Zao Onsen is a resort in Yamagata - Tohoku (Japan) skied between 750 and 1661 metres, with 30 km of pistes and 18 lifts.
The camera shows real visibility and snow on the ground, not the forecast. Snow depth by altitude — 750 to 1661 m — and the days ahead are in the Zao Onsen snow report.
Which lifts and runs Zao Onsen opens is published by the resort every morning and changes with the wind: the upper ones, up to 1661 m, are the most exposed. If the camera is a white blur mid-morning, that is usually why.
