24-hour hot spring baths for your own private use.

A Timeless Hot Spring, All to Yourself.

Nestled at the foot of the Northern Japan Alps in Azumino, this exclusive whole-house villa offers an extraordinary retreat surrounded by pristine nature and fed by the legendary Nakabusa hot spring, a source that has flowed continuously for over a thousand years.

Private Onsen The villa features a private bath crafted entirely from Japanese cypress (hinoki), filled with free-flowing natural sulfur spring water directly from the source. Known for its exceptional quality, the mineral-rich water warms you to the core and leaves your skin silky smooth. As this is your own private space, you are free to enjoy the bath whenever you wish, for as long as you like.

Authentic Sauna & Cold Plunge A full-scale sauna with natural stone walls allows you to warm deeply at your own pace, with adjustable temperature and löyly (steam) to enjoy. After your session, refresh in the outdoor cold plunge bath, fed by Azumino's pure natural spring water, and take in the views of the Northern Alps during your cool-down. The contrast between heat and cold brings a deeply restorative sense of calm and balance.

Immersed in Nature Wake to the sound of birdsong in the morning. Gaze up at a sky full of stars at night. Surrounded by the beauty of Azumino's countryside, this whole-house villa gives you the freedom to relax at your own pace, with complete privacy and no interruptions.

Tattoo-Friendly As a private whole-house rental, guests with tattoos are welcome to use all facilities with complete comfort and peace of mind.

Azumino Udon On-Site Our villa shares its grounds with Azumino Udon, a local specialty restaurant where you can enjoy handcrafted udon noodles made with Azumino's pure water and premium dashi broth.
