Keikoku no Yu

Keikoku no Yu is a 12-room Japanese stay in Yamanouchi, Nagano Prefecture. Its hot-spring facilities include open-air bathing and indoor bathing using simple hot spring / simple sulfur spring. Some room categories include their own hot-spring bath, while a separate shared private hot-spring bath is not promised.

Room layout, bedding and attached-bath details should be matched to the specific category rather than assumed from the property name. Meals are described as kaiseki or seasonal Japanese-course dining with a connection to Nagano Prefecture. Child acceptance varies or is not stated property-wide and should be confirmed for the exact room.

Travel route: About 70 minutes by bus from JR Nagano Station, followed by the property pickup. Recheck the operating timetable and any reservation requirement before travel.

Choose the room category before comparing plans: bath access, bedding, meal inclusion and cancellation terms can differ even within the same property. If bathing is central to the stay, ask how private-use slots are allocated; if meals matter, verify where dinner and breakfast are served and whether the plan includes both.
