The story

The Nihon Ki-in was established in July 1924. The first president of the Nihon Ki-in was Makino Nobuaki, a great Go patron himself, with Okura Kishichiro serving as vice president. The vast majority of pros at the time joined the fledgling organization, excepting the Inoue faction in Osaka and Nozawa Chikucho. A brief splinter group called Kiseisha was created soon after the Nihon Ki-in was formed, but most of the players involved had returned to the Nihon Ki-in within a couple of years. Then in 1950, its western branch split away to form the Kansai Ki-in.
