Ishigaya Kosaku

    Keywords: People

Ishigaya Kosaku (石谷広策, real name Koji 広二) (1818-1905/6) was a pupil of the Honinbo house and notable Honinbo Shusaku admirer. He published Kogyoku Yoin (1897), Shusaku Koketsu Kifu (1904), and erected a large memorial monument to Honinbo Shusaku. The monument pleased the house and Ishigaya was allowed to use a character from Shusaku's name, 策 (which is also shared by another great Honinbo, Dosaku). He acheived 5 dan in 1876.


In his books, Ishigaya gave glowing accounts of Honinbo Shusaku's character/strength and began using the term Kisei (棋聖, Go sage) when referring to him. This would influence later appraisal of Honinbo Shusaku, especially in combination with Segoe Kensaku's 10-volume castle games publication, Oshiro Gofu.
