Characteristics

The most immediately striking theme in the Shinto religion is a great love and reverence for nature. Thus, a waterfall, the moon, or just an oddly shaped rock might come to be regarded as a kami; so might charismatic persons or more abstract entities like growth and fertility.

As time went by, the original nature-worshipping roots of the religion, while never lost entirely, became attenuated and the kami took on more reified and anthropomorphic forms, with a formidable corpus of myth attached to them.

The kami, though, are not transcendent deities in the usual Western and Indian sense of the word - although divine, they are close to us; they inhabit the same world as we do, make the same mistakes as we do, and feel and think the same way as we do. Those who died would automatically be added to the rank of kami regardless of their human doings. (Though it is thought that one can become a ghost under certain circumstances involving unsettled disputes in life.)

Belief is not a central aspect in Shinto, and proper observation of ritual is more important than whether one "truly believes" in the ritual. Thus, even those believing other religions may be venerated as kami after death, if there are Shinto believers who wish them to be.
