We've mustered a great deal of audacity to list this gorgeous, oozing-with-mountain-culture lodge in our list of Hokkaido huts. It's not a hut. Open from May till October, it's a watering hole and oasis for local guides, national park track maintenance volunteers, hikers, mountaineers, skiers, and even the odd out-of-place lost tourist. It has an onsen hotspring. You can hang wet gear on the banisters yet still walk around the lodge in the supplied yukata gown. There's a small common-area alcove with a piano and open fire. For anyone who truly loves the mountains, this lodge is home.

This gorgeous lodge 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 lodge is accessed via a paved road from Kamikawa Town.

General notes

According to the lodge’s website, the first time a building was built on the site was in 1926, first named Naoi Onsen (直井温泉). Since the adjacent hut and the lodge itself was built, and has changed management multiple times. Currently, Aizankei Onsen Eco Lodge is managed by Rinyu Kanko – the company that runs the Kurodake Ropeway. Despite all the changes over the years, the atmosphere stays the same – a magnet for mountain people. The ‘eco’ moniker hails from the fact the lodge’s electricity is generated by the lodge’s own hydro electric generator.

It’s most certainly not a hut. It’s a fully serviced lodge with clean Japanese-style guest rooms, onsen hotsprings, a kitchen and self-catering area, a piano, and an open fire. The best part of the lodge is the people. The current (as of 2020) manager was one of the founders of a popular Sapporo mountain gear shop (Paddle Club), and the lodge is a common port of call for mountain guides and track maintenance staff. If you’re staying there, sit in the open-fire common area, strike up conversations with other guests, and play the piano.

The lodge is open from May till October. It’s closed over winter – the 13km approach road is not cleared in winter.
