Inamuragasaki Onsen, in the coastal Inamuragasaki area of Kamakura, Kanagawa Prefecture, offers sodium-chloride thermal water at 40°C. It offers an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — Inamuragasaki Cape is one of Kamakura's most historically charged sites: in 1333, the warrior Nitta Yoshisada reportedly threw his golden sword into the sea here as an offering to the Dragon God, and the tide receded to allow his army to pass — ending the 150-year Kamakura Shogunate in a single assault. The onsen faces Sagami Bay at sunset, with Enoshima Island and the Izu Peninsula silhouetted on the horizon. Few Japanese hot springs pair historical drama with coastal beauty so perfectly.
