Okutadami Maruyama Ski Resort
Okutadami Maruyama Ski Resort is a ski area in Niigata, Japan. The terrain spans roughly 685–1160 m above sea level. The mapped ski area covers about 2.1 km². Within 2.5 km of the centre, the map shows 13 marked runs and 5 lifts, totalling about 6.3 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 796 cm of snowfall a season, 1st 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. The nearest city of any size is Niigata, about 86 km away. 1 official live camera is linked below. 128 other ski areas lie within 120 km. Snow figures and the Powder Score are recalculated every day.
Elevation range is estimated by sampling points across the ski area.

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
95% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

How much snow it gets
Measured by us across 3,112 ski areas by one identical method. These are not the resort’s own published figures.
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.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Oze Hinoemata Onsen Ski Resort | 20 km | 459 cm | 108 |
| Aizu Kogen Takahata | 21 km | 459 cm | 108 |
| Tadami Ski Area | 22 km | 484 cm | 80 |
| Muikamachi Hakkaisan | 23 km | 738 cm | 10 |
| Yakushi Ski Area | 23 km | 586 cm | 47 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 40% of January’s snowfall. That is a steeper fall than the median for ski areas in Japan (51%): the snow here is concentrated early in the season. For skiing, though, the amount matters more than the share: March brings 105 cm, more than the median of 45 cm.
