Kaminokuni Chomin Ski Area is a ski area in Hokkaido, Japan. The terrain spans roughly 61–115 m above sea level. The mapped ski area covers about 0.4 km². Within 2.5 km of the centre, the map shows 4 marked runs and 3 lifts, totalling about 0.5 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 294 cm of snowfall a season, 516th (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. 14 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 |
|---|---|---|---|
| Furusatonomori Ski Area | 17 km | 199 cm | 1095 |
| Niyama Kogen Ski Area | 38 km | 176 cm | 1297 |
| Greenpia Onuma | 41 km | 187 cm | 1208 |
| Hakodate Nanae Snowpark | 49 km | 178 cm | 1282 |
When it falls, and how winters differ

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.
