Japan, one of the world’s most urbanized countries, offers a remarkable series of lessons for sustainable urban planning. This book draws together experts in engineering, the humanities, social sciences, and mental health to introduce Japanese experiences and compare them with international research. Rapid urbanization has damaged natural and human systems in Japan and many planners are seizing upon new technologies and scientific methods as opportunities to restructure cities. Others are focusing on the well-being of citizens and seeking to make urban society more sustainable. This book examines the tensions between sociological and technological approaches and the dichotomy between planning professionals and civil society.
