Hakuho wrapped up his seventh career championship win in style after overpowering Bulgarian Kotooshu to finish the Nagoya Grand Sumo Tournament on July 27 with a spotless record.

Hakuho, who clinched the Emperor's Cup after beating Kaio on July 25, faced a stern test in the day's finale but closed out the championship with a 15-0 mark for only the second time in his career.

Kotooshu gave as good as he got but Hakuho eventually got the upper hand. After working Kotooshu to the edge, he tipped the ozeki over the straw edge of the ring with a textbook overarm throw.

"The Nagoya tourney title is the only one I hadn't won so I'm absolutely delighted," said Hakuho, who won all of his bouts for the first time as a yokozuna.
