Why this shrine is called an ichinomiya
The shrine names a historical document
No public body was found describing it this way, but the shrine names a historical document that calls it the ichinomiya. We have not read that document ourselves.
Listed on the map published by the Ichinomiya Pilgrimage Association.
The shrine’s own website gives two grounds: that in the shrine register of the Engishiki (Izumo manuscript) it is “recorded as the only myōjin taisha among the thirty-four shrines of Ecchu Province”, and that the Hakusan no ki, an Important Cultural Property designated by the national government, records it as “the ichinomiya of Ecchu”.
