2026.1.24 爺ガ岳スキー場 猛烈寒波！
By: harumadaski · 2026-01-25
Jiigatake Snow Resort is a ski area in Nagano, Japan. The terrain spans roughly 949–1180 m above sea level. The mapped ski area covers about 1.6 km². Within 2.5 km of the centre, the map shows 13 marked runs and 5 lifts, totalling about 5.6 km of piste. There is no settled snow at the moment — the season has not started here yet. Over the last three winters the ERA5 reanalysis gives it 465 cm of snowfall a season, 103rd (tied) of the 3,112 ski areas we measure worldwide. The model runs well below what resorts report, so the ranking is the meaningful part rather than the centimetre figure. The nearest city of any size is Nagano, about 35 km away. 1 official live camera is linked below. 134 other ski areas lie within 120 km. Snow figures and the Powder Score are recalculated every day.

The tick marks the median across the 395 Japanese ski areas. All four bars run the same way — longer is better.
The quality score deliberately excludes how much snow falls — it uses temperature, frequency, rain and wind. Snowing a lot and snowing well are different things.
Compared with what is nearby

What was actually measured nearby
Total snowfall from December to March recorded at the 大町 weather station — 5.1 km from this ski area, 280 m below its mid-slope.
| Three-season average | 240 cm |
| 2023/24 | 262 cm |
| 2024/25 | 333 cm |
| 2025/26 | 126 cm |
The figure calculated on this page is 465 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.
