Bujinkan is an international martial arts organization based in Noda, Japan. Founded in 1974, and headed since then by Dr. Masaaki Hatsumi, it teaches Bujinkan Budō Taijutsu, the nine traditional Ryūha (schools, or martial arts lineages) he inherited from his master, Toshitsugu Takamatsu before his passing in 1972. The Densho (scrolls containing the techniques, forms and movements), and the way of using them have been transmitted for over 900 years from generation to generation through an unbroken lineage of Grandmasters.
