The Otomeza Theater in Mitarai on Osaki Shimojima is a fine example of a small provincial theater from early in the twentieth Century.
It was built in 1930 when the port had become less important than in the days of wind, but was still important as an "entertainment" area.
In 1950 it switched to being a movie theater, but following the outlawing of prostitution in 1956 the town went into serious decline and the theater closed. For a while it was used as a vegetable market.
It has been lovingly restored to its former glory and is a rare example of the kind of small theater that were found all over Japan. Like all thge historic sites in the town, entrance is free.
