He started practicing judo at the age of 17 in order to fortify his body. In 1939 he was introduced to Morihei Ueshiba and entered the Kobukan dojo.
He became one of the most important and influential aikido teachers during the 1950s to 1970s, being the director of the Aikikai Hombu Dojo for many years until 1986 when he was replaced by Morihei's grandson and present Doshu, Moriteru Ueshiba. He held the rank of 9th dan Aikikai.
His son, Hayato Osawa (b. 1951) also became a prominent aikido shihan holding the rank of 7th dan.Kisaburo Osawa - Wikipedia, the free encyclopedia
