Shiro Morinaga (1908-1964) studied optical illusions under the guidance of Koreshige Masuda at the Tokyo Imperial University and then went to Frankfurt a. M. to investigate perceptual problems including the factor of Ebenbreite (equal width) from 1935 to 1939 under W. Metzger. He also studied experimental aesthetics at the laboratory of E. Rubin, Copenhagen one year. He came back to Japan and worked on perception and performance of brain injured veterans at Shimofusa Sanatorium for several years. From 1949, he taught as a professor at the Chiba University until his death in 1964. He studied various perceptual problems including perceptual transparency, optical illusions, constancy, absolute judgments from the Gestalt point of view, especially theory of system of references. Many of his former students became active researchers.
