25-26シーズン 無限パウダーの奥利根スノーパーク（2025/12/26）
By: K_ yamanobori · 2025-12-29
Okutone is a ski area in Gunma, Japan, on slopes between roughly 546 and 1,004 m. Its mapped area is about 1.7 km across, with 6 marked runs and 6 lifts (about 5.5 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 198 cm of snowfall a season, 267th of the 397 ski areas we measure in Japan. Its winters are fairly steady; even the leanest, 2025/26 (150 cm), reached 76% of the average. January is usually the snowiest month, with about 69 cm. Weather models read low in the mountains: a Japan Meteorological Agency station 4.9 km away measured 511 cm a winter over the last three seasons, against 207 cm from the model. Snowfall days average −2.6 °C at mid-mountain, and its snow-quality score ranks 274th of 397 in Japan.
Below are links to 2 official live cameras.

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 deliberately excludes how much snow falls — it uses temperature, frequency, rain and wind. Snowing a lot and snowing well are different things.

What was actually measured nearby
Total snowfall from December to March recorded at the みなかみ weather station — 4.9 km from this ski area, 251 m below its mid-slope.
| Three-season average | 511 cm |
| 2023/24 | 410 cm |
| 2024/25 | 708 cm |
| 2025/26 | 415 cm |
The figure calculated on this page is 207 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.

Guides covering Gunma
- Everywhere on Earth You Climb for Snow. Japan Is the One Place You Drive Toward the Sea. Across 3,069 ski areas we measure, height and snowfall move together — +0.58 in France, +0.85 in Germany. In Japan the figure is +0.02. The reason is not that elevation stopped working.
- How Close to Rain Does the Snow Fall? Japan, the Alps and North America Compared We measured how close to freezing the snow already falls at 240 randomly drawn resorts in the Alps and North America, and at all 397 in Japan. Japan is not one place: Honshu is among the most exposed, Hokkaido among the least.
- Why Is Hokkaido's Snow Colder? Latitude, Elevation and Rain Across 397 Japanese ski areas, elevation sets the temperature and latitude does almost nothing to it — inside Honshu, going north is worth nothing at all. What latitude buys instead is the absence of rain.
