Fujimori Shizuo was born in Kurume, (Fukuoka Prefecture). In 1911 he entered the Western Painting Section of the Tokyo School of Fine Arts, from which he graduated in 1916. While at the school he met Onchi Kōshirō (1891-1955) and worked with him on the print and poetry magazine Tsukuhae (Moonglow) to which he contributed 37 prints, several of which are shown below. In 1919 he took part in the first Japan Creative Print Association (Nihon Sōsaku-Hanga Kyōkai) exhibition.
Fujimori was a prolific full-time artist, a founding member of the Nihon Hanga Kyōkai in 1931, the principal editor of Shi to hanga, and a contributor to numerous Hanga magazines. He was also one of the contributors of the important series One Hundred Views of New Tokyo (Shin Tokyo hyakkei), along with Maekawa Senpan (1888-1960), Onchi Kōshirō, Takashi Henmi, Hiratsuka Un'ichi (1895-1997), Kawakami Sumio (1895-1972), Sakuichi Fukazawa and Kanenori Suwa between 1929-1932. Fujimori's landscape and figurative styles were heavily influenced by Expressionism.
