  • Enjoy a great view from the bath.

    The view from the open-air bath is amazing. I was able to relax in the free-flowing Onsen. The meals were very delicious and satisfying. Since each dish is served individually, I could enjoy my meal at a leisurely pace. I was curious about something that looked like a red bridge in the distance from the dining area, but it seems to be part of an airport facility. The Room is spacious and comes with a massage chair and an open-air pot bath, which also made me very satisfied. There are many Reviews saying the building is old, but does that cause any inconvenience? It didn’t bother me at all. The staff were very kind and soothing. Please let me stay again.
