Су тамшысы және ұлының құрбаны

is a 2002 Japanese supernatural horror drama film directed by Hideo Nakata and written by Yoshihiro Nakamura and Kenichi Suzuki, based on the short story collection by Koji Suzuki. The film stars Hitomi Kuroki, Rio Kanno, Mirei Oguchi, Asami Mizukawa, Fumiyo Kohinata, Yu Tokui, Isao Yatsu and Shigemitsu Ogi. The plot follows a divorced mother who moves into a rundown apartment with her daughter, and experiences supernatural occurrences including a mysterious water leak from the floor above. An American produced remake of the film, directed by Walter Salles and starring Jennifer Connelly and Tim Roth, was released in 2005.

Amidst a divorce, Yoshimi Matsubara struggles to rebuild her life. She rents a run down apartment, enrolls her daughter Ikuko in a nearby kindergarten, and gets a job as a proofreader in a small publishing company. The ceiling of their apartment has a leak that continually worsens. Matsubara complains to the building superintendent to no avail. Yoshimi begins experiencing strange occurrences around the complex. A red bag reappears no matter how often she tries to dispose of it; she gets glimpses of a mysterious long haired little girl. Several incidents remind her of the time she was abandoned as a child. She is regularly late to pick up Ikuko from school and is stressed when her ex husband tries to take Ikuko. Yoshimi learns of Mitsuko Kawai, who went missing a year earlier, from a missing person photo of her with a yellow raincoat and red bag. The little girl used to live in the abandoned unit right above Yoshimi's. One day, Yoshimi finds Ikuko in the apartment upstairs, where the faucets have been left running and have flooded the entire unit. Her lawyer talks to the superintendent, who finally agrees to fix the issue. Afterwards, things seemingly return to normal but the red bag reappears. Yoshimi heads to the building roof and notices that the water tank was last opened and inspected over a year ago, shortly before Mitsuko was last seen. She has a vision and realizes that Mitsuko fell into the tank while trying to retrieve her red bag and drowned. Meanwhile, Mitsuko's ghost attempts to drown Ikuko in the bathtub. Yoshimi rushes back to her apartment, grabs Ikuko, and flees from Mitsuko. However, as the elevator door closes, she sees that the figure pursuing her is her daughter – she is carrying Mitsuko. Mitsuko clings to Yoshimi, who realizes she won't go. With Ikuko watching tearfully, Yoshimi sacrifices herself to appease Mitsuko's spirit, who claims Yoshimi as her mother in a heavy torrent of water. 10 years later, Ikuko, now a high schooler, revisits the now abandoned block and notices that her old apartment looks oddly clean and lived in. She sees Yoshimi, who looks the same. Yoshimi apologizes that they cannot be together, and affirms that she is happy as long as Ikuko is alright. Mitsuko appears by her side and they disappear together.

The film was released theatrically in Japan on January 19, 2002, where it was distributed by Toho and received a total domestic gross of $906,344. The film grossed a total over $1.4 million worldwide.

On the review aggregator website Rotten Tomatoes, Dark Water has an approval rating of 84% (based on 19 critics). Peter Bradshaw of The Guardian gave the film 4 out of 5 stars, writing that "The movie's denouement delivers not just a flash of fear but a strange, sweet charge of pathos and the combination adds up to the most disturbing spell in the cinema I've had in a very long time". Alexander Walker of the London Evening Standard also gave the film a positive review, writing that "Its cleverness relies on transferring our concern from the supernatural events emanating from one lost child to the natural fear of a mother losing her own child to the other world." Katie Rife of The A. V. Club recommended the film for horror fans, writing that "The J horror boom of the '90s and early '00s produced some extremely creepy ghost stories, and Dark Water is one of the creepiest, and saddest, of them all." Thomas Spurlin of DVD Talk gave the film 3.5 out of 5 stars, writing that it "doesn't pack as much of a suspenseful punch as other entries in the J Horror subgenre, but the heaviness of its supernatural moisture soaked atmosphere and the melancholy angle of its parental theatrics fill that void". Nicholas Rucka of Midnight Eye called the film "a simply passable horror viewing experience", criticizing its "weak story resolve and mediocre characterization" but writing that it "is worth watching for a good chill." In 2020, Katherine McLaughlin included the film in a list of 10 great Japanese ghost stories, referring to the film as an "eerie and heartbreaking adaptation" that "strikes a disquieting mood".
