Akagisan Daiichi Ski Area is a ski area in Gunma, Japan, on slopes between roughly 1,358 and 1,440 m. Its mapped area is about 0.3 km across, with 1 marked run and 1 lift (about 0.1 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 80 cm of snowfall a season, 386th of the 397 ski areas we measure in Japan. It swings a lot from year to year: the biggest winter, 2024/25 (118 cm), brought more than twice as much as the leanest, 2025/26 (49 cm). March is usually the snowiest month, with about 25 cm. Snowfall days average −5.7 °C at mid-mountain, and its snow-quality score ranks 294th of 397 in Japan.
Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.
Elevation range is estimated by sampling points across the ski area.
How much snow it gets
Measured by us across 3,069 ski areas by one identical method. 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 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
Within 50 km straight line. Measured the same way, so the ranks compare directly. Ski areas a few kilometres apart share a weather grid cell and can return the same figure.

| Kawaba Ski Resort | 27 km | 423 cm | 144 |
| Tambara Ski Park | 28 km | 423 cm | 144 |

When it falls, and how winters differ

Winter by winter
Across the 12 winters measured, the average is 80 cm, and 7 of them fell short of it. The leanest was 2025/26 with 49 cm; the biggest was 2024/25 with 118 cm (2.4 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
Runs and lifts
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.

The shape of the mountain
Which way the slopes face
100% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

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.
