Innoshima Suigun Castle

因島水軍城

Innoshima Suigun Castle is a museum dedicated to the maritime warrior heritage of the Innoshima Murakami clan. Opened in 1983 under historian guidance, it presents arms, heirlooms, and documents connected to the inland-sea suigun world. Exhibition spaces include the main keep museum, Ninomaru galleries, and corner-turret photo displays, with notable holdings such as armor and medieval documents designated as Hiroshima Prefecture important cultural properties. The site works well as a focused history stop while touring Innoshima rather than a sprawling outdoor castle hike. Check local tourism notices for special exhibitions and festival-related displays. Come when you want concrete Murakami suigun artifacts and storylines in one compact visit.
