Haneda Air Base UFO reports during the 1952 Japan sighting wave

Record summary

UFO literature describes a cluster of visual and radar reports around Haneda Air Base and the Tokyo area during the major international sighting wave of July 1952. The reports are potentially useful for comparing how American military installations in occupied or recently independent Asian settings recorded ambiguous aerial targets. The exact dates, observers, instruments and case-file boundaries are uncertain in model memory, and some accounts may conflate separate Japanese and U.S. reports. The episode should therefore be reconstructed from contemporary Japanese newspapers and Project Blue Book records.
