Hot Springs

Natural hot springs that unwind your body and mind

The natural hot spring water piped from Kuronagi, a hidden region of the Kurobe Gorge, is beneficial to your health and beauty. The water relieves neuralgia, muscular pain, and chronic digestive problems, as well as rejuvenating your skin. Enjoy this healing hot spring water in the main baths made of beautiful sakura red granite or in the rustic outdoor bath.

Mainbath: Mizubasho and Shakunage

Enjoy a time of relaxation in the spacious bathing area with elegant bathing pools made of sakura red granite, while overlooking the beautiful scenery of the season. The bathing area has a sauna to refresh your body and mind, as well as a bathing pool with ultrasonic waves that gently massage your body.

The main baths are available 24 hours each day.
(Please note that the sauna will be closed between 11 p.m. and 8 a.m.)

Outdoor bath: Kappa-no-Yu

Kappa-no-Yu allows you to immerse yourself in natural hot spring water in the enriched atmosphere of the nature of Unazuki. In both the male and female bathing areas there are sit statues of Kappa (mythical creatures). Legend has it that if you wash the plates on their heads with the hot spring water, they will grant you a wish in return.
