Ichinomiya

Ichinomiya (一宮; also 一の宮 or 一之宮; first shrine) is a Japanese historical term referring to the Shinto shrines with the highest rank in a province. Shrines of lower rank were designated ninomiya (二宮; second), sannomiya (三宮; third), shinomiya (四宮; fourth), and so forth.

The term gave rise to modern place names, such as the city of Ichinomiya, Aichi, named after Masumida Shrine in the former Owari Province.
