The Bujinkan is an international martial arts organisation based in Noda, Japan and headed by Masaaki Hatsumi. The combat system taught by this organisation comprises nine separate ryuha, or schools, which are collectively referred to as Bujinkan Budo Taijutsu.
The Bujinkan is most commonly associated with Ninjutsu. However, Masaaki Hatsumi now uses the term Budo (meaning martial way) as he says the ryuha are descended from both historical Samurai schools that teach Samurai martial tactics and Ninjutsu schools that teach Ninja martial tactics.
Bujinkan unarmed and armed movement focus on the efficient use of the entire body (“taijutsu”) to achieve maximum effectiveness. It is not a sport. Rather, training is centred on Jissen Gata or Combat Fighting.
