Nagoya Castle was constructed by the Owari Domain in 1612 during the Edo period on the site of an earlier castle of the Oda clan in the Sengoku period. Nagoya Castle was the heart of one of the most important castle towns in Japan, Nagoya-juku, a post station on the Minoji road linking two of the important Edo Five Routes, the Tōkaidō and the Nakasendō. Nagoya Castle became the core of the modern Nagoya and ownership was transferred to the city by the Imperial Household Ministry in 1930. Nagoya Castle was destroyed in 1945 during the bombing of Nagoya in World War II and the reconstruction and repair of the castle has been undergoing since 1957.
