Yuki Onna (雪女, snow woman) is a spirit or yōkai in Japanese folklore. She is a popular figure in Japanese literature, manga, and animation.
Yuki-onna appears on snowy nights as a tall, beautiful woman with long black hair and blue lips. Her inhumanly pale or even transparent skin makes her blend into the snowy landscape (as famously described in Lafcadio Hearn’s Kwaidan: Stories and Studies of Strange Things). She sometimes wears a white kimono, but other legends describe her as nude, with only her face and hair standing out against the snow. Despite her inhuman beauty, her eyes can strike terror into mortals. She floats across the snow, leaving no footprints (in fact, some tales say she has no feet, a feature of many Japanese ghosts), and she can transform into a cloud of mist or snow if threatened.
Some legends say the Yuki-onna, being associated with winter and snowstorms, is the spirit of someone who perished in the snow. She is at the same time beautiful and serene, yet ruthless in killing unsuspecting mortals. Until the 18th century, she was almost uniformly portrayed as evil. Today, however, stories often color her as more human, emphasizing her ghost-like nature and ephemeral beauty.
