Upcoming Riichi Mahjong Tournaments

What’s Happening Around the USA

Our friends at WRC have opened their testing windows. If you’re interested in WRPM & @worldriichimahjong check this out.

From coast to coast, this weekend our community was sharing mahjong in big ways! @pacificmahjongleague was on-site at Sakura Con, @riichi_noco hosted a huge beginners event, @lone_star_riichi taught sessions at Weebcon, and @philly_mahjawn even had the media at their clubhouse this weekend. Great job to everyone out there spreading the riichi love!

Day one of the @dcriichimahjong Open is in the books! Who are you rooting for on day two? Let us know in the comments!

Lots of great competitive events coming up with this next World Riichi League season in the US! Register now for the April events.

We love these pictures from a recent meetup of the Urbana Mahjong Pit’s Urbana-Champaign weekly meet!

The @kc_riichi club hosted a practice tournament this past weekend. These types of events are a great opportunity to support club members in their growth as competitive players!

Tulsa Asia Fest was a great success this year for the team at @ok.mahjong & they were able to share our favorite game with lots of new players. Congratulations to the team in Oklahoma!

This winning hand in all-last was submitted to us by the team at @queencityriichi from one of their recent meetups. Send us your fun hands! Congrats to Austin on this great hand!

@riichi_noco recently hosted a “new year, new hobby” event & 16 new people attended, giving them a packed venue & lots of community growth. We love the name of their event. Tell us about how your club is bringing in new players for 2026. We love hearing your creative ideas!
