I have never seen animism and paganism as mutually exclusive. In fact, I'm guilty of taking it for granted that they're often pretty symbiotic [though of course that is not necessarily always so]. Husband isn't familiar with those terms in English, but based on our discussions, he sees Shinto the same way - both animist and pagan.
Japanese culture can be daunting for me, frankly, when it comes to homogeneity; in part because it is still so highly valued. American wives of Japanese who live in Japan have often reported a kind of claustrophobia because of that, and a lack of privacy that is at least partly related. [My husband refuses to countenance the idea of ever living there again because he has a very individualist bent, and from the time he was a small child detested the cultural restrictions.] Yet there is still an implicit understanding of wide internal variance - hence the emphasis on ritual as a group activity, with the implied understanding that each person's belief is their own. SO much their own that it is not polite to speak of it, except to those with whom you're on very intimate terms.
The way my husband puts it is that it's not so much that the kamisama are not as *important* as the smaller kami, but rather that they are *more* important, and therefore less familiar. It would be rude to always bother the creators, to oversimplify. The land spirits and mechanistic spirits are closer, not higher per se.
My druidry is similar, in that I have no real concept of a creatrix/ creator, and no attachment to one - the Tuatha de Danann and the land spirits and so forth are the ones who are close, so they're the ones I interact with if and when I interact on a spiritual level.
