Abstract：The duality of the Sino-Japanese conflict， the duality of the Sino-Japanese structural conflict and the tradition of Japans continental strategy result in the strategic rivalry and competition between the two countries. In recent years， due to the right deviation of Japanese domestic policies， this rivalry and competition tend to seriousness. In light of this， China should make its measures more strategic， comprehensive and initiative in the struggle with Japan， which means fully recognizing that China is a relative country to the Japan Sea in geostrategy and the Japan Sea in the future regional and global politics is important. In the current struggle with Japan， China should build its northeast as the frontier， change the main forefront from the East China Sea to the Japan Sea， and strengthen the military， economic and political power. According to the analysis， this paper argues this geostrategic shift focuses on the struggle with Japan in the short term and looks for the regional and global political trend in the long term．
