After placing fifth at the PyeongChang Winter Olympic Games last month, there was hardly any rest for the 23-year-old, who also finished fifth in the single moguls event on Saturday.
Cox was tempted to wrap up her massive season after the 2018 Games, but was attracted to one last hit out in Japan.
“It feels so great to be back on the podium,” she said after Sunday’s dual event.
“I almost finished the season after the Games, but I had some fire in me and I love this event so I decided to come here and compete.
“The atmosphere in Tazawako is crazy for the World Cup. The event attracts a lot of people from the Akita region and the crowd really get behind the sport. So it’s an amazing place to be on the podium.”
“Being the first competition post Olympics, there were more skiers here who didn’t make the Games but were fired up and ready to go. Dual moguls is always really exciting for us as athletes and everyone was having a great time pushing the speed.”
The duals format sees two skiers go head-to-head in elimination rounds where each winner advances to the next round until there are only two athletes left.
Cox lined up against USA’s Tess Johnson in the fourth round for a shot at the top spot on the podium. Johnson’s put down a blinder final run and the 17-year-old claimed the gold medal in what was her very first World Cup podium.
Cox’s Tazawako results see her move into second place on the overall women’s moguls World Cup standings for the 2017/18 season.
“Stoked to creep back up to second on the overall standings even with skipping the last World Cup before the Games,” she said.
France’s Olympic champion Perrine Laffont still stands as world number one on 527 points after winning the single Tazawako event and placing fifth in the duals. Cox sits behind her on 467 points, just six points ahead of USA’s Jaelin Kauf.
Laffont won gold in the single event, ahead of 2018 Olympic silver medallist Justine Dufour-Lapointe, from Canada, and USA’s Keaton McCargo in bronze.
In the men’s event, Australia’s PyeongChang Olympic bronze medallist Matt Graham was unable to return to his medal-winning form, placing 15th in the single moguls and 17th in the dual moguls.
Japan’s Ikuma Horiashima won double gold in both the single and dual events in front of an energetic home crowd. Olympic Champion Mikael Kingsbury had to settle for second in both events, ahead of Kazakhstan’s Dmitriy Reikherd who won double bronze.
The event in Japan marked the end of the season for Cox and Graham, who will join the rest of the Australian Mogul Skiing Team on a well-deserved break.
