Japan's Sara Dosho, who won the women's 69-kilogram wrestling gold at the 2016 Rio de Janeiro Olympics, announced Thursday she will retire.

Recalling her athletic career that she began at age 7, the 28-year-old Dosho wrote on Twitter she "has dedicated everything to wrestling" and "can proudly say that I have given my all" to the sport.

Dosho has not competed since losing her 68-kg division bronze-medal match and finishing fifth at the Tokyo Games two years ago.

She will leave her position with her current company at the end of March. Dosho will take up a sports promotion role with the board of education in her central Japan hometown of Matsusaka, Mie Prefecture, a source with knowledge of the matter said.

A strong tackler, Dosho won eight straight national championships starting in 2011. She underwent left shoulder surgery in 2018.

"I will continue doing my best during this new stage, making the most of what I have cultivated so far," she tweeted.
