The 13-year-old led a Japanese sweep of the podium in the women's final in the park event at Fish Mouth Skatepark, which offers third tier points towards qualification for skateboarding's Olympic debut.

Okamoto, leader of the women's Olympic park rankings, scored 50.00 points to secure the gold medal ahead of compatriots Sakura Yosozumi and Kisa Nakamura.

Yosozumi took silver on 45.48 points, while Nakamura was third having amassed 43.87 points.

The American finished comfortably in front of the rest of the field, with Brazilian Luiz Francisco more than four points adrift in second place.
