The article deals with the transformation of Japan's modern strategy towards China. China and Japan are the most powerful economic, political and military powers in East Asia and constitute the two main centers of power around which the regional subsystem of international relations is being formed. The rise of China is the most significant challenge for Japan's entire foreign policy, but it also offers enormous opportunities for the country's development. And the future positions of not only Japan and China themselves, but also stability in East Asia depend on what Japan's strategy towards China will be. Japan's strategy towards the PRC after World War II until 2010–2011. can be characterized as the predominance of involvement with elements of containment: the policy of Japan as a whole contributed to the realization of the main foreign policy goal of the PRC - the restoration of the status of a great power, which China lost during the opium wars of the mid-19th century. In the 2000s there was a reassessment and activation of Japan's foreign policy. There are two opposite assessments of Japan's strategy towards China in the 2000s: one group of researchers believes that there has been a shift towards balancing, and the other believes that such a change has not been observed and one can only speak of a "reinsurance" strategy that allows one to defend from risks through coalitions with other countries. In the early 2010s Under the influence of the growing perception of China's actions in the East China Sea as a security threat, Japan's strategy towards the PRC shows more and more signs of a transition to balancing and containment. However, the likelihood of a transition to a "double reinsurance" strategy is high, since China is seen primarily as a key economic partner, without which Japan's prosperity is impossible.
