is one of the eight major titles in professional shogi, and it means "the king's rank" (王 ''ō'' 'king' + 位 ''i'' 'rank, position').


Background

The annual tournament started in 1960, sponsored by a group of local newspapers which has consisted of Shimbun Sansha Rengō (Three-Newspaper Association). With the addition of Ōi, there were four major shogi titles along with Meijin, Ninth Dan ( Ryūō), and Ōshō.


Format

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.
