Yokozuna Kakuryu survived a scare Thursday to remain undefeated on the fifth day of the 15-day Spring Grand Sumo Tournament.

Pushed to the edge of the straw bales by No. 2 Takarafuji, the sole yokozuna at Edion Arena Osaka failed to keep both feet inside while pulling down his charging opponent.

Unable to determine whether Kakuryu's foot left the ring before Takarafuji's shoulder hit the ground, the judges ordered a rematch.
