Tsubaki Onsen in Tanabe city, Wakayama Prefecture, flows from siliceous springs near the mouth of the Kumano River in one of Japan's most sacred landscapes, the Kumano Kodo pilgrimage network, a UNESCO World Heritage Site whose ancient mountain trails have been walked by emperors, retired emperors, and millions of ordinary pilgrims since the Heian period seeking the three great shrines of Kumano deep in the forested mountains of the Kii Peninsula. The silica-rich spring water is celebrated for its exceptionally smooth, skin-beautifying quality, providing a deeply restorative soak after the physical demands of walking the ancient forest trails that descend to Tanabe from the sacred mountain shrines. Bathing in Tsubaki's mineral waters at the end of a Kumano pilgrimage stage connects thermal wellness to one of Japan's most profound and enduring spiritual traditions.
