The early Showa period is a very important era to analyze a study on the history of French sociology in Japan. This is largely because of the fact that Durkheim's, Durkheimien's, and anti-Durkheimien's sociology, for example, the international school created by Worms, were imported actively into Japan from France in that time. There was an important journal, Shakaigakuto, which introduced those French sociologies actively in this period. Shakaigakuto were published eighteen volumes between 1927-44, and made a great contribution to produce Japanese French sociology researchers and a lot of achievements of study on French sociology. The purpose of this paper is to resolve the study process of French sociology in Japan in the early Showa period by analyzing the results appeared in Shakaigakuto. In addition, this paper enables to clarify that French sociology after Durkheim and the period between two wars was not the winter age of French sociology.
