Katashina Ogna Hotaka Snow Resort is a ski area in Gunma, Japan, on slopes between roughly 1,092 and 1,474 m. Its mapped area is about 2.0 km across, with 10 marked runs and 4 lifts (about 5.9 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 252 cm of snowfall a season, 192nd of the 397 ski areas we measure in Japan. It swings a lot from year to year: the biggest winter, 2021/22 (318 cm), brought more than twice as much as the leanest, 2015/16 (158 cm). January is usually the snowiest month, with about 83 cm. Snowfall days average −5.8 °C at mid-mountain, and its snow-quality score ranks 76th 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.

| White World Oze Iwakura | 2.8 km | 252 cm | 712 |
| Katashina Kogen Ski Resort | 2.9 km | 252 cm | 712 |
| Oguna Hotaka Ski Area | 3.2 km | 252 cm | 712 |
| Kawaba Ski Resort | 7.3 km | 423 cm | 144 |

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 60% of January’s snowfall. That is a gentler fall than the median for ski areas in Japan (52%). In amount, March brings 50 cm, about the same as the median of 46 cm.
Winter by winter
Across the 12 winters measured, the average is 252 cm, and 7 of them fell short of it. The leanest was 2015/16 with 158 cm; the biggest was 2021/22 with 318 cm (2.0 times as much). For 63% of the 397 ski areas in Japan, the leanest winter was the same 2015/16: bad winters tend to hit a whole region at once.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

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.
