Self-Gushing Carbonated Spring

Said to date back to the Heian period and linked to the monk Gyoki, this sacred spring once welcomed pilgrims bound for Kumano. Its natural flow ceased for centuries until a 1965 boring struck water at 501 m, and today its calcium- and magnesium-rich water builds thick mineral crusts around every bath.
