Public Security Intelligence Agency Publishes 2026 Annual Report, Including Trends Among Far-Left Militant Groups
This article organizes publicly available information into a single account. Where it describes an arrest or an ongoing investigation, that reflects only one stage of criminal procedure and does not mean guilt has been established (the presumption of innocence applies). We will update this article as new information becomes available, including the outcome of prosecution, non-prosecution, or trial. This article is not intended to unfairly disparage any individual, group, nationality, ethnicity, or belief, and aims to provide objective, fact-based information.
On December 24, 2025, the Public Security Intelligence Agency published the 2026 (Reiwa 8) edition of its annual report, "Review and Outlook of Domestic and International Situations," summarizing conditions in 2025 (Reiwa 7) and offering an outlook for 2026 (Reiwa 8). In addition to international affairs, the report also organizes trends in domestic public security threats.
The report is believed to also address trends among so-called far-left militant groups, including Chukaku-ha and Kakumaru-ha. However, the main text is a lengthy 15.2MB PDF document, and identifying and summarizing the sections relevant to Chukaku-ha would require a separate, detailed review of the text.
The publication date was December 24, 2025, which on the calendar precedes 2026, but because it is designated the "Reiwa 8 edition" and deals with the outlook for conditions in 2026, it can be used as a primary source for this site's articles related to Chukaku-ha.
The Public Security Intelligence Agency is a government body that, under the Subversive Activities Prevention Act and the Act on the Control of Organizations Which Have Committed Acts of Indiscriminate Mass Murder, continuously investigates and publishes information on far-left militant groups and other designated organizations. The annual report "Review and Outlook of Domestic and International Situations" has value as a primary source that is also referenced by researchers and news organizations, covering both international affairs and domestic public security issues comprehensively.
Among incidents believed to have involved Chukaku-ha, a clash with a right-wing organization at a base protest in Okinawa (related coverage) was also reported in 2026.
