Umeki of Japan won her first international gold medal since claiming her world championships title in 2015 as she defeated France's Madeleine Malonga, a two-time Grand Prix winner, in the final of the women's under 78 kilograms event.

The Japanese defeated Malonga on the ground as she held down the Frenchwoman with a yoko-shiho-gatame hold to win her first Grand Prix gold medal.

Klara Apotekar of Slovenia claimed one of the bronze medals while the other was collected by Japan's Rika Takayama.

In the over 78kg final, Ukraine's Iryna Kindzerska defeated five-time world medallist Megumi Tachimoto of Japan to claim her country’s only medal in Germany.

Tachimoto was making her return from a lengthy injury lay-off and that showed as the 25-year-old Ukrainian, who was fifth at the London 2012 Olympic Games, drove over the accomplished Japanese heavyweight in golden score with a tani-otoshi for a match-winning waza-ari score and her first Grand Prix gold prize.

The bronze medals were shared between Bosnia and Herzegovina's Larisa Ceric and Akira Sone of Japan.

Former World Judo Masters winner Beka Gviniashvili of Georgia won his fifth Grand Prix gold medal on Sunday with an emphatic display that illustrated why he is the rising star of Georgian judo. 

He defeated Russia's Khusen Khalmurzaev in the last 10 seconds of the under 90kg final.

The Rio 2016 Olympian had plenty in reserve and threw with a huge makikomi effort for a waza-ari before seizing the osaekomi in the form of a kuzure-ushiro-kesa-gatame for gold.

Daiki Nishiyama of Japan claimed one of the bronze medals while the other was collected by Slovenian Mihael Zgank.

World bronze medallist Toma Nikiforov of Belgium lost his opening contest in Paris a fortnight ago but bounced back like a true champion to register his second Grand Prix career victory today in the under 100kg event.

The Belgian fighter, whose last international medal was silver at the European Championships almost a year ago, needed just 35 seconds to defeat Aaron Wolf of Japan, who had no choice but to tap out to the shime-waza.

The bronze medals were shared between Russia's Kazbek Zankishiev and The Netherlands' Michael Korrel.

In the final category of the competition, Tokyo Grand Slam silver medallist Kokoro Kageura of Japan unexpectedly defeated his compatriot and Rio 2016 Olympic silver medallist Hisayoshi Harasawa in the over 100kg event.

Kageura, of Tokai University, is still relatively unknown on the IJF circuit but introduced himself to a new audience in his first senior competition outside of Asia.

The 21-year-old countered a weak uchi-mata attempt from his opponent for a waza-ari which proved decisive.

Bronze medals in this category were awarded to both Barna Bor of Hungary and Kazakhstan's Yerzhan Shynkeyev.

The IJF World Judo Tour will now head to Azerbaijan and the 2018 World Championships host city of Baku.
