Japanese judoka Uta Abe triumphed in the women's 52 kg category in Tokyo on Sunday, hours before her brother, Hifumi, took gold in the men's 66 kg final, making history as the first siblings to win gold medals on the same day and bringing Japan's gold haul for the day to four and its overall total to five.

Uta, 21, dominated her bouts in the 52 kg category, but was taken deep into Golden Score overtime in the final against Amandine Buchard of France, eventually pinning her down on her back and holding on for the win.

In the men's final, Hifumi Abe, 23, defeated Georgia's Vazha Margvelashvili to take gold. Bronze medals went to Baul An of South Korea and Daniel Cargnin of Brazil.
