The museum complex in the Omoro-machi area of Naha, the capital city of Okinawa Prefecture. It opened in November 2007 and includes art, history, and natural history museums focusing specifically on Okinawan topics. The museum building, constructed largely of local Okinawan limestone, was designed with the imagery of Okinawa's gusuku (castles) in mind. It contains roughly 24,000 square meters of floor space on its four above-ground levels and one basement level. The art museum and history/natural history museum are located on opposite sides of a common lobby, and visitors can buy admission to one or the other, or a combination ticket.
