Lukewarm BathAbout
Kurhaus Yunoyama is a city-run day-use spa built around more than ten named onsen bathing styles in a swimsuit-required zone, among them jet baths, a misting sauna, a box steam bath, a falling-water utaseyu, a cooler nuruyu soak, and an open-air rotenburo. A separate plain bathing area (no swimsuit) has its own dry sauna, and next door an indoor pool is filled with the same hot-spring water, water slide included. The spring, Yunoyama Onsen, was once a toji retreat for the Asano lords who ruled Hiroshima domain, and is one of only 21 hot springs nationally designated for its health-giving water. The complex sits in a quiet, hilly stretch of Saeki Ward, the building is showing its age, and the mood is closer to a community pool than a resort: busy with families through the day, and older regulars settled in for long weekday soaks.
