Best season

Mt. Asahi (旭岳 - 2,291m), Hokkaido's highest mountain, is an active volcano. In winter when the weather isn't blowing a gale, it is possible to wander relatively freely around the fumaroles, at around 1,700m. The route outlined here starts at the top of the Asahidake Ropeway, but if you'd rather skin up, just follow the Asahidake downhill ski course B, marked on the descent of the route on this page - it will take about 1.5 hours or so. Don't take the mountain lightly, as the weather can change very quickly. If you're lucky, however, the grand old Mt. Asahi can turn on some incredible weather.

Route Map

Need to know details

Location

This route starts at the Sugatami Station at the top of the Asahidake Ropeway (here).

General notes

This route is a very leisurely wander around the fumarole areas near the top of the Asahidake Ropeway. If the weather is good, consider boot-packing up to the top of Mt. Asahi as well, although this will add a solid 5 hours to the trip time. It is also a very hard-packed, icy route, so consider carrying crampons and hiring a guide. Overall, avalanche and exposure risk can increase exponentially in this area if the weather turns. Do not take this ‘easy’ route lightly – people have and do regularly die here.

Hut

None

Route markers

There are no route markers. People can happily get completely and hopelessly lost even a few hundred meters from the ropeway top station if the weather turns, so only venture out in good visibility conditions with a good forecast.

Route Timing

Up | 1hrs
Down | .5hrs

Set aside about an hour for wandering around the fumaroles, and then about 30 minutes for skiing down the Asahidake ski area.

Transport

Public transport:

The Asahidake Ropeway is accessible by public bus. Four buses per day leave Asahikawa JR Station bound for the ropeway (http://www.asahikawa-denkikidou.jp/kyouei/66%20time(2016.10.1).pdf).

By car: 

There is ample parking at the base of the Asahidake Ropeway (here).

Snow and route safety

When the weather is nice, or even only slightly nice, it can be very easy to be complacent on this route. This is probably because of the sheer accessibility of the area via the ropeway. You’ll likely see tourists in sneakers and jeans bracing against the cold for a quick selfie near the ropeway station. The reality is that the top of the ropeway is at 1,600m, which is well within serious mountaineering territory. In winter, with windchill, it can easily get down to below -20degC. Even with no snow forecast, high winds will cause whiteout conditions very quickly. Make conservative decisions in the high mountains of Hokkaido. If you’re lucky enough to get lost and then rescued (and not die), personnel and rescue costs are steep, and will be charged directly to you; think in the tens of thousands of dollars if it takes more than a few hours to find you.

Route Trip Notes

We were on a week-long holiday on the eastern side of Hokkaido, and naturally had to drive all the way back to Sapporo, so why not go via Asahidake Onsen? The days before Mt. Asahi included an overnight hut trip ski tour on Mt. Mokoto near Lake Kussharo. We had amazing weather on the second day there (trip report and route guide here), so we were hoping for more of the same on Hokkaido’s rather unpredictable highest mountain.

We stayed in Asahidake Onsen village (resort?) at the Shirakabaso Youth Hostel (the cheapest but slightly overpriced accommodation in town), and woke to clear skies. A quick look at Mt. Asahi from the youth hostel viewing platform, however, suggested that conditions at the top of the Asahidake Ropeway were not going to be great. It looked to be blowing a gale.

We decided to head up the ropeway anyway, if it was running; it closes if the wind is too strong. It was only a 10 minute walk from the hostel to the ropeway, so we skinned most of the way up the side of the road. We were taken aback at how much snow there was in comparison to on the other side of the ranges out further east.

At the top of the ropeway, it was quite clear that it was not going to be a leisurely meander. It was a near-whiteout with scathingly cold and strong wind. We made it about a quarter of the way towards the stone hut with about 100m visibility, before turning back when this dropped to about 20m.

We were booked in for another night in Asahidake Onsen, so we returned down the ski slopes to the village, hoping for better weather the next day.

The next day broke to near-perfect conditions. We wasted no time getting going and were on the first gondola up the mountain.

When you can stop, hold your breath, and hear nothing but loud silence, you know you’ve hit the weather jackpot. Other climbers with more time on their hands were marching up the southern ridge of Mt. Asahi, heading for the summit. We left this for another time, and concentrated on the much more leisurely circuit around some of the steam vents in the ‘Hell valley’.

I was infinitely jealous of whoever had spent the night out in a tent near the stone emergency hut. It would have been a blustery start to the night, but I can imagine the morning calm would have been worth it.

The stone hut (asahidake ishimuro) is well-and-truly an emergency hut, with no non-emergency overnight stays allowed. Even if you wanted to stay overnight in winter, it would be nearly breaking and entering, as the second-story window is well iced shut. A screw-driver on a multi-tool would probably shimmy it open, but not without damaging the wooden framing.

We carried on up the valley to a truly majestic landscape.

After pottering around at the upper-most fumaroles, we made our way back down to where the summer walking trail does a loop back to the ropeway station. Heading back down the valley gave us a great view of the sea of clouds further down the Asahikawa plains, and on to the Yubari mountain range in the far distance.

Once we were back at the ropeway top station, we joined the throngs of new arrivals for a fast blast down the unique groomed slopes of the Asahidake Ropeway ski area. This ski area is unique in that 1) the scenery is amazing (great massive pines covered in marshmallow snow) and 2) it is not really much of a ski area – the groomers are only just wide enough for some short turns and are more like access-road shortcuts down the mountain. An absolute blast!

All in all a great first-visit to the beautiful but cantankerous Mt. Asahi, Hokkaido’s highest.
