Not open yet for 2026/27. We have not yet found an official opening date. The snowfall below is a model figure and does not mean the slopes are skiable.
A weather-model figure, worked out the same way for every ski area, and lower than what actually falls. Use it to compare ski areas, not against the resort’s own totals. How we measure →

The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure
A cable car runs from the basement of the Gateau Kingdom Koumi hotel to the Edelweiss restaurant at the foot of the slopes. The runs take their names from Swiss peaks such as the Eiger, the Jungfrau and the Mönch. Next to the hotel, the Hoshizora-no-Yu bath is fed straight from its hot spring and is open to day visitors.

Counted from the runs and lifts drawn on OpenStreetMap, within the boundary of the ski area. These are not the resort’s own published figures.
96% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
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).
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 March. March brings as much as January, or more. In amount, March brings 49 cm, about the same as the median of 46 cm.
Across the 12 winters measured, the average is 136 cm, and 6 of them fell short of it. The leanest was 2025/26 with 83 cm; the biggest was 2023/24 with 176 cm (2.1 times as much). For 63% of the 397 ski areas in Japan the leanest winter was 2015/16; here it was a different one.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

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.
