A large public bath that offers two types of bath, an open-air rock bath and a stone bath, both finished with Yamaguchi-grown cypress for the pillars, walls, and ceiling, and alternated monthly between men and women. The alkaline simple spring, with a pH of 8.6, is fed as free-flowing water that is heated from a source temperature of 34.6°C, and is known for its skin-smoothing beautifying effects as well as benefits for neuralgia, muscle pain, and joint pain. In a space wrapped in the scent of cypress, you can slowly surrender yourself to spring water that preserves the freshness of the source.

An open, inviting open-air bath set in a roofed outdoor space. You can bathe while enjoying the greenery of the mountains and the songs of small birds, with the unhurried pace unique to a rural area. It is installed in each of the baths that alternate monthly between men and women, and the seamless flow from the indoor cypress bath to the pleasant outdoor air is especially enjoyable.
