1Nagoya Castle
Nagoya Castle was built from 1610 on Tokugawa Ieyasu's orders, its main keep once among the largest in Japan before WWII air raids destroyed most of the original structure. The Honmaru Palace, rebuilt over a decade using traditional materials and techniques, reopened in 2018 with reconstructed Shoin-style interiors, gilded sliding-door paintings, and carved transoms that give a genuine sense of Edo-period Owari Tokugawa splendor. The main keep itself is currently closed to visitors while the city plans a full wood reconstruction, a project that's been repeatedly delayed — check the current status before building a visit around going inside it. The castle grounds, with their stone walls and moat, are worth walking even without entering any of the buildings.
