Hisayoshi Harasawa, Daiki Nishiyama and Megumi Tachimoto won their respective weight categories at the Judo Grand Slam on Sunday.

In the men's division on the final day of the meet, Harasawa won the over-100 kg title and Nishiyama the 90 kg, while Tachimoto was the only Japanese woman to win in the over-78 kg in an Olympic qualifier for Japan's judoka at AccorHotels Arena.

Harasawa defeated his Israeli rival Or Sasson in the final to capture his seventh consecutive international title since November 2014.

"I fought wanting to get a leg up on him," the 23-year-old Harasawa said of Sasson, who ousted world No. 2 Ryu Shichinohe in the semifinal by ippon. Shichinohe finished fifth.

Nishiyama beat Alexandre Iddir of France in the 90-kg final.

"It wasn't the greatest bout but I'm a step closer to the Olympics than before. It's been a while since I last won so I'm happy," Nishiyama said.

In the women's over-78 kg final, Tachimoto, who was upset in the final at last summer's world championships, beat her Chinese opponent Ma Sisi.

Tachimoto's sister Haruka lost to South Korea's Kim Seong-yeon in the 70-kg final to settle for second, keeping alive her hopes for a second straight Olympic appearance.
