The Nihon Kiin had a Kansai branch even before the Second World War. In 1947, it became a separate corporation, Kansai Kiin, still under the Nihon Ki-in. In particular, the Kansai Kiin could not issue diplomas on its own. When a dispute over the Honinbo title  arose between the Tokyo and Osaka branches, the latter declared itself independent in September 1950. Hashimoto Utaro, Honinbo titleholder at the time, played a crucial role in going independence. However, those who opposed the independence set up Nihon Kiin Kansai Branch anew and this divided state weakened the Kansai (the West) players as a whole.
:The Nihon Kiin announced that the Honinbo title term would be shortened from two years to one year without consulting the reigning Honinbo, Hashimoto.
