Ako Castle (Ako City, Hyogo Prefecture)
Overview (history, characteristics, attractions)
Ako Castle is a flatland castle (built on flat land) from the Edo period located in Harima Province (present-day Ako City, Hyogo Prefecture), and served as the center of the Ako domain's administration as the domain headquarters. Built in the early Edo period, it has since become associated with the Ako Asano family (Asano Naganori) and the tale of "Chushingura" (Ako Gishi), making it popular with history buffs and tourists alike.
The castle ruins have now been developed as a park, and you can stroll around the remains of the moat, stone walls, and the remains of the Honmaru and Ninomaru citadels. Around the castle ruins, there are information boards and exhibits introducing the historical site, as well as restored gates and turrets, making it a spot where you can get a real feel for history. The area is also attractive for its scenic location near the sea and its popularity as a cherry blossom viewing spot.
