Yamagata Yamagata City
A long-established Zao inn with natural onsen water fed straight from the source and nine baths of different character
Miyamaso Takamiya is an onsen inn in Yamagata City, Yamagata Prefecture. Founded in 1716, the first year of the Kyoho era, this long-established inn has watched over Zao for 300 years. Its own spring wells up in abundance, and its strongly acidic, sulfur-bearing water flows into all nine baths in the building straight from the source, never recirculated. From Choju-no-Yu, where black-lacquered board walls speak of its history, to Seseragi-no-Yu, where you can listen to the murmur of the river, you can enjoy genuine onsen water in baths of different character. There is also a private bath of Shigaraki ware and a room with its own open-air bath fed straight from the source, for a luxurious soak in privacy. Held in the nature of the deep mountains, you can spend blissful moments that make you forget everyday life.

A main bathhouse that keeps much of the atmosphere of a historic bathing retreat for healing stays, with black-lacquered board walls and thick crossbeams. In the semi-open-air “open-air tub bath,” crafted by traditional Yamagata artisans, you can soak while enjoying a pleasant breeze. Because there is only one open-air tub bath for both men and women, the men’s and women’s sides swap each day. Strongly acidic sulfur-bearing water from the inn’s own source flows straight in, never recirculated, and its tingling sensation and the scent of sulfur heighten the onsen atmosphere.

A main bathhouse where you can hear the murmur of a rare river of flowing onsen water that runs into the Sukawa River. It is divided into two: the Zao Stone Bath, with an open-air bath of natural Zao stone, a footbath and an indoor bath, and the Hinoki Bath, with a hinoki bath and an open-air tub bath; the men’s and women’s sides swap each day. Both are filled with strongly acidic sulfur-bearing water from the inn’s own source, fed straight in, never recirculated, and you can spend a soothing time wrapped in the sound of the river and the clear air.

A private bath where you can have the inn’s own source all to yourselves, without a thought for anyone else. Strongly acidic sulfur-bearing water flows lavishly, straight from the source, into a large tub made of Shigaraki ware. In the stillness, only the sound of the water can be heard, and you can savor fine onsen water to your heart’s content.

The open-air bath that belongs to Hinagura, a guest room in a converted traditional storehouse. It is the only in-room open-air bath in Zao Onsen fed straight from the source, never recirculated, and you can have the strongly acidic sulfur-bearing water from the inn’s own source all to yourself whenever you like. Enjoy a private soak where no one will disturb you.
