Oza (shogi)

Jump to: navigation, search

Ōza (王座?) is one of the seven titles in Japanese professional shogi. The word literally means "king's seat", i.e., "throne". The tournament started in 1953 as a knockout tournament with three games in the final match and was a non-title tournament up until 1982.[1] The challenger for the title is determined through three preliminary rounds. The player that wins three games out of five in the championship match becomes the new Ōza title holder. [2]

Lifetime Ōza[edit]

"Lifetime Ōza" (名誉王座?) is the title given to a player who won the championship five times in a row or ten times in total. Active players may qualify for this title, but it is only officially awarded upon their retirement or death.[3]

Winners[edit]

From 1953 until 1982, the tournament was just regular tournament and not a major title match. From 1953 to 1969, two finalists would play a 3-game match to determine the overall winner; the 1st Oza match (1953), however, was only a single game. From 1970 to 1982, the winner of the previous year's tournament would play the winner of a qualifying tournament in a 3-game match.[6]
