Background

The annual tournament started in 1960 sponsored by a group of local newspapers which has consisted of Shimbun Sansha Rengō (Three-Newspaper Association).[1][lower-alpha 1] 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.[1]
