Byōbunozoki (folding screen peeper) is a Japanese monster in the collection of monster paintings by Toriyama Sekien, "Konjaku Hyakki Shūi".[1]
According to the commentary in The One Hundred Demons, the Byōbunozoki is a monster who looks at a person from the outside of a folding screen, and looks beyond the 7-inch folding screen. According to Chinese classics, the Qin Shio emperor jumped over the screen of Xianyang Palace when he was about to be murdered.[2] [3] [4]
