In the day's final bout at Ryogoku Kokugikan, Mongolian Asashoryu got a left-hand grip of Miyabiyama's belt and waltzed the sekiwake grappler out to improve to 8-1. Miyabiyama fell to 2-7 in the 15-day tourney.

The vaunted Asashoryu, who is gunning for his 20th Emperor's Cup, is one win ahead of four other wrestlers.

Mongolian Hakuho improved to 6-3 when fellow ozeki Tochiazuma slipped on the sand and fell to 4-5.

Ozeki Chiyotaikai stayed in the hunt for the Emperor's Cup when he shoved Kaio back at the faceoff and then swatted his opponent down to improve to 7-2.

Ozeki Kaio put up little resistance and dropped to 5-4.

Bulgarian ozeki Kotooshu was having none of the pre-bout antics of fifth-ranked maegashira Takamisakari and deployed a frontal push out to give both wrestlers a record of 6-3.

Takamisakari gets the crowd riled up with a routine that includes beating his chest and slapping himself in the face.

In earlier bouts, rank-and-filers Tamanoshima and Tamakasuga both lost to fall out of the lead.

Ninth-ranked maegashira Toyonoshima shoved out No. 11 Tamakasuga to give both wrestlers 7-2 records while No. 13 Yoshikaze (5-4) upset fourteenth-ranked Tamanoshima, who fell to 7-2.
