Kokusetsu Horotachi Ski Area is a ski area in Hokkaido, Japan, on slopes between roughly 155 and 337 m. Its mapped area is about 0.9 km across, with 4 marked runs and 1 lift (about 2.9 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 250 cm of snowfall a season, 197th of the 397 ski areas we measure in Japan. Its winters are fairly steady; even the leanest, 2019/20 (198 cm), reached 79% of the average. December brings as much snow as January here (86 and 65 cm on average). Snowfall days average −5.8 °C at mid-mountain, and its snow-quality score ranks 97th 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.
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.
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 |
|---|---|---|---|
| Wassamu Higashiyama Ski Resort | 23 km | 217 cm | 978 |
| Ashimoi Kanko Takaho Ski Area | 26 km | 225 cm | 913 |
| Pippu Ski Slopes | 31 km | 220 cm | 953 |

Month by month, the most snow falls in December. March brings 68% of January’s snowfall. That is a gentler fall than the median for ski areas in Japan (52%). In amount, March brings 44 cm, about the same as the median of 46 cm.
Across the 12 winters measured, the average is 250 cm, and 6 of them fell short of it. The leanest was 2019/20 with 198 cm; the biggest was 2017/18 with 340 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.
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.
59% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
