Twenty years ago, people packed theaters to watch a couple of Japanese teenagers view a strange videotape and soon after receive an ominous phone call with a cryptic message: ¡°Seven days.¡±

Hideo Nakata¡¯s 1998 film ¡°Ringu¡± (known as ¡°The Ring¡± overseas) was just one of a number of films ¡ª Kiyoshi Kurosawa¡¯s ¡°Cure¡± (1997), Takashi Miike¡¯s ¡°Audition¡± (1999), Takashi Shimizu¡¯s ¡°Ju-on: The Grudge¡± (2002) ¡ª that brought terror to cinemas around the world under the label of ¡°J-horror¡± around the turn of the century.

Unlike the horror flicks of Hollywood, with their voracious zombies and inhuman serial killers, J-horror was typically populated by vengeful female ghosts who would attack their victims with single-minded implacability. The roots of such characters lay in kaidan, ghost stories from Japan¡¯s past.
