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. The terrain spans roughly 828–1219 m above sea level. The mapped ski area covers about 1.7 km². Within 2.5 km of the centre, the map shows 21 marked runs and 8 lifts, totalling about 9.6 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 133 cm of snowfall a season, 1772nd (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. 13 other ski areas lie within 120 km. Snow figures and the Powder Score are recalculated every day.

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.

When it falls, and how winters differ
