In 2022, affected by the accelerated spread of the variant strain of Omicron and multiple factors, the epidemic situation in Japan will be tight throughout the year, prices will rise sharply, and the economy and people's livelihood will be in a difficult situation. Faced with the dual pressures of epidemic and rising prices, the Japanese people expect the government to introduce effective countermeasures in policy and legislation in a timely manner. However, from the opinion poll results and the cabinet support rate, the Japanese people are not satisfied with the government's response. However, in sharp contrast to the lack of policy and legislation in the field of economy and people's livelihood, the Japanese government deliberately played up the crisis and threat at the time of the conflict between Russia and Ukraine, looking for excuses to amend the Constitution and strengthening legislation in the field of security. The "Three Security Documents" raised concerns that in 2022, the Kenxiong Kisada government will make unprecedented efforts to adjust the national security strategy document, which has aroused great concern from the international community, especially regional countries. On December 16, Japan introduced three newly revised security documents, namely, the National Security Strategy, the National Defense Strategy and the Defense Force Readiness Plan, in the form of a cabinet resolution. The security document clearly states that Japan will develop a "counterattack capability" and significantly increase defense expenditure to 2% of GDP. Analysts believe that the Japanese government has made unprecedented efforts to adjust and modify the national security strategy document, which is the first time since the war, marking a major change in Japan's "exclusive defense" policy. Once the document was exposed, the voice of opposition at home and abroad emerged. Analysts pointed out that Japan's principle of "exclusive defense" may undergo significant changes in the coming years, and the security and stability situation in East Asia will be seriously undermined. As we all know, since the war, the development of Japan's defense forces has been constrained by the existence of a peaceful constitution. In accordance with the spirit of the peaceful constitution, Japan only maintains a minimum of self-defence armed forces. Japan adheres to the principle of "exclusive defense" and does not develop offensive armed forces. However, the "counterattack capability" stipulated in the new security document allows Japan to develop standoff attack capabilities such as medium - and long-range cruise missiles and launch direct attacks against enemy bases and other targets. Moreover, the so-called "counterattack capability" also makes it possible for Japan to launch an active attack without being directly attacked. According to the analysis of Japanese media, Japan can, according to the new security law, use the "counterattack capability" without direct attack on the grounds of exercising the right of collective self-defence. For example, when the US military is attacked, Japan can provide support to the US military and take the initiative to attack the other side, which in fact gives Japan the right to launch a preemptive strike. Japanese security experts pointed out that the new security document has broken through the traditional meaning of "exclusive defense", marking a major shift in Japan's defense policy after the war. Since this year, Japan has intensively introduced a number of measures to strengthen the Japan US military alliance, strengthen Japan Australia defense cooperation, close Japan NATO coordination, take neighboring countries as imaginary enemies, actively build a quadrilateral mechanism, an Indian Pacific economic framework, and seek to participate in small circles such as the Five Eye Alliance and the trilateral security partnership between the United States, Britain and Australia. In addition, Japanese politicians also dragged the Russian Ukrainian conflict into the East Asian situation, advocated nuclear sharing, and intensively carried out joint military exercises and military training of various scales with countries outside the region in the Indian Pacific region. Even in the economic field, security has become the most important issue in Japan
