Kamogawa Sea World Hotel

The hotel sits right beside Kamogawa Sea World, with the aquarium reachable directly from the lobby. Every room faces the Pacific. The indoor onsen hall is split into two bathing rooms, one for each gender, and the water carries a faint scent of sulfur; the guest rooms themselves have only an ordinary unit bath, so the hall is the only place to soak in onsen water. It's built around families: the bath keeps baby gear and toys on hand, and the buffet restaurant has its own kids' corner.
