The Honinbo is the oldest professional Go tournament in the world. Today it is, arguably, still the most prestigious title in Japan.
The Honinbo tournament is sponsored by Mainichi Shimbun (The Daily Newspaper) and the prize money is currently $32 million Yen.
During the Edo period, the Honinbo was a 'hereditary' title, which was bestowed upon the head of the Honinbo school, passed down from master to student. The last hereditary title holder, Honinbo Shusai, sold (some say gave) the title to the fledgling Nihon Kiin (Japanese Go Association) and it became a tournament title.
Typical of Japanese titles, the title holder is challenged by the winner of a league. The title is decided in a best of seven match. Each player is given eight hours of play over a two day period.
