Historic Castles and Ruins

Aichi Prefecture serves as the historic heart of Japan's feudal era, being the birthplace of the three great unifiers: Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu. This collection spans centuries of military and civil engineering, from Inuyama Castle—one of Japan's oldest original wooden keeps—to the Sengoku-period mountain ruins of Asuke. It also includes Meiji Mura, an open-air museum preserving architectural transitions from the 19th and early 20th centuries.
