Overview

Amagasaki Castle is an early-modern flatland castle in Amagasaki, Hyogo Prefecture, founded in 1617 when Toda Ujikane, a hereditary Tokugawa vassal, was installed as lord of the newly created Amagasaki domain with a stipend of 50,000 koku. After the Siege of Osaka, the Tokugawa shogunate placed Osaka under direct rule and sought a stronghold west of the city to check the western daimyo, ordering Ujikane to build the castle here.

Construction and Layout

Built over several years beginning in 1618, the castle precinct measured roughly 300 meters on each side, encircled by a triple moat and crowned with a four-story main keep. The town was laid out as a sōgamae, enclosing the castle, samurai quarters, and merchant district together, and it served as the seat of Amagasaki domain's administration.

Succession of Lords

After the Toda, the Aoyama clan took over, and from the Kyōhō era (late 1710s) the Sakurai-Matsudaira clan held the castle until the end of the Edo period, ruling a 40,000-koku domain.

Present State

Following the 1873 abolition edict, the castle's structures were torn down and its moats gradually filled in as the area urbanized. In the Heisei era, Akira Anbo, founder of a home-appliance retail chain, funded a reinforced-concrete reconstruction keep — built in the southwest of the former main bailey, a different spot from the original — which opened to the public in March 2019. The keep now houses a historical exhibition hall telling the story of Amagasaki's castle town.

Connection to Swords

No sword is recorded as having been passed down at Amagasaki Castle itself, but blades associated with the former Amagasaki domain and its samurai community are preserved at the Amashin Museum, operated by the Amagasaki Shinkin Bank. Alongside materials related to the old castle town, the museum permanently displays tachi swords and armor, including a National Treasure, among them a tachi signed "Morīe" that descended through the Sakurai family, complete with its ceremonial mounting. These holdings illustrate how tachi were owned and mounted by daimyo households in the Edo period, linking Amagasaki's castle town to the broader culture of the Japanese sword.
