Tennogawa Toron Onsen is located in Fukushima City, capital of Fukushima Prefecture, in northeastern Japan. The sodium-chloride water reaches 41°C, pH 7.3. The facility offers an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Tennogawa Toron Onsen draws sodium-chloride water in the Fukushima basin, where deep borehole springs have long supplied neighborhood bathhouses serving the agricultural communities of the Aizu foothills. The clean, slightly saline water provides efficient warming during Fukushima's cold winters and a refreshing mineral rinse in summer. The name 'toron' references the traditional Japanese concept of soaking long and slowly to absorb the full benefit of thermal mineral water. The facility's central location makes it easy to combine with visits to Fukushima's renowned sake breweries in the surrounding city.
