White World Oze Iwakura

ホワイトワールド尾瀬岩鞍
Off season Official site Lift tickets (official)

White World Oze Iwakura is a ski area in Gunma, Japan, on slopes between roughly 963 and 1,575 m. Its mapped area is about 3.7 km across, with 11 marked runs and 11 lifts (about 11 km of piste in all).

Over the last twelve winters the ERA5 weather model gives it 252 cm of snowfall a season, 195th of the 397 ski areas we measure in Japan. It swings a lot from year to year: the biggest winter, 2021/22 (318 cm), brought more than twice as much as the leanest, 2015/16 (158 cm). January is usually the snowiest month, with about 83 cm. Snowfall days average −5.7 °C at mid-mountain, and its snow-quality score ranks 81st of 397 in Japan.

Below is a link to its official live camera.

Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.

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.

Winter by winter

Across the 12 winters measured, the average is 252 cm, and 7 of them fell short of it. The leanest was 2015/16 with 158 cm; the biggest was 2021/22 with 318 cm (2.0 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.
