Tounosawa Onsen
Fresh natural hot spring water that gushes out 70 tons a day from its own source. The spring quality is a weakly alkaline simple spring, which feels smooth and gentle on the skin, and after bathing leaves the skin silky and smooth. It is known as both the “hot spring for fertility” and the “hot spring for beautiful skin.” From the large bath and the open-air bath, which look out closely over the clear Hayakawa river, you can take in Hakone’s magnificent seasonal nature and trees while listening to the pleasant murmur of the river, letting exceptional relaxation and warmth sink all the way into the core of your body.
