Eight-year-old Chloe Jeffries was killed on Saturday when a snowmobile she was riding overturned in Hakuba Village, Nagano, the tour company who operated the trip said.
The Gold Coast girl was given first aid at the scene and transported to hospital by helicopter but could not be revived, Hakuba Lion Adventure said in a statement.
"The snowmobile tour was conducted with a total of nine snowmobiles, including three guides," the company said.
"During the tour, near an uphill curve along a forest road, the snowmobile ... rode up onto the embankment at the side of the trail.
"The vehicle subsequently overturned. As a result of the overturn, the passenger riding tandem on the snowmobile became trapped beneath the vehicle."
Chloe has been remembered as a very special part of her local community in a tribute posted by her netball association based in Palm Beach.
"She was known for her beautiful nature, her cheeky, infectious smile, and the joy she brought simply by being herself," the South Coast netball Association wrote.
"Above all, Chloe was her big sister Hallee's biggest supporter, always cheering from the sidelines, full of pride, encouragement and love."
Players are being encouraged to wear a ribbon or armband in sparkly pink, Chloe's favourite colour, during the competition's first round of games this weekend.
The Department of Foreign Affairs and Trade confirmed they are providing consular assistance to the family.
Chloe's death adds to a growing number of Australians killed while holidaying at Japanese ski resorts this season.Â
