The Bujinkan Dojo 武神館道場, or "Warrior God Training Hall," was organized in the early 1970's by Hatsumi Masaaki Sensei.  This organization is comprised of nine distinct schools of ancient Japanese martial arts, with traceable histories from the ninth century and earlier.  Hatsumi Sensei inherited these ryu ha from his teacher, the late Takamatsu Toshitsugu in 1972.  The nine schools of the Bujinkan are listed below.

• Togakure Ryu Ninjutsu, Founded by Daisuke Nishina in the Late 1100's;
  
• Gyokko Ryu Koshijutsu, Founded by Tozawa Hakunsai in the Mid 1100's;

The Bujinkan martial arts emphasizes natural and relaxed body movement to generate power.  Taijutsu (unarmed) "body skill" uses the entire body in a natural way to harmonize and amplify simple movements, rather than relying solely on brute force or speed.  The subtle destruction of the attacker's balance and rhythm and proper control of distance and timing are the primary focus of Bujinkan Taijutsu.  These principles allow even smaller persons to effectively defeat larger and more powerful opponents. The fighting skills of the Bujinkan Dojo were tested exhaustively in combat by the legendary ninja and samurai of Warring States Japan.

The International Bujinkan Dojo is directly supervised by Hatsumi Massaki Soke.  Presently, Hatsumi Sensei still lives and trains in Noda City, Japan.  He actively teaches every week at the Ayase Budokan in northern Tokyo and at the Bujinkan Honbu Dojo in Noda.
