Atami Onsen is one of Japan’s oldest and most renowned hot spring destinations, with a history spanning over 1,500 years. It was a favored retreat of Tokugawa Ieyasu, the first shogun of the Edo period. Located along Sagami Bay, Atami is distinguished by its mineral-rich hot spring waters and dramatic seaside setting, making it a classic and accessible onsen escape from Tokyo.

The area offers a wide range of bathing experiences suitable for different travel styles:

• Ocean Spa Fuua – A modern luxury onsen featuring a signature infinity bath overlooking the ocean, creating a seamless visual connection between the hot spring and Sagami Bay. Ideal for scenic relaxation and premium spa experiences.
