National security has transformed in the twenty first century, with cyberspace becoming a key conflict domain. Japan, like other nations, has adapted to these changes. In 2022, the Japanese government introduced its active cyber defense concept. The National Security Strategy of 2022 stated the government's posture for active cyber defense, which pre-emptively neutralizes adversary computers. This marked a turning point in Japan's security and defense. This strategic shift, which occurred notably between 2000 and 2022, exemplifies Japan's transition in the cyber domain. The scope of protecting cyberspace has evolved from primarily safeguarding civilian infrastructure to adopting proactive measures. This evolution is analyzed in the paper, which contrasts Japan's approach with Western nations' military-driven cyber policies. Additionally, the multifaceted challenges and opportunities arising from this paradigm shift in cyber capability development are explored. The analysis encompasses key aspects, including the policy formation, international cooperation, budgetary allocations, and the progress of organizational structures regarding the cyber domain. Furthermore, the study explores Japan's future trajectory in cyber defense, with a particular focus on its role within the 'Multi-Domain Defense Force' and the dynamics of the Japan-US alliance. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y custom: Copyright of Pacific Review is the property of Taylor & Francis Ltd and its content may not be copied or emailed to multiple sites without the copyright holder's express written permission.
