The spring is 100% sodium and calcium sulfate spring water. It keeps you warm and promotes blood circulation, and is expected to help with poor circulation, fatigue, and back pain and neuralgia. It is known locally as a "kotatsu-less bath," and it warms you from the inside out, even in winter.

The hotel has a total of 10 types of baths, including a stone bath, a cypress bath, a rock bath, an open-air kettle bath, and a multi-purpose bath, so you can enjoy bathing in different styles. The open-air kettle bath in particular is modeled after a large kettle, which is the name of Nanakama Onsen, and is full of a sense of openness. There is also a sauna and a washing area, and towels and bath towels can be purchased or rented for a fee.

[Concerns]
The hotel is closed twice a month, so please check the official website or call before visiting. The store in the hotel only serves drinks, and no meals, so we recommend bringing snacks with you. The nearby foot bath "Shirasagi no Yu" may be closed.
