Ninjutsu, perhaps the least understood martial art of Japan, is an ancient fighting style emphasizing naturalness of movement, responsiveness to one's adversary, and absolute practicality. In feudal Japan, ninja were feared for their skill in espionage and assassination. Masters of weaponry, stealth, and martial techniques, ninja warriors were often credited with supernatural powers because of the near-invincibility of their unique and deadly art.
