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): 17 cm, 152% 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
The ASHIMOI KANKO in the name belongs to Ashimoi Kanko Bus, the company that bought the naming rights offered by the town. A new lift and lodge were built for the reopening in the winter of 2022. Sources: town.numata.hokkaido.jp (sources read 12 Oct 2026; an AI draft the site operator has not yet checked)
Weather models read low in the mountains: a Japan Meteorological Agency station 3 km away measured 755 cm a winter over the last three seasons, against 256 cm from the model.
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 south (86%).

This ski area does not put a camera on its own slopes. The nearest live view is the road below.

Asahikawa webcams & snow report — all 10 ski areas →
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 |
|---|---|---|---|
| Kamui Ski Links | 23.0 km | 206 cm | 1092 |
| Kokusetsu Horotachi Ski Area | 26.0 km | 250 cm | 734 |
| Santa present park | 28.0 km | 200 cm | 1149 |
| Inosawa Sky Slopes | 31.0 km | 200 cm | 1149 |
| Boyodai Ski Area | 32.0 km | 290 cm | 521 |

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 37 cm, less than the median of 46 cm.
Across the 12 winters measured, the average is 225 cm, and 6 of them fell short of it. The leanest was 2016/17 with 163 cm; the biggest was 2017/18 with 299 cm (1.8 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 石狩沼田 weather station — 3 km from this ski area, 30 m below its mid-slope.
| Three-season average | 755 cm |
| 2023/24 | 798 cm |
| 2024/25 | 808 cm |
| 2025/26 | 658 cm |
The figure calculated on this page is 256 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.

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.
