Katashina Ogna Hotaka Snow Resort is a ski area in Gunma, Japan. The terrain spans roughly 1092–1474 m above sea level. The mapped ski area covers about 2.0 km². Within 1.4 km of the centre, the map shows 11 marked runs and 4 lifts, totalling about 5.9 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 259 cm of snowfall a season, 669th (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. 1 official live camera is linked below. 128 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.

How much snow it gets
Measured by us across 3,112 ski areas by one identical method. These are not the resort’s own published figures.
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
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 |
|---|---|---|---|
| White World Oze Iwakura | 2.8 km | 259 cm | 669 |
| Katashina Kogen Ski Resort | 2.9 km | 259 cm | 669 |
| Oguna Hotaka Ski Area | 3.2 km | 259 cm | 669 |
| Kawaba Ski Resort | 7.3 km | 449 cm | 116 |

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 (51%). In amount, March brings 49 cm, about the same as the median of 45 cm.
