  • The Facility is modern, but the convenience is not great; the food is excellent.

    The property had been renovated last year, and it was lovely with a modern Japanese style. However, the lighting was too dim and felt a bit inconvenient, so it would have been nice to have adjustable lighting. Also, the bed was quite low and there was only a floor chair, which might be tough for elderly guests.The bath left my skin silky smooth, and the effect lasted even after I got home. Wonderful.Niigata edamame was offered as a welcome service—local produce really is delicious. The meals were also very tasty. There was a wide selection of alcohol, which I enjoyed. I’m grateful to the staff for accommodating my requests without showing any displeasure. Thank you very much.
