In the anime


Depending on the text and translator, the Yamauba appears as a monstrous crone, “her unkempt hair long and golden white ... her kimono filthy and tattered,” with cannibalistic tendencies. In one tale a mother traveling to her village is forced to give birth in a mountain hut assisted by a seemingly kind old woman, only to discover, when it is too late, that the stranger is actually Yamauba, with plans to eat the helpless Kintarō. In another story, she raises the orphan hero Kintarō, who goes on to become the famous warrior Sakata no Kintoki.

Yamauba is said to have a mouth at the top of her head, hidden under her hair. In one story it is related that her only weakness is a certain flower containing her soul.

"Tsukuyomi" is based on the Shinto deity of the same name. though mostly depicted as male, and is seen as the god of the moon. Tsukuyomi was born from the right eye of the primeval being Izanagi during Izanagi's cleansing of himself during his trek into Yomi to see his deceased wife Izanami.
