The idea that the god of the sun (Amaterasu Omikami) and the god of the moon (Tsukuyomi) were born from the eyes of Izanagi shows a strong influence of Taoism, whose canons "Reiho gobujo" (completed by the sixth century) and "Goho innenkyo" (written at the beginning of the seventh century) respectively contain descriptions of "turning his eyes into the sun and the moon" and "turning his left eye into the sun and his right eye into the moon."
天照大神・ツクヨミの太陽・月の神の「目」からの誕生は道教の経典・教理書の『霊宝五符序』（6世紀以前）に「目を日月となす」、『業報因縁経』（7世紀初頭）に「左の眼を日と為し、右の眼を月と為し」とあり、道教の強い影響が指摘されている。
