Ninjitsu

Ninjutsu (忍術) is a collection of techniques originally practiced for espionage purposes. It includes methods of gathering information, non-detection, avoidance, and misdirection techniques. Ninjutsu can also involve training in disguise, escape, concealment, archery, medicine, and explosives.

Practitioners of ninjutsu have been seen as assassins for hire, and have been associated in the public imagination with other activities which are considered criminal by modern standards. Even though it was influenced by Chinese spying techniques and the strategic principles of Sun Tzu, ninjutsu is believed by its adherents to be of Japanese origin. One version is that the basis of ninjutsu was taught to a Japanese household who fled to the mountains after losing a battle. There they mixed with a varied lot of people including the descendants of refugees who had fled China. Later, the skills were developed over 300 years to create ninjutsu.

Although the popular view is that ninjutsu is the art of secrecy or stealth, actual practitioners consider it to mean the art of enduring – enduring all of life’s hardships. The character nin carries both these meanings, and others.
