Abstract: In recent years, Japan has proposed the “three pillars” of its foreign propaganda strategy and implemented them in the field of territorial propaganda, actively promoting the reform of its territorial propaganda mechanism. It has successively set up a “Minister in Charge of Territorial Integrity” in the cabinet, established an “Office of Policy Planning and Coordination on Territory and Sovereignty”, established a “Symposium of experts on internal and external communication of territorial sovereignty”, etc. At the same time, the Japanese government attaches great importance to the diversified expansion of its territorial claims promotion methods. For example, in addition to continuing to focus on using traditional media such as newspapers and radio for promotion, it actively utilizes new media channels such as government official websites and international social networking sites, and emphasizes the use of diversified promotion methods such as videos, anime, and promotional posters in the promotion process. In addition, the Japanese government has also taken measures to strengthen publicity, such as setting up a “National Museum of Territory and Sovereignty” specifically for regular propaganda activities, mandatory revision of domestic primary and secondary school textbooks, and implementation of regular public opinion surveys on territorial issues, in an attempt to gain a favorable position in public opinion and legal battles related to territorial disputes. While further expanding the way of propaganda of territorial claims, China should pay more attention to refuting the wrong views in the propaganda of Japanese territorial claims from the perspective of international law, and further strengthen the “discourse construction” of the ownership of the Diaoyu Islands in the domestic and foreign discourse environment, so as to better safeguard Chinas territorial sovereignty.

Key words: Japanese government, territorial claims, propaganda system, diversified mode, international law
