Judoka Hisayoshi Harasawa clinched his first international crown in three years on Sunday when he won the men's over 100-kg title on the final day of the Dusseldorf Grand Slam.

Japan topped the medal tally by winning nine of 14 gold medals available at the three-day tournament at the ISS Dome, with Rio Olympic silver medalist Harasawa capping the week with an ippon triumph over Russia's Inal Tasoev in the heavyweight final.

"I couldn't help but execute (the uchimata inner thigh throw)," said Harasawa, who won four bouts to reach the final.
