Okuyama’s first Dojo was located in Asahikawa and was called Nippon Shidokai Ryubukan, in 1939 he moved to Kanda and opened another dojo called Dai Nihon Shidokai, this marked the beginning of the split from Daito Ryu, by this time Takeda was very old and his son Tokimune was still very young, seeing no place for advancement in the Daito Ryu school, and being a skilled medical and martial person, Okuyama began to form his own system based on Daito Ryu Jujutsu and Daito Ryu Aiki no jutsu.”
