About

Kesennuma Plaza Hotel stands on a hill above the harbor, with separate outdoor and indoor baths for men and women looking out over Kesennuma Bay toward Oshima island. The natural hot-spring water is drawn from 1,800 meters underground and has a strong salty edge that keeps you warm well after you get out. Each side also has a sauna and a cold plunge. Guest rooms and the dining room share the same bay view, and the restaurant leans on fresh local seafood.
