Major Triads
There are multiple, known groups of Kami as recorded throughout history.

Yaoyorozu no Kami
Yaoyorozu no Kami (八百万の神, "Eight Million Gods") refers to the multitudinous gods which exist in all things. Everything in existence as humanity knows it can be attributed to a Kami, as such, Kami which do not fall into one of the Major Triads fall under this category.

Mamorigami
Mamorigami are guardian Kami with whom a Miko has formed a pact with.

Mitamashiro
Mitamashiro are objects which house Kami. They are typically pure, ceremonial objects infused with divine energy by a miko and act as vessel. Mitamashiro are meant to expel Kegare, rather than harm humans.

A weapon which acts as a Mitamashiro, such as a tsurugi or naginata, is called a Mamorigatana.
