Jet BathAbout
This is a sizeable day-use bathing complex in the forested hills of Kutsuki, with an indoor bath behind a wide window, an open-air bath facing the mountains, a sauna and a cold plunge. On weekends and holidays two more baths open in the afternoon. The water is a simple alkaline spring, soft and smooth on the skin. Baths are separated by gender, and the complex also has a restaurant and a snack counter, so it works as a half-day stop rather than a quick soak.
