January 5 is "囲碁の日", means "Day of IGO game".
January 15 is designated as the "いい碁の日 (Good day for GO game)".
There is a Koma-fuda (wooden signboard) with 囲碁「本因坊」発祥の地 (birthplace of IGO (GO) "Hon-inbo") at Ebisugawa, Teramachi-dori in Kyoto City.
It tells the origin of it and there is a stone GO board under the wooden board.
"Hon-inbo"is known as one of the titles of IGO.
In the Azuchi-Momoyama period, a temple called "Jakko-ji Temple" stood on this site.
The 2nd chief priest of Jakko-ji Temple, Nikkai who lived in the sub-temple of Hon-inbo, was a master of IGO.
It is said he taught IGO to Nobunaga ODA and Hideyoshi TOYOTOMI Ieyasu TOKUGAWA.
It is said that Nobunaga gave him the title of "MASTER" and Hideyoshi gave him the title of "碁 (GO)".
In the Edo period, Ieyasu called Nikkaijin to Edo and appointed them to "Godokoro (place)" of the bakufu.
Nikkai changed his name to Hon-inbo Sansa and became the founder of Godo Hon-inbo.
Later, Iemoto system was abolished and Honboin, a sub-temple of Jakko-ji Temple, also disappeared.
The name of Hon-inbo has been passed down to the present through the Igo "Battle of Hon-inbo" game, which inherits the name of Hon-inbo.
When the wooden board and the GO board were set up in 2009, the Uchihajime-Shiki (beginning ceremony) which consisted of nine steps of Imamura and nine steps of Takiguchi was held.
Even now, if you bring Go on this Go board, anyone can actually play Go.
Speaking of Goban (go boards grid), The streets of center area of Kyoto is said "Goban No Me (grid)" .
It may be a scene unique to Kyoto that you can play GO games on the grid in the Goban No Me (grid).
Jakko-ji Temple is called "Igo Hon-inbo Temple".
It was relocated 2 times before being restored in 1708 at its current location, Higashiyama Niomon.
There is a graveyard of the past Hon-inbo, and the GO-board and GO-stone used by Hon-inbo Sansa are preserved as temple treasure.
