Olympic champion siblings Uta and Hifumi Abe led a Japanese gold rush Sunday at judo's Tokyo Grand Slam.
The host nation added five gold medals on the final day of the two-day tournament, with Natsumi Tsunoda, Ryuju Nagayama and Miku Takaichi also topping the podium at Tokyo Metropolitan Gymnasium.
The 23-year-old Uta needed only a minute to clinch the women's 52-kilogram final, executing an ashi-waza foot technique to defeat France's Astride Gneto by ippon.
Older brother Hifumi, 26, was almost as quick to wrap up the men's 66-kg decider, toppling Mongolia's Baskhuu Yondonperenlei in 71 seconds for an ippon victory.
Both siblings will aim to go back-to-back as Olympic champions next summer in Paris, having already secured selection for the Japanese team.
"I want to do everything necessary to make sure I win once more on the Olympic stage in Paris," Uta said. "I'm still not satisfied with where I am. I want to get stronger and make sure I definitely win for the second time in a row."
Tsunoda, who is also set for an Olympic berth, was ruthless on her way to winning the women's 48-kg class. She won all four of her matches by ippon and took just 26 seconds to submit Spain's Julia Figueroa in the final.
In the fiercely contested men's 60-kg division, Nagayama took a big step toward Paris with an ippon win over Tokyo Games gold medal-winning compatriot Naohisa Takato.
The final was paused at the start of golden score so that Takato could receive treatment for a cut. The Olympic champion resumed with his face heavily bandaged but lasted just 23 seconds before Nagayama executed the winning move.
In another all-Japanese final, Takaichi defeated Kirari Yamaguchi with a golden-score waza-ari to secure the women's 63-kg crown.
