Mia Ski Resort is a ski area in Nagano, Japan, on slopes between roughly 1,542 and 2,150 m. Its mapped area is about 3.0 km across, with 5 marked runs and 3 lifts (about 6.5 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 250 cm of snowfall a season, 198th of the 397 ski areas we measure in Japan. It swings a lot from year to year: the biggest winter, 2014/15 (321 cm), brought more than twice as much as the leanest, 2015/16 (134 cm). March still brings 61 cm on average, close to January, its snowiest month. Snowfall days are cold, averaging −8.2 °C at mid-mountain, and its snow-quality score ranks 121st 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 |
|---|---|---|---|
| Kisofukushima Ski Resort | 15 km | 231 cm | 865 |
| Yabuhara Kogen | 20 km | 182 cm | 1298 |
| Blue Resort Norikura | 23 km | 317 cm | 421 |
| Shinshu-Matsumoto Nomugitoge Ski Resort | 23 km | 318 cm | 408 |
| Hida Takayama Municipal Ski Resort | 25 km | 354 cm | 277 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 85% of January’s snowfall. That is a gentler fall than the median for ski areas in Japan (52%). In amount, March brings 61 cm, more than the median of 46 cm.
Winter by winter
Across the 12 winters measured, the average is 250 cm, and 6 of them fell short of it. The leanest was 2015/16 with 134 cm; the biggest was 2014/15 with 321 cm (2.4 times as much). For 63% of the 397 ski areas in Japan, the leanest winter was the same 2015/16: bad winters tend to hit a whole region at once.
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.

The shape of the mountain
Which way the slopes face
97% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

- 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.
- How Japan's Early-Bird Lift Tickets Work: At Hakuba Happo-One, Eight of the Nine Need a Japanese ID Card Hakuba Happo-One opened early-bird sales at 10:00 on 1 October. A day costs ¥6,400 against ¥9,800 at the window, 35% off. But every ticket on the list except one needs a My Number Card and a Japanese phone app. A visitor from abroad can buy exactly one of them, at 15% off.
