Training
Ninja training consists of 18 disciplines called "ninja juhachi kei."

Seishinteki kyōyō (精神的教養)

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.
