In 2022，Japan’s domestic affairs and diplomacy faced the impact of multiple factors. The continuous spread of the COVID-19 epidemic，the assassination of Abe，and the rapid depreciation of the Japanese Yen triggered Japan’s domestic political，economic，and social turmoil. The support rate of the Kishida cabinet repeatedly dropped below “dangerous waters.” The outbreak of the Russia-Uzbekistan conflict seriously undermined the Japan-Russia policy implemented during the Abe administration and pushed Japan-Russia relations to the brink of collapse. At a time of domestic and foreign difficulties，Kishida used active shuttle diplomacy to regain the approval of Japanese voters. On the one hand，he actively strengthened the Japan-US alliance，accelerated the process of Japan-US military “integration”，and on the other hand，deepened Japan’s relationship with Europe，India，and Southeast Asia. The relationship between countries promoted the development of Japan-UK，Japan-Germany，and Japan-France relations in the direction of “alliance” and won over NATO to actively intervene in Asia-Pacific affairs. Kishida’s diplomatic aggressiveness not only won a more favorable international environment for Japan but also curbed the unilateral decline in domestic support. Meanwhile，Kishida took advantage of the turbulent international situation and the deteriorating surrounding geographical environment to reshape and strengthen the security awareness of the Japanese nationals and cleared the obstacles of public opinion for the smooth implementation of the “Three Security Policy Documents.” The release of the “Three Security Policy Documents” is a phased achievement of Japan breaking through the shackles of the post-war peace constitution and seeking a “normal country.” The transition of the defense policy from adhering to “exclusive defense” to building a “counterattack capability” will not only severely impact postwar Japan’s pacifist path but also accelerate the disintegration of the “Peace Constitution”，at the same time，it will also shake the foundation of the security order in the Asia-Pacific region and the development of China-Japan relations，which will have a far-reaching impact. 2022 is the 45th anniversary of the signing of the Sino-Japanese Treaty of Peace and Friendship. China and Japan should uphold the spirit of the treaty，insist on using peaceful means to resolve differences between the two countries，ease the increasingly acute structural conflicts between the two countries，and promote the return of China-Japan relations to on track.
