Japan has had a parliamentary UFO caucus since June 2024. The Parliamentary Group for the Study of Unidentified Anomalous Phenomena is cross-party and counts more than 80 lawmakers, including former defense ministers. It is chaired by former Defense Minister Yasukazu Hamada of the ruling Liberal Democratic Party, with Shinjiro Koizumi as secretary-general at its founding. From the start, its pitch was that UAP are a security problem: Japan should be able to detect and analyze them, and should work with the United States, which set up its own UAP office, AARO, in 2022.

In May 2025 the group handed the defense minister a proposal for a dedicated UAP office inside the ministry. It went nowhere.

On March 24, 2026, the group announced on X that it would try again, this time aiming higher. It said it would formally propose a specialized government body to oversee UAP intelligence, placed under the deputy chief cabinet secretary for crisis management, inside the prime minister’s Cabinet Secretariat rather than the Defense Ministry. A meeting to consider the proposal was set for March 30 in Tokyo.

According to UFO news sites, the group cited U.S. declassification under President Trump and an incident at the Genkai nuclear power plant, where it says there are discrepancies between the utility’s records and the police explanation. Its working assumption is that the objects are likely human-made adversary technology, not alien.

We found no mainstream report of what came of the March 30 meeting.
