This facility opened in 2011 and is currently operated jointly by NOMURA Co.,Ltd. and the Morioka City Tourism and Convention Association as the representative "designated manager." It serves two purposes: as a cultural property exhibition facility housing the precious treasures of the Nanbu family, and as a base for "urban tourism" within Morioka Castle Ruins Park, where a variety of people, including local residents, tourists, and students on school trips, gather to experience the history and traditional culture of the castle town. NOMURA Co.,Ltd. has been involved in the preparations for the facility's opening as the designated manager, and is currently working to provide stable services for local residents and tourists who have been looking forward to its opening, while cherishing its dignity as a facility showcasing Morioka's treasures in the area affected by the Great East Japan Earthquake.
