Kokoro Kageura defeated Rio Olympic silver medalist Hisayoshi Harasawa in an all-Japan final to win the men's over-100 kg title at the Dusseldorf Grand Prix in Germany on Sunday.

On the final day of action at Mitsubishi Electric Halle, Asian Championships winner Kageura claimed a yusei decision win over Harasawa, who was appearing in his first meet since the Rio Games and advanced to the final by scoring three ippon in his earlier bouts.

"I was looking for an opportunity to counter and it went as planned," said the 21-year-old Kageura, who received a waza-ari for countering an uchimata attack with an uchimata-sukashi hand-throwing technique.
