Yukiyoshi Sagawa was a contemporary of Aikido Founder Morihei Ueshiba and a fellow student under Daito-ryu Chuku-no-so Sokaku Takeda. He often accompanied Takeda Sensei in his travels around Japan, and received his Kyoju Dairi (assistant instructor’s license) from Sokaku Takeda in 1932 (this is the same license that Morihei Ueshiba received from Sokaku Takeda in 1922).
In Sagawa Dojo the techniques that Sagawa Sensei learned from Sokaku Takeda were organized into ten levels (“Gen” / 元). Only a few of Yukiyoshi Sagawa’s students received the Kyoju Dairi certification from Sagawa Sensei, and among those only three have completed the 10th Gen.
One of the three student to have completed 10th Gen with direct instruction from Yukiyoshi Sagawa is Tatsuo Kimura (木村達雄), a long time student of Sagawa Sensei. Born in Tokyo Japan in 1947, Kimura Sensei is a well known mathematician and professor at Tsukuba University. He published two books about Sagawa Sohan (宗範) that have been translated into English (the latter one only partially) – “Transparent Power (透明な力)” and “Discovering Aiki My 20 Years with Yukiyoshi Sagawa Sensei (合気修得への道―佐川幸義先生に就いた二十年)”. He also holds a third-dan in kendo and a fifth-dan in Aikido, which he studied under Seigo Yamaguchi (山口清吾).
