Welcome to the 2018 North American Open

October 13-14, 2018

New York, NY

We are proud to announce a landmark Riichi tournament here in North America - the first North American Open. This tournament will stand alongside other major tournaments such as the European Riichi Mahjong Championship (ERMC) and the World Riichi Championship (WRC) as a major, regularly run, worldwide Riichi event. Join us in starting a new tradition by participating in the inaugural event this year in the heart of New York City.

The North American Open is a NARMA event, hosted in 2018 by USPML.


The Down Town Association remains an island of quiet civility in a bustling Lower Manhattan. As a locus for nourishment, entertainment, relaxation or quiet discourse, the Club has remained of and for its members since its inception in 1859.
