the country of the legend : japan

The Yuki Onna  or the snow women , is a yûrei , which mean a  Japanese ghost, and therefore belongs to the youkai a name attributed to the supernatural beings like the spirits, demons and other monsters of the folklore of the archipelago.

Although it has several names, depending on the regions where it appears or the legends which are told about it, the name of Yuki Onna is a generic and easily identifiable name which includes a certain number of "sub-categories", but that doesn't change the nature of that spirit or what it represents. 

The Yuki Onna would  sometimes be cited as being more than 3 meters tall, of very great beauty and serene appearance but whose evil look would be able to kill.

 Depending on the legend , her hair can be black or white, probably by assimilation with snow or in order to blend more easily into the landscape. Her lips are blue, reminiscent of ice or the color of a person who died of cold, and her skin is so pale that it is often described as transparent, only certain features of hes face and her hair then stand out in the middle of the landscape. ; and of course, her skin is very cold to the touch. She is sometimes described wearing a white kimono

she moves without leaving a trace and therefore floats, but it probably does not have feet like all Japanese ghosts (which is not the case with other categories of supernatural beings in Japan).If she feels threatened, she  can turn into thick fog or snow.

The most famous legend of Yuki Onna was written by Lafcadio Hearn (or Yakumo Koizumi 1850-1904), essential writer in the knowledge of Japanese folklore, in his collection "Kwaidan: Stories and Studies of Strange Things" (1904). It was reportedly brought to him by a farmer from the Musashi province.

the legend say that while a terrible storm was raging over the forest, the lumberjack Mosaku and his 18-year-old apprentice Minokichi took refuge in a small cabin in the middle of the forest. During the night, the fire in the fireplace went out and the cold woke Minokichi.

It was then that he saw in the small room a young women of great beauty and dressed in a white kimono; she had unreal whiteness, long black hair and blue lips. When she walked she seemed to glide above the ground.

She leaned over the old woodcutter and blew his icy breath in his face taking his life from 

Then she turned to the young man who was paralyzed by fear, but she was taken pity at his young age or his youthful beauty and said to him: "I will not kill you if you promise never to tell what you have seen tonight. "

The next morning Minokichi woke up and realized the death of his boss but he could not say whether, during this terrible night he had dreamed or not .

He came back to his village without his companion still shaken up from the events of the night before, while walking he meet a lovely woman and instantly fall for her .

The two starts then meeting up with each other going out together and sharing every day in the company of the other, minokichi ends up then proposing to her .

Many years later, Minokichi, married to his splendid wife and happily became father of three children, yet he still cannot forget that eventful night in the snowy forest , his wife seeing the shaken up expression that her husband was making concerned she asks him about it , he ends up confiding to her breaking with it his promise to the yuki-onna .

Furious, his wife admits to him that she is the yuki-onna , transforming to her true self while walking to the unfortunate man with the intension of ending his life , yet she stops and turn to take a look at their sleeping children , after a few seconds of staring she decided yet again to not kill him because of the children since she wants them to have a parent figure to take care of them .

this time, she promises to return if he is not a good father to them , and if he fails he won't get another chance. So she  melts and disappears forever.

and we never heard about her again .
