The Shinto kami are the spirits or phenomena that are worshipped in the religion of Shinto. They are elements in nature, animals, creationary forces in the universe, as well as spirits of the revered deceased. Many Kami are considered the ancient ancestors of entire clans, and some ancestors became Kami upon their death if they were able to embody the values and virtues of Kami in life. Traditionally, great or charismatic leaders like the Emperor could be kami. The deities of Japan are not all Shinto; many are Buddhist.
