M.League 「Mリーグ」 is a professional mahjong league founded in 2018. It is a team competition: teams draft players from various mahjong organizations, then compete over a season to reach the top. It is the first league that pays a salary to its mahjong players; each team is sponsored by a company.

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

There are nine teams, with four players per team. The regular season lasts 108 days for 216 hanchan (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

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. Each team that is scheduled to play will send one team member per hanchan. If desired, one player may play both hanchan.

Game rules

The 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 bonus of oka and uma is +50/+10/-10/-30. [1]

Notable rule variations

Penalty

M.League has four types of penalties: chombo, dead hand, yellow card and red card.

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. During the inaugural draft (2018), each team made their player selections. For each year thereafter, 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.

Announcers

Guest

Several guest commentators appear on the program. The most regular guest commentator is Koushou Tsuchida. Other commentators may be either current league players, former members, or other mahjong professionals.

M.League Studio

The league has its own studio for games and broadcasts, located in Hamamatsuchou, Minato, Tokyo. All games during a season take place in the M.League studio.

A jansou called M.League Stadium is open to the public in Takadanobaba.

Teams

As of the 2023–24 season, there are nine teams competing in the league. Each team must have four players drafted from five professional mahjong organizations: Saikouisen Nihon Pro Mahjong, the Japan Professional Mahjong League (JPML), Nihon Pro Mahjong Kyoukai (NPM), Mahjong Union (MU), and Real Mahjong Unit (RMU).
