About
A small ryokan near the beach at Hamasaka onsen, welcoming up to four groups a night. The bath is filled with Hamasaka's hot-spring water, salty and warming, and can be reserved for a private soak on request. Reviews mostly talk about the crab-course dinners, served in a private dining room, and the quiet, old-fashioned feel of the place: tatami rooms, a beach close enough to hear the waves, and small dogs and cats welcome to stay with their owners.
