar topics can be found in this chapter.
+
+### Weapons & Tools
+
+The Ninja had a vast arsenal of weapons, gear, poisons, medicines, and food, which I’ll explore in more detail in this chapter.
+
+### Mental Powers
+
+In this chapter I describe Ninja spiritual powers, philosophical and religious concepts.
+
+### Strategy & Tactics
+
+The numerous strategies of espionage, warfare, escape techniques, techniques of hiding and disguise are examined in more detail in this chapter.
+
+### The Legacy of the Ninja
+
+The biographies of the grandmasters Takamatsu and Hatsumi, the organization Bujinkan, as well as the 9 schools of Bujinkan are described in more detail here.
+
+### Rules & Philosophy
+
+In this chapter, a few more rules and philosophies are described at the end.
+
+### Appendix
+
+The attachments contain a [Chronology](/en/chronology/) of this website from its inception to the present, including screenshots of old versions’ designs. There is also a [Downloads](/en/downloads/) page where you can download the eBook and other useful stuff. [Recommendations](/en/recommendations/) contains book and film recommendations from the subject areas Ninja, Samaurai, Bujutsu, Martial Arts, Philosophy and Asia. The [Glossary](/en/glossary/) contains over 500 words from the field of Ninjutsu and martial arts including the Japanese characters. [Colophon](/en/colophon/) contains information about this website, FAQs, contact information and technical information.

Kolophon
-
- Dies ist 木隠. Seit 1999 kann man hier Artikel, Textsammlungen und
- Übersetzungen zu Themen rund um die japanischen Schattenkrieger und Spione,
- die Ninja, und deren Kampfkunst Ninjutsu lesen.
-
-
-
- Die Idee dazu wurde von Stefan Imhoff, einem Designer, Entwickler und
- Kampfkünstler aus Wolfsburg (heute aus Hamburg) entwickelt und umgesetzt.
-
-
-
-
-
Was bedeutet kogakure?
-
- Der Name kogakure (木隠) ist japanisch und bedeutet wörtlich übersetzt in
- etwa Verborgen hinter Blättern und Bäumen
.
-
-
-
- Ich habe diesen Namen in Anlehnung an das Buch des Samurai Tsunetomo
- Yamamoto, Hagakure (Verborgen unter Laub
) und der ältesten Schule im
- Bujinkan, Togakure (Verborgen hinter einer Tür
) gewählt.
-
-
-
-
-
Warum gibt es dieses Buch?
-
- Seit Anfang der 90er, ursprünglich wahrscheinlich durch die Teenage Mutant
- Hero Turtles auf das Ninjutsu gestoßen, interessierten mich die Ninja und
- ihre Gedankenwelt.
-
-
- Damals war das Bujinkan in Deutschland nur spärlich zu finden, eine
- Trainingsmöglichkeit nahezu unmöglich zu finden. Auch die erhältliche
- Fachliteratur war mehr als dürftig.
-
-
- Auf der Suche nach Wissen, Hintergrundinformationen und Informationen
- sammelte sich im Laufe der Zeit eine Notizsammlung an, die in diesem Buch
- verarbeitet wurde.
-
-
- Dieses Buch erhebt keinen Anspruch auf Vollständigkeit, oder nach absoluter,
- belegbarer, geschichtlicher Beweise. Sie soll allen bugeisha (Kriegern)
- helfen, mehr über die Weisheiten dieser über tausend Jahre alten Kunst zu
- erfahren.
-
-
-
-
-
-
-
FAQ
-
- -
-
Wo kann ich trainieren?
-
- Um ein Dōjō für Bujinkan Budō Taijutsu zu finden, solltet ihr am besten
- in einer Suchmaschine nach Bujinkan in Verbindung mit
- einer Stadt in eurer Nähe suchen. Aber mit Sicherheit wird es keine so
- gute Abdeckung mit Dōjō wie bei Jūdō oder Karate geben. Auf der
- Bujinkai-Seite gibt es eine sehr umfangreiche
- Dōjō-Liste.
-
-
- Ich selbst habe kein eigenes Dōjō und biete
- kein Training an. Kogakure ist kein Kampfkunst-Stil, sondern
- der Name des Buches.
-
-
- -
-
Was für Bücher gibt es?
-
- Die Auswahl an Fachbüchern über Ninja und Ninjutsu ist sehr groß. Der größte Teil ist jedoch auf Japanisch oder Englisch. Am
- besten einfach mal in meine
- Empfehlungen schauen.
-
-
- -
-
Welche Bücher kannst du mir empfehlen?
-
- Zuerst lege ich euch die Bücher von Dr. Masaaki Hatsumi ans
- Herz. Andrew Adams Buch Ninja ist gut, um einen
- Gesamtüberblick zu bekommen. Stephen K. Hayes hat sehr viele
- philosophische Aspekte in seinen Büchern (z. B. Tendai, Shugendō,
- Mikkyō), da ihn dies persönlich sehr interessiert, er ist sogar genau
- wie Takamatsu zum Mönch des Tendai ernannt worden.
-
-
- -
-
Wo bekomme ich Bücher über Ninjutsu her?
-
- Seit es Buchversender wie z. B.
- Amazon
- gibt, sollte es keine Problem mehr darstellen, Bücher aus dem Ausland zu
- bekommen. Auf der Seite Empfehlungen habe
- ich eine Liste von Büchern und Filmen zusammengestellt, die ich
- empfehlen kann.
-
-
- -
-
Ich möchte auf eine Seite verlinken. Was ist zu beachten?
-
- Es ist generell untersagt die Verlinkung in einem Frame zu
- verwirklichen, bei dem die Website nicht mehr als Urheber erkennbar ist.
- Du darfst gerne auf jede Seite dieser Domain verlinken.
-
-
- Bilder, Photos und andere Medien dürfen
- nicht direkt verlinkt werden, wohl aber heruntergeladen und auf
- eigene Server gestellt werden (so lange die Regeln der
- Creative Commons Lizenz
- eingehalten werden).
-
-
- -
-
Sind Übersetzungen der Texte erlaubt?
-
- Übersetzungen der Texte in andere Sprachen sind grundsätzlich erlaubt,
- solange dem Text eine Quellenangabe beigefügt wird. Bitte schicke mir
- einen Link, wo die Übersetzung publiziert wird.
-
-
- Eine kommerzielle Nutzung, in welcher Form auch immer, ist nur mit
- schriftlicher Genehmigung möglich.

-
-
-
- ♥︎
- Spenden
-
-
- Dieses Buch ist kostenlos, werbefrei und hat mich im Laufe der Zeit viele
- hundert Stunden Arbeit gekostet.

- Wenn es dir gefallen hat, freue ich mich über Lob und Anerkennung. Du kannst
- mich unterstützen, indem du etwas aus meinen
- Empfehlungen kaufst oder mir eine kleine Spende
- zukommen lässt.
