A stunning Property with open-air baths in every room, nestled in a tranquil mountain setting with views of Mount Tanigawa.
Senju-an, a villa located in a tranquil mountain valley along the murmuring stream. We offer the highest quality relaxation space, harmoniously blending traditional Japanese and modern styles, with the seasonal backdrop of Mount Tanigawa.
Bettei Senju-an always welcomes us warmly.This time, my husband had sprained his ankle, and they kindly went out of their way to drive us, which truly moved us.All of the staff are genuinely kind, and it is a special place where we feel happy and relaxed every time we visit.
キンドレッド田中幸子 3/13/2026This is my third stay, and each time I visit, it feels like I’ve “come home” to this special Ryokan.The building is full of character, and the spacious grounds have a timeless charm that reflects its history.You can truly feel the changing seasons, and simply taking a walk around the property is enough to leave you feeling refreshed and fulfilled.The large public bath was spotless and very comfortable to use.The meals are also excellent, and I look forward to them every time.Above all, I’m always moved by the warm hospitality and thoughtful care of the staff.It’s a Ryokan where you can relax completely during your stay and naturally find yourself thinking, “I want to come back again.”I would love to continue staying here in the future.
