Naruko Onsen Yumoto Kissho
A Kyoritsu Resort inn with four free reservable onsen baths — rare in Naruko — plus special rooms and annex suites with free-flowing onsen in the room.

A 300-year-old spring inn with four different own-source waters — one bath can be switched to private use, and the baths run around the clock.
The private bath works like this: you book it, it's yours. Door closed, steam up, nobody else's schedule anywhere near you. Take the late slot — night air on wet skin is the whole point.



Private-bath and water facts were checked against the property's official site and Japanese booking pages in November 2026. Room plans change — confirm the private bath is included in the plan you book.
