The Agon Kiriyama Cup (阿含･桐山杯) is a Japanese Go competition.
The Agon Kiriyama Cup is a Go competition endorsed by the Nihon Kiin. It was started in 1994[1] by Agon Shu. The name was originally the "Acom Cup" but it changed its sponsor in 1999 and became the Agon Kiriyama Cup. It is a single knockout tournament, but unlike the big titles in Japan, the title holder does not wait for a challenger, hence the difficulty of defending the title. The prize for the winner is 10,000,000 yen, a larger prize than some of the top-seven major titles.[2]
The tournament has a counterpart in China, the Ahan Tongshan Cup; the winners of the two tournaments face off in the China-Japan Agon Cup.
