[edit] Outline

The Honinbo is the oldest Go title in the world, currently on its 61st edition. The sponsor is Mainichi Shimbun. The winner's purse is 32,000,000 Yen ($280,000).

The tournament is similar to the other two biggest Go titles in Japan, the Kisei and Meijin. The holder is challenged by whoever wins the round robin league. Players can get into the round robin league by going through many preliminary tournaments. Once there is a challenger to compete against the holder, the winner is decided through a best of seven match. The games are played over two days and each player is given 8 hours of thinking time. There are also more rewards than just money from the Honinbo tournament. Like the other biggest titles in Japan, if a player qualifies for the Honinbo league, they are automatically moved up to 7 dan. If that same player wins the league, a promotion to 8 dan is given. If that same player goes on to winning the title, they are finally promoted to 9 dan, the highest rank.
