Toshima ( 豊島区 , Toshima-ku ) is a special ward in the Tokyo Metropolis in Japan . It is one of the eight central wards of the Tokyo Metropolitan area. Located in the northern area of Tokyo, Toshima is bordered by the wards of Nerima , Itabashi , and Kita in the north and Nakano , Shinjuku , and Bunkyo in the south.
18-403: The ward was founded on March 15, 1947, and reached a peak resident population of 370,000 in 1965. The population has continued to decline and as of May 1, 2015, the ward had an estimated population of 298,250, with a population density of 22,920 persons per km. During the day the population swells with commuters, resulting in a daytime population of around 378,475. The total land area of Toshima
36-579: A bookstore chain, is headquartered in Toshima. Itochu corporation and Seven & I Holdings Co., Ltd. has a presence in Toshima. Taisho Pharmaceutical , a pharmaceutical company, also has its headquarters in the ward. In 1956, Asatsu Inc. established its headquarters in Mejiro, Toshima. In May 1967, the company's headquarters moved to Shinbashi , Minato. There are six Universities in Toshima. Two prestigious universities are located bordering Toshima. They are
54-569: A fast pace. Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Very densely populated cities are mostly in Asia (particularly Southeast Asia ); Africa's Lagos , Kinshasa , and Cairo ; South America's Bogotá , Lima , and São Paulo ; and Mexico City and Saint Petersburg also fall into this category. City population and especially area are, however, heavily dependent on
72-538: A high urbanization level, with an economically specialized city population drawing also on rural resources outside the area, illustrating the difference between high population density and overpopulation . Deserts have very limited potential for growing crops as there is not enough rain to support them. Thus, their population density is generally low. However, some cities in the Middle East, such as Dubai , have been increasing in population and infrastructure growth at
90-523: A little less than the land area of Puerto Rico , 8,868 square kilometres (3,424 sq mi). Although the arithmetic density is the most common way of measuring population density, several other methods have been developed to provide alternative measures of population density over a specific area. Land area This is a list of the world's countries and their dependencies by land, water, and total area, ranked by total area. The entries in this list include, but are not limited to, those in
108-560: A suburban agricultural district in the Edo period to the urban commercial center that it is today. The growth was fueled by the construction of various rail lines built in the Meiji and Taishō periods. The former Somei village, now part of Toshima, was a center of plant nurseries, and is the birthplace of the Somei Yoshino , Japan's most popular variety of sakura (cherry blossom tree). The variety
126-476: Is Ikebukuro Station , the second busiest train station in Japan. The rail lines which run through or terminate in Toshima are: Population density Population density (in agriculture : standing stock or plant density ) is a measurement of population per unit land area. It is mostly applied to humans , but sometimes to other living organisms too. It is a key geographical term. Population density
144-485: Is 13.01 km, sitting on a moderate plateau with a difference of 28 m between the ward's highest and lowest points. Approximately 47% of Toshima's land is residential, and 20% is commercial and public areas. Although Toshima is a ward, it is referred to as a city. The ward offices are located in Ikebukuro , which is also the commercial and entertainment center of Toshima. With a non-Japanese population of 19,868, or 7.42% of
162-566: Is calculated for a county , city , country , another territory or the entire world . The world's population is around 8,000,000,000 and the Earth 's total area (including land and water) is 510,000,000 km (200,000,000 sq mi). Therefore, the worldwide human population density is approximately 8,000,000,000 ÷ 510,000,000 = 16/km (41/sq mi). However, if only the Earth's land area of 150,000,000 km (58,000,000 sq mi)
180-588: Is population divided by total land area , sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are: Population density is the number of people per unit of area, usually transcribed as "per square kilometer" or square mile, and which may include or exclude, for example, areas of water or glaciers. Commonly this
198-518: Is taken into account, then human population density is 53/km (140/sq mi). This includes all continental and island land area, including Antarctica . However, if Antarctica is excluded, then population density rises to over 58 per square kilometre (150/sq mi). The European Commission's Joint Research Centre (JRC) has developed a suite of (open and free) data and tools named the Global Human Settlement Layer (GHSL) to improve

#1733085388879216-568: The ISO 3166-1 standard, which includes sovereign states and dependent territories . All 193 member states of the United Nations plus the two observer states are given a rank number. Largely unrecognised states not in ISO 3166-1 are included in the list in ranked order. The areas of such largely unrecognised states are in most cases also included in the areas of the more widely recognised states that claim
234-584: The University of Tokyo in Bunkyo and Waseda University bordering Shinjuku. Located Tokyo Metropolitan Government Board of Education operates area public high schools. Toshima is also home to a number of accredited private schools: Toshima City Board of Education (豊島区教育委員会) operates public elementary and junior high schools. Municipal junior high schools: Municipal elementary schools: Municipal kindergartens: The main hub for rail transportation in Toshima ward
252-547: The definition of "urban area" used: densities are almost invariably higher for the center only than when suburban settlements and intervening rural areas are included, as in the agglomeration or metropolitan area (the latter sometimes including neighboring cities). In comparison, based on a world population of 8 billion, the world's inhabitants, if conceptualized as a loose crowd occupying just under 1 m (10 sq ft) per person (cf. Jacobs Method ), would occupy an area of 8,000 square kilometres (3,100 sq mi)
270-472: The same territory; see the notes in the "Notes" column for each country for clarification. Not included in the list are individual country claims to parts of the continent of Antarctica or entities such as the European Union that have some degree of sovereignty but do not consider themselves to be sovereign countries or dependent territories. This list includes three measurements of area: Total area
288-545: The science for policy support to the European Commission Directorate Generals and Services and as support to the United Nations system. Several of the most densely populated territories in the world are city-states , microstates and urban dependencies . In fact, 95% of the world's population is concentrated on just 10% of the world's land. These territories have a relatively small area and
306-461: The total, Toshima is one of the most international wards in Tokyo. Of the foreign population, 56% is of Chinese descent , 20% is of Korean descent , with the rest being of primarily Filipino and European descent. Toshima was formed in 1932 by the merger of four towns, Sugamochō, Nishi-sugamochō, Takadachō, and Nagasakichō, bordered by the quickly expanding former city of Tokyo . The area evolved from
324-675: Was developed at the end of the Edo period. Toshima is run by a city assembly of 36 elected members. The current mayor is Yukio Takano, an independent backed by all major parties except the Japanese Communist Party . In April 2011, Taiga Ishikawa was elected to the Toshima assembly, becoming the first openly gay man to win an election in Japanese history.
