Midorinoyado Okabekan Atami

Midorinoyado Okabekan is a traditional ryokan in Atami drawing chloride-rich geothermal waters from one of Japan's most historically significant hot spring cities, where geyser eruptions documented in the Nara-period chronicles (724 AD) and the legendary tale of Hojo Soun bathing here before his 1495 conquest of Odawara Castle connect thermal bathing to Japan's most dramatic feudal political transitions. Atami's remarkable thermal water pressure — the Ōyu geyser once erupted 800 meters skyward in natural eruptions before engineering interventions — reflects an extraordinarily concentrated geothermal system in the Izu-Hakone volcanic arc that produces Atami's consistently high-quality sodium chloride therapeutic water. The Atami Castle museum's overview of Sagami Bay and the surrounding Izu Peninsula, the MOA Museum's extraordinary ancient Japanese and Chinese art collection donated by the religious philosopher Mokichi Okada, and Atami's ongoing cultural revival create a richly layered resort experience around the historic chloride thermal bathing.
