Host Japan delivered another thunderous display of dominance, winning all four weight classes on the second day of the Tokyo Grand Slam on Saturday.
It was the second day in a row Japan swept the gold medals in its own backyard after claiming five of the top podium spots on the first day of the Tokyo meet.
At 81 kig, 20-year-old Takanori Nagase shredded the competition with four consecutive ippon wins before closing the day with a triumph over reigning world champion Loic Pietri of France for his fifth ippon, deploying a spectacular leg wheel, or "ashi-guruma" technique, to claim his first championship.
