Kanki Izumigawa (泉川 寛喜, Izumigawa Kanki, 1908 – 1967) was a karate master who learned Goju-Ryu from Seiko Higa on Okinawa and Saipan. Higa had studied under Kanryo Higashionna (of Naha-Te) and trained with Chojun Miyagi (the founder of Goju-Ryu). In his youth Izumigawa also studied karate under Juhatsu Kyoda, who was himself a senior student of Kanryo Higashionna. Izumigawa was born in Okinawa to a samurai family and was the founder of the Senbukan Dojo, which had its headquarters in Kawasaki City and branches in Tokyo, Osaka, Ota, Yokoyama, Nagoya and even Hawaii. The Senbukan dojo was established in 1939 and was the first dojo of Okinawan Goju-Ryu on mainland Japan. Today, It's currently the oldest Goju-Ryu dojo in the world.
