Four-time Olympic wrestling champion Kaori Icho will return to competition with the aim of earning selection for the 2020 Tokyo Games, sources said Tuesday.

Icho, 34, who has not competed since winning the 58-kilogram division at the 2016 Rio de Janeiro Olympics, is expected to enter the All Japan Women's Open Championships in Mishima, Shizuoka Prefecture, on Oct. 13 to 14.

Winners of the competition advance to the All Japan Championships in December, which in turn serve as the qualifier for the World Championships next year.

The Japan Wrestling Federation earlier this year acknowledged that Icho had suffered power harassment at the hands of former JWF development director Kazuhito Sakae.

Sakae resigned from the JWF in April after a third-party panel of lawyers confirmed four instances in which he had harassed Icho.

The first woman in any sport to win individual gold at four consecutive Olympics, Icho is reportedly eyeing competing in a lighter division than 58 kg in Tokyo.
