ushi no koku mairi
Ushi no koku mairi (Japanese: 丑の刻参り, lit. "ox-hour shrine-visit") refers to a prescribed method of laying a curse upon a target that is traditional to Japan, so-called because it is conducted during the hours of the Ox (between 1 and 3 AM).
The person performing the curse is generally portrayed as a woman dressed in white, with disheveled hair, wearing an iron "crown" that holds three burning candles, suspending a mirror from her neck and wearing a pair of geta. She would then nail a straw doll representing her target to a sacred tree at a Shinto shrine.
