The yokozuna duo of Harumafuji and Hakuho remained one win back of the leaders on Thursday, the fifth day of the Summer Grand Sumo Tournament.
Hakuho, who is seeking his seventh consecutive title and 35th career Emperor's Cup, improved to 4-1 when he salvaged victory from the jaws of defeat against Aminishiki.
The yokozuna was able to shove the No. 2 maegashira about the ring by slapping at him but could not shove him out. As the slapping continued, Hakuho missed his mark with one shove, lost his balance and spun about with his back to his opponent.
