Naoko Kawamata

Naoko Kawamata is a character in The Grudge 3. Naoko is the younger sister of Kayako Kawamata, the youngest daughter of Mr. Kawamata and Mrs. Kawamata, the sister-in-law of Takeo Saeki, and also the maternal aunt of Toshio Saeki. Naoko spent her childhood with her sister and mother at a small rural village in Japan. The sisters were subjected to their mother's rituals, which traumatized them. Naoko grew up, suffering from nightmares of the rituals and married a man named Daisuke, who later became Kayako's brother-in-law. She was blamed for the deaths (due to her familial connection to Kayako). At some point, she obtained her older sister's diary and a portion of her blood through unknown methods. She was portrayed by Emi Ikehata.
