Kakuryu took his frustrations out on Kotoshogiku, sending his sekiwake rival to his first defeat on the eighth day of the Autumn Grand Sumo Tournament on Sunday.
Mongolian Kakuryu got his left hand inside for a tight grasp on Kotoshogiku's mawashi before grinding his opponent over the edge in a matter of seconds to improve to an even 4-4 slate at Ryogoku Kokugikan.
Yokozuna Hakuho, meanwhile, bulldozed Tochiozan (6-2) in a lopsided affair to stay undefeated with an 8-0 mark in a two-way tie for the lead with sekiwake Kisenosato.
