NAGOYA (Kyodo) -- New yokozuna Onosato brushed aside rank-and-file opponent Kinbozan to tie for first place at the Nagoya Grand Sumo Tournament on Saturday after sole overnight leader Mitakeumi's unbeaten run came to an end.

Onosato, the only competing grand champion following Hoshoryu's injury withdrawal, advanced to 6-1 after exploding out of the blocks and pushing No. 3 maegashira Kinbozan (1-6) straight off the dohyo in the final bout of Day 7 at IG Arena.

The 25-year-old yokozuna shares the top of the leaderboard with former ozeki Mitakeumi, sekiwake Kirishima, plus rank-and-file wrestlers Tamawashi, Ichiyamamoto and top-division debutant Kusano, competing as a No. 14 maegashira.

Three-time Emperor's Cup winner Mitakeumi, fighting near the bottom of the rankings as a No. 16 maegashira, saw his bid for a perfect opening week thwarted by another newcomer to the elite makuuchi division, No. 14 maegashira Fujinokawa (5-2).

Kirishima made quick work of Takayasu (5-2) in a battle of former ozeki, slapping the 35-year-old komusubi to the clay.

Ozeki Kotozakura finished the first week of the 15-day tournament one win off the pace at 5-2 after forcing out up-and-coming No. 4 maegashira Hakuoho (3-4).

Exciting young Ukrainian No. 1 maegashira Aonishiki (5-2) also moved to the second rung by pushing out new komusubi Oshoma (1-6) and adding another name to his growing list of higher-ranking victims.

Veteran No. 4 maegashira Tamawashi sprang an upset by thrusting out sekiwake Wakatakakage (3-4), while No. 8 maegashira Ichiyamamoto continued his bid for a maiden Emperor's Cup by slapping down No. 6 maegashira Takerufuji (4-3).
