Teenager Urara Ashikawa and veteran Mai Murakami both won gold for Japan on the final day of the world artistic gymnastics championships on Sunday, while former Olympic all-around champion Kohei Uchimura failed to make the medals podium.

Murakami, this summer's Olympic women's floor exercise bronze medalist, who earned two medals on the final day, announced afterward that the worlds would be her final competition.

"I'm retiring today," Murakami said. "I think at the very end I was able to grasp that moving moment in the form of a gold medal."
