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): 5 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
Muroran City pitches this hill as a place for beginners to practise, and it runs night skiing. According to the Hokkaido Shimbun, the city plans to close it at the end of fiscal 2026 and replace it with a new snow-play park inside Muroran-dake Sanroku Park, known locally as Danpara Park.

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 2% of the vertical on the runs descends to the north or east. The most common direction is south (98%).
Source: OpenSkiMap (© OpenStreetMap contributors, ODbL 1.0). How finely ski areas are drawn varies by region, so treat the counts as indicative. Vertical is the difference between the highest and lowest points of the mapped runs and lifts.
This ski area does not put a camera on its own slopes. The nearest live view is the road below.
Footage remains the copyright of each operator. JAPANSNOWLINE neither stores nor redistributes it.
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.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Sanlaiva | 14.0 km | 163 cm | 1503 |
| Orofure Ski Area | 15.0 km | 157 cm | 1578 |
| Rusutsu Resort | 34.0 km | 212 cm | 1041 |
| Nakayama-toge Ski Resort | 49.0 km | 264 cm | 655 |
The most snow falls in January. March brings 95% 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 37 cm, less than the median of 46 cm.
Across the 12 winters measured, the average is 135 cm, and 6 of them fell short of it. The leanest was 2018/19 with 90 cm; the biggest was 2017/18 with 175 cm (1.9 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.
Total snowfall from December to March recorded at the 登別 weather station — 10.4 km from this ski area, 232 m below its mid-slope.
| Three-season average | 375 cm |
| 2023/24 | 374 cm |
| 2024/25 | 431 cm |
| 2025/26 | 319 cm |
The figure calculated on this page is 141 cm.
A weather station is not a ski slope. We picked one at a similar elevation, but it stands in a valley or a village. More snow falls on the mountain above it. We have not tried to guess how much more.

2 hot spring sources with published analyses lie within 5 km of this ski area, nearest first (the hottest is 33.3 °C).
| Source | Distance | Temperature | pH | Type |

| 室蘭山口温泉 | 4.5 km | 26.2℃ lukewarm | 8.9 alkaline | alkaline simple |
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.
