"Shimizu no Yu Hidakagawa Onsen" is a day-use hot spring facility in Hagiwara, Gero City. Its biggest draw is its strongly alkaline simple hot spring, with a pH above 9. The colorless, clear water has a faint sulfur scent, and the moment it touches your skin, it feels remarkably smooth, letting you experience its reputation as a beauty-enhancing bath firsthand. In the sauna, a steady heat gently fills the room. The cold plunge bath is thoroughly chilled, and with its perfect layout right in front of the sauna room, you can enjoy alternating hot and cold bathing to your heart's content.
