Tochigi Nasu Town
A hidden retreat where you can unwind in a free-flowing hot spring of the same quality as the Nasu Imperial Villa, together with a soothing mist sauna
Jizaiso, Kokoro no Oyado is a warm, welcoming hot spring inn in Nasu Town, Tochigi Prefecture, surrounded by the rich natural beauty of the Nasu Highlands. The hot spring uses Jizono-yu, a simple hot spring of the same quality as the one supplied to the Nasu Imperial Villa, and you can enjoy it in a free-flowing open-air bath overlooking abundant nature. The open-air bath also features a jacuzzi, a half-body bath, and a mist sauna that gently encourages perspiration with comforting warmth. There is no cold plunge bath, but you can feel Nasu’s refreshing breeze in the outdoor air bath space, where the sound of the river flowing nearby creates a deeply soothing stay for both body and mind.
A large bath using Jizono-yu, a simple hot spring that is also piped to the Nasu Imperial Villa. The open-air bath overlooking rich nature is offered as a luxurious free-flowing spring bath with no circulation at all, and it also features a jacuzzi, a half-body bath, and a mist sauna. The indoor bath uses partial circulation and filtration. You can fully enjoy this skin-friendly beauty bath to your heart’s content.
A semi-open-air private bath where you can enjoy the hot spring in a private setting while listening to the sound of the stream and rustling leaves. Guests staying overnight may use it freely and as often as they like for free during open hours, on a first-come, first-served basis, with an inner lock and no reservation required. You can enjoy a quiet, restorative moment all to yourself with family or someone special.
A soothing mist sauna located in the open-air bath area of the large bath. Warm, ultra-fine mist gently wraps around the whole body, warming you deeply from within without placing strain on the body. With its high moisturizing effect, it is a relaxing space that helps hydrate the skin while you unwind.
Day-use bathing is available from 13:00 to 18:00 (closed on Tuesdays, Wednesdays, and Thursdays; please confirm in advance)
