Shohei Ono staged an upset against London Olympic silver medalist Riki Nakaya to win the men's 73-kg final on the second day of the Tokyo Grand Slam on Saturday.
A day after Japan pulled off a gold-medal sweep of the medals, representatives from the host nation reached three finals and won two of the four weight classes contested at Yoyogi National Gymnasium.
Twenty-year-old Ono, this year's Kodokan Cup winner, was unstoppable with his fiery foot techniques as he scored ippon victories in all five of his matches en route to his first Grand Slam title victory.
