The project of Dai Nihon Shiryo was originally intended to compose an official general history in order to address a notable gap in the national historical records after the Six Kingdom History. However, the project later transitioned towards creating and compiling a collection of historical materials. The writing style of Dai Nihon Shiryo is heavily influenced by the editorial style presented in "Shiryo," a historical record gathered by Wagakou Kodansho, a historical institution founded in the Edo period.
