Amatsumara

Amatsumara is mentioned in the Kojiki tradition as a kami who serves as a smith for the gods in Takamagahara. In accounts of the Amaterasu cave episode he is said, in many versions, to have made a mirror with the help of Ishikori-dome no Mikoto; that mirror was used to lure Amaterasu from her hiding place in the rock cave of heaven.

The available sources do not provide an extended physical description. The name Amatsumara is glossed in sources as ma-ura and is interpreted by some commentators to mean 'one‑eyed,' an interpretation linked in the sources to the occupational hazards of blacksmithing, but no direct iconography or canonical bodily description is given in the provided excerpts.

Sources describe Amatsumara as the divine practitioner of ironworking and blacksmithing, acting as a smith for the gods in Takamagahara and serving as a patron kami for human blacksmiths. He is credited in many versions of the Amaterasu cave episode with making a sacred mirror (in collaboration with Ishikori-dome no Mikoto). The provided material does not ascribe hostile, underworld, possession, or broadly supernatural powers beyond his role as a divine artisan and patron of the craft.
