합리적인 수사권조정에 대한 논의의 검토-일본의 국가수사구조(검찰·경찰)와 개혁방향을 중심으로-

Japan 's security situation has remained stable throughout the world as it has undergone a period of high economic growth. The prosecutors, the police and the judiciary play a major role as the major causes. In Japan, the role of the police, the prosecution and the judiciary are closely related to each other, ranging from investigation to arrest, prosecution and trial. However, the relationship between the prosecution and the police is based on horizontal equal partnership. The police have the primary investigation authority. instead, the prosecutors have a certain range of direction and command. Japan, on the other hand, consists of a dual system of national police and local autonomous police. Local police are in charge of affairs related to people's lives. The national police are subjected to widespread incidents or to the operation of the state. The police committee system to protect political neutrality is also a feature of Japanese police. On the other hand, in Korea, as a part of criminal justice reform, the whole investigation structure is being reviewed. Specifically, discussions are under way in various fields including reform of investigation structure, the introduction of autonomous police system, and the establishment of a high-ranking civil servant investigation agency to realize the principle of check and balance between investigative agencies. However, it seems that it is not easy to integrate opinions because there are various views along with various approaches. Therefore, in - depth discussion on the whole investigation structure is required. In particular, a thorough and careful examination of the details of the investigation structure is needed. At this time, it is believed that providing historical information on the Japanese police after the war, information on the general criminal procedure in Japan, where investigation and prosecution are separated, will be a good reference for Korea at this time. This paper also includes the current structure and process of investigation in Japan, as well as recent reform directions and contents. Based on this, I would like to suggest some implications for the reform of investigation structure of Korea recently.
