History / Origins (1)

Tell me about the inn's history.

Its predecessor, Menmentei Wataya, ran as an inn from the An-ei era in the mid-Edo period. The family name Wataya came from their cotton business, and they opened as a hot spring inn in the mid-Meiji period. The inn reopened after renovation in autumn 2013, combining modern facilities with the warmth of a long-established house.

Hot springs (1)

What kind of hot spring is Wataya no Yu?

Wataya no Yu is the only blended spring in Niigata Prefecture, mixing the Iwamuro Onsen source with source 3 of Tahoo Onsen Dairo no Yu at our sister inn. It is a sulphur-bearing sodium-calcium chloride spring (hypotonic and alkaline), whose sulphur content makes it very good for the skin, earning it the name the lustrous-skin bath. It is used straight from the source.

Hot springs / Views (1)

What is the view from the open-air bath?

From the open-air bath with its view on the fourth floor of the main building you can see Mount Shogaku, sometimes called Iwamuro Fuji and formed by a lava dome, and Mount Tahoo. You bathe while watching the mountains change through the seasons.

温泉地情報 (1)

What is distinctive about Iwamuro Onsen?

It has more than 300 years of history since the Edo period and was designated a National Health Resort Hot Spring in 1963. Known as a base for visiting Yahiko Shrine, its water is notable for its sulphur content and also has the character of a black spring. The Sea of Japan is about 5 minutes away by car, so fresh seafood is another attraction.

Meals (1)

What is distinctive about the food?

We serve creative dishes using Koshihikari rice grown organically on our own farm and seasonal Niigata vegetables. Our pride is the combination of dishes built on the best produce of the moment with fresh seafood from the Sea of Japan.

What is the Kinshoan?

It is a historic sukiya-style building dating from the Menmentei Wataya days, preserved in 2014 by moving the whole structure. It has been carefully kept as a symbol of the inn even after the new Wataya was built, and it conveys the atmosphere of an Edo-period tea-house annex.
