Shimizu Onsen

Sodium hydrogen carbonate spring with naturally alkaline water that is gentle enough to leave skin feeling smooth. A bathing facility wasn't built here until the 1980s, when a public foundation created it to revitalize a community that had lost most of its population since the 1960s. A new facility opened in 2024 with a mist sauna and a cypress relaxation lounge, built largely by local craftspeople using timber from Aridagawa. Its most distinctive feature is a cold water bath (mizuburo) filled with undiluted spring water that naturally flows between 17 and 23 degrees, preserving its mineral content without any dilution.
