Summary

In May 2026, the Trump administration released approximately 160 previously classified UAP files. The disclosures included incidents across the Western Pacific, with several cases linked to activity near Japan. The most notable Japan-linked incident is a 2024 U.S. Indo-Pacific Command report describing a metallic, football-shaped object over the East China Sea. The object exhibited non-ballistic movement, could not be identified, and was added to AARO's Active Archive. At a May 11, 2026 press conference, Japan’s Chief Cabinet Secretary Minoru Kihara stated that they are analyzing the released files and maintaining close coordination with the United States. He added that decisions on releasing Japan’s own UAP files would be made on a case-by-case basis to protect intelligence-gathering capabilities. On the legislative front, the cross-party Parliamentary UAP League submitted four Cabinet recommendations: dedicated UAP data analysis, interagency coordination, public communication protocols, and formalized U.S.-Japan intelligence sharing. The group is also preparing for the formal founding of the 'Unidentified Aerial Phenomena Clarification League' parliamentary body, scheduled for June 2026.

 

Detailed Report

1. Japan-Specific Content in the US-Released Files

On May 8, 2026, the Pentagon released approximately 160 UAP files, including several incidents in the Western Pacific [for broader context on the US file release process and the PURSUE program, see the previous report here]. Among these, the most prominent Japan-linked case is a 2024 report from the U.S. Indo-Pacific Command describing a metallic, football-shaped object observed near Japan in the East China Sea. The object exhibited non-ballistic movement and was classified as unresolved due to insufficient data. This case was added to the All-domain Anomaly Resolution Office’s (AARO) Active Archive.

The files also reference broader U.S. military UAP activity in the region, with over 100 reports from U.S. assets operating in East Asian seas. While many were resolved as balloons or unmanned aerial systems, others—including the football-shaped object—remain unexplained. Notably, the files do not detail any direct encounters by Japanese Self-Defense Forces (JSDF), but they do highlight ongoing coordination and information sharing between U.S. and Japanese authorities regarding UAP incidents.

 

2. Japanese Government Responses

Chief Cabinet Secretary Minoru Kihara addressed the U.S. file releases during a press conference on May 11, 2026. He confirmed that Japan is actively analyzing the files and maintaining close coordination with the United States and other countries on UAP-related incidents. Kihara emphasized that decisions on releasing Japan’s own UAP files would be made on a case-by-case basis, taking into account the risk of exposing intelligence-gathering capabilities. Parliamentary interest in UAPs remains active, with cross-party groups renewing calls for the establishment of a dedicated office within the Ministry of Defense to investigate UAPs. The formal founding of the “Unidentified Aerial Phenomena Clarification League” parliamentary group is scheduled for June 2026.

 

3. Parliamentary Action and Policy Recommendations

Japan’s cross-party Parliamentary UAP League, established in late 2024, has become the principal legislative body addressing UAP-related issues. Comprising over 40 members from multiple parties, the League includes senior figures with backgrounds in defense and intelligence. In March 2026, the League finalized a draft set of recommendations for the Cabinet, structured around four key pillars:

·      Enhanced UAP Data Analysis: Proposal for a dedicated UAP Analysis Center within the Ministry of Defense to aggregate and analyze data from military and civilian sources.

·      Interagency Cooperation: Recommendation to establish an Interagency UAP Task Force, chaired by the Cabinet Office, to coordinate operational responses and standardize reporting.

·      Public Communication Guidelines: Development of official protocols for government spokespersons and a public information portal to ensure clear, consistent communication about UAP incidents.

·      U.S.-Japan Intelligence Sharing: Call for formalizing and deepening bilateral intelligence-sharing arrangements with the United States, building on the 2023 framework.

 

Conclusion

Japan’s response to the Trump administration’s May 2026 UFO/UAP file releases has been measured and security-focused. Government officials have confirmed ongoing analysis and close coordination with the United States, while the Parliamentary UAP League has intensified its efforts to establish a robust national framework for UAP analysis and response.
