The concluding contest at the Japanese Chiba Port Arena – close to where the Tokyo 2020 competition will be held – provided the greatest drama, as South Korea's Kyo-don In found a way to beat Russia's Vladislav Larin in the final seconds of their men's +80kg final.

Larin had the height advantage but In – nicknamed "The Bear" – looked more powerful.

As the two men reached the third and final round it was all square at 3-3, but the Russian moved ahead 5-3 thanks to two connecting punches.

However, with just seconds left, In unleashed a heel hook kick that shaved Larin's head – and won him both the fight, and the gold, 6-5.

That was the second Korean gold of the night, following Jun Jang's victory over Armin Hadipour Seighalani of Iran in the men’s -58kg final.

A flurry of points after two nondescript rounds saw the Korean win 22-14.

Bronzes went to Adrian Vicente Yunta of Spain and Vito Dell'Aquila of Italy.

In the men's +80kg class, bronzes went to Radik Isaev of Azerbaijan and Iran's Sajjad Mardan.

In the women's -67kg, France's Magda Wiet Henin won her first Grand Prix gold after overcoming Matea Jelic of Croatia.

Jelic dominated the centre of the mats and looked dangerous with a high kick, but round one ended 2-0 to Wiet Henin.

The pace slowed in the second round, but near its conclusion Jelic landed a spin back kick to the torso. 

The third round began with the score at 4-4, when Wiet Henin edged one point ahead with a punch.

With 10 seconds left, the Croatian launched an all-out attack, but despite a head kick that looked like it connected, the board remained at 5-4.

Bronzes went to China's Yunfei Guo and Uzbekistan's Nigora Tursunkulova.

Tomorrow's third and final day sees the women's -49kg and men's -80kg classes.
