Yokozuna Kakuryu suffered his first defeat after an upset loss to Ikioi on Wednesday, the fourth day of the Nagoya Grand Sumo Tournament.
Kakuryu (3-1) was immediately pushed onto the back foot by the No. 2 maegashira and was unable to recover against a relentless charge from Ikioi (1-3) that forced the yokozuna over the straw.
"I really concentrated and was able to get the win. I didn't really have a plan, I just wanted to go all out in the ring. I'll keep giving it my all for the rest of the tournament," said Ikioi, who picked up his fifth kinboshi prize for the win.
