While it is often claimed that the subsequent feature-length video films "" and "Ju-on: The Curse 2" are remakes of "Katasumi" and "4444444444", the two segments "are actually the foundations of "Ju-on"", according to Shimizu, and act "almost like the true prequel of the story." "Katasumi", in particular, is notable for marking the first appearance of actress Takako Fuji (at this point anonymous) as Kayako Saeki, a role that she would reprise for every "Ju-on" production thereafter, up to "The Grudge 2".
