Olympic gold medalist Uta Abe continued her domination of the women's 52-kilogram division Sunday at the International Judo Federation's Grand Slam Tokyo, beating two-time world champion Ai Shishime in an all-Japanese final.
Cheered on by older brother and fellow Tokyo Olympic champion Hifumi, the 22-year-old Abe went on the offensive early but met fierce resistance from the 28-year-old Shishime at the Tokyo Metropolitan Gymnasium.
After entering golden score, the contest came to an anti-climactic end when Shishime incurred her third shido penalty.
Abe, who is also the reigning world champion, said she felt "about 85 percent" while still working her way back to full strength following surgery on both shoulders last year.
"I want to show everyone an even stronger version of myself by the time of the Paris Olympics (in 2024)," she said as she clinched her place for the world championships next May in Doha.
