A kodama (木霊 or 木魂) is a spirit in Japanese folklore that lives in a tree (similar to the dryads of Greek mythology). Also known as kodama is the tree itself where one of these spirits dwells. On the other hand, the echo phenomenon, within Japanese folklore, is also known by this name.
Kodamas are spirits from the mythology of Japan, inhabitants of thick forests. They are usually human in appearance, and each individual is unique in appearance and personality.
It is said that they can appear in non-human forms, and can appear as beautiful or terrible as they wish. Most of them are shown with an adorable appearance. Their bodies, short in stature, are semi-transparent, pale green or off-white.
In Japanese mythology they are known as tree spirits in general. They do not necessarily represent a particular tree, although some of them are directly associated with a specific tree. It is believed that these spirits can move to another tree, or be born through its seed.
Most of these spirits are displeased with those who have no respect for the environment. If a tree is cut down irresponsibly, one or more kodamas may seek revenge. Most of these spirits are peaceful and calm in nature; they like to share knowledge and wisdom with those who know how to communicate with them.
Kodamas are surprisingly strong and powerful spirits, given their long lifespan. Their communication with the world and forces goes beyond the understanding of many other beings.
