Two sets of slopes, Ipponsugi and Yoshizato, meet at the summit. The ski school has a reception desk upstairs in each of the two hotels, one at Ipponsugi and one at Yoshizato. The Yoshizato hotel takes student groups, and in winter it hosts schools on residential ski trips.

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 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.
The most snow falls in January. March brings 30% of January’s snowfall. That is a steeper fall than the median for ski areas in Japan (52%): the snow here is concentrated early in the season. For skiing, though, the amount matters more than the share: March brings 59 cm, more than the median of 46 cm.

These are analyses of hot spring sources, not a list of baths you can visit. They date from 1910 to 2005, many from decades ago, so today’s temperature and chemistry may differ. Names are as recorded in Japanese. Temperature and pH bands follow Japan’s standard for analysing hot springs.
