The Agon Cup (阿含桐山杯) is a Go competition.
The Agon Cup is a Go competition endorsed by the Nihon Kiin. It was started in 1994 by Agon Shu. The name was originally the "Acom Cup" but it changed its sponsor in 1999 and became the Agon 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 ($86,000).
