Yokozuna Hakuho increased his record total of grand sumo tournament championships to 37 on Saturday, when he won the 15-day Summer Grand Sumo Tournament with a day to spare.

A day after dodging a bullet to see off previously unbeaten ozeki Kisenosato, the Mongolian master beat compatriot and fellow yokozuna Harumafuji (10-4) to improve to 14-0. Kisenosato followed Hakuho to the raised ring for the day's final bout, but was easily forced out to his second straight loss.

"I just focused on my bout," Hakuho said. "It's been a while since I clinched it in this manner. I'm genuinely glad to win here in Ryogoku (Kokugikan) in Tokyo for the first time in a year and a half."
