"Kenko-yu Kukan Iwata Nanatsuboshi" is one of the largest super sento facilities in the Iwata area of Shizuoka Prefecture. Its biggest pride is the three carbonated baths, each with a different temperature and atmosphere. High-concentration carbon dioxide gently envelops the body, promotes blood circulation, and helps relieve daily fatigue from the roots. The sauna area is also extremely powerful, with a high-temperature dry sauna that drives vigorous sweating with overwhelming heat. It pairs perfectly with the crisp, cold cold plunge bath and the well-equipped outdoor air bath area. Together with a wide variety of artificial hot spring baths, it is a place where you can recharge your health and vitality.
