Bath & Sauna
Blue Star's private sauna and bath offers a brand-new Harvia sauna and cold plunge, alongside a separate hot bath room — each exclusively yours.
The water is filtered snowmelt.
The access is private.
What you'll find inside is something Hakuba has been missing: a dedicated space to properly recover, unwind, and reset — away from the noise of the resort and the crowds of the public bathhouse. The only thing left to do is show up.
Private sauna and bath are available by advance reservation and require an additional fee separate from the room rate. Please contact the front desk for details.

The Hot-Cold Ritual
Alternating between sauna heat and a cold plunge is a proven recovery method. Heat relaxes muscles and boosts circulation, while cold reduces inflammation and helps flush fatigue from the body. This Nordic practice speeds recovery and delivers a powerful endorphin lift after long days on the mountain.
The Hakuba Advantage
Set in Tsugaike, just one minute from the ski slope, Blue Star's sauna and bath are designed for immediate mountain recovery. Whether skiing or hiking, you soak in filtered snowmelt sourced from Hakuba's peaks—naturally soft, mineral-clean, a world away from a city tap. You're not just recovering in the mountains. You're recovering with them.
Private, By Booking Only
The sauna, cold plunge, and hot bath are all available exclusively by private booking. Each session gives you complete solitude, making it an ideal onsen alternative without crowds. It's a rare combination of privacy, pure mountain water, and full control over your experience.
Year-Round Recovery in Hakuba Valley
Hakuba Valley is famed for deep winter snow and dramatic summer alpine scenery. Tsugaike Kogen offers long ski runs in winter and panoramic hiking in summer, and Blue Star's private sauna and bath complements both. It's a warm refuge in freezing months and a restorative retreat after long summer days outdoors.
