Mihara Castle, Japanese castle in Mihara, Hiroshima Prefecture.
Mihara Castle is a Japanese fortification in Mihara, Hiroshima Prefecture, built on a hill overlooking the Seto Inland Sea. The remains include stone walls, gate structures, and foundations of the former main tower, spread across several terraces that extend to the station level.
The Matsudaira clan began construction in 1567 to secure trade routes during the Sengoku period. Later modifications followed in the 17th century under new rulers who recognized the strategic value of the position.
The fort's name refers to its geographic position near the sea, and visitors today can still understand the placement that made maritime defense possible. The site shows typical elements of Japanese fortification design from the warrior period, including tiered stone walls and elevated platforms.
The fortification sits directly beside Mihara Station and can be reached through the station concourse without an entrance fee. The main area of the site can be explored on foot, with some paths featuring stairs and uneven surfaces.
During high tide, water encircles the foundation and makes the structure appear to float above the sea surface. This effect gave the fort the popular nickname floating fortress, which locals still use today.
