Shakunage Spa in Azumino

Shakunage Spa is a day-use onsen facility in the Hotaka Onsen area of Azumino featuring multiple temperature-controlled baths supplied with mineral-rich water from local geothermal sources. The facility offers both indoor and outdoor bathing options with full amenities for day visitors.

The modern wellness facility opened in October 2016, expanding the thermal facilities network in Azumino region of Nagano Prefecture. The facility builds on longstanding traditions of bathing in this volcanically active area.

The facility maintains Japanese bathing traditions through separate sections for men and women, where visitors follow specific cleaning rituals before entering the baths. These practices reflect cultural values that emphasize respect and order in the bathing experience.

The facility is easy to locate and provides areas designed for full-day visits with lockers and changing rooms in both indoor and outdoor sections. It is advisable to bring a towel or acquire one on-site, as the facility is organized for day visitors.

The water contains distinct mineral compositions emerging from geological formations within the Pacific Ring of Fire, giving the baths unique geochemical qualities. Visitors often notice different effects depending on which bath they choose.
