Weather Data Source
Snow depth and temperature data from the nearest JMA AMeDAS station.
Quickly judge whether this resort fits your trip. See how snowy it gets on average, how long the season runs, and whether powder days are rare or common here.
7-Day Forecast
Decide if this week is worth a trip. Check the snowfall column first: fresh snow in the next day or two is the clearest sign of good conditions.
Powder Days
Find the month most likely to deliver powder. Higher numbers mean better odds. Each cell counts powder days — days with snowfall over your chosen threshold. Turn on the quality filter to keep only the cold, dry days.

Snowfall Consistency
Avoid booking during historically dry spells. Scan the grid to spot weeks that tend to go without snow, then plan your trip around the more reliable windows.

Snow by ENSO Phase
El Niño and La Niña cycles shift global weather patterns and noticeably affect snowfall in Hokkaido. La Niña winters tend to be colder and snowier; El Niño winters tend to be warmer and drier. The averages below are based on historical seasons at this resort.

Powder Reliability Leaderboard
The score tells you how reliably this resort delivers powder, not just in a great season but across many seasons. It combines four factors measured from historical data: how often powder days actually happen, how consistently the snowpack builds and holds depth, how dry and light the snow tends to be, and how often wind ruins powder days. A high score means your chances of hitting good snow are strong across a typical trip, not only during lucky windows.
How scores are calculated
average powder days per season, where a powder day has ≥ 20 cm of new snow from either the weather station OR the resort's own day-over-day depth gain (whichever catches it). Normalised to a per-window ceiling (20 days in peak season, 30 over the whole season).
how consistently the resort holds a deep base. For each season, the share of reported days (Dec 15 – Mar 31) with ≥ 150 cm of resort-reported on-mountain depth scores on a smooth scale — from 0 at ≤ 40% of days deep to full credit at ≥ 55% — then averaged across seasons. Adapted from Witmer 1986 / Abegg 1996; uses on-mountain depth, not the valley station.
fraction of snowfall days where ERA5 daily mean temperature ≤ −5°C at resort elevation, a proxy for dry, high snow-to-liquid-ratio powder (Kuchera & Ely 2004). ERA5 temperature is lapse-rate corrected to each resort's mid-point elevation. Surface temperature is an approximation of the full vertical profile.
fraction of powder days calmer than the resort's own typical winter wind (below its 75th-percentile ERA5 wind). A relative anchor is used because absolute ERA5 grid wind reflects the model's 9 km terrain cell, not on-slope sheltering. Weighted low and best read as a hint, not a ranking factor.
