Ninjutsu

**Ninjutsu** (**忍術**) is the traditional Japanese art of stealth, camouflage, and sabotage, developed in feudal times for espionage and now practiced as a martial art.

## Training

Ninja training consists of 18 disciplines called "ninja juhachi kei" (忍身十八形).

### Taijutsu (体術)

Unarmed combat, ninja hand-to-hand combat.

### Kenjutsu (剣術)

Sword techniques, swordsmanship.

All ninja must be able to fight with a sword. The training is tiring and difficult, but ninja have to learn to persevere. To be a skilled swordsman, training is essential. The katana is not an easy weapon to master. The katana is a popular ninja weapon, especially in the training arena (tameshigiri). It requires excellent balancing and fine motor skills. For those who know the true value of it, they use it for fine slicing and dicing. The simple blade is sharp and reliable. While it won't win any beauty contests, it cuts clean and gets the job done.

* **En-yo:** The en-yo move is more about timing and precision than power. Sounds and vibrations identify the attack, and instead of hacking through the limb, the first strike imparts an injury (slash to arm) just a few inches below the elbow. The sword’s razor sharp blade easily slices through the soft tissue of the attacker’s arm. This opens up his defense, and provides the ninja a clean opportunity to deliver the kill stroke, a powerful shot to the top of his head (fatal blow to the skull, velocity of katana = 55 mph) The ninja senses the enemy from behind.

### Bōjutsu (棒術)

Stick and staff fighting techniques.

The martial art of using a staff weapon involves slashing, swinging, and stabbing with the staff. Simple but effective, this basic ninja weapon is useful in one-on-one combat. The large wooden pole is a powerful defensive weapon, especially in the hands of a skilled fighter. This fighting staff can be used for blocks, strikes, and sweeps at an enemy.

### Sōjutsu (槍術)

Spear fighting techniques.

In the hands of a trained ninja, the spear is a lethal weapon of deadly accuracy. A fast and accurate weapon in the hands of a ninja. This weapon can be thrown at enemies. Long and very heavy, these spears can only be wielded by the strongest ninja.

### Kayakujutsu (火薬術)

*"Ninjutsu employs explosive powders."
"As weapons?"
"Or distractions. Theatricality and deception are powerful agents. You must become more than just a man in the mind of your opponent."*
—Ra's al Ghul and Bruce Wayne in *Batman Begins*
Fire and explosives, pyrotechnics, the art of gunpowder.

Ninja use gunpowder in a pyrotechnical way in order to secure their safe exit. They also use firearms. Ninja use materials that are capable of undergoing self-contained exothermic or chemical reactions for the production of, among other things, smoke, gas, or explosions. They can also make improvised explosive weaponry. Ninja disorient enemies and go in for the attack.

### Hensōjutsu (変装術)

Disguise and impersonation.

Ninja use disguises to infiltrate enemy territory, pass as the enemies' trusted allies, and impersonate to infiltrate. They often infiltrated enemy territory dressed as farmers/peasants. Often, they were armed with tantō (短刀), and in the event they were caught, a ninja would lash out with a surprise tantō attack. They were pre-eminent street fighters.

### Shinobi-iri (忍び入り)

### Kuji-kiri (九字切り)

In *Enter the Ninja* (1981), the Kuji-kiri is also known as the nine levels of power.

In *Overwatch*, Genji speaks the nine syllables of the Kuji-in (臨兵闘者皆陣列在前) and translates to "Preside. Warriors. Fight. Person. Altogether. Formation. Align. At. Front," or "Presiding warriors and fighting personnel, all align your formation up front." Another translation is "May all those who preside over warriors be my vanguard."

According to Gaijin Goombah, the kuji-kiri is an adaptation of Buddhist hand seals.
