Trained at the Academy of Fine Arts in Tokyo and at the Académie de la Grande Chaumière when he moved to Paris, Toshimitsu Imai always showed a particular sense of color. His paintings become abstract in contact with Michel Tapié and Informal Art, that he helped to make known in Japan. Represented by Leo Castelli in New York in 1956, he gained international success at the São Paulo Biennale in 1953 and at the Venice Biennial in 1960. Incandescent lava explosion, « Untitled » (1962-1964) is typical of his work of the early 60s. Playing with countless trails of unmixed painting, Toshimitsu Imai creates, thanks to the magic force of its composition, a real dramaturgy of color.
