Kaminaka Onsen is a thermal facility in Mihama town in Fukui Prefecture on the Sea of Japan coast, situated in the Wakasa Bay area — a scenic arc of pine-clad peninsulas, small islands, and fishing villages historically known as the kitchen of the imperial court for the seafood supplied overland to the ancient capitals of Nara and Kyoto. The siliceous hot spring waters of Kaminaka emerge from the geological basement of the Obama-Mihama area, providing therapeutic bathing in a coastal setting famous for crab fishing, the pristine beaches of Wakasa Bay, and proximity to the ancient Buddhist pilgrim routes to Mount Hiei and Kyoto. The combination of siliceous onsen bathing, exceptional fresh seafood from the Sea of Japan, and the culturally rich maritime heritage of the Wakasa region makes Kaminaka Onsen a distinctly Fukui coastal thermal experience.
