Nakago Onsen (Toryanse) is located in Kitaibaraki, Ibaraki Prefecture, on Japan's Pacific coast. Its sodium-chloride water flows at 41°C, pH 7.3. The site combines an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Toryanse, named for the beloved traditional Japanese children's song about passing through a gate, sits in Kitaibaraki City where the Pacific coast meets the forested foothills of the Abukuma Highlands at the Fukushima border. Kitaibaraki rebuilt its coastal fishing communities after the 2011 Great East Japan Earthquake tsunami, and the area is also celebrated for the Isohara coastal rock formations.
