Yokozuna Hakuho survived a scare against rank-and-file opponent Hokutofuji to remain perfect at the New Year Grand Sumo Tournament at Ryogoku Kokugikan on Wednesday.

With headlines on the fourth day of the 15-day tournament dominated by the retirement of Japanese yokozuna Kisenosato, the other remaining yokozuna, Mongolian Kakuryu, was also victorious.

Hakuho, looking to extend his record win total to 42 top-division titles, faced stiffer-than-expected competition against No. 2 maegashira Hokutofuji (3-1), who was looking for a second-straight win against the Mongolian.
