When a foreign national who is a victim of domestic violence is staying illegally in Japan, an inspection/examination is conducted at a time and place with full consideration of the victim's physical and mental state and privacy. The examination is stipulated in the "Violation Examination Guidelines" (revised on July 3, 2012). For further protection of domestic violence victims, the "Guideline Measures for Domestic Violence Cases" was enacted on July 10, 2008 under the Act on the Prevention of Spousal Violence and the Protection of Victims.
If the suspect is a victim or a possible victim of domestic violence, the examining immigration officer must conduct the examination at a time and place which gives full consideration to the physical and mental state and the privacy issues of the suspect; when the suspect is a woman, female immigration officers should be assigned to the case as often as possible; in addition, communication must be conducted, where possible, in the victim's mother tongue through an interpreter; and the officer must be careful to ease the feelings of anxiety of the victim by displaying a gentle attitude, seeking to uncover the truth of the case. If the victim or suspect, who is possibly a victim, does not wish to make a statement, the official must not force him/her to do so.
