Hayama Onsen is a coastal hot spring in the elegant seaside town of Hayama in Kanagawa Prefecture, historically known as the location of the Imperial Villa and as one of the most exclusive residential addresses on the shores of Sagami Bay. The chloride-rich mineral waters provide skin-nourishing and body-warming benefits suited to the breezy maritime climate of the Miura Peninsula, complementing the town's reputation as a haven for sailing, art, and refined coastal living. Views across Sagami Bay toward the iconic silhouette of Mount Fuji on clear days make bathing at Hayama Onsen an experience of extraordinary scenic beauty on Tokyo's southern doorstep.
