Shinto
Shinto is an ancient Japanese religion. Starting about 500 BCE (or earlier) it was originally "an amorphous mix of nature worship, fertility cults, divination techniques, hero worship, and shamanism."
Unlike most other religions, Shinto has no real founder, no written scriptures, no body of religious law, and only a very loosely-organized priesthood
Shinto creation stories tell of the history and lives of the "Kami" (deities). Among them was a divine couple, Izanagi-no-mikoto and Izanami-no-mikoto, who gave birth to the Japanese islands. Their children became the deities of the various Japanese clans. Amaterasu Omikami (Sun Goddess) was one of their daughters. She is the ancestress of the Imperial Family and is regarded as the chief deity. Her shrine is at Ise. Her descendants unified the country. Her brother, Susano came down from heaven and roamed throughout the earth. He is famous for killing a great evil serpent.
Their religious texts discuss the "High Plain of Heaven" and the "Dark Land" which is an unclean land of the dead, but give few details of the afterlife.
Ancestors are deeply revered and worshipped
There are "Four Affirmations"in Shinto:
Tradition and the family: The family is seen as the main mechanism by which traditions are preserved. Their main celebrations relate to birth and marriage.
Love of nature: Nature is sacred; to be in contact with nature is to be close to the Gods. Natural objects are worshipped as sacred spirits.
Physical cleanliness: Followers of Shinto take baths, wash their hands, and rinse out their mouth often.
"Matsuri": The worship and honor given to the Kami and ancestral spirits
