Ameonna

Ameonna (雨(あめ)女(おんな), "rain woman") is a Japanese yōkai thought to call forth rain, illustrated in Toriyama Sekien's Konjaku Hyakki Shūi as a woman standing in the rain and licking her hand. In modern usage in Japan, "ameonna" (or the male equivalent "ameotoko") refers to an unlucky person that seems to be jinxed to have the rain follow them wherever they may go, thus gaining a reputation for ruining special events such as weddings or sporting events.
