Japan's Kokomo Murase won the women's snowboarding World Cup big air gold medal with the highest score of all time Friday, with Hiroaki Kunitake securing men's gold for the first time on the circuit.

Beijing Olympic bronze medalist Murase scored 197.00 points at the event's season finale in Copper Mountain, Colorado, reeling off two tricks that have never before been landed in competition en route to her second win of the campaign after her opening-round victory in Switzerland in October.

"I was determined to make the podium as I was competing in just two big air events (at the World Cup this season). I'm really happy to have won both," Murase said.

Murase scored 97.25 with her opening run when she landed a switch frontside triple cork 1260 Indy before getting a near-perfect 99.75 with her second when she stomped a never-been-done backside triple cork 1440 Weddle grab.

The final run only got her 96.25 but she came up with another unseen trick, a switch frontside triple cork 1440 Indy.

"It's been a season like never before. I have added more variation to my tricks and that's really boosted my confidence," Murase said.

Murase's 16-year-old compatriot Mari Fukada won silver with 174.00, followed by Mia Brookes of Britain with 155.75. Japan's Reira Iwabuchi came fifth and Miyabi Onitsuka sixth.

Kunitake, meanwhile, won his maiden World Cup gold with 181.25 after landing a trick that was another first.

Having begun with a switch frontside 1800 Weddle to tail grab for an 86.50, Kunitake nailed a frontside quad cork 1800 Weddle, never seen at the World Cup, with his second for a 94.75.

Sam Vermaat of the Netherlands came second on 169.50 and Redmond Gerard of the United States third on 169.25.
