Oza (shogi)

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 and was a non-title tournament up until 1982. 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. [1]

Lifetime Ōza

"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.[2]

Winners

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.[5]
