Kososhin (Imperial Ancestor) (皇祖神)

Kososhin is the god deemed to be the ancestor of Imperial Family. Nowadays the term refers to Amaterasu Omikami (the Sun Goddess).

Historian Masao OKA, scholar of ancient literature and mythology Ken MATSUMAE, and so on have the theory that the original kososhin was Takamimusubi, and Amaterasu Omikami was later set up as kososhin.
