The museum, which was converted from the Japanese military hospital in World War II, is opposite the Sugar King Park. The museum contains documents from the Japanese period, the World War II period, the historical materials of the indigenous folk customs of Tanmoro and Karolan, and the porcelain, copper coins and other cultural relics recovered from the 18th century. In short, a trip to this museum can make the Northern Mariana Islands known about the past and the present.
