Urayasu (浦安市 Urayasu-shi) is a city located in Chiba Prefecture, Japan. As of December 1, 2015, the city had an estimated population of 163,258, and a population density of 9490 persons per km². The total area is 17.30 square kilometres (6.68 sq mi).
Urayasu is best known as the home of the Tokyo Disney Resort, which opened in 1983, and the headquarters of The Oriental Land Company.
The area around Urayasu was tenryo territory within Shimōsa Province controlled directly by the Tokugawa shogunate during the Edo period. Urayasu served as an important fishing village for the Edo capitol. Until the industrialization of the city it was a major center of production of nori, an edible seaweed, hamaguri, the common orient clam, and asari, the Japanese cockle. All three are important elements of the traditional Japanese diet.
Chiba Prefecture (千葉県 Chiba-ken) is a prefecture of Japan located in the Kantō region, and the Greater Tokyo Area. The sixth most populous prefecture, and 27th largest by land area, Chiba is on the east coast of Honshu and largely consists of the Bōsō Peninsula, which encloses the eastern side of Tokyo Bay. Its capital is the city of Chiba.
The name of Chiba Prefecture in Japanese is formed from two kanji characters. The first, 千, means "thousand" and the second, 葉 means "leaves". The name first appears as an ancient kuni no miyatsuko, or regional command office, as the Chiba Kuni no Miyatsuko (千葉国造). The name was adopted by a branch of the Taira clan, which moved to the area in present-day Chiba City in the late Heian period. The branch of the Taira adopted the name and became the Chiba clan, and held strong influence over the area of the prefecture until the Azuchi-Momoyama period. The name "Chiba" was chosen for the prefecture at the time its creation in 1873 by the Assembly of Prefectural Governors (地方官会議 Chihō Kankai Kaigi), an early Meiji-period body of prefectural governors that met to decide the structure of local and regional administration in Japan.
The compound word Keiyō (京葉), which refers to the Tokyo-Chiba region, is formed from the second character in Tokyo (京), and the second character in Chiba (葉), which can also be pronounced "kei" and "yō" respectively. This compound is used in terms such as the Keiyō Line, Keiyō Road, Keiyō Rinkai Railway Rinkai Main Line, and the Keiyō Industrial Zone.
The prefecture also boasts Japan's overall second-highest agricultural output. Among all the prefectures, only Hokkaidō produces more agricultural products, and Chiba leads Hokkaidō in vegetable production. Peanuts are considered a specialty product of Chiba: 78 per cent of the country's peanuts are produced in the prefecture.
Chiba Prefecture leads the nation in the production of several vegetables, including carrots; cabbage; daikon radish; negi, the ubiquitous Japanese cultivar of the Welsh onion; loquat; nashi, the Japanese cultivar of the pear, which has a two hundred-year history of cultivation in the prefecture; tomatoes; and spinach It is the nation's second largest producer of corn. Rice is also grown, and seaweed, specifically nori, is harvested in large quantities from Tokyo Bay.
The South Kantō region (南関東 Minami Kantō) is a potentially ambiguous term. Informally, it may mean the One Metropolis, Two Prefectures, or the area without Saitama Prefecture. Formally, it may mean the South Kantō Block, which is not the Greater Tokyo Area, but a proportional representation block of the national election, comprising Kanagawa, Chiba, and Yamanashi Prefectures.
In informal occasions, the term National Capital Region (首都圏 Shuto-ken) often means Greater Tokyo Area. Officially, the term refers to a much larger area, namely the whole Kantō region and Yamanashi Prefecture.
Tokyo as a metropolis includes some 394 km2
of islands (Izu Islands and Ogasawara Islands), as well as some mountainous areas to the far west (331 km2
), which are officially part of Greater Tokyo, but are wilderness or rustic areas.
At the centre of the main urban area (approximately the first 10 km from Tokyo Station) are the 23 special wards, formerly treated as a single city but now governed as separate municipalities, and containing many major commercial centres such as Shinjuku, Shibuya, Ikebukuro and Ginza. Around the 23 special wards are a multitude of suburban cities which merge seamlessly into each other to form a continuous built up area, circumnavigated by the heavily travelled Route 16 which forms a (broken) loop about 40 km from central Tokyo. Situated along the loop are the major cities of Yokohama (to the south of Tokyo), Hachiōji (to the west), Ōmiya (now part of Saitama City, to the north), and Chiba (to the east). Within the Route 16 loop, the coastline of Tokyo Bay is heavily industrialised, with the Keihin Industrial Area stretching from Tokyo down to Yokohama, and the Keiyō Industrial Zone from Tokyo eastwards to Chiba. Along the periphery of the main urban area are numerous new suburban housing developments such as the Tama New Town. The landscape is relatively flat compared to most of Japan, most of it comprising low hills.
Outside the Route 16 loop the landscape becomes more rural. To the southwest is an area known as Shōnan, which contains various cities and towns along the coast of Sagami Bay, and to the west the area is mountainous.
Many rivers run through the area, the major ones being Arakawa and Tama River.
