Day two of the Judo Grand Slam in Tokyo saw four weight categories take to the tatami and Japan continued their impressive showing by maintaining their unbeaten run.
After Japan won all that was on offer on day one Chizuru Arai maintained the host nation’s stunning start to the competition when she beat world number one Kim Polling of the Netherlands in the -70 kilo division final.
Japan increased their medals haul when World Judo Masters winner and world number four Kana Abe defeated compatriot Miku Tashiro in the -63 kg class.
19-year-old Abe claimed gold after receiving fewer penalties for passivity.
Crowd favourite Riki Nakaya thrilled the home support when he was crowned -73 kilo champion after defeating Rijeka Grand Prix winner Gui-Man Bang of South Korea.
Nakaya clinched the gold medal just after the minute mark, holding down his opponent for the 20 seconds needed for a win with a kami-shiho-gatame.
Takanori Nagase completed Japan’s clean sweep of the gold medals over two days when he beat world champion Loic Pietri of France in the -81 kilo final.
The 20-year-old claimed top spot after throwing Pietri for ippon in the fourth minute.
