Jorougumo is a type of spider demon that can change it's appearance to that of a seductive woman. It can be written in Japanese as either "Binding Bride" or "Whore Spider". In Edo legend a beautiful woman would seduce a man into a shack and begin to play a Japanese lute called Biwa. While her victim is distracted by the instruments melodies, she binds them in spider silk threads in order to devour the unsuspecting man as her next meal. Legends say that a spider must be 400 years old before it gains magical powers, which she then uses to change her appearance into a beautiful woman to ask a samurai to marry her or takes the form of a young woman carrying a baby which might be the spiders eggsack.
