Manza Onsen is a ski area in Gunma, Japan, on slopes between roughly 1,665 and 1,942 m. Its mapped area is about 1.8 km across, with 12 marked runs and 5 lifts (about 5.2 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 255 cm of snowfall a season, 184th of the 397 ski areas we measure in Japan. Its winters are fairly steady; even the leanest, 2025/26 (197 cm), reached 77% of the average. January is usually the snowiest month, with about 79 cm. Snowfall days are cold, averaging −8.7 °C at mid-mountain, and its snow-quality score ranks 43rd 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.

|---|---|---|---|
| Shiga Kogen Yokoteyama Ski Area | 4.1 km | 333 cm | 333 |
| Shiga Kogen Shibutoge Ski Area | 4.1 km | 333 cm | 333 |
| Shiga Kogen Kumanoyu Ski Area | 4.2 km | 333 cm | 333 |
| YAMABOKU Wild Snow Park | 4.9 km | 255 cm | 692 |

Winter by winter
Across the 12 winters measured, the average is 255 cm, and 7 of them fell short of it. The leanest was 2025/26 with 197 cm; the biggest was 2014/15 with 337 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.

What we have measured at Manza Onsen
- Ski and Soak in Japan: Which Ski Areas Have a Hot Spring Source Next Door, and How Hot the Water Is We matched 7,203 analysed hot spring sources to Japan's ski areas. 255 of 397 have one within 5 km, 145 of them at 42 °C or hotter, and 54 have one within 1 km. These are the ski areas that pair top snow with hot water close by, and the ones where the water is strongly acidic.
