The artist made his first print in 1946, the same year he joined the Bijutsu Bunka Kyokai, a group instrumental in bringing abstract and surrealist painting back to Japan after the war. In the 1960s and 1970s Tajima developed his well-known abstract style of prints made of dense rich pigments on complex surfaces formed by building the block up with various materials. His prints were inspired by the ideals of East Asian calligraphy, traditional Japanese painting structures and a sense of space influenced by Zen Buddhist beliefs. In 1963 Tajima became a member of the Nihon Hanga Kyokai, the Japanese Print Association. In 1964 his work was shown in the Tokyo Biennale as well as in international competitions. Tajima also produced landscape prints under the name of Nagai Kiyoshi.
