This article aims at throwing into relief views of "Nanyo" (Southeast Asia) in Japan during the Taisho period (1912-1926). There has until now been a consensus among scholars that the idea of "Nanshin" (advance to the South) existed only in the Meiji and Showa periods. In this article, the author wishes to challenge this stereotype view on the "Nanshin" theory.
It is easy to verify that "Nanyo" was discussed more often and energetically by Japanese people in the Taisho period than in the previous (Meiji) period. More importantly, the basic conditions that made possible the creation of the "Greater East Asia Co-prosperity Sphere" scheme were laid during the Taisho period. Hence, the conclusion of this essay is that the discussions made in the Taisho period were vital in paving the way for Japan's advance to the South in the Showa period, and, therefore, the significance of the Taisho period should not be underestimated.
