Fujimura was born in Hokkaidō. His grandfather was a former samurai of the Morioka Domain, and his father relocated to Hokkaidō after the Meiji Restoration as a director of the forerunner of Hokkaido Bank. Fujimura graduated from middle school in Sapporo, and then relocated to Tokyo where he attended a preparatory school for entry into Tokyo Imperial University.
Fujimura became distraught when rejected by Tamiko, the eldest daughter of Kikuchi Dairoku, in favor of Tatsukichi Minobe, whom she later married. He traveled to Kegon Falls in Nikko, a famed scenic area, and wrote his farewell poem directly on the trunk of a tree before committing suicide. His grave is at Aoyama Cemetery in Tokyo.
The story was soon sensationalized in contemporary newspapers, and was commented upon by the famed writer Natsume Sōseki, an English teacher at Fujimura's high school. Later Sōseki wrote on his death in Kusamakura.
