In Himeji, if you chant the phrase three times in the privy on New Year’s Eve, a severed head falls; wrap it, take it home, and when held to a lamp it turns to gold. In Kōshi Yawa, calling its name at the dead of night makes a nyūdō head appear; tuck it into your sleeve and it becomes koban coins. By contrast, Zōgen says merely recalling the phrase is ill-omened. In Wakayama it is called “Setchin-bō” and is said to emit birdlike cries, and in parts of Okayama it’s conflated with the Mikoshi Nyūdō, summoned by a spoken formula.
