Ancient Shrines of Japan
Japan's oldest shrines predate written history. Many claim mythological origins, with founding dates recorded in the Kojiki (712 CE) and Nihon Shoki (720 CE). These are the sacred sites where Japan's earliest spiritual traditions were formed.
Japan's Ancient Shrine Hierarchy
The historical importance of Japanese shrines was codified in systems like the engishiki (延喜式, 927 CE), which ranked shrines by their national significance. The highest ranks — Kanpei-taisha and the Nijunisha (22 Shrines) — indicate shrines that received imperial offerings and were considered protectors of the nation.
Note that many founding dates listed are "according to tradition" — their actual origins may predate or postdate these mythological accounts. The Nihon Shoki records founding dates measured from its cosmological calendar, which does not correspond to modern historical chronology.
