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): 19 cm, 145% of the average for the same dates. 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
A moving carpet carries skiers from the car park up to the slopes. The Orange and Red B courses and the tree-run zones are left ungroomed, and helmets are compulsory in the tree runs. On the beginner Green B course, the Sea of Japan opens up straight ahead after a wide bend.

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.
92% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

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.

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. At the window it runs from ¥7,000 at Akakura Kanko to ¥16,700 at Rusutsu. Buying online saves up to ¥3,500, and the first and last weeks of the season cost up to half. For those cheap spring weeks, we add which way each resort's slopes face.
