An onsen is an onsen :) Rakuten Stay Villa in Sengokuhara, Hakone. The water is clear, feels a little soapy, and has a faint hydrogen sulfide smell. The onsen itself is kakenagashi. It is on the 2nd floor of the villa. There are French doors leading to the balcony. They open fully, so it becomes a covered rotenburo 🌚 There is also an ashiyu downstairs. The water composition is attached.
