"Ringu" is the original Japanese film that inspired "The Ring," an American remake. Both movies have their own unique approaches to storytelling and horror, and some viewers may find one scarier than the other. It ultimately depends on individual preferences and what elements of horror resonate with each viewer.

In 1998, Hideo Nakata made a new Japanese adaptation of the book in his film Ring (also known as The Ring or Ringu). The film was a critical and commercial success, being credited with revolutionizing the J-horror genre and influencing many future films in the wider horror genre.
