Kokusetsu Horotachi Ski Area

ほろたちスキー場

8 / 100 Powder Score

No Snow 🌦️ Official site

Kokusetsu Horotachi Ski Area is a ski area in Hokkaido, Japan. The terrain spans roughly 155–337 m above sea level. The mapped ski area covers about 0.9 km². Within 2.5 km of the centre, the map shows 4 marked runs and 1 lift, totalling about 2.9 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 256 cm of snowfall a season, 694th (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. 38 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.
