Green Valley Kamuro Ski Area is a ski area in Yamagata, Japan, on slopes between roughly 303 and 461 m. Its mapped area is about 0.9 km across, with 7 marked runs and 1 lift (about 2.6 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 277 cm of snowfall a season, 167th of the 397 ski areas we measure in Japan. Its winters are fairly steady; even the leanest, 2019/20 (206 cm), reached 74% of the average. January is usually the snowiest month, with about 98 cm. Weather models read low in the mountains: a Japan Meteorological Agency station 7.1 km away measured 513 cm a winter over the last three seasons, against 280 cm from the model. Snowfall days average −1.7 °C at mid-mountain, close to freezing, so the snow is often heavy, and its snow-quality score ranks 310th 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 |
|---|---|---|---|
| Gionyama Ski Area | 25 km | 321 cm | 401 |
| Onikobe Ski Area | 26 km | 260 cm | 667 |
| Inakawa Ski Area Suberotta | 30 km | 229 cm | 885 |

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 38% of January’s snowfall. That is a steeper fall than the median for ski areas in Japan (52%): the snow here is concentrated early in the season. In amount, March brings 37 cm, less than the median of 46 cm.
Winter by winter
Across the 12 winters measured, the average is 277 cm, and 6 of them fell short of it. The leanest was 2019/20 with 206 cm; the biggest was 2017/18 with 355 cm (1.7 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
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.

What was actually measured nearby
Total snowfall from December to March recorded at the 金山 weather station — 7.1 km from this ski area, 212 m below its mid-slope.
| Three-season average | 513 cm |
| 2023/24 | 412 cm |
| 2024/25 | 597 cm |
| 2025/26 | 530 cm |
The figure calculated on this page is 280 cm.
A weather station is not a ski slope. We picked one at a similar elevation, but it stands in a valley or a village. More snow falls on the mountain above it. We have not tried to guess how much more.

Guides covering Yamagata
- 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%.
- When Is There Snow at Japan's Hot Spring Towns? If you want to sit in an outdoor bath with snow on the ground, the question is when, not just where. We measured the snow depth at 14 Japanese hot spring towns across three winters — arrival, departure, and how many days it is actually deep.
- When Is the Best Time to Ski in Japan? January, measured over twelve winters at 397 ski areas. Last season was not typical — its January ran high and its March ran less than half of normal — so here is the average alongside it, month by month.
