Matatarō Matsumoto

Matatarō Matsumoto (松本 亦太郎, Matsumoto Matatarō; 1865–1943) was a Japanese psychologist who set up the first psychological laboratory in Japan. He has been described as "the most eminent figure in the history of psychology in Japan". He founded the Japanese Journal of Psychology and the Japanese Psychological Association.

A native of Takasaki, Matsumoto studied for undergraduate and master's degrees in Tokyo, studying under Japan's first academic psychologist, Yūjirō Motora. He earned a doctorate at Yale University under the tutelage of psychologist Edward Wheeler Scripture. Matsumoto taught at the Tokyo Higher Normal School before he set up Japan's second psychology laboratory at Kyoto University. He then took over the psychology program at Tokyo Imperial University after Motora died.
