Sennin Buro is located in Kumano city in the southern portion of Mie Prefecture on the Kii Peninsula, where chloride-rich thermal waters emerge in a landscape shaped by the ancient Kumano pilgrimage traditions that drew emperors, nobles, and common pilgrims along the World Heritage Kumano Kodo routes to the Kumano Grand Shrines for over a thousand years. The sodium-chloride mineral composition of Sennin Buro's thermal waters carries properties valued for warming the body, conditioning the skin, and supporting the musculoskeletal recovery of those who have walked the mountain pilgrimage routes through the dense primeval forests of the Kii Peninsula. The name Sennin Buro—meaning 'thousand-person bath'—evokes the ancient tradition of communal thermal bathing in the Kumano area, where the proximity of the sacred pilgrimage routes to natural hot springs created a landscape where physical cleansing and spiritual purification were inseparable elements of the pilgrim experience on Japan's southern sacred peninsula.
