In English, it calls itself Toshima City. Toshima is one of the eight central wards of the Tokyo Metropolitan area, including Chiyoda, Minato, Shibuya, Chuo, Shinjuku, Taito, and Bunkyo surrounding the Imperial Palace. Located in the northern area of Tokyo, Toshima is bordered by the wards of Nerima, Itabashi, and Kita wards, in the north, and Shinjuku and Bunkyo in the south. 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 km². During the day the population swells with commuters, resulting in a daytime population of around 378,475. The total land area of Toshima is 13.01 km², 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 refers to itself 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 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. ==History== 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 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, is the birthplace of the ''Somei Yoshino'', Japan's most popular variety of sakura (cherry blossom tree). The variety was developed at the end of the Edo period. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Toshima」の詳細全文を読む スポンサード リンク
