TeruTeruBozu - japanesse rain doll

Teru teru bōzu (Japanese: てるてる坊主; "shiny-shiny Buddhist priest") 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).

Teru teru bōzu became popular during the Edo period among urban dwellers, whose children would make them the day before the good weather was desired and chant "Fine-weather priest, please let the weather be good tomorrow."

Today, children make teru-teru-bōzu out of tissue paper or cotton and string and hang them from a window to wish for sunny weather, often before a school picnic day. Hanging it upside down - with its head pointing downside - acts like a prayer for rain. They are still a very common sight in Japan.
