All rooms feature natural hot spring open-air baths. A secluded retreat with 8 traditional-style houses.
A mountain preserving its natural beauty with seasonal flowers. A detached property, free-flowing hot spring, forest overlooking the sea, and a 6,000-tsubo walking path where you can enjoy seasonal harvests with a hand basket. A property reminiscent of a hometown, where you can rediscover what was forgotten in city life. All our staff eagerly await the day we can meet you.
We stayed here as a family. Above all, the in-room open-air bath with free-flowing hot spring water was outstanding, and it was memorable to relax while taking in views of Suruga Bay and the sunset. The setting, surrounded by abundant nature across 6,000 tsubo of grounds, was also refreshing and allowed us to unwind and forget about everyday life.Meals were served in a private dining room exclusively for each guest room, and we enjoyed them at a leisurely pace in a space with an irori hearth. The monthly rotating creative Izu kaiseki cuisine was delightful both visually and in flavor, and we felt the attentive hospitality throughout. We also enjoyed visiting the two reservable open-air baths, and it was a nice touch to have local milk after bathing.This is an Accommodation we would love to return to, and one we would recommend to families as well.
miyabihanabi 9/22/2026This was my fourth stay.The Room, meals, and service were all excellent,but above all, the bath was outstanding.Being able to soak while looking out at the sea without worrying about others is truly a luxury. With no fence or partitions around the bath, it feels wonderfully open.I would love to stay again.
