Japanese painter Genichiro Inokuma went to America in 1955, where he switched to abstract painting. During a 20-year stay in New York, he changed his style of painting many times, being influenced by several Western painters. He produced large canvases of mainly horizontal linear composition that, although abstract, suggest city planners' blueprints, ladders, rail tracks, derricks, cranes, urban maps, industrial landscapes, mostly in single colors or black on white. He also had a phase of painting female nudes, mostly when he stayed in Japan.
Inokuma studied at the Tokyo National University of Fine Arts and Music. In 1936, Inokuma founded the Shinseisaku-ha-kyokai (New Creation Group), moving to Paris in 1938, where he was highly inspired by Henri Matisse and Pablo Picasso. When World War II broke out, Inokuma returned to Japan.
