The museum opened in November 2005, bringing together all the precious materials related to Nagasaki's international exchange. It attracted attention as the first prefectural museum to adopt a designated manager system that includes the curatorial department. Since its opening, Nomura NOMURA Co.,Ltd. has been involved in the facility's operation as the designated manager. While utilizing our comprehensive capabilities to hold exhibitions and events, we also actively engage in activities with the cooperation of local residents, such as having volunteers reenact court decisions in skits in the restored magistrate's office. The museum also serves as a research center for "Nagasaki Studies," and works in cooperation with the founder to operate a system that ensures the continuity of cultural administration.
