The '''Nihon Ki-in''' ({{Lang|ja|日本棋院}}), also known as the '''Japan Go Association''', is the main organizational body for [[Go (board game)|Go]] in [[Japan]], overseeing Japan's [[go professional|professional system]] and issuing diplomas for amateur [[dan rank]]ings. It is based in Tokyo. The other major Go association in Japan is [[Kansai Ki-in]]. 
Its innovations include the [[Oteai]] system of promotion, time limits in professional games, and the introduction of issuing diplomas to strong amateur players, to affirm their ranks.

==History==
The Nihon Ki-in was established in July 1924.<ref>{{cite book|last1=Power|first1=John|title=The Go Player's Almanac|date=1992|publisher=Ishi Press|isbn=4-87187-040-5|page=48/1}}</ref> 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 house|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]].<ref>{{cite book|last1=Power|first1=John|title=The Go Player's Almanac|date=1992|publisher=Ishi Press|isbn=4-87187-040-5|page=63/1}}</ref>

==Tournaments==
The Nihon Ki-in organizes many tournaments for professional players. The major title tournaments include the [[Kisei (go)|Kisei]], [[Meijin (go)|Meijin]], [[Honinbo (competition)|Honinbo]], [[Judan (Go)|Judan]], [[Tengen (Go)|Tengen]], [[Gosei (competition)|Gosei]], and the [[Oza (go)|Oza]].<ref>{{Cite web |title=Japanese Go Tournaments |url=https://gobase.org/games/jp/ |access-date=2022-11-24 |website=GoBase.org}}</ref> There are also separate Honinbo, Meijin, and Kisei titles for women.
