Located near the centre of the Japanese main island of Honshu, Aichi Prefecture faces the Ise and Mikawa Bays to the south and borders Shizuoka Prefecture to the east, Nagano Prefecture to the northeast, Gifu Prefecture to the north, and Mie Prefecture to the west. It measures 106 km (66 mi) east to west and 94 km (58 mi) south to north and forms a major portion of the Nōbi Plain. With an area of 5,172.48 square kilometres (1,997.11 sq mi) it accounts for approximately 1.36% of the total surface area of Japan. The highest spot is Chausuyama at 1,415 m (4,642 ft) above sea level.

The western part of the prefecture is dominated by Nagoya, Japan's third largest city, and its suburbs, while the eastern part is less densely populated but still contains several major industrial centres. Due to its robust economy, for the period from October 2005 to October 2006, Aichi was the fastest growing prefecture in terms of population, beating Tokyo, at 7.4% and around with after Saitama Prefecture.

As of 1 April 2012, 23% of the total land area of the prefecture was designated as Natural Parks, namely the Aichi Kōgen, Hida-Kisogawa, Mikawa Wan, and Tenryū-Okumikawa Quasi-National Parks along with seven Prefectural Natural Parks.[6]

History

[edit]

Originally, the region was divided into two provinces of Owari and Mikawa.[5]: 780  After the Meiji Restoration, Owari and Mikawa were united into a single entity. In 1871, after the abolition of the han system, Owari, with the exception of the Chita Peninsula, was established as Nagoya Prefecture, while Mikawa combined with the Chita Peninsula and formed Nukata Prefecture. Nagoya Prefecture was renamed to Aichi Prefecture in April 1872 and was united with Nukata Prefecture on 27 November of the same year.

The government of Aichi Prefecture is located in the Aichi Prefectural Government Office in Nagoya, which is the old capital of Owari. The Aichi Prefectural Police and its predecessor organisations have been responsible for law enforcement in the prefecture since 1871.

The Expo 2005 World Exposition was held in Seto and Nagakute.

Etymology

[edit]

In the third volume of the Man'yōshū there is a poem by Takechi Kurohito that reads: "The cry of the crane, calling to Sakurada; it sounds like the tide, draining from Ayuchi flats, hearing the crane cry". Ayuchi is the original form of the name Aichi, and the Fujimae tidal flat is all that remains of the earlier Ayuchi-gata. It is now a protected area.[8][9]

For a time, an Aichi Station existed on the Kansai Line (at the time the Kansai Railway) between Nagoya and Hatta stations, but its role was overtaken by Sasashima-raibu Station on the Aonami Line and Komeno Station on the Kintetsu Nagoya Line.
