The 23 special wards (tokubetsu-ku) of Tokyo comprise the area formerly known as Tokyo City. Each ward is a local municipality with its own elected mayor and assembly, differing from an ordinary city in that certain governmental functions are handled by the Tokyo Metropolitan Government. As of September 1, 2003, the official total population of the 23 wards combined was about 8.34 million, with a population density of 13,416 persons per square kilometer.
The term "central Tokyo" today may refer to the 23 wards, the area within the Yamanote Line loop, or to the three "central wards" of Chiyoda, Chuo and Minato. While the generally-accepted center of Tokyo is the Imperial Palace, there are a number of major urban centers where business, shopping, and entertainment are concentrated.
West of the 23 wards, Tokyo consists of cities, towns and villages which enjoy the same legal status as those elsewhere in Japan. While serving a role as "bed towns" for those working in central Tokyo, some of these also have a local commercial and industrial base. Collectively, these are often known as "West Tokyo."
