M.League 「Mリーグ」 is a professional mahjong team league. It is the first league in which mahjong players receive a salary for playing games. Players are drawn from the various mahjong professional leagues. An M.League season consists of a number of regular season games, followed by a playoff final. Each team is sponsored by a company and represents their respective company. All league activities take place in the M.League Studio.

Format

The main format of the competition is made up of a regular season and a post-season. The basic format of the season varies in the number of hanchan played.

Current format

With nine teams, the regular season takes 108 days for 216 hanchan. This grants 96 hanchan per team. After the final day of the regular season, the top six teams advance to the semifinals, where they play 30 hanchan on a 15-day schedule (20 hanchan per team). In the finals, the top four teams play another round of 16 hanchan on an 8-day schedule.

Rules and regulations

The game rules are given in the Official M.League Rules 「Mリーグの公式戦ルール」. All games are played in the form of hanchan using AMOS brand professional mahjong tables.

Game day

Each game day session consists of two hanchan. Teams scheduled to play send one team member for each of the two hanchan. If desired, one player may play both hanchan.

Game rules

The league rules follow the general riichi mahjong rules with special competition settings. The starting score is 25,000 points; the target score is 30,000 points; the uma is +30/+10/-10/-30.^[1]

Draft

Before the start of each season, a day is set for team drafts. Teams select from a field of players from the various professional organizations. The inaugural draft was held on August 7, 2018. Naturally, each team made their player selections to fill out their roster in the inaugural draft. For subsequent drafts in later years, teams had the option of drafting new players or otherwise passing on the opportunity. Beginning with the 2022–23 season, passing is no longer allowed. Currently, each team has a roster of four players.
