The moat system was engineered to connect directly to the sea, allowing ships to enter the castle grounds for supply delivery.
The original castle was dismantled in the late 19th century following the Meiji Restoration, with only portions of the stone walls and moats surviving as original structures.
The current keep was reconstructed based on historical drawings and models to restore the silhouette of the original fortification.
The castle site includes a bronze statue of its founder, Todo Takatora, a renowned master of castle architecture.
The seawater moat maintains a high salinity level, which uniquely impacts the local ecosystem within the stone-lined trenches.
Imabari Castle is distinguished by its unique seawater moat, which draws water directly from the Seto Inland Sea. The current five-story donjon is a 1980s ferro-concrete reconstruction of the original castle built by Todo Takatora in 1604. It functions as a historical museum housing a collection of Edo-period armor, documents, and historical artifacts. The castle grounds feature extensive stone walls and moats designed for maritime defense. Visitors can ascend to the top floor of the keep for panoramic views of the Imabari cityscape and the Kurushima-Kaikyo Bridge. The site is a prominent example of a 'mizujiro' or water castle in Japan. It was intentionally built on the coast to facilitate naval transport and trade control.
