Arrival to this delightful hotel is by a 45-minute bus ride (on a public bus), but worth it.
Rooms are enormous, with everything one could possibly wish for, including a private onsen in the room in the form of a large bathtub full of the same thermal water as the larger onsen in the property. Beds are supremely comfortable, and everything is designed with the guest in mind.
Food, service and the facilities are all impeccable.
The place is full of little details (drinks, rest areas, sitting rooms).
We booked private onsen for both nights we stayed there, and they were delightful, tasteful and very enjoyable.
If I had to say anything negative, it would be that the stairs all over the hotel are very steep, with tall steps, which might make it challenging for some guests.

The hospitality shown to us made it an unforgettable experience. We definitely want to come back.

We stayed for one day in December 2023. When we arrived in the late afternoon, we were seated in the waiting room and brought tea and light snacks. A staff member named Koji greeted us. He was not very comfortable with English, but it meant a lot to us that he tried his very best to speak English, rather than shying away. He patiently explained the history and features of the ryokan to us. And he even tried to get to know us, asking about our purpose for visit (birthday celebrations) and where we're from.

The room itself is so spacious and has everything you could want. I particularly enjoyed the warm electric blanket that was thoughtfully set up so that when we checked in, we could defrost. The coffee, tea, and snacks within the room were delicious and high quality.

There are private and public (separated by gender) onsen. The private ones require reservations, which we did not have trouble making at all. There was a room available whenever we wanted to go.

The lobby has various beverages including juice, beer on tap, sake, and coffee.

The dinner and breakfast were incredible. There were so many courses, and a lot of variety. The presentation was beautiful also, very instagram worthy. We enjoyed every single dish, and were impressed that there was premium sushi and waygu beef also. Koji had informed the restaurant about our birthdays, so they surprised us with a birthday dessert! It is these little personal touches and acts of thoughfulness that really made us enjoy our stay.

TLDR: Incredibly hospitable staff, thoughtful details, wonderful accomodations and food. Highly recommend
