Japanese Paleolithic Hoax
Amateur archaeologist Fujimura Shinichi stunned the world with his discoveries of lower and middle Paleolithic artifacts in Japan, a region most experts believed would be unlikely to harbor such finds. It turns out the experts were right.
Under great personal pressure to succeed in his field of study, Shinichi faked all of his discoveries. An expose published in 2000 revealed that Shinichi dug holes and hid archaeological items from other surveys to be discovered later. One important clue to the hoax was that Shinichi discovered some of the items more than once.
