Ninjutsu in common conception refers to martial arts, practices, and techniques descended from the mythical ninja. It seems to have developed as a response to the dominant samurai class between the 13th and 16th centuries in the provinces of Iga and Kōka, Shiga, Japan. Ninjutsu encompasses techniques from several centuries-old Japanese martial arts schools. The Ninjutsu program includes a wide variety of techniques, ranging from unarmed movements to an extensive collection of kata with weapons. This application presents hundreds of techniques, including strikes (punches, kicks, and headbutts), throws and chokes, defenses against holds (chest, face, back), defenses against grappling maneuvers (wrist or clothing grabs), as well as evasions. Each technique is presented from different angles, including a multi-view option, slow-motion, and professionally shot close-ups combined with a user-friendly interface. Various techniques are demonstrated by Yossi Sheriff, a 5th dan level Ninjutsu expert. He has been practicing this discipline for over thirty-five years and teaching it for twenty years.
