Its old name is magnesium sulfate, common salt, and gypsum spring. Its hot spring quality is extremely rare.
Asahidake Onsen, located on the mountainside of Mt. Asahidake's highest peak (2291 m), was discovered in 1914 and is a prominent alpine hot spring area in Japan.
This area used to be called "Yukomanbetsu," meaning "river heading for the hot water" in the Ainu language,and you can learn about its old history.
The hot spring comes from the heat from the Daisetsuzan mountain range's continuous volcanic activity and the blessed water.
After all this time, it still wells up naturally.
