NAGOYA - Yokozuna promotion-chasing ozeki Kirishima joined six other wrestlers at the top of the Nagoya Grand Sumo Tournament leaderboard on Saturday after rank-and-filer Shishi suffered his first defeat after seven days of action.

Kirishima (6-1) had to fight his way back from a patchy start against last year's Nagoya meet winner, sekiwake Kotoshoho (3-4), with the ozeki finding himself on the back foot before coming to a standstill in the middle of the raised ring at Nagoya's IG Arena.
