Ōi (王位) 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
[edit]The annual tournament started in 1960, sponsored by a group of local newspapers which has consisted of Shimbun Sansha Rengō (Three-Newspaper Association).[1][a] With the addition of Ōi, there were four major shogi titles along with Meijin, Ninth Dan (Ryūō), and Ōshō.
Format
[edit]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]

Lifetime Ōi (永世王位, eisei Ōi) is the title awarded 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.[2]
Only three professionals have qualified for the Lifetime Oi.[2] They are as follows:

- Makoto Nakahara (retired)[4]
- Yoshiharu Habu (active)[5]

- ^ Game three ended in impasse after 178 moves and was officially recorded as a draw. This was the first drawn championship-round game in the history of the tournament.
