The Comparison of regions of Japan highlights differences and similarities. The regions of Japan are a fusion of historical divisions and modern administrative needs".

Geography and culture
The geography and administrative subdivisions of Japan have evolved and changed during the course of its history. Since the late-7th century, the regions of Japan have been grouped according to geographic position.

In the Meiji period, the modern regional system was made by Imperial decree. Japan was divided into regions (chihō ). A regional council (chihō gyōsei kyōgisai) was headed by the governor of the most powerful prefecture in the regional grouping. The council also included regional chiefs of central government ministries.
In this time, political development is marked by persistent loyalty to region and locality.
