clast is a bilingual blog created by Diamond Agency to analyze contemporary consumer and media trends in Japan. The word "clast" means literally "a fragment of rock," and we see our mission as breaking down the extremely complex systems of Japanese market culture into easily-discernible parts. At the same time, however, we also hope to break down misconceptions about the market that have buried their way into the conventional wisdom and provide a new perspective based on a multi-disciplinary analytical approach. Reaching consumers requires an accurate portrait of their world, and clast aims to draw that picture in vivid detail.

Based in Tokyo, Diamond Agency is staffed by a mix of Japanese and foreign professionals. We offer clients full-service advertising and creative services.
