This article is about the class of Japanese cities. For the coalition of English cities, see English Core Cities Group.

A core city (中核市, Chūkakushi^?) is a class of Japanese city created by the first clause of Article 252, Section 22 of the Local Autonomy Law of Japan. Core cities are delegated many functions normally carried out by prefectural governments, but not as many as designated cities. To become a candidate for core city status, a city must satisfy the following condition:

• A population greater than 300,000.

Application for designation is made by a city with the approval of both the city and prefectural assemblies.
