This is the only public bathhouse in Noboribetsu Onsen.
Because you can bathe in hot spring water quality for a very low fee it is very popular.
Although there is only an indoor bath, visitors can enjoy two types of spring water: alum spring (myobansen) and sulfur spring (iōsen).
The facility is still new, having reopened in 2015, and is well cleaned and spotless.
However, amenities such as towels and shampoo are not provided, so you will need to purchase them or bring your own.
