Yukiyoshi Sagawa (佐川幸義) was one of the senior students of Sokaku Takeda, Morihei Ueshiba O-Sensei’s instructor in Daito-ryu, and was actually designated as the successor to Takeda at one point in time. He began studying Daito-ryu under Takeda Sokaku after first learning the art from his father, Nenokichi Sagawa (佐川子之吉 1867–1950), who was a student and ardent supporter of Takeda, as well as a holder of a Kyoju Dairi (assistant instructor’s licence) in Daito-ryu – the same license that Morihei Ueshiba himself received from Sokaku Takeda. Yukiyoshi Sagawa received his own Kyoju Dairi certification in 1932.
Takahashi Sensei instructs at the Sagawa-den Daito-ryu Aiki Budo Sagamihara branch dojo (佐川伝大東流合氣武道相模原支部), at the Daito-ryu Sagawa Dojo hombu (大東流佐川道場本部) in Kodaira city, and has published a number of books and articles researching the Japanese martial arts and Daito-ryu. This article is an excerpt from his book "The Truth of Daito-ryu Aiki" (大東流合気の真実), which was published in Japanese by Fukushodo Co. Ltd.(http://fukushodo.com/) in September 2007.Another excerpt from this book appears in "Sagawa Yukiyoshi, Masaru Takahashi and Breath Training in Daito-ryu".
