JA showcases contemporary Japanese architecture with in-depth commentary on the theoretical history and context of the projects. It is organized with an emphasis on developments originating in Japan. The magazine surveys the country's diverse, ever-changing architectural scene, identifies important trends to convey to a wider audience outside Japan, takes up current, compelling issues and considers the latest architectural trends.
JA47 is devoted to building materials and the process of design. The materials selected by a designer profoundly affect the outcome of his design labor, as does the actual design process, which is itself shaped by the character of those materials.
