(1911-1984) Kiyoshi Nagai is maybe better known under the name of Hiroyuki Tajima (see Modern Japanese Prints by Frances Blakemore).
The artist was born in Tokyo and had studied Western painting at the Tokyo School of Fine Arts. He started with woodblock prints in 1946. Kiyoshi Nagai used the name Hiroyuki Tajima for his more abstract, modern prints and Kiyoshi Nagai for figurative landscape prints.
His usual edition size was 50. He took part in the International Tokyo Print Biennale and was a member of the Japanese Print Association (JPA).
