Introduction of Hot Springs (Onsen)

Near Atami Onsen, Suruga Bay hosts this hot spring. "Hashiri Yu" (Running Hot Water) is said to have been found 1300 years ago, and other source springs are in each inn.

In so-called "Atami Onsen's Inner Room", there is no blight resort, but the inns stand along the shore sandwiched by the steep ridge and the sea. There are seven lodgings, one public bath, and a membership-only resort hotel.

The view of the bright sun rising over the panoramic Suruga Bay is breath-taking, and you can see the Izu Oshima and six other Izu islands afar on a clear day.
