| Oblique Aerial View of the Center of the Tokyo Metropolitan Area from the South above Tokyo Bay | |
Alluvial lowlands and reclaimed lands facing Tokyo Bay develop along the area from the mouth of the Tama River to the lower reaches of the Ara River, sandwiched by east and west Late Pleistocene uplands. These landforms are obscured by urbanization. The population of the special wards of central Tokyo is ca. 8 million, that of Tokyo is ca. 12 million, and the total population of Tokyo and its three neighboring prefectures of Saitama, Chiba, and Kanagawa is ca. 34 million, which is equivalent to more than one-fourth of the total population of Japan. Beneath the metropolitan Tokyo area, there are three plates, unconsolidated thick sediments, and active faults, indicating the area is geologically unique and unstable. History shows that earthquakes have repeatedly occurred and sometimes caused large-scale disasters in this region. |
