  • It was excellent!

    I will definitely visit again! A Ryokan that gets repeat guests always trains their staff to greet every guest warmly. Every time you pass by, they greet you. This is a common trait of highly-rated places I’ve visited before. Greeting every time you pass by—it’s a way to ensure they never forget the spirit of hospitality! Please stay just as you are now! I once revisited a place after a year, and the service had become so terrible that it was disappointing and even infuriating. This was truly the best day ever! Thank you so much.

    We stayed here for a family trip. There are two large public baths, each with an open-air bath, which was excellent! The buffet meals were abundant in variety and everything was very delicious. The live kitchen served warm, freshly prepared dishes, which made us very happy! One minor inconvenience was that the children's chairs in the dining area did not have belts. Since our child couldn't sit still and tried to stand up, it made feeding a bit challenging. However, the buffet had plenty of menu options that children love, which was very helpful! Another slight concern was the dryness in the room; perhaps it’s due to the season and unavoidable. Other than that, we experienced exceptional hospitality and had a stress-free stay at this accommodation. We would love to visit again!
