An adults-only accommodation with just eight rooms, designed for enjoying Onsen and cuisine. Each room features a private open-air bath with panoramic views of Sagami Bay.

“Sanga” is a refined Ryokan perched on a hill over 160 meters above sea level, beyond the bustle of central Atami, where you can savor exceptional cuisine and take in sweeping views of Sagami Bay and Atami’s secluded inner retreat. The name “Sanga” expresses both contrast and harmony—mountain and sea, everyday life and escape—and reflects our wish for you to spend time that feels “fully complete.” In this renewal, we are introducing a new special suite, “Akari,” which will serve as the heart of our warm hospitality. We will also refresh the furnishings of our existing guest rooms to create an even more comfortable space. At the same time, we are expanding our previously limited opening days, making Reservations available every day—including Mondays, Tuesdays, and Wednesdays. You can now enjoy weekday luxury whenever you like: a peaceful escape from weekend crowds, wrapped in silence and the sound of the waves. Experience ultimate hospitality—an elegant, elevated Japanese style reimagined with contemporary design. At the newly reborn Sanga, please enjoy your stay to the fullest as seasonal breezes drift by.
