When was Nagoya Castle created?
Nagoya Castle
After various upheavals in Japan, Tokugawa Ieyasu emerged victorious and decided in November 1609 (Keichō 14) to rebuild the castle at Nagoya. Up until the Meiji Restoration, Nagoya Castle flourished as the castle where the Owari branch, the foremost of the three Tokugawa clan lineages, resided.  Castle construction technology had been extensively developed and consolidated since the construction of Azuchi Castle in 1576 by Oda Nobunaga (1534–1582). One of the main architects who designed and directed the building of the castle was Nakai Masakiyo, who was previously involved in the construction of the Nijō, Fushimi, Edo, and Sunpu castles. He had gathered and refined existing castle and fortification construction technology and techniques and ultimately formulated the standards for the Tokugawa shogunate's castles, as exemplified by Nagoya Castle.
