JOKIJOKI Sauna Opens in Hakuba: Finnish-Style Private Outdoor Sauna

TL;DR: JOKIJOKI lodge in Hakuba opened a private Finnish outdoor sauna on July 1, 2026, available only to overnight guests.

Harapeko-gumi LLC, the operator behind JOKIJOKI—a Nordic-style vacation rental in Hakuba—announced on July 24 that their new Finnish-style outdoor sauna, JOKIJOKI Sauna, is now complete and accepting reservations. The facility opened July 1, 2026. It's private: only guests staying at the JOKIJOKI lodge can use it, and they can book it anytime during their stay for as long as they want.

The company's representative, Yu Asai, visited Finland and toured 12 sauna facilities before designing this one. The result is a replica Finnish sauna hut painted in traditional Falun Red, sitting in the middle of Hakuba's alpine landscape. Inside: a Narvi wood-burning stove (Finland's top-selling brand), local Itoigawa cedar walls, a round porthole window in the door, and space for self-löyly (pouring water on hot stones). Outside: Northern Alps views, clean mountain air, and cold-plunge water sourced from snowmelt.

The company is also running a crowdfunding campaign on CAMPFIRE to support the sauna build, with pledges open until July 31, 2026.

What This Means for International Visitors and Buyers

This is one more signal that Hakuba's summer product is maturing. A decade ago you came here to ski and maybe hike in July. Now you're seeing lodges add premium summer-season amenities—saunas, yoga platforms, extended gondola hours—to justify higher shoulder-season rates and occupancy.

For property investors, it's worth watching how these add-ons perform. A private sauna is expensive to build and maintain (firewood, cleaning, liability). If JOKIJOKI can fill midweek summer bookings at a premium because of it, that's a proof point. If the novelty fades after one season, it's a cautionary tale. I'd keep an eye on their booking calendar and whether other lodges follow suit.

For visitors: JOKIJOKI is a whole-building rental, so this isn't a drop-in public sauna. You'd need to book the entire lodge (sleeps ~8–10 based on similar properties in the area, though the PR release doesn't specify). If you're planning a group trip and you want a proper Finnish sauna experience without driving to Nozawa Onsen, this is now an option. Just confirm capacity and rates directly—I haven't seen pricing published yet.

Background

Hakuba has always had onsen (hot springs), but dedicated saunas are newer. A few scattered private lodges have added barrel saunas or electric units in recent years, but purpose-built Finnish-style huts are still rare here. Nozawa Onsen, 40 minutes north, has a stronger sauna culture and public facilities, so Hakuba operators are playing catch-up.

JOKIJOKI's crowdfunding campaign suggests the build wasn't cheap. I haven't seen the final funding total, but the fact they're soliciting pledges until July 31 means they either needed the capital or wanted early adopters locked in. Either way, it tells you this is a bet on sustained summer demand, not a side project.
