Definition. A megacity is defined by the United Nations as a metropolitan area with a total population of more than 10 million people. Some definitions also set a minimum level for population density (at least 2,000 persons/square km). A megacity can be a single metropolitan area or two or more metropolitan areas, which have grown to such an extent, that they now form one urban area.
Tokyo is a mega city. Japan is home to many densely populated cities, such as Osaka, Yokohama, and the megacity of Tokyo. Thought is sometimes divided over whether to include suburbs in the population count of cities. New York is considered a megacity.anitation, crime, and poverty are severe issues a megacity must face, and few have found sufficient ways to deal with these problems. But possibly the greatest challenge a megacity will face is the development of slums or shanty-towns along the border of the developed city.
