Kachinas are believed to reside with the tribe for half of each year. They will allow themselves to be seen by a community if its men properly perform a traditional ritual while wearing kachina masks and other regalia. The spirit-being depicted on the mask is thought to be actually present with or within the performer, temporarily transforming him.

Kachinas are also depicted in small, heavily ornamented carved-wood dolls, which are traditionally made by the men of a tribe and presented to girls; boys receive bows and arrows. These wooden dolls are used to teach the identities of the kachinas and the symbolism of their regalia. The identity of the spirit is depicted not by the form of the doll's body, which is usually simple and flat, but primarily by the applied colour and elaborate feather, leather, and, occasionally, fabric ornamentation of its mask.
