# Meijin (renju)

Meijin (名人) is a Renju title in Japan. The Meijin title tournament, formally called the All Japan Renju Meijin-sen (全日本連珠名人戦), is played every year in Japan since 1962. The Meijin-sen tournament is one of the most important Renju tournaments in Japan.

## History and Rule

The first Meijin-sen tournament is organized by the Japanese Renju Federation in 1962. Since then, the tournament is played every year except for 1974. During every year with the Meijin title match, two rounds of qualification tournaments are held in parallel in different regions of Japan. The A-class league is made up of 10 players, which are composed of winners of different qualification tournaments, together with three seeds from the last tournament. A round-robin tournament is held among the A-class league, and the winner of the A-class league becomes the challenger of that year. Then a 5-round match is held between the challenger and current title holder. If the challenger gets at least 3 points from 5 games, he wins the match and gains the Meijin title. Otherwise, the current holder keeps the title.
