I’ve heard that “persona” means both mask and personality.
Jokers like Hikoichi play an important role in Japanese theater in the recent era.

1. the wizard/wise old man, e.g. Merlin, Gandalf
2. the trickster, joker (this archetype pops up in modern popular literature in the Batman stories, and also as “the Loki mask” in the Jim Carrey movie The Mask, and I would say the Lupin the Third is a modern Japanese version of this archetype)
3. the Knight; Japanese equivalent is of course the samurai; we are here talking about the mythological character, not the historical reality

Oni is considered to be Japanese archetype. Oni first appeared in Kojiki, or The Record of Ancient Matters, completed in 712. Oni are similar to demons, goblins, ogres, devils or trolls known in different cultures. Oni has a human figure, ferocious scarlet (or blue) face with his mouth split to ears, horns and fangs, and mostly have iron rods in his hand. Oni capture people and eat them. Oni, however, is not always labelled as evil but is a rather complex character because it sometimes has a benevolent nature as well as a demonic one; for example, some Oni walk at the head of processions in rituals, sweeping away evil spirits, or Oni Gawara (Goblin roof tiles) are put on the ridge of the roof to ward off evil spirits.

As suggested, Yamanba would be equivalent to Western “witch”. However, Yamanba has two aspects like Oni and there is something of human touch sometimes, so in that sense, it’s not like Witch of the West who is always seen as “bad.”

Personally, I’m much more scared by Hannya than Oni or Yamanba, and have been scared of it since my childhood. Hannya has two sharp horn sprout from the temples, gaping mouth full of gold teeth with upper and lower fangs. So scary!
