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): 9 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
Hirosaki City runs this ski area on the south face of Mount Iwaki, on national forest land it leases. The advanced course has mogul and deep-snow sections. Konan Bus services from Hirosaki Station reach the Hyakuzawa Onsen-mae stop in about 50 minutes. Sources: rinya.maff.go.jp, hyakuzawa-ski.com, city.hirosaki.aomori.jp, hirosaki-kanko.or.jp (sources read 12 Oct 2026; an AI draft the site operator has not yet checked)
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 19% of the vertical on the runs descends to the north or east. The most common direction is south (81%).

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.
