All 'official snow depth' figures shown on SnowJapan originate from the ski areas themselves. SnowJapan does not measure or control these figures, and there is no industry-wide standard governing how ski areas report snow depth. A new season of data is typically added to this chart in late spring each year.
During the winter season, current snow depth data, where available, can be found on our daily updated snow depth chart.
