AT A GLANCE

Two schoolboys in Kofu City, Japan observed a disc-shaped craft land in a vineyard near their home. One boy touched the craft's leg and his arm went numb. Yamanashi Prefecture Police officially investigated and documented the case. Physical ground traces — indentations from landing struts — were found at the reported contact point. The incident became one of the most formally documented UAP landing cases in Japanese official records.

DECLASSIFIED DETAILS

On the evening of February 23, 1975, two seven-year-old boys, Masato Kawano and Katsuhiro Yamahata, were playing near a vineyard in Kofu City, Yamanashi Prefecture, Japan when they observed a reddish-orange disc approximately 5 metres in diameter descend and land on retractable strut-like legs in a vineyard. The craft had a dome on top and small windows around its midsection. When the boys approached, one — Katsuhiro — touched one of the landing legs. He immediately felt a strong numbing sensation up his arm and fell backwards. A figure approximately 4 feet tall was reportedly seen near the craft. After a moment the craft ascended silently at high speed. The boys returned home in distress; parents called the Yamanashi Prefectural Police. Officers from the Kofu Police Station responded to the vineyard and documented two circular indentations in the soil consistent with landing strut positions, spaced as described by the boys. A formal police report was filed. Katsuhiro's arm numbness was confirmed by a physician. The case was investigated by the Japan UFO Research Association and later reviewed by the Japanese Ministry of Defense's Air Staff Office. Physical evidence and police documentation made it one of the most formally recorded UAP landing cases in Japanese official records.

KEY CHARACTERISTICS

Trans-en-Provence — Physical Trace Landing, France

Trans-en-Provence, Var, France

A retired engineer observed a disc-shaped object land in his terraced garden in southern France. Physical trace evidence collected by French national police (Gendarmerie) was subsequently analyzed by GEPAN — the French government's official UAP investigation body — and found to include ground compression, scorched vegetation, and unusual biochemical changes in plant matter at the landing site. GEPAN's 1983 report remains one of the most rigorous official government UAP physical evidence analyses ever published.

Lavender farmer Maurice Masse observed a disc-shaped craft on his field with two small occupants. After his approach, one entity pointed a device at him causing temporary paralysis. The French Gendarmerie formally investigated, documenting ground traces including a concrete-hard depression where the craft landed, elevated calcium in the soil, and permanent damage to the lavender crop at the contact point.
