Nezu Museum

During World War II, the museum's collection was safeguarded away from central Tokyo, avoiding the destruction suffered by the estate property during the bombing in May 1945. Exhibitions resumed after the war in 1946. Closed due to large-scale renovation and renewal starting in 2006, the museum reopened in the fall of 2009 with a brand new building designed by the Japanese architect Kengo Kuma. The museum is also famous for its garden. Drinking yuzu tea in the museum's cafe has been included as one of the best 30 Tokyo experiences in the Soul of Tokyo, a 2019 travel guide book.

The museum houses more than 7,400 cultural objects, seven of which have been designated by the Japanese government as National Treasures, 88 as Important Cultural Properties, and 94 as Important Art Objects (ja). The museum's collection of cultural artifacts covers a variety of disciplines, including painting, calligraphy, sculpture, metalwork, ceramics, lacquerware, wooden and bamboo craft, textiles, armor, and archaeological artifacts. Of the collection, the museum considers the byōbu (folding screen) Irises by Ogata Kōrin, designated as a National Treasure, to be the centerpiece of the collection. This byōbu is displayed for a limited time each year during a special exhibition from April to May to coincide with the blooming season of the irises planted in the museum's Japanese garden. Kaichirō Nezu acquired this byōbu in 1914, and even before the museum was founded, he held exhibitions and tea ceremonies to display it for the enjoyment of his many guests. The museum's collection also includes 1,200 of the 3,000 pieces of Japanese sword fittings collected by Meiji era industrialist Mitsumura Toshimo (1877－1955), making it one of the largest collections of Japanese sword fittings in Japan. The collection also consists of Chinese bronzes of the Shang and Zhou dynasties. In 2025, it was announced that a bell in the museum's collection had been taken from Korea during the Japanese colonial period. South Korean officials expressed interest in acquiring the bell and restoring it to the original government office in Jeju Province that it had been taken from. The museum declined to comment on the bell.
