This report describes a one-day conference intended to advance knowledge concerning social change in Japan and the United States. Characterizing the change as one from industrial production dominance to knowledge production dominance; the conference addressed related questions such as defining post-industrial society, informational society, and "quality of life" and interpreting the consequences of those definitions. Reported here are the comments of nine speakers from America and Japan on four topics -- Environment and the Urban Situation, Information, the Economy, and Social and Governmental Organizations -- each discussed within the foregoing context but from the two differing nationalistic points of view.
