In 1972 Fujimura began to study archaeology and to look for Paleolithic artifacts during his holidays. Within the few years to follow, he rose to fame among amateur and academic archaeologists in Sendai by which he was appointed the head of the NGO group, "Sekki Bunka Kenkyukai"("石器文化硏究会", literally translated to "stone tool culture research association") in 1975. Fujimura discovered and excavated many Paleolithic stone artifacts in Miyagi prefecture, such as at "Zazaragi site" in 1981, "Nakamine C site" in 1983 and "Babadan A site" in 1984. From a cross-dating investigation of the stratum these stone tools were estimated to be about 50,000 years old.
