Yomase Onsen, the hot spring within the ski area, is listed among Nagano Prefecture's 100 sunset spots. From the slopes the Zenkoji Plain spreads out below. A piste is set aside for gate training, and parts of the area are closed off several times each winter for ski races.

The quality score leaves out how much snow falls (it uses temperature, frequency, rain and wind).
Compared with what is nearby
Within 50 km in a straight line. Ski areas in the same weather-model cell (about 30 km across) get the same figure.
