The Dai Nihon Shiryo (大日本史料) is a collection of historical documents from the ninth to the seventeenth century, published by Historiographical Institute of the University of Tokyo in 1901, and is still being published.
Volume 12 of Dai Nihon Shiryo still remains incomplete.
[2] 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.
