Kohoku Tennen Onsen Yuttari COCo is located in the Kohoku ward of Yokohama, Kanagawa Prefecture, on the outskirts of the capital. Sodium-chloride thermal water flows at 41°C through an indoor bath, a rotenburo, and a sauna.
Insider tip — Kohoku ward's 'Yuttari COCo' (ゆったり — leisurely, relaxed) is a neighborhood natural-spring spa drawing Yokohama's signature dark black water from deep underground. The name captures the Japanese ideal of unhurried bathing: arrive early, stay long, move between indoor and outdoor baths at a pace that city life rarely allows.
