Most of the old provinces of Japan had one or more ichinomiya, which gave rise to place names, such as the city of Ichinomiya, Aichi. Shrines of the lower rank are called ninomiya (二宮, second), sannomiya (三宮, third), shinomiya (四宮, fourth), and so forth.
Ichinomiya developed from the system of classification and ranking of shrines within a province.
