The Meijin tournament is a Japanese professional go competition featuring a challenge against the Meijin for his title.
C and B Preliminaries
Players from the Kansai Ki-in and the Chuubu branch of the Nihon Ki-in compete in a separate set of single-knockout preliminaries, advancing from C to B. The top 10 players qualify for the A preliminary.
The last preliminary is a single-knockout tournament comprised of 30 players, including:
- The 13 players who qualified in the A preliminary held by the Nihon Ki-in for players of its Tokyo main branch.
- The 5 players who qualified in the A preliminary held jointly by the Kansai Ki-in for its players and the Nihon Ki-in for the players of its Chuubu branch.
- The 3 players who were bottom-most ranked in last year's league and lost their places in the league.
The 3 qualifying players progress to the league.
The league is comprised of 9 players:
- The top 6 players from last year's league
- The 3 qualifying players from the last preliminary
The league plays a round-robin tournament, and players are ranked based on performance.
- The bottom 3 players lose their positions in the league and are returned to the last preliminary
- The top player progresses to the title challenge
In the event that two players tie for top performance in the league, the two tied players advance to a playoff.
In the event that players are tied for the top position in the league, the tied players will advance to a playoff to determine who earns the right to challenge the Meijin. The winner advances to the title challenge.
The winner of the league (or playoff, if necessary) challenges the Meijin for his title in a best-of-7 series. The winner of the series gains (or retains) the title of Meijin, and will await next year's challenger.
"Meijin" may be assumed as an honourary title by players who have won the title 10 times in a row, or at the age of 60 or at retirement by players who have mounted 5 successful sequential defences of the title.
It takes 27 months to progress from Preliminary C to the final title match.
