On 23 February 1975, two seven-year-old boys in Kofu, Japan reported a landed object and a small being. The case was investigated locally, and the object identity was never settled.

Kofu matters because it is a Japanese child-witness close-encounter case — a test of treating a young-witness account honestly, with the being unverified.
Two seven-year-old boys playing in Kofu reported two orange glowing objects, one of which landed in a nearby vineyard.
