The home of professional riichi in America
USPML is the U.S. arm of World Riichi Professional Mahjong — the only internationally recognized professional riichi program. We hosted the World Riichi Championship in 2017. In 2028 we bring it to New York.
Backed by the world of professional riichi
USPML operates the World Riichi League in the United States, in partnership with the World Riichi Championship, and is the only American organization that holds reciprocal agreements with all four of Japan’s major professional organizations.
