When Japanese wrestler Risako Kawai won her second straight Olympic gold medal at the Tokyo 2020 Games on Thursday, it was her sister Yukako she turned to wave at, who had won her gold a day before.

Risako, 26, and Yukako, 23, both won their categories in women's freestyle wrestling, singing the national anthem at the podium two days in a row.

"I found her face in the cheering crowd and I said "I did it!" a jubilant Risako told reporters after the medal ceremony.
