Hoankyoku

Hoankyoku, written 保安局 in Chinese and Japanese and rendered in Japanese as ほあんきょく, was a secret intelligence agency created by the State of Manchuria, commonly known as Manchukuo, in December 1937. It operated in a political environment marked by armed resistance, underground political activity, and uncertainty within the Manchurian state apparatus. Anti-establishment forces included bandit groups, remnants of former military organizations, Kuomintang networks, Chinese Communist groups, and Soviet underground activity. The Kuomintang was also reported to have penetrated parts of the Manchurian bureaucracy. The agency emerged from the perceived limitations of the ordinary police. Manchukuo's police forces were ethnically diverse, which authorities regarded as a security problem because sensitive information could be difficult to contain. The proposed solution was an organization whose confidentiality would exceed that of the Japanese Tokkō, the political police, and whose existence itself would remain concealed. Hoankyoku was therefore presented administratively as a police division while functioning as a highly secret security organization. The agency maintained a close relationship with the Kwantung Army, the Japanese military formation that exercised decisive influence in Manchukuo. Members of the Kwantung Army's secret-police apparatus provided guidance, and all of Hoankyoku's heads were Japanese. Its work encompassed general investigations, domestic counterintelligence, foreign counterintelligence, the collection and handling of secret information, communications security, wireless surveillance, and specialized security research and training. A 1944 organizational description listed eight divisions and the Ryokuen Institute. Division 1 handled general affairs; Division 2 conducted investigations; Division 3 dealt with general counterintelligence; Division 4 with foreign counterintelligence; Division 5 with secret information; Division 6 with wireless counterintelligence and the detection of unauthorized radio transmissions; Division 7 with communications counterintelligence; and Division 8 with secret military or security science. The Ryokuen Institute served a training function. Hoankyoku was an institution of the wartime Manchurian state rather than a commercial consumer brand. Its historical significance lies in the way Manchukuo combined nominally state-based administration with Japanese military influence and clandestine policing. The available reference material documents its creation, purpose, relationship with the Kwantung Army, and 1944 structure, but does not establish a complete leadership list, detailed operational record, or precise date of dissolution. Because Manchukuo ceased to exist in 1945, Hoankyoku is treated as defunct.

The State of Manchuria was established in 1932 under conditions of political conflict and Japanese military influence. Authorities faced resistance from several directions, including bandit organizations, former military groupings, Kuomintang networks, Chinese Communist underground activity, and Soviet-linked underground groups. The Kuomintang was also considered to have infiltrated the Manchurian bureaucracy. The ordinary police were viewed as unsuitable for the most sensitive security work because the force included people from multiple ethnic communities. Officials feared that classified information could not be adequately protected within a conventional police structure. This led to the conception of a secret body whose confidentiality would be greater than that of the Tokkō and whose existence would itself be concealed. Hoankyoku was established in December 1937, corresponding to the fourth year of the Manchukuo-era Kokutoku reign designation. Although it was disguised as a police division, it functioned as a specialized intelligence and counterintelligence agency. It had a close institutional relationship with the Kwantung Army and received guidance from personnel associated with that army's secret police. The heads of the organization were Japanese, reflecting the strong Japanese role in its leadership and oversight. By 1944, Hoankyoku was organized into eight numbered divisions and the Ryokuen Institute. The first division managed general affairs, while the second handled investigations. The third and fourth divisions focused respectively on general and foreign counterintelligence. The fifth was responsible for secret information. The sixth monitored wireless activity and searched for unauthorized radio transmissions, and the seventh dealt with communications counterintelligence. The eighth was devoted to secret war science or related specialized security research. The Ryokuen Institute provided training for personnel. The surviving reference material does not provide a full list of directors, a detailed chronology of operations, or a separately documented dissolution order. Since Manchukuo collapsed in 1945 at the end of the Second World War, the agency is regarded as defunct. Its history is best understood within the broader history of Japanese-controlled Manchuria, wartime intelligence systems, and the use of secret policing to manage political opposition.
