日本情报改革的安全化逻辑及其战略影响OACHSSCD

[Purpose]In recent years,Japan has launched a new round of systematic reforms to its national intelligence system.This paper aims to explain why Japan has vigorously promoted the centralization reform of its intelligence system at the current stage after long main-taining a decentralized intelligence regime,and to reveal the underlying political logic.[Method]Drawing on the securitization theory of the Copenhagen School,this paper constructs an analytical framework of"securitizing actor-existential threat-audience acceptance".Through a systematic review of Japan's official security documents,policy texts,and political discourses,it examines how the Japanese government frames threat narratives to elevate conventional intelligence coordination issues into an existential national security concern,thereby advancing the restructuring of intelligence power and institutional expansion.[Result/Conclusion]This study argues that Japan's ongoing intelligence reform represents a typical securitization process.Securitizing actors centering on the Prime Minister's Office and the Liberal Democratic Party-led ruling coalition frame traditional geopolitical risks alongside non-traditional security issues such as economic and cyber security as existential threats.Leveraging audience acceptance from domestic political circles,public opinion,and the U.S.alli-ance system,Japan has centralized intelligence authority and restructured its intelligence architecture.This process signals Japan's gradual transition from a traditionally low-securitized state to a national security state,which strengthens its capacity to implement the Indo-Pacific Strategy and deepens U.S.-Japan intelligence cooperation.Meanwhile,it risks exacerbating the security dilemma in East Asia.
