If you mention Minori Hirai you should also mention he founded his own Aikido M.A.: "Korindo Aikido". Unlike most of the Aikido styles you mentioned so far, Korindo Aikido not only does not consider itself to be a branch of Ueshiba's teaching, it is also not based on daito ryu, rather on other Koryu styles Minori Hirai studied.Caine said:Here is an excerpt from an interview with Minori Hirai who was partly responsible for the name change:
I believe you played major role in the name-change from Aiki Budo to Aikido when you were a representative of the Kobukan Dojo to the Daà Nihon Butokukai (see side bar).
I was the Director of General Affairs of the Kobukan beginning around 1942 and I helped out Ueshiba Sensei in dayly matters. "Aikido", rather than being a specifically selected name, was the term used to refer to "Butokukai-Ryu", aiki budo within the Daà Nippon Butokukai. The headquarters of the Daà Nippon Butokukai was located in Kyoto and Butokuden centers were set up in all prefectures. Tatsuo Hisatomi from the Kodokan, and Shohei Fujinuma from Kendo, were close friends of mine. The Butokukai was an independent, umbrella organization for the martial arts, and it also was in charge of martial arts in the police departments.
