An accommodation limited to 8 groups per day, offering local cuisine and a retreat from the hustle and bustle of the onsen town.

[Awarded TripAdvisor Japan’s Top 25 Ryokan for five consecutive years] Step through the small gate lit with amber-hued lanterns, and you’ll be embraced by the warmth of beautifully polished wood. Surrender to a gentle sense of nostalgia, unwind at your own pace, and let your mind be set free in this hot-spring village—an oasis of quiet in the forests of Shima: Shima Onsen Tokiwasure no Accommodation Kamoto.

  • Once again, we had a truly relaxing stay, thanks to the warm and welcoming staff and the Room.However, one of our highlights here is the dining. Last time, every detail felt so thoughtful and considerate that it was comforting from the inside out.This time, that level of care didn’t come through as much, and it felt a bit more “wild,” which was disappointing.That said, the staff’s hospitality is genuinely wonderful.

  • It was a wonderful Ryokan in every respect—hospitality, open-air bath, and meals. I would stay here again.
