Background & story
The Natsu Basho (Summer Tournament) is the May installment of professional sumo's six annual honbasho. Three of those six are held in Tokyo at Ryogoku Kokugikan — in January, May, and September — making the Summer Tournament a prime chance for visitors to see the sport in the capital as spring turns to early summer. Each honbasho spans 15 days from a Sunday to a Sunday, with a wrestler's daily result building toward the makuuchi championship decided on the final day (senshuraku).
Good to know
Buy through the official English ticket site (sumo.or.jp/EnTicket), which accepts international cards; advance sale typically opens about 5–8 weeks before the tournament and Tokyo weekends and final days sell out fast — check the site for the exact 2027 on-sale date. A limited number of same-day chair seats (tojitsu-ken) go on sale at the box office each morning, first-come. For the full day-by-day schedule and seat-type breakdown, see our Grand Sumo schedule guide, and for a step-by-step booking walkthrough see our Grand Sumo tickets guide. Etiquette note: keep your seat cushion on your seat — throwing zabuton after an upset is prohibited for safety (as of July 2026).
