Teru Teru Bozu

Teru Teru Bozu (てるてる坊主, literally 'shine shine monk') are among Japan's most charming and unmistakably specific folk charms — small white balls of cloth or paper, gathered at the 'neck' with a string, resembling a round-headed ghost figure, hung from window frames and eaves to petition for good weather. Their use is most strongly associated with children and school culture: a child who wants sunshine for a field trip, sports day, or festival will make a Teru Teru Bozu the night before and hang it outside with a sung prayer for clear skies.

The name 'bozu' (monk) connects the charm to an origin story involving a Heian-period Buddhist monk who promised the emperor he could stop incessant rains threatening the harvest. The monk prayed for three days, but the rain continued. The enraged emperor had the monk beheaded, wrapped in white cloth, and hung from a tree — whereupon the skies immediately cleared. The hung white-clad bundle became a template for weather petitions, though the modern child's version has lost all of the grisly original details in favor of the charming ghost-doll form.

A subtler tradition involves the direction in which the Teru Teru Bozu is hung: if hung right-side up, it is asking for sun; if hung upside down (called 'Furi Furi Bozu'), it is asking for rain — a modification particularly used by farmers wanting irrigation rain and by children who want a snow day canceling school. This bidirectional function makes the charm one of the few traditional luck objects in Japan that can petition for weather in either direction depending on the petitioner's needs.
