Ashikaga, in the southern Tochigi Prefecture along the Watarase River, is home to the Ashikaga School — Japan's oldest academic institution founded in the ninth century whose extraordinary library of Chinese Confucian texts attracted scholars from across East Asia and was described by Jesuit missionary Francis Xavier as the greatest academy in all of eastern Japan. Ashikaga Onsen Tochigi draws on sodium and bicarbonate thermal waters from the geothermal resources of the southern Tochigi zone, offering restorative baths in a city of exceptional historical depth whose Ashikaga School legacy, traditional textile heritage connecting to Kiryu silk culture across the Watarase River, and famous Ashikaga Flower Park wisteria displays create an outstanding destination for thermal visitors. The Ashikaga Flower Park's legendary Great Wisteria Tree — one of Japan's most magnificent flowering trees whose purple cascades attract visitors from across the country each May — the reconstructed Ashikaga School buildings, and the traditional Banshu-ori textile weaving culture create a deeply layered and visually spectacular spa destination in southern Tochigi Prefecture.

Insider tip — Ashikaga, home to one of Japan's oldest academies and a spectacular wisteria garden, also offers a bicarbonate spring drawn from the Watarase River basin geology. The smooth, slightly alkaline water complements a cultural day trip perfectly. Visit during the famous wisteria season in late April to combine purple-draped pergolas with a relaxing evening soak.
