A hidden mountain inn where you can enjoy the panoramic nature of the Jintsu Gorge, a beautiful skin bath, and carefully crafted medicinal cuisine

Toyama Toyama City

"Jintsu Gorge Kasuga Onsen Tominowa" is a hot spring inn located in the quiet Kasuga Onsen area along the banks of the Jintsu River in Toyama City, Toyama Prefecture. It completed a rebrand and reopened in April 2026, offering a sustainable stay that lives in harmony with Toyama's rich natural surroundings. The daily changing baths, "Shizuka no Yu" and "Haruka no Yu," feature a salt-rich open-air bath and a large public bath with a pleasantly mild saline quality that is gentle on the skin. The weakly alkaline sodium chloride spring offers excellent heat retention and skin-beautifying benefits, while a full-fledged dry sauna, cold plunge bath, and locally sourced "fermented medicinal cuisine" create a blissful detox experience that helps you feel refreshed from the inside out.
