Japan's gold medal hopeful Kokomo Murase sank and finished 10th in the women's snowboard slopestyle at the Beijing Winter Games on Sunday while New Zealand's Zoi Sadowski Synnott earned her country's first ever Winter Olympics gold medal.

The 17-year-old Murase missed becoming Japan's youngest-ever female medalist at the Winter Games, scoring 49.05 points, while compatriot Reira Iwabuchi finished fifth with 80.03.

"I'm frustrated I fell in three runs and wasn't able to deliver the tricks I wanted," said Murase, who was the youngest winter X Games gold medalist when she triumphed in the 2018 big air event at the age of 13.

"I want to aim for the next Olympics."

While Sadowski Synnott pulled out the best score of 92.88 in her final run, Julia Marino of the United States was runner-up with 87.68, followed by Australia's Tess Coady on 84.15.

"It probably means more to me to win New Zealand's first Winter Olympic gold, makes me super proud to be a Kiwi," she said.

"I hope that I made them proud and that they'll celebrate for me."

Men's snowboard slopestyle qualification was held later Sunday. Two Japanese riders, Takeru Otsuka and Kaito Hamada, placed sixth and 12th, respectively, to advance to Monday's three-run final.
