In honor of the 10th anniversary of the Ju-on series, the fifth and sixth installments titled Ju-on: White Ghost and Ju-on: Black Ghost premiered in simultaneous screenings in theaters in Japan on June 27, 2009.[6] Takashi Shimizu and Taka Ichise returned to supervise the films' production, each with a different director.
White Ghost revolves around a son that brutally murdered all five of his family members and ultimately hanged himself. One of the victims was his niece Mirai, who he had sexually abused. Mirai's childhood friend Akane saw evidence that she was being sexually abused by her uncle, but was unable to help her. Several years later Mirai's spirit came to haunt her.
Black Ghost revolves around a girl named Fukie who has been having bizarre attacks accompanied by a death rattle. Test results show a cyst inside Fukie’s body, but that cyst is actually the physical remnant of a twin that Fukie's body partially absorbed in the womb. The cyst holds a grudge for not being born and influences several characters to commit murder sprees via spiritual possession. Fukie's mother, Kiwako takes the spirit (inside Fukie's body) and jumps off the hospital rooftop with it, killing them both. However, this leads to the spirit being released from the body.
