The breathtaking scenery
To Our Guests
At 10:00 on October 16, the volcanic alert level for Mount Tokachi was lowered to "2."
Concurrently, the scope of restrictions has been adjusted: the previous ban on entering the mountain has been replaced by restrictions limited to the area around the crater.
(Please check here for details regarding the restrictions around the crater.)
〇The temperature of the outdoor bath is low during winter. Please warm yourself up in the indoor bath before going outside.
〇The picture of the outdoor bath is the view from the men's outdoor bath. The women's outdoor bath is mainly cave-style. The bathes are switched in the evening, so over-night guests can enjoy both styles.
The beauty of nature is above the clouds.
Experience the panoramic view in a mountain top in altitude 1280m.
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.
