The central cities of the major metropolitan areas a Ku-area of Tokyo-to and the cities designated by the Cabinet Order. In case that two or more central cities are located closely each other, the major metropolitan areas are not established separately but chained together.
A city, town or village is considered as composing the surrounding cities, towns and villages when it satisfies the following condition:i) The number of resident workers and students 15 years of age and over commuting to the central cities is 1.5 percent or more of its total resident population, and ii) The area is contiguous to the central cities or to one defined as the surrounding area. In case that the administrative unit area, where under 1.5 percent of the resident population commute to the central cities, is entirely enclosed by the areas defined as surrounding area, it is also regarded as a surrounding area.
