Double Olympic medallist Amandine Buchard won her fifth International Judo Federation (IJF) Grand Slam gold in Paris after defeating fellow European champion Distria Krasniqi.

Frenchwoman Buchard beat the Kosovar in the final bout of the women's under-52-kilograms division in front of a home crowd at the Palais omnisports de Paris-Bercy.

She added the title to her Grand Slam triumphs in Abu Dhabi, Budapest, Osaka and Baku as well as a Tokyo 2020 gold medal in the mixed team event and a silver in her weight class in Japan.

Krasniqi won gold at the Tokyo Games while both athletes were triumphant at the European Judo Championships in Lisbon last year.

Japan's Natsumi Tsunoda won her first Grand Slam in more than five years after defeating Baasankhuu Bavuudorj of Mongolia in the women's under-48kg division.

Tsunoda beat compatriot Wakana Koga, France's Blandine Pont and Ukraine's Anastasiia Balaban on her way to the gold medal match.

There was more joy for Japan in the men's under-60kg.

Ryuju Nagayama won a remarkable eighth Grand Slam title after defeating Seung-beom Jeon of South Korea in the final bout.

Karamat Huseynov of Azerbaijan, South Korean Har-im Lee and Dilshodbek of Uzbeksitan all stood in his way prior to the final.

Luka Mkheidze of France and Georgian Jaba Papinashvili took home the bronze medals.

Bashku Yondonperenlei bagged Mongolia's first gold medal of the event after beating pre-tournament favourite An Ba-ul of South Korea in 7min 12sec in the men's under-66kg final.

Georgia's Vazha Margvelashvili fell in the semi-final to Yondonperenlei and took home a bronze medal along with Ryoma Tanaka of Japan.

Margvelashvili's compatriot Lasha Shavdatuashvili secured gold in the men's under-73kg category.

The London 2012 gold medallist defeated 2017 world champion Soichi Hashimoto of Japan.

It was his first Grand Slam win since the Abu Dhabi event in October 2018.

Haruka Funakubo beat Momo Tamaoki in an all-Japanese final in the women's under-57kg while Japan's Nami Nabekura also prevailed against compatriot Masako Doi in the women's under-63kg final.
