Yanaihara Tadao 矢内原 忠雄


Yanaihara Tadao was an Economist and Doctor of Economics of the Taishô and Showa periods.


Yanaihara Tadao was born on 27 January 1893 in Japan.


He was a student in the First High School. Then studied at Tokyo Imperial University. After a period of study in Europe and America, he became a full professor in 1923, lecturing on colonial policy.


After graduating from Tokyo University, he worked for a time for a mining company, Sumitomo Besshi Kozan, but in 1920 became an assistant professor in the economics department of Tokyo University.

In 1937, shortly after the outbreak of war between China and Japan, he published an article entitled Kokka no riso (“Ideals of the State”) in the magazine Chuo Koron, which was attacked by the militarists and right-wing elements because of its antiwar sentiment. The incident led to his resignation from Tokyo University. Throughout the war period, he continued to publish a private magazine entitled Kashin, which embodied Christian ideals, and opened a private school in his home on Saturdays to teach pacificist principles based upon religious faith. With the conclusion of the war in 1945, he returned to his teaching position at Tokyo University. In 1949 he became a member of the Japan Academy.

At Tokyo University he served as head of the Social Science Institute, head of the economics department, and head of the department of liberal arts, and in 1951 succeeded Nambara Shigeru as president of the university. He retired in 1957 to become a professor emeritus. During these postwar years in Tokyo University he worked consistently to guard the principles of academic freedom.


  • In 1929 he published a work entitled Teikohushugi-ka no Taiwan ("Taiwan under Imperialism”) that was translated into Chinese and Russian.


At school he came under the influence of such Christian intellectual leaders as Uchimura Kanzo and Nitobe Inazô. At the University he was also influenced in his thinking by Nitobe’s views on colonial policy and Yoshino Sakuzo’s lectures on political history.
