Tsurara Onna

In Japanese folklore tsurara onna are a yokai also known as icicle women. Sometimes during winter, lonely single men will gaze at icicles and admire them. Their beauty inspires them to wish for a wife just as beautiful. Soon after, tsurara onna will appear, presenting as an ordinary woman who the man proceeds to fall hopelessly in love with.

Although the women are extremely beautiful, they disappear as the ice melts, leaving the men even more lonley and sad than before. Tsurara onna is sometimes confused with another yokai called yuki onna.
