Hatsumi-sensei was born on December 2, 1931 in Chiba prefecture, Japan. He studied Asian and Western martial arts (including judo, karate, and boxing), fine arts, soccer, gymnastics, acting and dancing. At the age of 27 he began to study the martial art traditions taught by Toshitsugu Takamatsu.
As Takamatsu's last and only "true" student, in 1972, Hatsumi-sensei succeeded to Takamatsu-sensei's nine schools of ancient Japanese martial arts. He founded the Bujinkan Dojo, where he teaches the martial art derived from these nine traditions, which he has named "Budo Taijutsu."
