広島県、恐羅漢スノーパーク全国スキー場巡り第38話。
By: いらっしゃいませ、おじゃまします。 · 2026-04-26
Osorakan Snow Park is a ski area in Hiroshima, Japan, on slopes between roughly 828 and 1,219 m. Its mapped area is about 1.7 km across, with 21 marked runs and 8 lifts (about 9.6 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 116 cm of snowfall a season, 362nd of the 397 ski areas we measure in Japan. It swings a lot from year to year: the biggest winter, 2024/25 (190 cm), brought more than 5 times as much as the leanest, 2015/16 (33 cm). January is usually the snowiest month, with about 40 cm. Snowfall days average −3.7 °C at mid-mountain, and its snow-quality score ranks 355th of 397 in Japan.
Below are links to 2 official live cameras.
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.
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.

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 43% of January’s snowfall. That is a steeper fall than the median for ski areas in Japan (52%): the snow here is concentrated early in the season. In amount, March brings 17 cm, less than the median of 46 cm.

Winter by winter
Across the 12 winters measured, the average is 116 cm, and 7 of them fell short of it. The leanest was 2015/16 with 33 cm; the biggest was 2024/25 with 190 cm (5.8 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.
