A very large urban agglomeration with a population exceeding 10 million inhabitants is identified as a prominent feature in urban geography. These expansive urban centers often exhibit complex social, economic, and environmental dynamics. A prime example is Tokyo, a sprawling metropolis that serves as a major global economic hub and demonstrates intricate systems of transportation, housing, and governance necessitated by its substantial population density.
The rise of these substantial urban areas presents both opportunities and challenges. Economically, they concentrate significant economic activity, fostering innovation and attracting investment. Socially, they offer diverse cultural experiences and opportunities for advancement. However, such immense concentrations of people also generate pressures related to infrastructure, resource management, and social equity. Historically, the growth of these large cities reflects broader trends of urbanization driven by factors such as industrialization, migration, and globalization.
