Bathing indications
The facility and the Gozu hot-spring tourism network list general bathing indications for Murasugi's radioactive spring. These are not treatment or personal health guarantees.
Since 1 January 2026, the facility lists admission at ¥400 for adults and ¥200 for children. Its price notice and current overview differ slightly on the child-age wording; confirm at the desk if visiting with an elementary-school child. A Niigata Prefecture tourism page still shows older prices and hours and is not used as the 2026 baseline.
How to read a bath profile
