Ōza (王座) is one of the eight titles in Japanese professional shogi.
The word literally means "king's seat", i.e., "throne".
The player that wins three games out of five in the championship match becomes the new Ōza title holder.
The current Ōza title holder is Sōta Fujii.
Active players may qualify for this title, but it is only officially awarded upon their reaching the age of 60 years, retirement or death.
