Ōza (shogi)
Ōza (王座 ) is one of the eight 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]
The tournament is sponsored by Nikkei, Inc. (日本経済新聞社 nihon keizai shinbunsha ), a newspaper conglomerate that publishes The Nikkei and the Nikkei 225 stock market index. The current Ōza title holder is Sōta Fujii .
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 reaching the age of 60 years, retirement or death.[ 3]

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.[ 6]
For the 31st Oza Match (1983), the tournament was officially elevated to major title match status and starting with the 32nd Oza Match, the format switched to a best-of-five.
