Iwaki Yumoto Onsen Sahako no Yu

The locals' favourite hot spring with a history of more than 1,000 years where you can drop by for a soak.

The hallmark is its Japanese-style architecture that recreates a fire lookout tower from the late Edo period. It has an interesting appearance, which, at first glance, does not give away how many floors it has. Despite its history of more than 1,000 years, this hot spring is a go-to facility for the local public when they feel like taking a dip. The reasonable price is sure to please. The baths have a reputation for being a fairly hot temperature and are always busy with a large number of bathers.

There are two types of baths: a stone bath with a cascading hot spring called Takara no Yu, and an octagon-shaped cypress bath with a woody scent called Kofuku no Yu. In addition, persons with disabilities or families can reserve the Choju no Yu bath for private use (reservation required). No soap, shampoo or other toiletries are provided. You can either bring your own toiletries or purchase them at the front desk.

The sulphur smell of the baths gives the onsen a real hot spring atmosphere, and the water is said to be effective against skin diseases, gynaecological diseases, hypertension, and other ailments. It is a natural sulphur spring that is colourless and transparent, and which flows from the source.
