AT A GLANCE

One week after the 2011 Tōhoku earthquake and tsunami, Japan Maritime Self-Defense Force P-3C patrol aircraft on disaster surveillance missions reported luminous orbs performing maneuvers near the disaster zone and Fukushima Daiichi nuclear plant. US Navy disaster relief personnel independently observed the same objects. The JMSDF reported the encounters through the Japan Maritime Staff Office. The Fukushima nuclear facility proximity gave the reports special sensitivity.

DECLASSIFIED DETAILS

On March 18, 2011, one week after the devastating 9.0-magnitude Tōhoku earthquake and tsunami, Japan Maritime Self-Defense Force P-3C Orion aircraft conducting aerial disaster assessment sorties over the Miyagi and Fukushima prefectures reported luminous orbs conducting maneuvers near the tsunami devastation zone and, of particular concern, in proximity to the Fukushima Daiichi nuclear power plant, which was in the midst of its catastrophic reactor meltdowns. US Navy vessels and helicopter crews participating in Operation Tomodachi disaster relief also independently observed the same objects. The JMSDF filed classified reports through the Japan Maritime Staff Office. The US Navy reports went through Pacific Fleet command. The proximity to the Fukushima nuclear event, combined with the pattern of historical UAP appearances at nuclear facilities during crises, drew significant classified intelligence attention. The encounters occurred in the most extensive joint US-Japan military operation in years.

KEY CHARACTERISTICS
  • Near Fukushima Daiichi during active nuclear meltdown — extreme sensitivity
  • JMSDF and US Navy both filed reports — joint operation
  • One week post-Tōhoku earthquake — Operation Tomodachi deployment
  • Japan Maritime Staff Office official report channel
  • Pattern: UAP near nuclear facilities during crises
  • Most extensively joint US-Japan military operation in years

Japan JSDF Radar UAP Detections — Parliamentary Disclosure

Japanese territorial airspace (multiple sectors)

In April 2023, the Japanese government disclosed to its Parliament (the Diet) that the Japan Air Self-Defense Force (JASDF) had recorded multiple unidentified aerial objects detected by radar that could not be identified as any known aircraft or drone. The disclosure followed a formal parliamentary inquiry. Japan's Ministry of Defense established new UAP reporting protocols in 2020 and the 2023 disclosure represented the first formal parliamentary acknowledgment of operational UAP detections.

Korean War UAP Intercepts — USAF Combat Reports

Korean Peninsula and Yellow Sea, Korea

US Air Force and Navy combat pilots filed dozens of formal UAP encounter reports during the Korean War. B-29 bomber crews and fighter pilots described glowing orbs and structured craft performing extreme maneuvers in combat airspace. USAF Far East Air Force (FEAF) officially investigated and filed reports with Project Blue Book at Wright-Patterson AFB. Several cases were classified SECRET and are now available through NARA.
