The term "National Treasure" in the museum's name refers to "old" National Treasures of Japan, term which denoted all the state-designated Cultural Properties of Japanbefore the Law for the Protection of Cultural Properties came into force on August 29, 1950. All of the old national treasures became Important Cultural Properties and some of them have been designated as National Treasures since June 9, 1951. From a current perspective the name refers to a museum housing both Important Cultural Properties and National Treasures.
History
The Kamakura Museum of National Treasure was founded in April 1928 to protect important art works after the 1923 Great Kantō earthquake. The building, which was constructed in the same year, was modeled after the Shōsōintreasure house of Tōdai-ji, Nara. During World War II, in June 1945, part of the collection was evacuated to Kushikawa in Tsukui District in the northwestern part of Kamakura, and the museum was temporarily closed between August and October 1945. The items which had been moved returned in May 1946. In October 1952, the museum came under the jurisdiction of the newly established Kamakura CityBoard of Education. In November 1955 it joined the Kanagawa Museum Association. The "Foundation Ujiie Ukiyo-e Collection" was established in the museum in October 1974. In 1983 the museum's annex storage room was completed, and in May 2000 the main building was designated as a Registered Tangible Cultural Property.
Main Building
The main building is a two-story reinforced concrete construction with tile-roofing and a building area of about 800㎡. There is no basement. The construction resembles the raised-floor-style of an ancient log storehouse. It was designed by Okada Shinichirō, architect of the Kabuki-za theater and the Otaru branch of the Bank of Japan, and constructed by the Matsui Group. From the outside the building resembles Nara's Shōsōin treasure house, while techniques from Kamakura period temples have been employed on the interior. The ground floor is used as storage, while the second floor contains a single exhibition hall spanning almost 600m².
Annex
The annex is connected to the main building via a walkway on the second floor. Like the main building it is a two-story reinforced concrete construction featuring two floors above ground and a basement, with rooms for repairs and machines. The ground floor contains offices and the room of the curator, while the second floor is used as storage space.
Highlights of the Collection
The Kamakura Museum houses five National Treasures of Japan, 73 items designated as "Important Cultural Property", and other works of art. There are about 100 nikuhitsugaukiyo-e paintings in the "Ujiie Ukiyo-e Collection".
