Ōi (王位?) is one of the seven titles in Japanese professional shogi. The word means "the king's rank" (ō(王) = king, i() = rank or position).

The annual tournament started in 1960 sponsored by a group of local newspapers which has consisted of Shimbun Sansha Rengō (Three-Newspaper Association).[1] Despite of its name, Shimbun Sansha Rengō is currently formed by six newspapers: Hokkaido Shimbun, Tokyo Shimbun, Chunichi Shimbun, Kobe Shimbun, Tokushima Shimbun and Nishinippon Shimbun.[2]

The challenger for the title is determined by three-step preliminary round that comprises 1st heat, league competition and final playoff. Top eight players in 1st heat and top four players of previous year are divided into two six-player leagues. Top one of each league advances to final playoff, and the winner of one-game match becomes the challenger.

The player that wins four games out of seven first in the championship will become the new Ōi title holder. Each championship games assign players a six-hour playtime during two days.[3]

Lifetime Ōi[edit]

Lifetime Ōi ("Eisei-Oi" = Lifetime Ōi) 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.
