Aizankei Onsen Hut (愛山渓温泉ヒュッテ) is a quaint old hut standing right next to a more modern mountain lodge at the foot of Aibetsu-dake (愛別岳, 2119m) in the northern reaches of the Daisetsuzan National Park. Officially, it's the 'dormitory' wing of the eco-lodge next door, but the hut can be used year round. The road to get to the hut is about 20km long, winding its way up to 1000m in altitude. While it's possible to drive to the hut during the open season (May till October), there's no mobile reception at the hut - a great place to get away from it all. Hut users can use the natural onsen hotspring in the adjacent lodge during the summer open season (not in winter).

Aizankei Onsen Hut is located here, on the northwestern flanks of Aibetsu-dake (愛別岳, 2113m) in the northern reaches of the Daisetsuzan Range in central Hokkaido. The hut is accessed via a paved road from Kamikawa Town.

General notes

Aizankei Onsen Hut is a very well serviced hut. It’s one of the very few commercial huts in Hokkaido, with a fully-featured mountain lodge just next door, operated by the same company. Incidentally the hut is owned and operated by the same company that operates the Kurodake Ropeway in Sounkyo (Rinyu Kanko). There’s an onsen at the adjacent lodge, free to use for people staying at the hut (during the summer season). The hut is also open for use during the winter as an emergency hut, but the access road to the hut (and adjacent lodge) is closed from October till May – it’s a long 13km walk from the end of the snow-clearing to the hut. In addition to the facilities listed below, there’s also a clothes washing machine available for use in the lodge (free of charge).

Sleeps 40 people.

The hut is huge, so it’s unlikely that the hut will be booked out – you should be able to arrive and stay. Just in case, however, we’d recommend booking ahead if your itinerary is arranged in advance.

Hut Fees

3,000yen for overnight stays. This includes access to the onsen in the adjacent lodge. Winter use of the hut is free.


Heating: The hut is well heated via large kerosene heaters on both floors of the hut. There is no heating available in winter.

Water: There’s running water in the hut during the normal summer operating season (May till October). There’s no running water during winter.

Kitchen/cooking: There’s a basic kitchen with a few plates and cups, as well as a few pots and pans. No cooking facilities are provided, so you’ll need to bring your own cooker.

Bedding: No bedding is provided.

Elecricity: There’s electricity in the hut during the operating season (no electricity in winter). The electricity is generated on site using the lodge’s own hydro-electric generator, run by a river nearby.

Toilets: There are no toilets in the hut, but during the open season, hut users can use the public toilets outside the hut, or use the toilets in the lodge. During winter, the public toilets will be buried in snow, so it’s best to assume there are no toilets available in winter.

Cell reception: There’s no mobile reception at the hut (or lodge).


There’s no hutkeeper in the hut itself, but there’s staff at the lodge next door during the summer open season. There’s no staff present in winter.

Special Aizankei Onsen  Hut Notes

While this is a commercially run hut, the age-old adage still applies: Always leave a hut cleaner than you found it. There’s also a more fully-featured Eco Lodge about 20m away from the hut (see the details here).

  1. Hi, Where can i find if the huts are open or not, depends of the season please ?
    thanks for all your work 🙂

    1. Best place to start is each hut’s description on Hokkaido Wilds: Other than that, you’d need to visit the hut’s official webpage (if one exists) to see if they have any updated information regarding opening times. At this point (April 5th 2024), the only information we have about the Aizankei Onsen Hut is that for the 2024 summer season, it will open some time at the end of May 2024.
