"We stayed one night at Kasuitei Ooya, and it turned out to be the highlight of our time in Japan. The ryokan gets the traditional experience right without it feeling staged — tatami rooms, yukata, and a real sense of care in everything. Our room had a lake view and a private bath, which our teenagers enjoyed as much as we did.
The kaiseki dinner was outstanding: beautifully presented course after course with local ingredients we didn't see anywhere else on the trip, and breakfast the next morning was just as good. The onsen is on the 7th floor, and the same floor has a viewing area where we caught the clearest Mt Fuji view of our stay at sunrise.
What tied it all together was the staff. From check-in through to the shuttle back to the station, they were warm, unhurried, and seemed to anticipate what we needed before we asked. If you're deciding whether to build a ryokan night into a Japan trip, this is the place to do it."
