With the opening of the Birthplace of the Miyazaki Brothers to the public, the Miyazaki Brothers Museum opened in 1991 to exhibit historical materials related to the Miyazaki brothers and the Chinese Revolution, and share their significant contributions to history.

The first floor focuses on the Miyazaki family in Arao, including historical materials relating to the brothers and their father, Masataka, who instilled in them their egalitarian ideals. The second floor exhibits materials related to Toten Miyazaki and Chinese revolutionaries, showcasing the history of exchange between them, as well as the role of the Miyazaki brothers in world history. In particular, the plaque handwritten by Sun Yat-sen and his close associate Huang Xing is a must-see historical artifact that highlights the depth of their connection with the Miyazaki brothers.
