Tochigi Onsen Yuraku no Sato is located in Tochigi City, Tochigi Prefecture, Japan. Its iron-rich, mildly acidic water emerges at around 38°C and supplies an indoor bath, an outdoor bath and a sauna.
Insider tip — Yuraku no Sato in Tochigi City taps into ferruginous deep waters in the Kanto plain's northern reaches, offering amber-tinted baths prized for their circulatory benefits. The iron-rich spring earns its place as a local wellness institution for residents of this historic castle town south of Nikko. A soak here pairs naturally with exploring Tochigi's well-preserved Edo-period merchant quarter along the Uzuma River.
