A mineral-rich outdoor onsen fed directly from the source
Breathe cool mountain air while taking a dip in Ikaho Onsen’s open-air bath.
The bath is fed by water directly from the source, which emerges as a brownish-red, iron-rich water called “Kogane no Yu," meaning "golden water." This is one of two types of onsen water in the town, and it has also earned a reputation for purportedly helping boost women’s fertility by warming the body and improving blood circulation.
