And just an FYI this film is part of a series called "J-Horror Theater". This was meant as a series of 6 movies. So far 5 have been release, 3 of which are on DVD (those 3 being Premonition, Infection, and Reincarnation) Here are the 5 in this series that are released so far:
These 3 are on DVD
Infection (aka Kansen) by Masayuki Ochiai released: 02 October 2004.
Premonition (aka Yogen) by Tsuruta Norio released: 02 October 2004.
Reincarnation (aka Rinne) by Takashi Shimizu released: 07 January 2006.
These 2 have yet to be released on DVD
Retribution (aka Sakebi) by Kiyoshi Kurosawa released: 24 February 2007.
Kaidan by Hideo Nakata Released: 4 August 2007
The last two were meant to be in the series, but arent listed as "J-Horror Theater" so the common thought is they abandonded this series title and are just releasing them normally.
The final film in the series is rumored to be an unknown film by by Hiroshi Takahashi
