Seiryu Gongen (Blue Dragon Avatar) is a deity venerated in Japanese Shinto-Buddhist syncretism, associated with dragons as embodiments of water, rain, and the forces of nature. Enshrined at sites such as Daigo-ji temple in Kyoto, this figure is regarded as a protective guardian spirit tied to mountain and water landscapes. As a gongen, the deity reflects the honji suijaku tradition in which a Buddhist entity manifests in a native, dragon-like form to guard a sacred place.
