Kanoukan is a Japanese kobudo organisation with its headquarters in the Hiroshima prefecture. Kobudo and koryu refer to old Japanese battlefield martial arts from the time of the samurai, before the meiji restoration in 1867.
The founder and chief instructor, master Kunio Morimoto is a well-known figure in Japanese budo. He is a director of the Nihon Kobudo Shinkokai and a full member of the Nihon Kobudo Kyokai, Japan's two oldest and most prestigious governing bodies for ancient martial arts.
Because of the nature of the battlefield, samurai warriors had a wide range of skills and did not just specialise in one area of combat. For this reason, most koryu arts have many weapon techniques in addition to unarmed waza (techniques). Kanoukan teaches 3 koryu styles and within these systems are both armed and unarmed waza.
The koryu styles are;
Shibukawa Ichi Ryu Jujutsu,
Muso Shinden Eishin Ryu Iai Heiho
Oishi Shinkage Ryu Kenjutsu.
In London, England Shihandai Jacob Greasley of Jikan Budokai International has been authorised to teach and promote these arts on behalf of Kanoukan.
