American snowboarders enjoyed much success on Sunday, the final day of the Asahikawa World Cup meet, while Japanese teenager Daisuke Murakami hinted at his potential with a fifth-place finish in the men's half-pipe competition.
Californian Tommy Czeschin dominated in the men's half-pipe, scoring a huge 48.4 on his first run to leave Swedish pair Magnus Sterner and Markus Jonsson way behind at Santa Present Park in Hokkaido.
Sapporo schoolboy Murakami, meanwhile, earned 42.4 points for his first run, which was good enough for third until Sterner and Jonsson posted 43.1 and 42.8 in the second round.
Meanwhile, the women's half-pipe was won by American Gretchen Bleiler, who secured her first career World Cup victory, thanks to a solid second run worth 41.3 points.
She finished 0.4 points over France's Doriane Vidal.
