Teradomari Onsen

Three distinct hot spring facilities serve the seaside town of Teradomari, each drawing from different sources and offering different bathing experiences. Sumiyoshi-ya, a historic inn tracing its history to the late seventeenth century, has outdoor cypress-wood baths fed by both a sodium-hydrogen carbonate spring and a cool chloride spring, with views across Teradomari Port toward the Sea of Japan. It also manages a private Finnish-style sauna available by reservation. Hokushinkan, a small nine-room mountain inn, offers access to both a brownish-red sodium chloride spring and an unusual cold-mineral spring at 14 degrees Celsius. Hotel Asuka, closest to the shore, has rotating bathing areas where on clear days Sado Island is visible in the distance.
