But fellow yokozuna Asashoryu suffered an opening day shock defeat at the hands of komusubi Aminishiki.
Hakuho unleashed a series of shoves after the faceoff and stepped away to get a good look at his opponent before moving in for a firm belt grip and squeezing the komusubi over the edge in textbook fashion at Aichi Prefectural Gymnasium.
