This is a list of in Japan by population as defined by the Statistics Bureau of Japan (SBJ) and the Center for Spatial Information Service of the University of Tokyo. The region containing most of the people in Japan between Tokyo and Fukuoka is often called the Taiheiyà  Belt.
The Statistics Bureau of Japan (SBJ) defines a metropolitan area as one or more central cities and its associated outlying municipalities. To qualify as an outlying municipality, the municipality must have at least 1.5% of its resident population aged 15 and above commuting to school or work into one of the central cities. To qualify as a central city, a city must either be a designated city of any population or a non-designated city with a city proper population of at least 500,000. Metropolitan areas of designated cities are defined as "major metropolitan areas" (大é½å¸ÂÃ¥ÂÂ) while those of non-designated cities are simply "metropolitan areas" (é½å¸ÂÃ¥ÂÂ). If multiple central cities are close enough such that their outlying cities overlap, they are combined and a single metropolitan area is defined rather than independently.
