One of the ujiko wondered why shi-yaku-jin no hokora is called hokora and not jinja (or any of the other terms usually asociated with a shintô shrine).

There are several reasons for this, not the least of which is it's are not tended by a shinshoku either full or part-time — jinja usually have one or more attendant shinshoku, at least part-time.

I do not and have never claimed to be shinshoku. I do use the term kannushi in its older sense of someone who keeps and tends a shrine (which I do), but not in its more recent conflation with shinshoku.

If you lookup the definition of hokora, it will say something along the lines of, "A small shintô shrine dedicated to folk kami, either found on the grounds of a larger shrine, or on the side of a street, or in the countryside. They usually enshrine local kami not under the jurisdiction of any of the larger shrines or networks."

That pretty much fits shi-yaku-jin no hokora — it's small, it's family owned, it doesn't belong to any of the shrine networks or associations, and it's dedicated to attending to the local kami of misfortune.

So hokora is a much better fit.
