M.LEAGUE x World Riichi U.S. Tour sets records and launches global alliance

The first multi-city professional mahjong tour in the U.S. drew sold-out crowds, about 40,000 livestream viewers a day, and a five-party alliance that opens Japanese leagues to World Riichi players. The tour also launched a new English-language publishing arm ahead of the 2028 World Riichi Championship in New York City.

Why it matters: - The tour pushed riichi mahjong deeper into the U.S. market with sold-out events, stronger English coverage and a live international audience. - The new five-party alliance gives World Riichi Professional Mahjong members access to tournaments and leagues run by major Japanese organizations. - The tour also expands the sport’s media footprint through new English strategy books and a larger global content pipeline.
