On tiny Yokoyama Island, this small inn has painted its name in large letters on the red roof. Ishiyama-so is a two-minute ferry ride from Kashikojima; phone the day before and your hosts will meet you at the quay. The inn isn't fancy, but it offers well-maintained rooms overlooking the sea. You'll find tea sets and yukata (Japanese bathrobes) in both the Japanese- and Western-style rooms, and breakfast and dinner plans are available.
Ago-cho, Yokoyama-jima, 517-0502, Japan
