"El Niño" / "La Niña" columns: average over those winters (only with 3+ seasons of data)
How to read these numbers
- Days with JMA AMeDAS daily snowfall (0:00–24:00) of 15 cm+ count as JAPOW, 50 cm+ as DEEP POW (DEEP POW days are included in JAPOW; values over 200 cm are excluded as errors).
- A season is November to April; 21 seasons from 2005-06 to 2025-26. Averages use only seasons with data; stations with fewer than 15 seasons are left out of the average ranking. One season can be lucky or unlucky; a 20-year average shows where it reliably snows.
- The station is the AMeDAS chosen for each resort by distance and elevation difference — the same one behind "24h snow" on the top page and resort pages. Resorts sharing a station have the same numbers, so they share one row.
- Values JMA flags as incomplete (some hourly data missing) are counted as published. Seasons with no snow observation, or with a station move or instrument change (the red lines in JMA's tables), are shown as no data (hatched in the charts). Nothing is estimated.
- Most stations are near the base, so the upper mountain often gets more. Numbers are shown even for years when a resort was not operating.
