Where it stands

As of 24 Aug 2026

As of 24 Aug 2026 the tournament is fixed and organizer-confirmed: 9 Jul 2028 to 23 Jul 2028 at IG Arena, Nagoya, general sale from 20 May 2028, banzuke on 26 Jun 2028.

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 Still unpublished: the free Ticket Oosumo advance lottery.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 7 May 2028 to 10 May 2028 with results about 12 May 2028, 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 2026 Nagoya basho ran the free round from 13 days before the Saturday general sale to 10 days before, with results 8 days before, and this record already used that shape, which the published ladder matched exactly. sumo.pia.jp/sumo07.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 5 Apr 2028. The paid Fan Club rounds run shortly before the free draw and are not scheduled yet either.

How to enter

Register free at sumo.pia.jp; apply online during the window; random draw; results ~18:00 JST via MyPage/email; automatic card charge between close and results.

Your odds

No official odds published; fully random draw; Nagoya editions at IG Arena have sold out completely, so expect heavy oversubscription.

Good to know

• The tournament itself is already official. The Japan Sumo Association publishes its English Grand Tournament Schedule three years ahead, so 9 Jul 2028 to 23 Jul 2028 at IG Arena, Nagoya, the general sale on 20 May 2028 and the banzuke on 26 Jun 2028 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 20 May 2028 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 26 Jun 2028, which is 37 days after the general sale opens on 20 May 2028, so you pick your day before the matchups exist.
