Wadamisaki Battery

Wadamisaki Battery is a coastal fortification in Hyōgo-ku, Kobe, constructed in 1864 with granite walls sourced from the Shiwaku Islands. The structure comprises a two-story building made from Japanese elm wood and represents one of the few remaining coastal defense installations from that era.

The fortification was built in 1864 under architect Katsu Kaishū as Japan sought to strengthen its coastal defenses during the final years of national isolation. The project reflected efforts to respond to external pressures as the country approached the end of the Tokugawa period.

The site was officially registered as a historic monument on March 3, 1921, becoming the first such designation in Hyogo Prefecture and reflecting its importance in Japanese military heritage. This recognition underscores how the structure serves as a marker of the nation's defense strategy during a pivotal period.

Access is available through Wadamisaki Station, which is about three minutes' walk from the entrance near Mitsubishi Heavy Industries. The site sits within an active industrial area, so visitors should be aware of traffic and check current opening hours before planning a visit.

Despite never being used for military purposes, it remains the only surviving coastal defense structure from the time when multiple similar installations were built around Osaka Bay. This makes it a rare example of the defensive architecture of that era that has otherwise been lost.
