The World Championships bronze medallist overcame Paralympic champion Anna Schaffelhuber of Germany, clocking a time of 1min 18.59sec on the Happo-One slopes.

Muraoka beat Schaffelhuber by 0.24 seconds, while Germany’s Anna-Lena Forster was 2.17 seconds back in third.

Muraoka managed to bag a podium in that race too, finishing second in 1:20.32 with the United States’ Laurie Stephens third in 1:26.11.

The results mean that Schaffelhuber leads the super-G World Cup with 340 points, 40 more than Muraoka, who is now tied in second with Austria’s Claudia Loesch.

The final standings will be decided at the World Cup Finals and Pyeongchang 2018 Winter Paralympic Games test event, due to get underway on March 12.

All five technical and speed disciplines will be contested in the South Korean county, including a further two super-G contests.

Peters is second on 240 points, followed by Morii with 230.

Germany’s Andrea Rothfuss continued her winning streak in the women’s standing, claiming wins in both races to cement her lead at the top of the leaderboard.

The world bronze medallist can still be caught though by America's Stephanie Jallen, whose two podium finishes have kept her in contention.

Switzerland’s Robin Cuche came within 0.07 seconds of Salcher’s winning time of 1:13.11 in the second race, while Australia’s Mitchell Gourley was third in 1:13.41.

Salcher now has a 180-point lead at the top of the rankings and is within touching distance of the overall crystal globe.
