Not open yet for 2026/27. We have not yet found an official opening date. The snowfall below is a model figure and does not mean the slopes are skiable.
A weather-model figure, worked out the same way for every ski area, and lower than what actually falls. Use it to compare ski areas, not against the resort’s own totals. How we measure →
This season so far (1 Nov to 9 Nov): 8 cm. The average for these dates is under 10 cm, so we do not give a percentage yet. The average is over twelve winters on the same weather model. Across Japan →

The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure
Next door is the Hokkaido Greenland amusement park, which opens each year in late April. In winter the neighbouring hill becomes a ski area, run by the same company, Greenland Resort. The downhill runs face out over the Ishikari Plain below.

Counted from the runs and lifts drawn on OpenStreetMap, within the boundary of the ski area. These are not the resort’s own published figures.
Only 14% of the vertical on the runs descends to the north or east. The most common direction is west (86%).

Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
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 leaves out how much snow falls (it uses temperature, frequency, rain and wind).
Within 50 km in a straight line. Ski areas in the same weather-model cell (about 30 km across) get the same figure.

The most snow falls in December. March brings 63% of January’s snowfall. That is a gentler fall than the median for ski areas in Japan (52%). For skiing, though, the amount matters more than the share: March brings 29 cm, less than the median of 46 cm.
Across the 12 winters measured, the average is 164 cm, and 7 of them fell short of it. The leanest was 2019/20 with 112 cm; the biggest was 2024/25 with 219 cm (2.0 times as much). For 63% of the 397 ski areas in Japan the leanest winter was 2015/16; here it was a different one.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

These are analyses of hot spring sources, not a list of baths you can visit. They date from 1910 to 2005, many from decades ago, so today’s temperature and chemistry may differ. Names are as recorded in Japanese. Temperature and pH bands follow Japan’s standard for analysing hot springs.

Japan Lift Ticket Prices for 2026/27: What a Day Costs at Twelve Big Resorts, and the Weeks It Costs HalfWe checked the 2026/27 adult day ticket on each resort's own site.

For those cheap spring weeks, we add which way each resort's slopes face.
