Hmmm, as far as I'm aware, not really. There is a Shinto shrine in Taiwan, and there are a few scattered around the world - but Shinto as a whole is pretty rare. I've never met a Japanese person who said "I'm Shinto", all of my Japanese friends will say "I'm Buddhist" or "I have no religion".
But, they all go to the Shrine on New Years', they say their itadakimasu and gochisosama ("grace" if you will) before and after eating, and quite a few of them of them even have a kamidana (God-shelf, a kind of altar) in their homes, and during discussions with them, 5/5 say (that is, I've spoken to 5 about it, and all 5 have said) about how everything has a kami.
But no, they don't classify it as religion, it's just so deeply ingrained into their culture that they don't see it as religion or superstition, but part of the way of life.
There are some people who are Shinto 'converts', but it's not really considered that important by most Shinto followers. Ironically enough, my friend Noah is a Shinto convert.
- Unfortunately, many of his Japanese friends feel he is being dishonest religiously and don't understand
why he would do that.
