I also really appreciate the concept of Shintoism, you pray every day at local shrine, thanking the local guardian deity for watching over the land and that's that, it's something really simple and easy and something I could get behind, even if the whole thing is completely unfounded in terms of scientific merit and I am an atheist.
I would willingly convert to Shintoism just because I think it's a wonderful thing that people can have something to believe in and something to put faith into.
