Masaaki Hatsumi

He graduated from Meiji University[?] in Tokyo, with a major in theater studies, and later opened his own chiropractic clinic in Noda City[?].

From his childhood he studied many martial arts, including Judo and western boxing. But it was first when he met his teacher Toshitsugu Takamatsu[?] that he found the arts that he wanted to dedicate his life to.

From Takamatsu[?] he inherited the position of Soke[?] (Grandmaster) of 9 Ryu[?] (schools of martial art):

• Togakure Ryu Ninpo[?] Taijutsu - The Hidden Door School
• Gyokko Ryu Koshijutsu[?] - The Jeweled (or pearl) Tiger School of "bone finger art"
• Kukishinden Ryu Happo Hikenjutsu[?] - The Nine Demon School of "eight secret weapons arts"
• Koto Ryu Koppojutsu[?] - The Tiger Knocking Down School of Bone Structure Art
• Shinden Fudo Ryu Dakentaijutsu[?] - The Immovable Heart School of "hard weapon body art"
• Takagi Yoshin Ryu Jutaijutsu[?] - The High Tree and Awakened Heart School
• Gikan Ryu[?] Koppojutsu[?] - The Truth, Loyalty, and Justice School of Bone Structure Art
• Gyokushin Ryu[?] Ninjutsu - The Jeweled (or pearl) Heart School
• Kumogakure Ryu[?] Ninpo[?] - The Hiding in the Clouds School

To facilitate the teaching of these schools he created the Bujinkan organization, that teaches his amalgation of all the schools.
