Japan's Sakura Yosozumi and Kokona Hiraki took gold and silver in the first ever women's park skateboarding event.
British skateboarder Sky Brown, another one of the sport's bright young stars, won bronze. She beat out Misugu Okamoto for third place, denying Japan a clean sweep in the event.
All three medalists are younger than 20. Yosozumi is 19, Hiraki is 12, and Brown is 13.
Brown, Great Britain's youngest ever Olympian, is now also the country's youngest ever medalist.
With Yosozumi's win, Japan has taken gold in all three skateboarding events so far in Tokyo.
Skateboarding concludes Thursday with the men's park event.
