History

Originally, the region was divided into two provinces of Owari and Mikawa. 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

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.

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.
