Upcoming Riichi Mahjong Tournaments

What’s Happening Around the USA

We are now accepting proposals for hosting the 2028 invitational. We’d love to hear from your club! Visit our website for more details!

Congrats to the mahjong club at the University of Wisconsin on another Spring Tourney! In true Wisconsin fashion, they hand out cheese as prizes! We love seeing growth in college clubs!

Congrats to @queencityriichi on their best ever gathering of six tables today! Check out this awesome club in Ohio if you’re in the area!

@pacificmahjongleague held their annual invitational this past weekend and the competition was fierce! Congrats to all who played & to the champion, Airi!

Congrats to @kc_riichi on a great weekend of teaching mahjong at the Midwest Gamefest!

The crew at @nycriichinomi spent their weekend at the Castle Point Anime convention, sharing the love of mahjong! Conventions are a great way to connect with a new crowd of players!

Spring weather has some clubs ready to get outside and play, while others stay inside while they experience the last bits of cold weather. Our friends in @indianapolisriichimahjong chose a bit of outdoor play this past weekend, while our friends at @marmriichi chose to keep their 3 tables of fun inside. Are you ready for outdoor play?

Good luck to all playing in the Rochester Riichi Open this weekend!

Congratulations to the top 4, including winner Ron, from the DC Open! What an awesome event that keeps growing every year! Great job, @dcriichimahjong
