Gen Nakatani

Gen Nakatani (中谷元) is a Liberal Democratic Party member of Japan's House of Representatives, representing Kochi's 1st constituency continuously since 1990.¹² He graduated from the National Defense Academy of Japan in March 1980 and served in the Japan Ground Self-Defense Force from 1980 to 1984, retiring at the rank of First Lieutenant.¹² He served as Defense Minister under Prime Minister Koizumi from 2001 to 2002 and under Prime Minister Abe from 2014 to 2016, then was appointed to the post again by Prime Minister Ishiba in October 2024 -- making him a three-time Defense Minister.¹

  Background

Nakatani's career has been centred on national security, defence policy, and constitutional affairs. His long tenure in the House of Representatives and his three periods as Defense Minister make him one of the most experienced figures in Japanese defence politics. Japan's post-war constitutional constraints on its Self-Defense Forces and the country's proximity to airspace irregularities -- including the historically notable 1986 Japan Airlines Flight 1628 incident over Alaska -- have long shaped how Japanese defence officials approach the subject of unidentified aerial phenomena.

  The parliamentary league and the May 2025 proposal

Japan's cross-party Parliamentary League for Clarifying Unidentified Anomalous Phenomena from a National Security Perspective (超党派UFO議連) was established on 6 June 2024.³⁴ The league was chaired by former Defense Minister Yasukazu Hamada, with Shinjiro Koizumi as secretary-general and Shigeru Ishiba as supreme adviser; membership exceeded 80 Diet members drawn from ruling and opposition parties.³⁴

On 16 May 2025, members of the parliamentary league delivered a formal written proposal to Defense Minister Nakatani.⁵ The proposal called on the Ministry of Defense to establish a dedicated department for UAP data collection, investigation, and analysis -- an institution comparable to the U.S. Pentagon's All-domain Anomaly Resolution Office (AARO) -- and to disclose findings to the public and report regularly to the Diet.⁵

Nakatani responded by stating, per Nikkei reporting, that the ministry is conducting 'information collection and surveillance with constant vigilance, including for unidentifiable objects' (識別不能の物体も含めて、平素から緊張感を持って情報収集、警戒監視にあたっている) and committed to prompt disclosure of any significant new findings.⁵ This statement describes existing practice; it does not announce a new departmental structure.

  What is confirmed and what is not

No dedicated MoD UAP investigation department was formally announced by Nakatani or the Ministry of Defense following receipt of the May 2025 proposal.⁵ MoD press-conference transcripts published on mod.go.jp for May 2025 do not contain a record specifically addressing the parliamentary league proposal or announcing any new UAP office.⁶

The quote 'We will make efforts to meet the expectations of lawmakers and the public' was attributed to Nakatani in reporting that traces to Kyodo News, relayed by secondary outlets; Nakatani was also described in some of those secondary outlets as one of the parliamentary league's founding members.⁷ Neither claim has been verified against MoD press-conference transcripts, and the quote does not appear in Nikkei's reporting of the event. The founding-member characterisation is also chronologically questionable: the league was established in June 2024, four months before Nakatani became Defense Minister in October 2024.³¹ His alleged pre-ministerial membership in the league as a Diet backbencher has not been confirmed from primary Japanese-language sources reviewed here.

The characterisation of Nakatani's response as a commitment to create a new UAP office rests on wire service (Kyodo News) via secondary outlets framing rather than his verified statement. His confirmed response, as reported by Nikkei, describes existing surveillance practices and a commitment to disclosure of significant findings, not a commitment to establish new institutional machinery.⁵

  Dossier assessment

Nakatani's confirmed role in the UAP disclosure record is limited but significant: as the serving Defense Minister, he was the direct recipient of a formal parliamentary proposal calling for institutional change in how Japan handles UAP data. His verified public response acknowledged existing surveillance practices and committed to disclosure of material findings. Whether his ministry will take steps toward establishing a dedicated analytical function comparable to AARO -- as the parliamentary league proposed -- remains an open question as of mid-2026.
