Mongolian yokozuna Hakuho put on another sumo clinic to beat Georgian komusubi Tochinoshin on Friday and preserve his unbeaten record six days into the New Year Grand Sumo Tournament.

Hakuho, seeking a record-extending 36th career title, was never in danger in the third-from last bout at Ryogoku Kokugikan, getting a firm left-handed grip on Tochinoshin's (2-4) belt and sending him sprawling to the sandy surface with an overarm throw.

There was no change at the top of the leaderboard heading toward the end of the first week at the 15-day basho as ozeki Kotoshogiku and No. 8 maegashira Takayasu also won handsomely to keep their share of the lead at 6-0.
