Oofunato Onsen is a hot spring ryokan on the Sanriku coast, built above Ofunato Bay in Iwate. The indoor bath is a wide room with big windows over the water and both a hot tub and a cooler one, and the rotenburo outside catches the sea air and the sound of the waves. The water is faintly salty and heated over a wood fire, which keeps it soft on the skin. On the grounds there's also a free footbath, Fukko no Yu (復興の湯), open to anyone by the water. Guest rooms range up to a top-floor room with a wide sea view, and dinner leans on fresh local seafood. Reviewers often mention watching the sunrise from the open-air bath.
