Kanagawa Atsugi City
A dome-shaped automatic löyly sauna and a 100% natural groundwater cold plunge bath in perfect harmony
"Natural Hot Spring Yukaraku Atsugi" is a day-use hot spring facility in Atsugi, Kanagawa Prefecture, distinguished by its strong focus on sauna and cold plunge bath experiences. In the open-air area, it features a rare dome-shaped Finnish sauna, where you can bask head to toe in enveloping heat and steam from the automatic löyly. Its biggest draw is the 100% natural groundwater cold plunge bath, drawn up and used as free-flowing water without going through a chiller or filtration. With a stable water temperature of around 18°C throughout the year, and the smooth feel unique to groundwater, it gently yet refreshingly cools and tightens the body after sauna use. The facility also offers a wide range of bathing experiences, including a natural simple hot spring, a high-concentration carbonated spring, and a barley stone mist sauna you can enjoy while lying down.
A natural simple hot spring that is gentle on the skin. You can fully enjoy its rich benefits in baths such as the open-air bath, cypress bath, and combination baths with a high-concentration carbonated spring. The mild, unobtrusive water soothes everyday fatigue over time, and after bathing, a pleasant warmth lingers in both body and mind.
A rare dome-shaped sauna room located in the open-air area. Frequent automatic löyly every hour at 00, 20, and 40 minutes keeps the room filled with pleasant humidity and heat at all times. The dome shape helps the steam circulate especially well, creating a sweating experience that gently yet powerfully envelops the entire body.
