Karigane Jun'ichi (雁金 準一, July 30, 1879 – February 21, 1959) was a Japanese professional Go player, posthumously made an honorary 9 dan by the Nihon Ki-in.
In 1922, he formed the Hiseikai, a group tournament, which also included Chiyotaro Onoda, Segoe Kensaku, Tamejiro Suzuki and Dohei Takabe.
[2] Rivalry would persist between the two groups until 1991, when the Keiinsha, the eventual offshoot of the Kiseisha, was finally dissolved with the death of its last member.
During the first quarter of the twentieth century, Karigane was one of the two strongest Japanese players, and his major opponent was Honinbo Shusai of the Nihon Ki-in.
The two rivals, each backed by distinct organisations, finally agreed to play one another in what would become a famous and much anthologised game, lasting sixteen hours.
