Nagoya Castle Hommaru Palace was constructed in 1615 on orders from Shogun Tokugawa Ieyasu, and served as both the residence of the lord of Owari Domain (modern-day western Aichi Prefecture) and the seat of government for the domain. In 1930, Nagoya Castle became the first castle structure to be designated as a National Treasure along with the main castle tower. It had won recognition for its splendor but both the main castle and the Hommaru Palace were destroyed by fire in the air raids of 1945.
Long-awaited restoration of the Hommaru Palace finally began in 2009, and the completed work was unveiled in June of 2018. The Hommaru Palace consists of 13 structures and the total floor space is 3,100 square meter. The architecture is early-modern Shoin-zukuri style which is one of Japan’s most important residential architectural styles. The interior is as resplendent as as the exterior, and boasts decorative fittings and painted partitions with traditional scenes of natural beauty. It is highly regarded for its architecture, paintings, and historical craftsmanship.
The restoration was carried out with painstaking accuracy toward the original via both traditional and modern methods and materials, making use of written records from the Edo period (1603-1868), early photos from prior to the second World War, survey blueprints, and a multitude of other sources.
