Where it stands

As of 24 Aug 2026

As of 24 Aug 2026 the tournament is fixed and organizer-confirmed: 12 Sept 2027 to 26 Sept 2027 at Ryogoku Kokugikan, general sale from 7 Aug 2027, banzuke on 30 Aug 2027.

All four come from the Nihon Sumo Kyokai's own English Grand Tournament Schedule, which publishes three years ahead. Still unpublished: the free Ticket Oosumo advance lottery.

This record projects it at 29 Jul 2027 to 1 Aug 2027 with results about 3 Aug 2027, so treat those three dates as estimates. The projection is no longer a guess from the sale date alone: it now follows the free round's actual published shape in the 2026 cycle.

The Kokugikan basho of the 2026 cycle (January, May and September) all ran the free round from 9 days before the Saturday general sale to 6 days before, with results 4 days before, so this record uses that shape. sumo.pia.jp/sumo09.jsp publishes the real ladder once the paid Fan Club rounds are scheduled, which in the 2026 cycle was 3 to 5 weeks before the general sale, so check it from about 23 Jun 2027. The paid Fan Club rounds run shortly before the free draw and are not scheduled yet either.

Good to know

• The tournament itself is already official. The Japan Sumo Association publishes its English Grand Tournament Schedule three years ahead, so 12 Sept 2027 to 26 Sept 2027 at Ryogoku Kokugikan, the general sale on 7 Aug 2027 and the banzuke on 30 Aug 2027 are organizer-published dates, not projections. The advance-lottery window is the only estimate on this page.
• The free Ticket Oosumo draw is an earlier rung than the general sale, not an alternative to it. Entering costs nothing and the draw is random, so the 7 Aug 2027 general sale is the fallback if the draw does not come through, and the lottery window is the part still to be announced.
• Tickets go on sale before anyone knows the card. The banzuke that decides who fights is published on 30 Aug 2027, which is 23 days after the general sale opens on 7 Aug 2027, so you pick your day before the matchups exist.
