Teru Teru Bōzu is a doll made out of cloth or paper (I used to make it with tissue) to wish for a sunny day. In the Japanese language “teru” means “(sun) shine” and “bōzu” means “boy”. If you wish tomorrow to be a sunny day, you display your teru teru bōzu under the eaves upright. Some people display it upside down to wish for rain.
