As recently as 2018, the Cabinet Office stated that it had 'not considered in any specific manner what will be done should a UFO be spotted.'[^1]\n\nThat position changed on April 27, 2020, when the U.S. Department of Defense officially declassified and released three Navy pilot videos -- FLIR1, GIMBAL, and GO FAST -- showing encounters with unidentified aerial phenomena.[^2] The following day, April 28, 2020, Defense Minister Taro Kono directed the Self-Defense Forces to establish standardized procedures for encountering and recording unidentified objects, announced at a Ministry of Defense press conference.[^3] Kono was candid about his personal skepticism: 'To be honest, I don't believe in UFOs,' he stated, while framing the measure as a national-security precaution against modern drone technology and other unidentifiable airborne threats.[^3]\n\n## Guam Meeting and Bilateral Context\n\nAt the end of August 2020, Kono met U.S. Defense Secretary Mark Esper in Guam, where the two exchanged views on UAP phenomena as a potential area of bilateral security cooperation.[^4] Secondary sources have described this meeting as producing an agreement for SDF and U.S. Forces to cooperate on UAP reporting, though this characterization has not been independently confirmed in publicly available primary MoD or DoD documents beyond Kono's general reference to the Guam discussions.[^4] Some secondary aggregators have also framed the SDF protocol as being 'modeled on' the U.S. Navy's 2019 UAP reporting procedures; the primary MoD press conference transcripts do not use this framing explicitly.[^5]\n\n## The September 2020 Protocol\n\nOn September 14, 2020, the MoD formally issued the written UAP reporting directive to the SDF.[^6] At a press conference the following day, Kono confirmed the protocol and elaborated on its scope.[^7] Under the directive, SDF personnel are required to: (1) report sightings comprehensively; (2) make efforts to photograph or otherwise record encounters when possible; (3) conduct necessary analysis of recorded information. The directive applies across all military operations, not only air-defense patrols.[^7]\n\nKono stated at the September 15 press conference that the MoD had no prior records of SDF encounters with unidentified objects: 'There are no such encounter records from the past.'[^7] He continued to frame the protocol around 'unidentifiable objects' (a translation of the Japanese term he used, 識別不能の物体) rather than extraterrestrial phenomena, with drone technology cited as the primary concern.[^7]\n\n## Disputed Claims\n\nThe [1986 Japan Airlines Flight 1628 incident](/events/1986-japan-airlines-flight-1628), in which a JAL cargo crew reported gigantic lights pacing their 747 near Fairbanks and U.S. military radar detected targets, remains the most prominent Japanese aviation UAP encounter on record prior to the 2020 protocol -- though it occurred over U.S. airspace and involved civilian, not SDF, personnel.\n\n## Significance\n\nThe September 2020 protocol marked Japan's first formal, government-issued procedure for military UAP encounters. It did not establish a dedicated analytical office or a standing interagency review body; the MoD has not publicly confirmed the creation of any such structure. The protocol's significance lies in its codification of a reporting chain where none had previously existed, and in the degree to which it mirrored a broader international shift toward treating UAP as a legitimate defense-surveillance concern rather than a subject to be officially ignored.\n\n## References\n\n[^1]: Interesting Engineering: Japan's Defense Minister Reveals UFO-Hunting Protocol https://interestingengineering.com/innovation/japans-defense-minister-reveals-ufo-hunting-protocol\n\n[^2]: The Diplomat: Japan's Defense Ministry Launches Protocol for UFO Sightings https://thediplomat.com/2020/09/japans-defense-ministry-launches-protocol-for-ufo-sightings/\n\n[^3]: Ministry of Defense (Japan): Press Conference, April 28, 2020 https://www.mod.go.jp/j/press/kisha/2020/0428a.html\n\n[^4]: UAP Scientific Research Blog: Japan and UAP https://ufos-scientificresearch.blogspot.com/2020/09/japan-and-uap.html\n\n[^5]: Sandboxx: Japan follows US Navy lead, establishes UFO reporting procedures https://www.sandboxx.us/news/japan-follows-us-navy-lead-establishes-ufo-reporting-procedures/\n\n[^6]: Japan Times: Japanese Defense Ministry unveils protocol for encountering UFOs https://www.japantimes.co.jp/news/2020/09/14/national/japan-defense-ministry-ufo/\n\n[^7]: Ministry of Defense (Japan): Press Conference, September 15, 2020 https://www.mod.go.jp/j/press/kisha/2020/0915a.html","readingTime":"4 min read"},"relatedRecords":[{"ref":{"type":"updates","slug":"2026-japan-uap-and-historical-expansion","title":"Japan UAP investigation, 2026 executive actions, and historical expansion","url":"https://disclosdex.com/updates/2026-japan-uap-and-historical-expansion"},"direction":"inbound","weight":1},{"ref":{"type":"events","slug":"1986-japan-airlines-flight-1628","title":"Japan Airlines Flight 1628","url":"https://disclosdex.com/events/1986-japan-airlines-flight-1628"},"direction":"outbound","weight":1}],"citation":{"canonicalUrl":"https://disclosdex.com/programs/2020-japan-sdf-uap-reporting-protocol","title":"Japan SDF UAP Reporting Protocol","publisher":"Disclosdex","retrievedFrom":"https://disclosdex.com/api/v1/programs/2020-japan-sdf-uap-reporting-protocol","license":"CC-BY-4.0"}}
