ハネサウナ / Hane Sauna

Hane Sauna sits in Toyosato, a quiet corner of the Nozawa Onsen hot spring village in Nagano. It's classified as a bathhouse built around its sauna, run on a day-pass basis rather than as a hotel amenity, which makes it an easy stop for visitors staying elsewhere in town.

The schedule is organized into three sessions a day — morning (9:00–11:30), early afternoon (12:00–14:30) and late afternoon (15:00–17:30) — on Monday, Friday, Saturday and Sunday. It's closed Tuesday through Thursday. The slotted structure suggests limited space or a reservation-friendly setup, so calling ahead is worth doing before a visit.

Pricing falls in the budget tier among spas on this guide, and the place is marked as family friendly, meaning it's set up to welcome a range of ages rather than being an adults-only sauna circuit. Beyond that, there's no posted list of treatments, towel policy, or locker details, so first-time visitors should confirm specifics by phone or through the venue's Instagram account before arriving.

There's no official website — the main point of contact is a phone number and an Instagram page, which is typical for small, locally run sauna spots in onsen towns like this one. If a dedicated sauna session with a straightforward, no-frills setup is what you're after during a Nozawa Onsen trip, this is a small, specific option to check rather than a full-service spa with a long treatment menu.
