Aizu Ashinomaki Onsen Marumine Sansui (Private Villas)

A luxury resort with just six private villas, tucked away in Ashinomaki Onsen—Aizu’s hidden retreat. Each villa blends Aizu charm with comfortable, traditional Japanese design and offers a spacious layout of 70+ square meters. The largest villa, “Tangetsu,” spans 130 square meters and boasts stunning views from its veranda overlooking the mountain stream and the Okawa River.

Every room includes a 100% free-flowing private hot spring bath. You’re also welcome to use the large public baths at the connected sister properties, “Bekkan Kawaoto” and “Marumine Main Building.” Guests love the variety of hot spring experiences available right on the grounds. Dining is another highlight, with kaiseki cuisine featuring plenty of local Aizu ingredients and seasonal flavors—each dish carefully prepared and as beautiful as it is delicious.

With the soothing sound of the river just outside your window and mountain scenery that shifts with every season, it’s a place where both body and mind can truly unwind. Settle into a spacious villa designed for pure indulgence, and savor a relaxing escape from everyday life.
