This book examines Tokyo’s changes, current challenges, and future trends through a new kind of regional geography and serves as an important source of comprehensive information about the past, present, and future perspectives of Tokyo as a global city. Regional geography relies on two main approaches. The traditional one addresses each geographical element of a region individually and in depth, in a descriptive and static manner. The other focuses on a region’s specific phenomena and realities as a starting point and proceeds to identify the region’s constituent elements and their interactions, which it records and explains in a systematic and dynamic manner. The present volume, unlike its predecessors, relies on the dynamic approach and endeavors to offer a fresh view of Tokyo’s new and diverse geographical realities, analyzed in a holistic, systematic manner allowing identification of its specific features.
