Snowfall days average −3.8 °C at mid-mountain, and its snow-quality score ranks 157th of 397 in Japan.

The tick marks the median across every Japanese ski area we measure. All four bars run the same way — longer is better.

The quality score deliberately excludes how much snow falls — it uses temperature, frequency, rain and wind. Snowing a lot and snowing well are different things.
