Every Japanese school has its seven mysteries: Hanako-san in the third stall of the girls’ toilet, the piano that plays at night, the statue that moves, the anatomical model that walks, and the woman who drags her upper body along the ground at terrible speed. The stories passed between children for decades before a series of books collected them in the 1990s and films followed.

Folklorists began recording them in the same decade, and the records library on this site holds a version of Teke-teke told at a high school in Kobe in 2001, in which she lives in a mirror. These are the youngest yokai in the collection and among the hardest to trace to a first telling.
