Yokozuna Kisenosato tasted his first defeat of the Autumn Grand Sumo Tournament on Friday, losing in an upset to No. 2 maegashira Chiyotairyu.

The other two yokozuna, Hakuho and Kakuryu, remained undefeated, while ozeki Takayasu also maintained a perfect record on the sixth day of the 15-day tournament at Ryogoku Kokugikan.

Seeking a quick result following a run of energy-sapping victories, Kisenosato charged his opponent from the jump in the final bout of the day.
