In 1972 Fujimura begun to study archeology and look for prehistoric artifacts. At the time he was working for a manufacturing company. He established his reputation as a leading amateurs archeologist in Japan when he made a major discovery in 1981. By stratum, it was dated as much as 40.000 years old and his career really begun.
Over the years he worked in 180 archeological digs all around Japan and always seemed to find something important and increasingly older. More superstitious would talk about his "divine hands". His work became basis of numerous textbooks and research of other archeologists. His reputation kept the would-be critics silent. He gained a position as a deputy director in Tohoku Paleolithic Institute.
In October 23, 2002 Fujimura and his team announced that they had made an important find in Kamitakamori site near the town of Tsukidate in Miyagi Prefecture. They were dated 570.000 years old.
However, in November 5, newspaper Mainichi Shimbun published pictures of Fujimura digging holes and burying the artifacts his team had later found. The pictures had been taken one day before the find had been announced.
Fujimura confessed the same day in a press conference. He said that he had wanted to be known as the person who would have found the earliest stoneware in Japan. He had planted the artifacts from his own collection to strata that would have indicated earlier dates. In Kamitamakori he had planted 61 of 65 artifacts and earlier all of the stonework in Soshin Fudozaka site in Hokkaido. He claimed these were the only times he had planted artifacts. He was immediate dismissed from his position in Tohoku institute.
All of Fujimura's work immediately fell under suspicion - and it also affected the research of many other archeologists in Japan and elsewhere, based on his findings. Professor Mitsuo Kagawa of the Beppu University hanged himself. Publishers of archeology textbooks had to change everything. Most of Fujimura's other findings have been later proven to be forgeries.
