Tennen Onsen Sendai Corona no Yu is located in Sendai, Miyagi Prefecture, the main city of northeastern Japan. Sodium-chloride water flows at 41°C, available in an indoor bath complemented by a sauna and massage service.
Insider tip — Tennen Onsen Sendai Corona no Yu is a large urban spa complex drawing naturally occurring sodium-chloride water from beneath the Sendai plain. The salt-rich water warms the body deeply and retains heat well after bathing, making it especially popular on cold Tohoku evenings. Multiple pools of varying temperatures, jet baths, and sauna facilities cater to every preference. Its convenient location near central Sendai makes it an easy stop after exploring the city's historic sites.
