In 1981, a small, unassuming Japanese student in Paris did the unthinkable. He didn't just kill someone. He ate them. Most people know him as the "Japanese Cannibal," but the phrase the man who came to be dinner often circles back to the chilling reality of Issei Sagawa and his victim, Renée Hartevelt. It’s a story that feels like a fever dream or a cheap horror flick, yet it’s 100% real, documented in police files and, later, in the grotesque celebrity status Sagawa enjoyed back in Japan.
Honestly, it’s a mess of a case.
You’ve got a guy who was clearly disturbed, a legal system that dropped the ball, and a public that—for some reason—couldn't stop buying his books. It challenges everything we think we know about justice. How does someone commit a crime that visceral and end up walking the streets of Tokyo as a free man? It wasn't a mistake of identity. It wasn't a "whodunnit." It was a "how is he allowed to do this?"
The Night in Paris That Changed Everything
Issei Sagawa was a 32-year-old PhD student at the Sorbonne. He was obsessed with Western women, specifically tall, blonde ones. Renée Hartevelt was his classmate. She was kind, smart, and apparently, she had no idea she was being hunted by someone she considered a peer. On June 11, 1981, he invited her over to his apartment under the guise of translating German poetry.
He shot her in the neck.
Then, over the course of several days, he performed acts that most of us can’t even fathom without feeling nauseous. He documented it. He took photos. He lived with her remains. Eventually, he tried to dump two suitcases containing her body in the Bois de Boulogne. He was caught because he was clumsy. Bystanders saw him. The police found him. He confessed immediately. Case closed, right? Wrong.
Why the Legal System Failed Renée Hartevelt
This is where the story gets really weird and, frankly, infuriating. French medical experts declared Sagawa "insane." They said he was unfit for trial. Under French law at the time, if you were legally insane at the time of the crime, you couldn't be held criminally responsible. He was sent to a psychiatric hospital.

But his father was wealthy. Akira Sagawa was a high-level executive at Kurita Water Industries. Money talks, even in international criminal law. By 1984, the French were tired of paying for his stay, so they deported him back to Japan.
The French expected Japan to keep him locked up. The Japanese authorities, however, saw it differently. They didn't have the French medical records because the French wouldn't release them, citing privacy or legal technicalities. Japanese doctors looked at him and said, "He’s not insane, he’s just a sociopath." Since he had already been declared "not guilty by reason of insanity" in France, and the French charges were dropped, he couldn't be tried in Japan for the same crime.
He walked out of the hospital on August 12, 1985.
The Bizarre Celebrity of a Cannibal
Imagine walking into a bookstore and seeing a memoir by a guy who ate his friend. That was Japan in the late 80s and 90s. Sagawa didn't hide. He leaned in. He wrote more than 20 books. Some were graphic novels detailing his crime. He became a media personality.
He was a restaurant critic. Seriously.
People were fascinated by the "taboo" nature of his existence. He appeared on talk shows. He acted in adult films. He was even a guest on cooking segments. It’s a dark reflection of how the "true crime" obsession can spiral into something exploitative and ethically bankrupt. The victim, Renée, was almost forgotten in the circus of Sagawa’s public life.

The Man Who Came To Be Dinner: Decoding the Obsession
When people search for the man who came to be dinner, they are often looking for the psychological "why." Why did he do it? Sagawa claimed it was a desire to "absorb" the beauty and vitality of the person he admired. It’s a literalization of a metaphor we use all the time—"I could just eat you up"—pushed to a psychopathic extreme.
It’s important to look at the work of experts like Dr. Robert Hare, the creator of the Psychopathy Checklist. While Sagawa was diagnosed as "insane" in France, his later behavior in Japan suggested a highly calculated, narcissistic personality. He knew how to market himself. He knew how to play the "vulnerable, small man" card to gain sympathy or curiosity.
Some researchers suggest that Sagawa's case highlights a massive gap in international law regarding "medical deportations." When a person is sent back to their home country for psychiatric care, there is often no mechanism to ensure they remain in custody if the home country's diagnosis differs.
Cultural Impact and Media
The case inspired more than just nightmares.
- The Rolling Stones song "Too Much Blood" was partially inspired by the Sagawa case.
- The Stranglers wrote a song called "La Folie" about it.
- Numerous documentaries, including the 2017 film Caniba, have tried to peel back the layers of his psyche.
Caniba is particularly grueling. It’s a sensory experience that doesn't offer easy answers. It just shows a man who is aging, frail, and still seemingly unrepentant about the nature of his desires.
The Loneliness of a Monster
In his later years, the fame faded. The money ran out. Sagawa lived in a small apartment, cared for by his brother, Jun Sagawa. He suffered a stroke. He became a recluse. It’s almost poetic in a way—the man who wanted to "absorb" someone else’s life ended up losing his own health and autonomy long before he actually died in November 2022.

He died of pneumonia at age 73.
There was no big public mourning. Just a quiet end to a very loud and horrific story. But the questions he raised about justice and the "celebrity of the macabre" still haunt the legal systems of both France and Japan.
What This Case Teaches Us About Justice
You can’t just look at this as a "weird story." It’s a warning.
First, it shows that wealth and status can fundamentally break the gears of the justice system. If Sagawa had been a poor immigrant from a different country, would he have been deported back to a life of freedom? Probably not.
Second, it exposes the danger of the "insanity" plea when it isn't backed by rigorous, cross-border cooperation. The disconnect between French and Japanese medical standards allowed a killer to fall through the cracks.
Third, it forces us to look at our own consumption of media. We are the ones who bought the books. We are the ones who watched the interviews. The "monster" exists partly because the public provides a stage for him.
Moving Beyond the Morbid Curiosity
If you’re researching the Sagawa case or similar incidents involving the man who came to be dinner, it's helpful to pivot from the graphic details to the systemic issues they reveal. Here is how you can actually engage with this topic in a meaningful way:
- Study Forensic Psychology: Instead of just reading the "what," look into the "how" of criminal profiling. Understanding the difference between clinical psychosis and psychopathy is key to seeing why the legal system failed here.
- Support Victim Advocacy: Stories like this often center on the perpetrator. Research organizations that support the families of victims of violent crimes, especially in international cases where legal hurdles are massive.
- Audit Your True Crime Consumption: Ask yourself if the media you're consuming is "ethical true crime." Does it honor the victim, or does it turn the killer into a mascot? Cases like Sagawa's only stay relevant because we keep looking at the perpetrator instead of the tragedy.
- Explore International Law Reform: Look into the "transfer of sentenced persons" treaties. Many of these have been updated since the 1980s specifically to prevent situations like the Sagawa deportation from happening again.
The case of Issei Sagawa is a stain on the 20th-century legal record. It’s a story of a woman who deserved better and a man who got away with the unthinkable by being just "interesting" enough to a morbidly curious public. Be careful which stories you feed.
