Innoshima Suigun Castle

因島水軍城

A castle-style museum commemorating the Innoshima branch of the Murakami pirates, a medieval naval clan of the Seto Inland Sea. It is one of the components of Japan Heritage.

Built in 1983 in castle style, this museum tells the story of the Innoshima branch of the Murakami naval forces, who dominated the Seto Inland Sea from the 14th to the 16th centuries. It displays armor, old documents and naval banners. Together with the Murakami Kaizoku Museum in Imabari, it forms part of the Japan Heritage “Murakami Pirates” sites. There is a view of Innoshima and the surrounding waters from the hilltop. Admission is about 330 yen, and it is closed on Thursdays. It is in central Innoshima, roughly 3 km off the main cycling route.
