Dr. Masaaki Hatsumi was born in Noda City, Chiba Prefecture on December 2, 1931. He graduated from Meiji University in Tokyo, with a major in theatre studies, and now in the director of his own chiropractic clinic in Noda City.

In the 1950s and 1960s, Dr. Hatsumi continuously travelled across Japan to study with Toshitsugu Takamatsu, of Kashiwara City, Nara Prefecture, from whom he received his initiation into the life ways of the ninja. Dr. Hatsumi later inherited from his teacher the authority and position of soke (grandmaster) in the following Japanese martial traditions:
