He spent his entire life in pursuit of perfection through Budo, a pursuit which took him across Japan and China to test and further his knowledge. By the time he died in 1972 he was headmaster of many Ryu-ha (“family traditions”) of martial arts, granted to him by his grandfather and teacher Toda Shinryuken Masamitsu, as well as Mizuta Yoshitaro Tadafusa and Ishitani Matsutaro Takekage.
