The National Museum of Art (国立国際美術館 Kokuritsu Kokusai Bijutsukan?) is a subterranean Japanese art museum located on the island of Nakanoshima, located between the Dōjima River and the Tosabori River, about 5 minutes west of Higobashi Station in central Osaka.
The official Japanese title of the museum translates as the "National Museum of International Art". The museum is also known by the English acronym NMAO (National Museum of Art, Osaka).
Designed by architect Arata Isozaki. The museum originates from the Expo Art Gallery which was built as part of Expo '70, held in Suita in the outskirts of Osaka. The site was converted into Expo Commemoration Park after the Expo, but the gallery was preserved for possible future use as a permanent art museum. It re-opened in 1977 as the National Museum of Art, as part of the Expo Commemoration Park. Due to the aging of the building as well as growing space limitations, the museum was temporarily closed in January 2004. The old museum was demolished and turned into a car park, while the exhibits were transferred to its more central, current location in Nakanoshima, which opened in November 2004.
Most of the artwork in the collection is from the post-war era. Pre-war exceptions include work by Paul Cézanne, Pablo Picasso, Max Ernst, Tsuguharu Foujita and Yasuo Kuniyoshi.
The museum structure is itself an example of the modern architect's art. The present museum was designed by international architect César Pelli. Most of the museum facilities are located underground, next to the Osaka Science Museum. Pelli suggested that the externally visible design structure represents waving reeds in the wind.
