Amaterumitama-no-Kami is a Shinto kami whose name is associated with radiant or illuminating spirit, linking it to solar and light-related reverence found in various local shrine traditions across Japan. This deity is often enshrined at smaller regional shrines, where devotion to it is tied to general protective and guardian roles attributed to kami of light. As with many kami of this type, specific attributes and honors vary by locality and shrine record, and documentation of a single unified mythology is limited.
