Kaminokuni Chomin Ski Area is a ski area in Hokkaido, Japan, on slopes between roughly 61 and 115 m. Its mapped area is about 0.4 km across, with 4 marked runs and 3 lifts (about 0.5 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 240 cm of snowfall a season, 209th of the 397 ski areas we measure in Japan. It swings a lot from year to year: the biggest winter, 2024/25 (337 cm), brought more than twice as much as the leanest, 2016/17 (156 cm). January is usually the snowiest month, with about 77 cm. Snowfall days average −1.6 °C at mid-mountain, close to freezing, so the snow is often heavy, and its snow-quality score ranks 307th 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.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Furusatonomori Ski Area | 17 km | 159 cm | 1553 |
| Niyama Kogen Ski Area | 38 km | 155 cm | 1601 |

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 48% of January’s snowfall. That is in line with the median for ski areas in Japan (52%). In amount, March brings 37 cm, less than the median of 46 cm.
Winter by winter
Across the 12 winters measured, the average is 240 cm, and 8 of them fell short of it. The leanest was 2016/17 with 156 cm; the biggest was 2024/25 with 337 cm (2.2 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

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 Hokkaido
- A Historic El Niño Is Forecast. Here Is What the Last Big One Did to Japan's Snow. NOAA gives a very strong El Niño better than a 90% chance this winter. We measured every Japanese ski area across the last 12 winters: El Niño winters ran 88% of normal, and the strongest of the twelve left Japan at 63%. But Hakuba held 92% of its average that winter while Niseko fell to 57%.
- Which Famous Ski Resorts Actually Get the Most Snow? 24 Names, Measured Niseko is 526th in the world for snowfall. Zermatt is 554th, Jackson Hole 924th, Aspen 1,201st. Measured identically across 3,069 ski areas, the names everyone books and the places it actually snows turn out to be two different lists.
- Australia Just Had Its Worst Season in Twenty Years. Here Is What Japan's 12-Winter Record Says About Booking It Instead. Snow depth at Spencers Creek peaked at 94.5 cm, the third lowest since 1954, and resorts closed in August. Our own measure — snowfall, not depth — puts Australia at 50% of its 12-year average. The gap between those two numbers is the story: it was the warmth, not only the lack of snow. New Zealand, meanwhile, finished at 108% of normal.
