A Teru teru bōzu is a little traditional hand-made doll made of white paper or cloth that Japanese farmers began hanging outside of their window by a string. This amulet is supposed to have magical powers to bring good weather and to stop or prevent a rainy day. “Teru” is a Japanese verb which describes sunshine, and a “bōzu” is a Buddhist monk (compare the word bonze), or in modern slang, “bald-headed”; it is also a term of endearment for addressing little boys.

And if you are in need of rain, you can simply hang your teru teru bozu upside down and he will invite the rain to come. This little spirit is a friend of all children which want to spend they free time out-of-doors!!
You can also use him for Halloween decoration I definitely love it!
