Kodama appear in the animated film Princess Mononoke, in which they are portrayed as small, white humanoids with large, rattling heads and mask-like features, similar to bobbleheads. In one scene San (Princess Mononoke) chops down a sapling. They appear to crowd around it. Near the end, when the trees begin to die, kodama can be seen falling from the air and dissolving on the ground.
Kodama are presented as demons in the Megami Tensei series, and sometimes 'evolve' into Sudama.
Kodama is the name of an independent professional wrestler who works for Chikara.
'Kodama' also appears in the video game Okami as a cherry tree spirit which calls upon their god Amaterasu to save the world which was corrupted by the awakening of an evil spirit of Orochi. Kodama becomes a tree again by the end of the scene and bears a 'fruit' which holds the villagers of the regions taken over by Orochi.
