Katsuura Castle

Katsuura Castle stands on Hachiman Cape with defensive earthen ramparts and moats strategically positioned above steep cliffs that drop toward the Pacific Ocean. The fortification's design integrates the natural coastal terrain to create a fortified position that took advantage of the dramatic landscape.

The fortification was built around 1534 and served as a stronghold for the Masaki clan until 1590, when Tokugawa forces under Honda Tadakatsu captured the site. This takeover ended local rule and brought the region under control of the expanding Tokugawa authority.

The site holds connections to Lady Oman, daughter of lord Masaki Yoritada, whose life story linked this coastal fortress to the prominent Tokugawa family. This personal connection remains part of how locals understand the place's significance.

The castle grounds now form part of Hachiman Cape Park and can be reached by walking from JR Katsuura Station on the Sotobo Line. The site is exposed to ocean winds and weather, so plan your visit for when conditions are favorable.

The site exemplifies the umijiro style, a castle design that deliberately incorporates coastal terrain formations to gain military advantage. This approach to fortification is relatively uncommon in Japan and reflects the ingenuity of the local rulers in adapting to their environment.
