View of the magnificent Tokachidake Federation from the open-air bath

There are two sources, brown hot water (,which contains plenty of iron) and acid hot water. The hot spring is open for both overnight stays and day trips.

* Acidic hot water may not be available in winter. In addition, the open-air bath of Koiwa no yu (women's bath) may not be available because the temperature is low during winter. Thank you for your understanding. For details, please see "Ryounkaku Onsen Information" at the bottom of the page.
