Yokozuna Hakuho survived a scare against new komusubi Abi on Sunday to open the Nagoya Grand Sumo Tournament with a win and start off strong in his campaign for a record-extending 43rd championship.

On the first day of action at Dolphins Arena, Hakuho was taken by surprise following a spirited offensive from Abi and looked momentarily in danger of an opening-day upset.

But the Mongolian yokozuna, who sat out the last tournament to nurse a right arm injury, adjusted fast to spin Abi around and down, exacting revenge for a loss to the komusubi last year in May, the only other time the wrestlers had fought.
