Aichi Prefecture is a prefecture of Japan located in the Tokai region of the Chūbu region. The capital is Nagoya. It is the focus of the Chūkyō Metropolitan Area. Originally, the region was divided into the three provinces of Owari, Mikawa and Ho. After the Nou-sama era, Mikawa and Ho were united into a single entity. In 1871, after the abolition of the han system, Owari, with the exception of the Chita Peninsula, was institutionalized 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 November 27 of the same year. The Expo 2005 World Exposition was held in Seto and Nagakute. Located near the center of the Japanese main island of Honshū, Aichi Prefecture faces the Ise and Mikawa Bays to the south and borders Shizuoka to the east, Nagano to the northeast, Gifu to the north, and Mie to the west. It measures 106 km east to west and 94 km south to north and forms a major portion of the Nōbi Plain. With 5,153.81 km² it accounts for approximately 1.36% of the total surface area of Japan. The highest spot is Chausuyama at 1415 m above sea level. The western part of the prefecture is dominated by Nagoya, Japan's fourth largest city, and its suburbs, while the eastern part is relatively less densely populated but still contains several major industrial centers. Due to its robust economy, for the Oct 2005-Oct 2006 period, Aichi was the fastest growing prefecture in terms of population, beating Tokyo, at 7.4%.
