Château de Matsuojo

Matsuo Castle sits on the eastern coast of Chiba Prefecture and displays Western-style fortifications with angled bastions and earthen ramparts. The site includes the Kikyo-dai platform featuring the Ota family crest pattern in its layout.

Construction started in 1869 under Ota Sukeyoshi but stopped in 1874 during the Meiji Restoration period. The project was never finished, marking a turning point in how Japan built its defenses.

The grounds display the family crest of the Ota clan woven into its design, showing how architecture carried family identity.

Today the castle grounds are occupied by a driving school where historical markers and fortress documentation can be viewed. It is best to check ahead and arrange a visit to properly see the site.

This castle was among the last built in Japan and used an unusual triangular fortification design. This approach differed sharply from traditional Japanese castle patterns and reflected Western military influence.
