Hakone Wellness & Spa — The Finest Five-Star Stays

Hakone is built around bathing. Its hot springs come in several varieties fed by volcanic activity, and many properties offer indoor and outdoor baths as well as private ones you can reserve. Pair soaking with forest walks along the old Tokaido road, where cedar-lined stone paths still run between villages. Many resorts add spa treatments and seasonal, vegetable-forward kaiseki menus that make a few days here a genuine reset.
