[2]: 11, 126  Aichi Prefecture has a population of 7,552,873 (as of 1 October 2019[update]) and a geographic area of 5,172.92 square kilometres (1,997.28 sq mi) with a population density of 1,460 inhabitants per square kilometre (3,800/sq mi).

Aichi Prefecture had many locations with the Higashiyama Zoo and Botanical Gardens, The Chubu Centrair International Airport, and the Legoland Japan Resort.

These are the towns and villages in each district: As of 2001, Aichi Prefecture's population was 50.03% male and 49.97% female.

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.

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.

Companies such as Fuji Heavy Industries, Mitsubishi Motors, Pfizer, Sony, Suzuki, Bodycote, and Volkswagen Group also operate plants or branch offices in Aichi.

Notable sites in Aichi include the Meiji Mura open-air architectural museum in Inuyama, which preserves historic buildings from Japan's Meiji and Taishō periods, including the reconstructed lobby of Frank Lloyd Wright's old Imperial Hotel (which originally stood in Tokyo from 1923 to 1967).
