The Moon rabbit or Moon hare is a mythical figure in East Asian and indigenous American folklore, based on interpretations that identify the dark markings on the near side of the Moon as a rabbit or hare. In East Asian mythology, the rabbit is seen as pounding with a mortar and pestle, but the contents of the mortar differ among Chinese, Japanese, Korean, and Vietnamese folklore. In Chinese folklore, the rabbit is often portrayed as a companion of the Moon goddess Chang'e, constantly pounding the elixir of life[1] for her and some show the making of cakes or rice cakes; but in Japanese and Korean versions, the rabbit is pounding the ingredients for mochi or tteok or some other type of rice cakes; in the Vietnamese version, the Moon rabbit often appears with Hằng Nga and Chú Cuội, and like the Chinese version, the Vietnamese Moon rabbit also pounding the elixir of immortality in the mortar. In some Chinese versions, the rabbit pounds medicine for the mortals and some include making of mooncakes. Moon folklore from certain Amerindian cultures of North America also has rabbit themes and characters.
