Daisuke is a minor character in the film The Grudge 3, primarily known for his role as the husband of Naoko Kawamata. His background is not extensively detailed, but his actions and dialogue establish him as a caring and protective spouse. When Naoko becomes distressed after discovering a newsletter about Jake Kimble’s death, which was left to shame her, Daisuke reacts with concern. He offers a solution focused on their wellbeing, suggesting that they could move away from Tokyo to a place where no one knows about her past or her connection to the curse.

Daisuke’s core motivation is the safety and happiness of Naoko, seeking to remove them both from a painful situation. His personality is defined by his protective nature. As Naoko begins to explain her plan to travel to Chicago in an attempt to stop the curse that plagues her sister, Daisuke quickly understands what she intends to do. He immediately tries to dissuade her, arguing that the situation is no longer her problem and expressing deep fear for her safety. This moment reveals his practical and cautious side, placing the sanctity of their personal life above the supernatural obligation Naoko feels.

In the story, Daisuke’s role is a small yet significant one. He exists in the world outside the central haunting in Chicago, representing a potential life free from the grudge for Naoko. His pleas for her to stay are heartfelt, but they ultimately fail. Driven by her sense of duty, Naoko ignores his warnings, takes her Itako ritual gear, and journeys to the United States. Tragically, Daisuke’s fears come true as Naoko is killed by a possessed Max Morrison and is subsequently reborn as a new onryo, a vengeful spirit. The film does not reveal whether Daisuke ever learns of his wife’s death or her transformation, leaving his final fate unrevealed. He has no notable supernatural abilities, serving instead as a normal human anchor to Naoko’s past life.
