The Kansai Ki-in is one of the professional go bodies in Japan, just like the Nihon Ki-in. Shortly after the Second World War the Nihon Ki-in set up a Western Japan branch. The main driver for this was the increasing difficulty professionals from the Osaka region experienced during the war traveling to Tokyo for their professional activities. When a dispute over the Honinbo title arose between the Tokyo and Osaka branches, the latter declared itself independent in September 1950 and the Kansai Ki-in was born. The founder was Hashimoto Utaro.
