The only story I could find after googling "North Korea giant rabbits" was this:
BERLIN: A German farmer who sold 12 giant rabbits to North Korea with the aim of setting up a breeding program to alleviate famine has said he was shocked to hear they were eaten at Kim Jong-il's birthday banquet.
Which I mean… they were sent as gifts to be breeding stock for meat production. It seems more like a mismanagement of charity resources than a sad story to me.
Yep. Stuff like The Ring girl, the slit mouth girl, along with the ancient ones like Yukki Ona, all sorts of Yokai exist. It basically encompasses all ghosts and fairy tales, though many are taken very superstitiously and seriously.
