Ms. Eight Feet Tall (八尺様, Hachishaku-sama, also informally called Hasshakusama) is a type of Japanese spirit (Yokai) that takes the form of an impossibly tall female specter often said to have a deep, masculine or feminine voice in which she repeats the interjection "Po" [ぽ] repeatedly, and a habit of preying on children, usually ones who are nine to eleven years old.
