As a spatial organization form of urban functional area, metropolitan area is the product of urbanization at a certain stage. Taking the Tokyo Metropolitan Area as a case study area and based on the index of densely inhabited district (DID), population net immigration rate, and industrial location quotient and spatial Gini coefficient, this study systematically reviewed the evolution of population distribution, population migration patterns, industrial structure transformation, and spatial reorganization since the 1960s in the region. The conclusions are as follows: First, the population distribution in the Tokyo Metropolitan Area has gradually changed from "isolated concentration" to "spreading diffusion", but the core radiation range is still within the radius of 50 km. According to the index of DID, the metropolitan area of Tokyo is characterized by large-scale and high-density population concentration, and the trend of concentration continues to be strong. Second, population inflow of three metropolitan areas in Japan changed from simultaneous growth to differentiation, and the Tokyo Metropolitan Area has always shown a strong trend of population agglomeration, with characteristics of unipolar concentration. Internally, suburbanization has basically ended, and a return to the centers is obvious. Third, the proportion of tertiary industry continues to rise, the proportion of secondary industry declines significantly, and the primary industry gradually shrinks. Although the proportion of the secondary industry has gradually declined, its status as an important production area of the national economy has not changed. Finally, from the center to the periphery, the tertiary industry, the secondary industry, and the primary industry are distributed in turn. The industrial structure adjustment and spatial reorganization in the metropolitan area happened at the same time and from the center to the periphery the value chain of industries changes from high to low. The advanced producer services and urban industries are concentrated in central areas, while technology-intensive heavy industries are located in peripheral areas.

Key words: Tokyo Metropolitan Area, population distribution, population migration, industrial evolution
