Hatcho Onsen

Hatcho Onsen is a small and venerable mountain hot spring in Kamikatsu town in Tokushima Prefecture on Shikoku Island, a remote community famous as Japan's first zero-waste town committed to sorting all refuse into 45 categories for complete recycling — and Hatcho Onsen reflects this spirit of traditional, respectful simplicity in its unpretentious siliceous thermal bathing facilities. The siliceous spring waters emerge from the ancient schist and granite geology of the Shikoku Mountains, offering a pure and lightly mineralized soaking experience enjoyed by local residents and pilgrims on the Shikoku 88-temple Henro pilgrimage route for generations. The combination of traditional onsen culture, the extraordinary zero-waste community philosophy of Kamikatsu, and the deeply spiritual character of Shikoku pilgrimage culture makes Hatcho Onsen a destination where the act of bathing carries unusual ethical and philosophical resonance.
