Despite its very specific values, meaning its centre around the japanese land and people, Shintoism has made a few interesting attempts to reach the outside world, although unfortunately these weren't too successful. Notable shrines include the Tsubaki Grand Shrine of America, and there are many in Hawaii. As said, it is hard to extent influence outside of Japan, but maybe with a increase of interest outside, there will be some thought into a increase of shrines. Unfortunately it may be a while before this happens, the American shrine however provides some hope.
