This is a nice little spot to stop in for a more traditional Japanese Inn experience for your stay in Aoshima. From the outside, it appears like a large house with a trailer on the property and a yard space large enough to fit a few vehicles. There is a sign at the front door that lets you know it is the Sea-Dweller Inn.
The rooms are open Tatami with a table in the center. Cushions, sheets, blankets, pillows, etc are all found in the closet space to build your bed as you see fit. There is a toilet on both floors and a shower room in the downstairs, with the basic amenities needed. I arrived late at night and was greeted by the owner and his son. The owner spoke Japanese and his son could also translate in English. It was a very comfortable place to stay with a family business feel, rather than a chain hotel. Would recommend for a more authentic local experience.
