Japan's Risako Kinjo said her wrestling career had given her a sense of fulfillment after the double Olympic gold medalist announced her retirement at the age of 30 on Sunday.

The four-time world champion, who previously competed under the name Risako Kawai, took gold in the 63kg category in Rio de Janeiro in 2016 and stood on top of the podium on home soil in Tokyo five years later by winning the 57kg class.

Her sister Yukako also claimed wrestling gold in Tokyo, winning the 62kg event.

"I've experienced all the joy that comes from being an athlete," said Kinjo, who won her final world championships title in 2024, two years after she had given birth to her first child. "I feel fulfilled."
