Japan's Yukako Kawai won a wrestling world championship bronze medal on Friday in the women's 62-kilogram division to complement a gold medal won by her sister the day before.

Yukako's victory in her bronze medal match against North Korea's Rim Jong Sim earned her a spot on Japan's team to next year's Tokyo Olympics alongside her older sister Risako, who won the 57-kg division.

Risako had reached the worlds by defeating Japan's four-time Olympic champion Kaori Icho, and her sister's bronze medal meant there was no chance that Icho might be selected for the Olympic team to wrestle in the heavier weight class.

By booking their spots in the 2020 Olympics, the Kawais will become the first Japanese sister act to compete together in the Olympics since Icho and her older sister Chiharu took part in the 2004 and 2008 Olympics.
