A torii gate stands on the summit of Tategamine at the top of the area, with views across to Mt Ontake and Kiso-Komagatake. The runs lie in a valley, which the resort says keeps them out of much of the wind. The area opened in 1931 and is run by a third-sector company set up with Kiso village.

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 90% of January’s snowfall. That is a gentler fall than the median for ski areas in Japan (52%). In amount, March brings 47 cm, about the same as 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.
