September
At the Aki basho in Tokyo, Asashoryu's chance for a clean sweep of the 2004 tournaments is dashed when he pulls off a poor 9–6 record and
Kaio gets his 5th championship with a 13–2 record. Asashoryu's mediocre performance is attributed to a lack of training due to his wedding reception on 31 August.

Miyabiyama on Day 12 can only manage a runner-up score of 12–3 in his hometown tournament, just one win short.
