Two coverings, two effects
編み笠 hides the face in shadow. 彦三頭巾 evokes the dead.
The amigasa is a woven hat worn low enough to conceal the dancer's face. The hikosa-zukin is a black hood with eyeholes. Ugo Town describes its origin as uncertain; the National Theatre's cultural library notes its association with the dead.
What the dance holds together
The tradition is said to combine a dance praying for a good harvest with Bon memorial dancing. The flowing movement of the dancers meets music that is lively and forceful rather than hushed.
When and where
The festival takes place in Nishimonai, Ugo, Akita, every August 16–18. The current municipal guide lists the main dancing on Nishimonai Honcho Street.
