13-year-old Olympic skateboarder Momiji Nishiya becomes one of the youngest gold medal winners ever

At 13 years old, skateboarder Momiji Nishiya of Japan just became one of the youngest gold medal winners ever at the Olympic Games. The girls standing by her side on the podium? Also teenagers. 

Nishiya took home the gold Monday in the women's street competition — which debuted in Tokyo for the very first time. It sealed her nation's fate as the current dominating force in skateboarding, following a win by Yuto Horigome in the men's competition the day prior. "I welled up in tears because I was beyond happy," Nishiya said after her win, which took place in a nearly empty sports park.
