Ōza (王座; "throne") is the second oldest of the seven big titles in Japanese professional Go.[1] The tournament is organised by the Japanese Nihon Ki-in and sponsored by the Nihon Keizai Shinbun, also known as The Nikkei. The six other big Go titles include the Kisei, Meijin, Honinbo, Judan, Tengen, and the Gosei.[2]

Outline
editThe Ozā has a similar format to other big Go tournaments in Japan. Since the 16th Ozā in 1968, the winner of a preliminary tournament, played in single knockout, advances to play a best-of-five match against the previous year's title holder. Previously, the tournament format was a best-of-three match between two final players from the knockout rounds.[4]
