On the occasion of the 1st Asian Clay Symposium in the 54th Clay Science Society Conference at Nagoya (2010), the activities of the Clay Science Society of Japan (CSSJ) for over 50 years were summarized in this review. Although the number of the CSSJ members was several hundreds and surprisingly stable from the foundation, the ratio of members of six research fields, i.e. (1) earth science, (2) resource, (3) ceramics, (4) chemistry, (5) soil and (6) civil showed a clear tendency to increase in the categories (3) and (4) while decrease in the categories (1) and (5), which means replacing of the members. This suggests that majority of the CSSJ member's interests on clays and clay minerals are shifting from understanding and characterizing of clay minerals to exploiting and using of clays as advanced materials with unique chemical and physical properties. Since such a tendency for research interest change in the CSSJ is preceding to the other clay societies in the world, we have to play more important role in leading of clay's study, especially for Asia area.
