Abstract: Before the end of WWⅡ, a view of history called the Kou Koku Shi Kan, in which Japan is regarded as a divine nation created by deities and governed by emperors in a single family line from its beginning, emphasizing the independence of the formation of Japan, was the mainstream thinking among Japanese history academics. Meanwhile, few academics,in their study of the history of Japanese society, took Japanese history as a part of the history of East Asia. Until the end of WWⅡ, influenced by the social ideological trend of democratization, Japanese history academics began to break up the old “selfsatisfied” view, while reconsidering the development pattern of Japanese history by objectively analyzing the relevance and interactions between Japanese history and East Asian history, in order to better grasp the history and future of their country.Ancient Japanese state was formed under the influence of East Asian international environment. Based on this view, this article will analyze characteristics of Japanese state in its early stage.Ancient Japanese state was formed under the influence of East Asian international environment.
