Nagisa Ōshima didn't just want to make a movie about sex. He wanted to destroy the very idea of censorship in Japanese cinema. When In the Realm of the Senses—or Ai no Korīda—hit the festival circuit in 1976, it didn't just ruffle feathers; it caused a global legal meltdown. It's a film that exists in a strange, claustrophobic bubble of obsession. You've probably heard the rumors. Yes, the acts are unsimulated. Yes, it’s based on a true story that is somehow even more disturbing than the film itself. But honestly, if you go into this looking for a standard adult film, you're going to be bored, confused, and eventually, probably a little bit traumatized.
It’s a brutal, repetitive, and deeply claustrophobic experience.
The story follows Sada Abe, a former prostitute working as a maid, and Kichizō Ishida, the master of the house. They fall into a hole. Not a literal hole, but an emotional and physical abyss where nothing matters except the next hit of dopamine, the next extreme sensation. They stop eating. They stop talking to the outside world. They basically decide that the only way to prove their love is to push their bodies to the absolute limit of what is survivable.
The Sada Abe Incident: Fact vs. Cinema
To understand why In the Realm of the Senses carries such weight, you have to look at the real Sada Abe. This wasn't some fictional screenplay dreamed up in a writer's room. In 1936, the real Sada Abe was arrested in Tokyo. She was carrying the severed genitalia of her lover, Ishida, in her handbag. She had been wandering the city for days in a state of total euphoria. When the police caught her, she wasn't ashamed. She was smiling.
Japan at the time was a powderkeg of rising militarism. The country was marching toward war. In that context, two people locking themselves in a room to do nothing but pursue pleasure was a radical act of political rebellion. Ōshima leans into this. While the world outside is full of soldiers and nationalistic fervor, Sada and Kichi are in their own private universe.
Critics like Joan Mellen have argued that the film is a profound critique of Japanese society. By choosing "death by pleasure" over "death for the Emperor," the characters are committing the ultimate heresy. It's dark stuff. Really dark.
Why the Film Had to Be Smuggled Out of Japan
The production of In the Realm of the Senses is a legendary piece of film history because it was technically an international crime. Japanese obscenity laws at the time—and even now, to an extent—were incredibly strict regarding the depiction of certain body parts. Ōshima knew he could never process the film in a Japanese lab. If a technician saw the raw footage, the police would have raided the studio immediately.

So, he got creative.
He registered the film as a French co-production. Every day, the exposed film was put into canisters and flown to France. It was edited in Paris, far away from the reach of the Japanese censors. This "loophole" is the only reason the movie exists in its uncut form. When it was finally screened at the 1976 New York Film Festival, the U.S. Customs Service actually seized the print. It took a massive legal battle to get it released.
Breaking Down the "Hardcore" Label
Is it pornography? That's the question that has dogged the movie for fifty years. If you ask a film historian like Roger Ebert—who famously gave it a mixed but respectful review—the answer is "no," because the intent isn't to arouse. It’s to exhaust.
The cinematography by Kenichi Okamoto is gorgeous, using a palette of deep reds and golds. It looks like a classic period piece, which makes the graphic nature of the scenes even more jarring. There’s no "porn" music. There are no cheesy setups. There is just the relentless, almost clinical observation of two people losing their minds.
- The lighting is often harsh and naturalistic.
- The sound design focuses on the wet, rhythmic reality of the acts.
- The pacing is intentionally slow, forcing you to sit in the discomfort.
- There is a total lack of "glamour" in the later stages of the film.
By the time the final act rolls around, the characters look haggard. They look sick. It's a far cry from the sanitized version of sexuality we see in modern Hollywood or the hyper-exaggerated version in the adult industry. It's the reality of addiction.
The Legacy of Nagisa Ōshima’s Vision
Ōshima wasn't a "shlock" director. He was a visionary of the Japanese New Wave. He wanted to prove that cinema could handle any subject matter if handled with artistic integrity. Before In the Realm of the Senses, he had already made waves with Cruel Story of Youth. He was a rebel.

He once said that he wanted to make a film where the actors weren't just "acting" at passion, but living it. This created an incredibly difficult environment for the lead actors, Tatsuya Fuji and Eiko Matsuda. Fuji, in particular, faced a massive backlash in Japan. His career suffered for years because he broke the unspoken taboo of showing everything on screen.
Matsuda’s story is even sadder. She was essentially blacklisted from the Japanese film industry and spent much of her life in France. The film gave them immortality, but it cost them their reputations in their homeland.
Common Misconceptions About the Movie
Most people think the movie is just a series of sex scenes. It's not. There are long stretches of quiet. There are moments of strange humor. There’s also the crushing weight of the historical setting. You see the soldiers marching in the background of some shots, a reminder that the "real world" is just as violent and crazy as what’s happening in that small room.
Another misconception is that it’s "unwatchable." While it's definitely not a "date night" movie, it's incredibly well-made. The framing, the use of the sliding shoji doors to create a sense of voyeurism, and the performances are top-tier. It's art. It just happens to be art that makes people scream.
The film also deals with power dynamics in a way that’s still being debated. Is Sada the victim? Is Kichi? By the end, they have swapped roles so many times that it doesn't matter. They are two halves of a single, self-destructing organism.
How to Approach Watching It Today
If you're going to watch In the Realm of the Senses, don't do it on a whim. It requires a certain mental state. It's currently available through the Criterion Collection, which did a massive 4K restoration that makes the colors pop in a way that’s almost overwhelming.

- Check the historical context first. Read about the 1930s in Japan. It makes the ending hit ten times harder.
- Don't expect a plot-driven narrative. It’s a character study of a descent into madness.
- Watch for the symbolism. The use of the color red isn't accidental—it represents life, blood, and eventually, the end.
Actionable Insights for Film Students and Cinephiles
For those studying film, this movie is a masterclass in "the gaze." Ōshima flips the script on how we look at the human body. He doesn't use the camera to "leery" at the actors; he uses it to document their transformation.
Research the legal precedents. Look up how this film changed the way "obscenity" was defined in the UK and the US. It paved the way for films like Last Tango in Paris (which actually came out slightly before but faced similar hurdles) and Antichrist to be taken seriously as art.
Analyze the score. The music by Minoru Miki is sparse but haunting. Note how silence is used as a weapon during the more intense scenes to heighten the viewer's anxiety.
Compare it to modern "extreme" cinema. Watch it alongside something like The Piano Teacher or Nymphomaniac. You'll see that while modern films have more technology, they rarely capture the raw, desperate humanity that Ōshima caught on 35mm film in the mid-70s.
The film remains a towering achievement because it refuses to blink. It looks directly at the most extreme parts of human nature—the parts we usually keep hidden in the dark—and demands that we acknowledge them. It’s not a movie you "like." It’s a movie you survive.
To truly appreciate the film, look for the 2009 Criterion edition which includes interviews with the actors and a documentary on the real Sada Abe. This provides the necessary guardrails to understand that what you're seeing isn't exploitation, but an attempt to map the limits of the human soul through the medium of the body.
