Sumo Tournament

The Rain City Open sumo tournament returns in 2026 with a greater vision for the event, with more Japanese tradition, more excitement and a grander scale.

This year’s tournament will be held in the Seattle Center Exhibition Hall on Saturday, April 11, 2026. The main doors on Mercer St will open around 10:30AM, and the tournament will begin promptly at 11:00 with an opening ceremony and performance by the Ryushin Creative Dance Group from Okinawa. Some of the most exciting divisions will happen early in the day, so don’t sleep in!

In addition to the sumo, you’ll find food, t-shirts and gifts, taiko drumming, and even activities, such as the wildly popular tegata making, where you can make your own Sumo hand print autograph!

And best of all, ENTRY IS FREE for spectators!

Mark your calendars and we’ll see you there. Hakkeyoi!

The 2026 Rain City Open will be live streamed on Rain City Sumo’s YouTube channel for those who cannot make it in person.
