History
Originally, the region was divided into two provinces of Owari and Mikawa.: 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 November 27 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.
