Ashikaga Kashimaen Onsen, in Ashikaga, Tochigi Prefecture, warms sodium-chloride water to 41°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Kashimaen Onsen serves Ashikaga City in the Watarase River valley of Tochigi, home of the Ashikaga Gakko — Japan oldest educational institution, established in the Nara period and documented by Francis Xavier in 1549 as one of Japan most important academic centers. Ashikaga is also famous for the Ashikaga Flower Park wisteria garden where 350-year-old wisteria vines create one of the world most spectacular floral tunnel displays each April and May — the violet and white cascades photographed by visitors from across the world that have made this garden internationally celebrated.
