A blended simple thermal spring: the certificate names Beppu City's Unsenji source and others, with the sample drawn at the outlet of the storage tank where they are pooled. Neutral and hypotonic, it carries only 764 mg/kg of dissolved solids, so the water itself is light and undemanding on the body. What lifts it is silica — 159 mg/kg of metasilicic acid puts it squarely in Japan's beauty-water family, leaving the kind of thin mineral film that makes skin feel noticeably smoother afterwards.

107. Kamiharu Onsen, Beppu ★ An old-school onsen for ¥200. The stated hours are 06:00 to 12:00 and 14:00 to 22:00. There is a hidden private bath. They stamp the Beppu onsen-do. No staff, no shower. The bath photo from the internet matches. The water is clear, and the temperature is 46.5. It is easy to breathe inside. Next to the bath there is an entrance to an empty room. It stands out for its unclear room, secret private bath, and high temperature. 01.05.2024 28.12.2025
