Okutone is a ski area in Gunma, Japan. The terrain spans roughly 546–1004 m above sea level. The mapped ski area covers about 1.7 km². Within 2.1 km of the centre, the map shows 11 marked runs and 6 lifts, totalling about 5.6 km of piste. There is no settled snow at the moment — the season has not started here yet. Over the last three winters the ERA5 reanalysis gives it 207 cm of snowfall a season, 1015th (tied) of the 3,112 ski areas we measure worldwide. The model runs well below what resorts report, so the ranking is the meaningful part rather than the centimetre figure. 2 official live cameras are linked below. 133 other ski areas lie within 120 km. Snow figures and the Powder Score are recalculated every day.

75% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

The tick marks the median across the 395 Japanese ski areas. 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.

| Tanigawadake Tenjindaira Ski Area | 5.9 km | 395 cm | 171 |

What was actually measured nearby
Total snowfall from December to March recorded at the みなかみ weather station — 4.9 km from this ski area, 251 m below its mid-slope.
| Three-season average | 511 cm |
| 2023/24 | 410 cm |
| 2024/25 | 708 cm |
| 2025/26 | 415 cm |
The figure calculated on this page is 207 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.
