As of the end of March 2020, the museum's own collection numbered 1,911 items, including 13 National Treasures and 114 Important Cultural Properties. It also looked after 1,974 works on deposit, among them 52 National Treasures and 306 Important Cultural Properties. Among the museum's best-known works are the Silk-painted Eleven-faced Kannon and the Hell Scroll, called Jigoku Zoshi. Every autumn the museum holds its Shosoin Exhibition, presenting items from the Nara-period imperial repository at Todaiji Temple. The link goes back a long way. In 1931 the museum held an exhibition of the fragmentary textile treasures of the Shosoin, to show the results of restoration work. Its Nara Buddhist Sculpture Hall, which reopened in 2010 in the Main Building, offers a way into Nara's long story as capital through sculpture. The museum is not only a place for display. The Conservation Center, opened in 2002, exists to rescue, examine, document, conserve and restore National Treasures and other key cultural properties. Restorers who specialize in sculptures, paintings and ancient texts work there, and specialists advise the people who own and look after cultural assets. In a way, this continues the rescue mission that began in 1895.
