Nihon Shoki is the first of the “Rikkokushi” compiled by ancient Japanese officials. It records the early history of Japan since the age of mythology，and its “historical book character” is beyond doubt. At the same time，the myths and legends in the text and the use of political culture have also created its “divine book character” as a political and religious classic literature. Since the Medieval，the character of historical books has declined，and the character of divine books has become more and more important. The commentary and research activities in the Medieval promoted the development of Shinto thought and established the dominant position of the character of the Holy Book. In Early modern period，“the unity of Shinto and Confucianism” has become popular. The interpretation paradigm created by the great scholar Hayashi Razan based on the separation of the duality of characters，together with the revival of history editing activities，has promoted the “return” of the historical character of Nihon Shoki.
