Dr. Masaaki Hatsumi is the grandmaster of the martial art called Budo Taijutsu. The organization that oversees this martial art is called the Bujinkan.
Budo Taijutsu is not a single martial art, but integrates 9 different martial arts that Hatsumi-sensei inherited from his teacher, Toshitsugu Takamatsu. Each of these martial arts has its own tradition and methods. By bringing them under a single integrated martial art, Hatsumi-sensei has not only preserved these traditional arts, but created something even more significant: Budo Taijutsu.
