Former sekiwake Kotonishiki of the Sadogatake stable decided to hang up his mawashi on Sunday after struggling with a 1-6 record in the second-tier Juryo Division at the Autumn sumo tournament.
Kotonishiki, the only wrestler to win the Emperor's Cup twice as a maegashira wrestler, informed stablemaster Sadogatake of his decision Saturday evening.
The former sekiwake, who was wrestling as the top-ranked wrestler in the juryo division, told Sadogatake that he had reached his physical limits and it was time to retire from sumo.
