In the men's bracket, world champions Daiki Kamikawa (over 100 kg) and Takamasa Anai (100 kg) won their first two rounds to safely book their spots in the final four.

Double world champion Mika Sugimoto and world bronze medalist Akari Ogata reached the semis in the over 78 kg and 78 kg, respectively, in women's action.

Kamikawa, who deployed an inner leg sweep for an easy ippon over Zahid Iqbal of Pakistan in his first match, swept Kyrgyzstan's Iurii Krakovetskii to the floor to make the top four.

Anai, scored inner leg ippon wins against Zein Tamra of Lebanon in his first match and Iran's Javad Mahjoub in the second.
