Japan has ended the International Judo Federation (IJF) Grand Slam in Tokyo in dominant style as the country secured six of a possible eight gold medals on the final day in the capital.

Kano Miyaki recorded her first Grand Slam title in the women's under-48kg category as she led a Japanese podium sweep with Rina Tatsukawa settling for silver while Wakana Koga and world champion Natsumi both won bronze.

Tokyo 2020 and reigning world gold medallist Uta Abe continued Japan's winning streak.

She faced compatriot Ai Shishime in the women's under-52kg final and defeated her after an eight-minute epic with a waza-ari.

They were joined on the podium by countrywoman Kisumi Omori and Mongolia's Sosorbaram Lkhagvasuren.

The women's under-78kg final was then won by Rika Takayama in another all-Japan bout against Shori Hamada.

Their team-mate Mami Umeki clinched a bronze medal alongside Dutch judoka Natascha Ausma.

Akira Sone secured a gold medal sweep of the women's tournaments for her country as she beat another Japanese athlete in the final, in the form of Maya Akiba in the over-78kg contest.

Prior to the deciding match-up South Korean Kim Ha-yun and Lea Fontaine of France won bronze.

The Japanese monopoly carried over to the men's events as Hyoga Ota pocketed the over-100kg gold ahead of silver medal winner Kokoro Kageura and bronze medallist Hisayoshi Harasawa.

Kazakhstan's Galymzhan Krikbay took the final place on the podium with bronze.

Double world champion Joshiro Maruyama of Japan prevailed against compatriot Shinsei Hattori in the under-66kg while Maxime Gobert of France and Mongolia's Baskhuu Yondonperenlei made up the bronze medallists.

South Korean Jeon Seung-beom then became the first to deny a Japanese judoka in a gold medal match as he put Hayato Kondo to the sword in the under-60kg decider.

Kondo's countryman Genki Koga secured a bronze alongside Jeon's compatriot Lee Ha-rim.

Italy's Gennaro Pirelli then followed in Jeon's footsteps and beat Japan's Kentaro Iida in the under-100kg final.

Kaito Green and Kotaro Ueoka completed the Japanese medal haul with bronzes.

Overall, the country finished atop the standings by a distance with 12 gold, 12 silver, and 15 bronzes.
