The Tokugawa Art Museum (徳川美術館 Tokugawa Bijutsukan?) is a private art museum, located on the former Ōzone Shimoyashiki compound in Nagoya, central Japan. Its collection contains more than 12,000 items, including swords, armor, Noh costumes and masks, lacquer furniture, Chinese and Japanese ceramics, calligraphy, and paintings from the Chinese Song and Yuan dynasties (960-1368).
Unlike many private museums in Japan, which are based on collections assembled in the modern era by corporations or entrepreneurs, the Tokugawa Art Museum houses the hereditary collection of the Owari branch of the Tokugawa clan, which ruled the Owari Domain in what is now Aichi Prefecture. The museum is operated by the Owari Tokugawa Reimeikai Foundation, which was founded in 1931 by Yoshichika Tokugawa (1886–1976), 19th head of the Owari clan, in order to preserve the clan's priceless collection of art objects, furnishings, and heirlooms.
The main building of the museum was constructed in the 1930s in the Imperial Crown style, a mix of classic Japanese style with western elements.
The permanent exhibition also shows historical reproduction of the Nagoya Castle Ninomaru palace living quarters of the Owari Tokugawa daimyō, allowing visitors to view the objects as they were actually used in settings such as a Japanese tea-house or the Noh stage of the palace. The museum also mounts temporary exhibitions in a building that has been declared a national cultural property.
