Continuity mistake: When Chizuko is first introduced, she is having her makeup and hair done by a group of stylists. A man with a makeup brush is shown brushing the left-hand side of her face. When the camera cuts to a closer shot of Chizuko, the makeup brush is now on the right-hand side of her face. (00:08:30)
Continuity mistake: Whilst the family are on their way to the parents' house, Inoue takes out a sandwich in his mouth to show to a driver in the car beside him. After he takes the sandwich out of his mouth, the sandwich and the hand he is holding it in, rotate 90° in between shots. (00:17:13)
Continuity mistake: When Inoue starts kissing Yoshiko, there is a moment where she puts her left hand on the left side of his hair. When the camera changes angles, her left hand is now on his upper back. (01:03:18)
Visible crew/equipment: Whilst Inoue is talking with Yoshiko in secret, just after he says "No, the day after tomorrow I'll call you for sure", she lifts up her head slightly to make eye contact with him. When she does this, the film crew can be seen reflected in her glasses. (01:03:45)
Audio problem: Inoue drags a hysterically-laughing Yoshiko back to Aoki's car after they have sex, and he gets his pants wet. Once she is in the car, she is still heard laughing hysterically, but her mouth isn't open far enough for laughs that loud to be coming out. The laughs were likely dubbed in. (01:11:58)
Continuity mistake: When Yoshiko and Aoki are leaving the funeral, in the shot of them driving past Inoue, Yoshiko is sitting down in the passenger seat, facing forwards. In the next shot, she suddenly has her right arm placed against the back, and is facing 90° to the right so that she can wave goodbye to Inoue. (01:12:06)
