Shinto is the native religion in Japan with its roots stretching back to 500 B.C., and is a poly-theistic one venerating almost any natural objects ranging from mountains, rivers, water, rocks, trees, to dead notables. In other words, it is based on animism.
Shinto does not have a founder nor does it have sacred scriptures like the sutras or the bible. Propaganda and preaching are not common either, because Shinto is deeply rooted in the Japanese people and traditions. "Shinto gods" are called kami.
