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 29% 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 76 cm, more than the median of 46 cm.

A weather station is not a ski slope. We picked one at a similar elevation, but it stands in a valley or a village. More snow falls on the mountain above it. We have not tried to guess how much more.

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.
