OVERVIEW OF TOKYO

TOKYO'S GEOGRAPHY, HISTORY AND POPULATION

As of October 1, 2003 the population of Tokyo was estimated to be 12.369 million, or about 10% of Japan's total population, the largest population of any of the 47 prefectures.

Tokyo's area, 2,187 square kilometers or 0.6% of the total area of Japan, makes it the third smallest of Japan's 47 prefectures. The population density is 5,655 persons per square kilometer, making Tokyo the most densely populated prefecture in Japan.

The 23 special-ward area is home to 8.34 million persons, the Tama area 4.002 million, and the Islands 27,000. Tokyo has 5.697 million households, with an average 2.17 persons per household. The registered number of foreign residents reached 354,000 as of October 1, 2003, some 1.3 times more than the total figure ten years earlier.

Population Movement

The population movement between Tokyo and other prefectures in 2002 showed 443,000 persons moving into Tokyo while 370,000 persons moved out, a total movement of 813,000 persons for a net population increase of 73,000 persons. Since 1967 there was a prevailing trend of depopulation, with only 1985 an exception, until 1997, when there was a net population increase for the first time in twelve years. 2002 again showed a net increase.

Looking at the total movement between Tokyo and the three adjacent prefectures (Saitama, Chiba and Kanagawa prefectures), 204,000 people came into Tokyo with 195,000 moving out, a total movement of 399,000 persons or 49.1% of the total, for a net population increase of 9,000 persons.

During 2002 there were 100,000 births and 85,000 deaths, a net increase of 15,000. The net increase peaked in 1968 and has been declining yearly.

Composition of Population by Age

According to the January 1, 2003 Basic Registry of Residents, 11.996 million people were registered as residents of Tokyo. This number was divided into three age categories: juveniles (ages 0-14) at 1.433 million; the working age population (ages 15-64) at 8.507 million; and the aged population (65 years old and over) at 2.057 million. These figures are 11.9%, 70.9% and 17.1% respectively of the overall population.

The ratio of aged persons exceeded the United Nations standard for an "aging country" of 7% in 1978, and the pace of increase has been accelerating since then, exceeding the "aged society" standard of 14% in 1998.

Labor Force

As of October 1, 2000, the population aged 15 years and older was 10.596 million persons, of whom 6.158 million were employed and 312,000 were fully unemployed within a total working population of 6.47 million persons.

Population Composition by Industry
According to the National Census of 2000, when working people were separated into three industrial groups, 27,000 persons (0.4%) were employed in the primary industries of agriculture, forestry and fisheries; 1.383 million (22.5%) in secondary industries (mining, construction and manufacturing); and 4.573 million (74.2%) in tertiary industries (commerce, transportation, communication and services).

Population Composition by Occupation
According to the National Census of 2000, when working people were separated into four employment groups, 28,000 persons (0.5%) were employed in agriculture, forestry and fisheries; 1.481 million (24.0%) in manufacturing- and transportation-related occupations; 1.798 million (29.2%) in sales and services; and 2.851 million (46.3%) in clerical, technical and management occupations.

Daytime and Nighttime Population

The National Census in 2000 lists the daytime population of Tokyo as 14.667 million people, which was 2.650 million more than the nighttime population figure of 12.017 million. The difference is caused by the population of commuting workers and students, constituting a daytime influx from the three neighboring prefectures of Saitama, Chiba and Kanagawa.

The daytime population, broken down by area, shows 11.125 million in the 23 special-ward area, 3.154 million in the Tama area and 28,000 persons in the islands; the 23 special-ward figure is noticeably higher. Remarkably, the three Tokyo core wards - Chiyoda, Chuo and Minato - have a nighttime population of 268,000 persons and a daytime 2.341 million, so that their daytime population is more than eight times the nighttime population.

Changes since 1965 show that in the period up to 2000, the nighttime population increased to 1.15 million (10.6%), whereas the daytime population leaped to 2.92 million (24.8%), creating a large imbalance.
