Kazumasa Nagai was born in Osaka in 1929 and became one of the key figures in postwar Japanese graphic design. He left the sculpture department at the Tokyo National University of Fine Arts and Music in 1951, before co-founding the Nippon Design Center in 1960.
Nagai gained greater international recognition by designing the official symbols for the 1966 Sapporo Winter Olympics and the 1972 EXPO Okinawa. He also created iconic corporate logos for major companies such as Mitsubishi UFJ, Japan Railways, Nissin, and TEPCO. His vast portfolio includes thousands of posters, many of which have been exhibited in modern art museums worldwide.
Between 1960 and 1988, he received numerous prestigious awards, including the JAAC Award, Asahi Advertising Award, Mainichi Advertising Award, Yamana Award, and multiple accolades from the Tokyo ADC Show.
