Incidentally, Yorozuhatatoyoakitsushi Hime (along with Amaterasu) was one of the three gods of the Naiku (the Inner Shrine) in Ise-jingu Shrine, which names her as a high-ranking god that cannot have been a mere wife of another god's son.
ちなみにヨロヅハタトヨアキツシヒメは伊勢神宮の内宮の三神の一人であり（もう一人はアマテラス）、単なる息子の妃では考えられない程の高位の神である。
