Japan’s rape law was rewritten in June 2023. The crime is now called non-consensual sexual intercourse, and prosecutors prove it by showing the victim did not consent rather than by showing the offender used force. The minimum sentence is five years in prison, the age of consent is 16, and charges can be brought up to 15 years after the offense.
Consent Is Now the Test, Not Force
Under the pre-2023 Penal Code, prosecutors had to show that the offender used assault or intimidation severe enough to make resistance “extremely difficult.” Victims who froze, who were too frightened to fight back, or who were incapacitated did not fit the standard, and acquittals were common when there was no evidence of a physical struggle.
The revised law reverses the question. Courts no longer ask whether the offender used enough force; they ask whether the victim consented. The crime was renamed from “forcible sexual intercourse” to “non-consensual sexual intercourse,” and the absence of physical resistance is no longer a reason to doubt that an assault occurred.
The Eight Circumstances That Negate Consent
The Penal Code now lists eight situations in which a person cannot legally consent. If any one of them applies, the act is a crime regardless of whether the victim said no out loud or tried to push the offender away.
- Violence or intimidation by the offender.
- Impairment from alcohol or drugs, whether the victim took them voluntarily or was given them.
- A physical or mental disability that prevents a reasoned decision.
- Surprise or shock that leaves the victim unable to process what is happening.
- Sleep or unconsciousness.
- Abuse of authority or influence, such as by an employer, teacher, or caregiver.
- Fear of social, economic, or professional consequences if the victim refuses.
- Psychological disorientation the offender deliberately induces.
Courts can also look beyond these eight categories when the overall circumstances show the victim could not form or express genuine consent. A supervisor pressuring a subordinate, a partner having sex with someone who is heavily intoxicated, an acquaintance initiating contact with someone asleep — all now fall squarely within the statute.
Age of Consent Raised to 16
Japan raised the age of sexual consent from 13 to 16, the first change since 1907. The previous threshold had been among the lowest in any developed country.
The new law carves out a close-in-age exception so that teenagers in peer relationships are not criminalized. If both people are at least 13 and the age gap between them is less than five years, consensual activity is not a criminal offense. A separate new offense also targets grooming, meaning an adult who deliberately builds a relationship with a child for the purpose of sexual exploitation can be prosecuted even before any sexual act occurs.
Prison Sentences and Civil Damages
Non-consensual sexual intercourse carries a minimum of five years’ imprisonment. There is no fine option. When the assault causes injury or death, the penalty rises to life imprisonment or a fixed term of at least six years, and sentences in serious injury cases regularly exceed ten years.1Japanese Law Translation. Penal Code The enhanced penalty applies whether the injury was intended or resulted from the assault itself.
Victims can also sue separately for civil damages. Japanese courts award consolation money, known as isharyo, to compensate for emotional suffering, with amounts varying based on the severity of the assault and its lasting impact. Because civil claims use a lower burden of proof than criminal prosecutions, a civil case can succeed even when prosecutors decline to file charges or a criminal trial ends in acquittal.
Non-Consensual Photography Is a Separate Crime
A separate national law took effect on July 13, 2023, replacing the patchwork of prefectural ordinances that had previously governed voyeurism. Photographing or filming someone’s sexual body parts or sexual acts without consent, including through clothing, carries up to three years in prison or a fine of up to 3 million yen. Distributing the images to a small group carries the same penalty. Posting them publicly, including through livestreams, raises the maximum to five years or 5 million yen. Keeping the images with intent to share them is punishable by up to two years or 2 million yen even if no distribution has yet occurred.
Simple possession, without any intent to distribute, is not a crime under this law when the victim is an adult. Possession of such images of anyone under 18 is a separate offense under Japan’s child pornography statutes. The law also reaches Japanese nationals who commit these acts outside Japan.
How Long You Have to Report
The 2023 reforms added five years to the statute of limitations for sexual offenses. For non-consensual sexual intercourse, the window is now 15 years from the date of the offense. For cases involving injury, it is 20 years.
When the victim is a minor, the clock does not start running until the victim turns 18. Combined with the 15-year period, this means a child victim of non-consensual intercourse can bring a case until age 33.
Reporting an Assault and Getting Help
In an emergency, call 110 for police. The line operates around the clock and dispatches officers to your location.2U.S. Embassy & Consulates in Japan. Calling for Help
Outside an active emergency, Japan runs one-stop support centers in every prefecture that provide medical care, counseling, and legal guidance in a single visit. Dial #8891 from any phone in Japan to be connected to the nearest center based on your location. The call is free, and centers operate 24 hours a day, every day of the year. Japanese police also staff a dedicated sexual assault hotline at #8103 around the clock.3U.S. Embassy & Consulates in Japan. Victims of Crime
When you file a report, bring identification and any evidence you have, including clothing, messages, and photographs. Give as detailed an account as you can of the date, time, and location. You can ask for a female officer to conduct the interview. Physical evidence degrades quickly, so visiting a one-stop support center or hospital as soon as possible after an assault strengthens both your medical care and any future case.
Foreign residents and visitors who need help in English or other languages can call the Yorisoi Hotline at 0120-279-338, a free consultation service run by the Ministry of Health, Labour and Welfare. The line is open daily from 10:00 a.m. to 10:00 p.m. and handles sexual violence, domestic violence, and other safety concerns.3U.S. Embassy & Consulates in Japan. Victims of Crime
