Rated both positively and negatively, Shinzō Abe has achieved a lot as prime minister. He contributed to a new perception of Japan in the international arena. During the eight years of his rule in power, his administration carried out reforms aimed at better coordination of security policy, strengthened the position of the prime minister in this field, and increased the involvement of the SDF in ensuring security. They resulted primarily from changes taking place in its security environment: the development of North Korea's missile and nuclear program, the assertive attitude of the People's Republic of China, and an increase in arms spending and the intensification of Chinese military activity in the region (around the disputed Senkaku/Diaoyu islands and in the South China Sea). The article aims to analyze the changes in the security policy introduced during the rule of Shinzō Abe in the internal aspect.
