Ryunosuke Haga rounded off a successful International Judo Federation (IJF) Hohhot Grand Prix for Japan as he secured their fifth gold of the event.

The reigning world champion topped the men’s 100 kilogram podium on the final day of action at the Inner Mongolia Stadium in the Chinese city.

In today’s final, he faced-off against Russia’s Kirill Denislov and it proved to be a tight affair as the fight had be decided through a golden score.

However, Haga looked fresh even during the extra period and soon had the victory after his opponent was penalised for a false attack.

Haga’s attention, like all the judokas at the event, will now be the IJF World Championships due to begin in Hungarian capital Budapest on August 28.

Taking home the bronze medals in the men’s 100kg were Kazbek Zankishiev of Russia and Sweden’s Joakim Dvarby.

Haga won a bronze medal at the Rio 2016 Olympic Games in a competition won by the Czech Republic’s Lukas Krpalek.

The man who took gold in the Brazilian city is now fighting in the highest weight class, over-100kg, and in Hohhot he showed that moving up a division is not causing him problems.

He reached today’s final against Mongolia’s Duurenbayar Ulziibayar and the judokas were involved in a thriller.

With 42 seconds left, Uliziibayar scored a waza-ari to take the lead, only for Krpalek with a sumi-gaeshi which led to an osaekomi, causing his opponent to submit.

South Korea’s Kim Sung-min and Andrey Volkov of Russia came third.

The men’s 90kg title was won by Russian judoka Khusen Khalmurzaev, who defeated world number on Aleksandar Kukolj of Serbia in the final.

There was another Russian on the podium in the form of Magomed Magomedov while the other bronze was won by Mongolia’s Altanbagana Gantulga.

There were two women’s weight divisions in competition today.

Han Mi-jin made a perfect debut on the IJF Grand Prix circuit as the 2015 Junior World Championship bronze medallist won the over-78kg category.

She beat the other person who claimed a bronze at that event in Abu Dhabi, the Ukraine’s Yelyzaveta Kalanina, with a waza-ari during the golden score period.

Rounding up the podium were Mongolian Munkhtuya Battulga and Japanese judoka Sara Yamamoto.

Austra’s Bernadette Graf won the women’s 78kg category, seeing off Karen Stevenson of The Netherlands in the final, with Lee Jeong-yun of South Korea and Japan’s Ruika Sato finishing third.
