A bouna sauna with auto-löyly and a scenic outdoor bath lined with massive rocks
Niigata Shibata City
"Natural Hot Spring Shiun no Sato" is a day-use hot spring facility located in Shiunjikinen Park in Shibata City. The source water springs from 1,300m underground and is an extremely saline sodium-chloride strong brine hot spring, known for its excellent heat-retention effect and loved as a "hot bath." In 2022, the sauna room was completely renovated, and a Metos-made bouna sauna equipped with auto-löyly that runs every 12 minutes was introduced. The powerful waves of heat, rich in humidity, have earned strong support from sauna enthusiasts as well. At the facility's signature custom outdoor bath, carved out of a massive rock, you can enjoy an exceptionally open-air bathing experience while feeling a pleasant sea breeze.
