Zushi Onsen is a popular hot spring in Zushi city on the Miura Peninsula of Kanagawa Prefecture, a beloved coastal resort town for Tokyoites known for its sandy Zushi Beach facing the sheltered waters of Sagami Bay. The chloride-rich thermal waters warm the body effectively and nourish the skin — ideal after a day of surfing, sailing, or beach walking along the Shonan coastline. The relaxed, creative atmosphere of Zushi — home to artists, musicians, and a vibrant local community — gives the onsen a distinctly contemporary, accessible character among the many coastal thermal options south of Tokyo.
Insider tip — Zushi Onsen draws sodium-chloride thermal water from the same coastal Sagami Bay aquifer system that feeds several nearby Shonan bathing establishments. The town's bohemian atmosphere, known as a seaside retreat for Tokyo artists and writers, extends into the bathing culture. Visit on a weekday autumn morning when the beachside crowds thin out and you can enjoy the sento in near-solitude.
