Nagoya Castle is a Japanese castle located in Nagoya, central Japan. During the Edo period, Nagoya Castle was the heart of one of the most important castle towns in Japan, Nagoya-juku, which was a post station on the Minoji road linking two of five important trade routes, the Tōkaidō and the Nakasendō.
Another way of pronouncing Nagoya Castle is Meijō (名城). This name is used for many city institutions, such as Meijō Park, the metro's Meijō Line and Meijo University, reflecting the cultural influence of this historic structure.
