Akagisan Daiichi Ski Area is a ski area in Gunma, Japan. The terrain spans roughly 1358–1440 m above sea level. The mapped ski area is about 0.3 km across, corner to corner. The map shows 1 marked runs and 1 lift inside the ski area, totalling about 0.1 km of piste. There is no settled snow at the moment — the season has not started here yet. Averaged over the last twelve winters, the ERA5 reanalysis gives it 80 cm of snowfall a season, 2583rd (tied) of the 3,069 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. 123 other ski areas lie within 120 km. Snow figures and the Powder Score are recalculated every day.
Elevation range is estimated by sampling points across the ski area.

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.

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.

Live Cameras
This ski area does not put a camera on its own slopes. What follows are nearby cameras, not the pistes themselves.

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.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Oguna Hotaka Ski Area | 26 km | 252 cm | 712 |
| Kawaba Ski Resort | 27 km | 423 cm | 144 |
| Tambara Ski Park | 28 km | 423 cm | 144 |
| Katashina Ogna Hotaka Snow Resort | 29 km | 252 cm | 712 |
| Katashina Kogen Ski Resort | 30 km | 252 cm | 712 |
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.

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.

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.
- Half the Alps Already Snows Within 2°C of Rain. In Hokkaido It Is 3%. 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.
- Hokkaido's Ski Areas Sit 659 m Lower Than Honshu's and Are Still Colder 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.
