Jorōgumo 絡新婦 (仙台市 賢淵)
is a type of Yōkai, a creature, ghost or goblin of Japanese folklore.
According to some stories, a Jorōgumo is a spider that can change its appearance into that of a seductive woman.
The Edo period legend has it that a beautiful woman would entice a man into a quiet shack and begin to play a Biwa, a type of Japanese lute.
While the victim would be distracted by the sound of the instrument,
she binds her victim in spider silk threads in order to devour the unsuspecting person as her next meal. - wikipedia
