At Ibusuki, on the southern tip of Kyushu, geothermal water heats the sand of the shoreline. Bathers lie in a shallow trench on the beach and attendants shovel hot sand over them — a practice documented here for around three centuries. Saraku is the municipal facility on the seafront.

Pourquoi y aller
Sunamushi onsen is unique to a handful of places on earth, and Ibusuki is its home. Fifteen minutes buried in heavy, radiating sand feels nothing like a hot pool, and the setting — open sea and volcanic ridge — is remarkable.
