There is a very large and highly prestigious Inari shrine in Okayama Prefecture called “Saijo Inari,” but the person reporting says they used to go there often and remember it well, and yet...
Furthermore, Fushimi Inari is an independent line and is an Inari-faith type of Inari shrine like Yutoku Inari and Kasama Inari, but Toyokawa Inari and Mogami Inari have become temples, which was surprising, he says. As for Toyokawa Inari, now of the Soto sect (a Buddhist school), he remembers it as not belonging to a sect, and as for Mogami Inari, now of the Tendai sect, it should originally have been in the Shingon lineage and become independent after the war. He also remembers that Toyokawa Inari, before becoming independent, was of the Shingon sect. Incidentally, with respect to Fushimi Inari, it seems there remained an anecdote that it has ties with the Shingon sect. Also, many local Inari shrines have changed to being under Fushimi Inari. Previously the lineages were a jumble, and in Kyushu there were mostly Yutoku Inari lineages; in Chugoku and Shikoku it was either Fushimi Inari or Mogami Inari lineages (due to the influence of Kobo Daishi Kukai, there were many Mogami Inari lineages as well); in Kinki it was Fushimi Inari lineages, but in Chubu/Nagoya it was Toyokawa Inari lineages, and in the Kanto region there should have been many Kasama Inari lineages; but now, he says, it has changed to an overwhelmingly single-strong Fushimi Inari lineage.
