This season so far (1 Nov to 9 Nov): 1 cm. The average for these dates is under 10 cm, so we do not give a percentage yet. The average is over twelve winters on the same weather model. Across Japan →

The R292 run follows National Route 292, closed to cars in winter. Linked from Aobayama via Onariyama down to Tenguyama, it makes one long descent. The Natsumichi run is named for the summer path that climbed from the hot-spring town to Mount Shirane before there were proper trails. The base is about five minutes by car from town.

The quality score leaves out how much snow falls (it uses temperature, frequency, rain and wind).

What was actually measured nearby

Total snowfall from December to March recorded at the 草津 weather station — 2.2 km from this ski area, 241 m below its mid-slope.

Three-season average460 cm
2023/24650 cm
2024/25449 cm
2025/26280 cm

The figure calculated on this page is 247 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.
