Shinto
Shinto, also known as kami no michi or the way of the gods, is an ancient polytheistic religion indigenious to Japan. Shinto is central to the Japanese culture and national identity, since previous to the Second World War, the emporer of Japan claimed diety as a kami.
Instead of focusing on a dogmatic system of ethics and doctrine, Shinto's practices consist of diverse rituals and ceremonies. The kami are the powers of nature associted with the sun, storms, trees, mountains, animals, and other facets of nature.
The entry way into a Shinto shrine is always marked by a torii gate, which symbolizes the border between normal life and the divine. The main kami are Amaterasu the sun goddess, who is the legendary ancestor to the Japanese emporer, and Susano the storm god.
