The Bujinkan is an international martial arts organization based in Japan and headed by Masaaki Hatsumi. The combat system taught by this organization comprises nine separate ryūha, or schools, which are collectively referred to as Bujinkan Budō Taijutsu. The Bujinkan is most commonly associated with ninjutsu. However, Masaaki Hatsumi uses the term Budo as he says the ryūha are descended from historical samurai schools that teach samurai martial tactics and ninjutsu schools that teach ninja tactics.

Naginatajutsu is the Japanese martial art of wielding the naginata (長刀). The naginata is a weapon resembling the European glaive and the Chinese guan dao. Most naginatajutsu practiced today is in a modernized form, a gendai budō, in which competitions also are held.
