Who doesn't know the female ghostly figure in tattered kimono with her face hidden behind long and wet black hair? Since the Japanese J-horror boom in the late '90s (and the American remakes), this character has also become a familiar horror icon in the West. But where and when did these at times eerie phantom figures originate? And what do they say about Japan, where traditional and popular culture has long been permeated with macabre tales of wandering spirits from the other side? A documentary in the presence of filmmaker and Asia specialist Yves Montmayeur, along with two restored genre classics, immerses you in the wondrous and sinister shadow world of Japanese ghosts.
