Cold Fish (2010): Sion Sono's Vicious Deconstruction of Japanese Society
In the expansive, blood-soaked realm of modern Japanese extreme cinema, few directors possess the manic, transgressive energy of Sion Sono. Renowned globally for sprawling, provocative, and deeply surreal epics like Love Exposure (2008) and Suicide Club (2001), Sono reached an entirely new peak of nihilistic brilliance with his 2010 masterpiece, Cold Fish (Tsumetai Nettaigyo). Disguised on its surface as a gritty serial killer thriller, the film operates on a much deeper frequency. It is a pitch-black, deeply disturbing satire concerning the collapse of the traditional Japanese family unit, the paralyzing nature of societal politeness, and the explosive, inevitable consequences of masculine emasculation. It is a film that weaponizes extreme gore not merely to disgust the audience, but to completely shatter the pristine illusion of domestic normalcy.
The film centers on Syamoto (played with agonizing restraint by Mitsuru Fukikoshi), the ultimate cinematic manifestation of a broken, modern patriarch. He is a man so thoroughly beaten down by life—openly despised by his rebellious teenage daughter, entirely ignored by his young, depressed second wife, and failing economically in his claustrophobic business—that he exists in a permanent state of apology. He is the titular "cold fish," drifting aimlessly through a life completely devoid of passion, authority, or emotional warmth.
Enter Yukio Murata, played with terrifying, sociopathic exuberance by veteran Japanese character actor Denden. Murata is everything that Syamoto is not: loud, highly successful, sexually dominant, and relentlessly charismatic. When Murata conveniently intercedes on behalf of Syamoto's shoplifting daughter, he positions himself as a benevolent savior. However, Murata's aggressive friendship is a meticulously crafted predatory trap. Behind the bright neon lights of his massive Amazonian tropical fish emporium, Murata and his hyper-sexualized, equally deranged wife, Aiko (Asuka Kurosawa), operate as ruthless serial killers who execute inconvenient business partners with terrifying casualness.
The True Crime Genesis: The Saitama Dog Lover Murders
What makes Cold Fish particularly chilling is its foundation in grim reality. Sion Sono heavily based the screenplay on the notorious 1993 "Saitama dog lover murders." In reality, the killers were Gen Sekine and Hiroko Kazama, a married couple who operated a lucrative dog-breeding business (which Sono changed to tropical fish for the film). The real-life couple scammed clients out of millions of yen and murdered at least four people who confronted them.
Just like Murata in the film, the real Sekine possessed a terrifyingly efficient method for destroying evidence. He would meticulously dismember the bodies, severing the flesh from the bone. The flesh was chopped into tiny pieces and flushed away, while the bones and personal belongings were incinerated in an oil drum until nothing but fine ash remained, which was then scattered in a nearby forest or river. Sono's depiction of this process in the film is not an exaggeration of horror tropes; it is a grim, historical reenactment of one of Japan's most gruesome modern crimes.
★ Hidden Details
Did you know? Sion Sono shot Cold Fish at a breakneck pace over just 23 days. To coax out Denden's terrifying, BAFTA-nominated performance as the jovial serial killer Murata, Sono utilized a highly unconventional directing method. Instead of discussing character motivation or psychology, Sono simply showed Denden real, uncensored crime scene photographs from actual Japanese murder cases immediately before calling "Action." He left the actor alone to process the horrific imagery, resulting in a performance that perfectly balances mundane, folksy charm with absolute, cold-blooded psychopathy.
"Making the Body Invisible": The Banality of Gore
Once the deeply passive Syamoto is violently forced into Murata's orbit, Cold Fish transitions abruptly from a tense domestic drama into a blood-soaked, surreal nightmare. Sion Sono deliberately chooses not to stylize the violence. There are no slick camera movements or cool, detached aesthetics common to Hollywood slashers. Instead, he presents the butchery with the grim, exhausting, and utterly mundane practicality of a slaughterhouse.
Murata's terrifying catchphrase, "making the body invisible," refers to his industrial process for disposing of his victims inside an abandoned, blood-splattered woodland chapel. What makes these extended, grueling sequences uniquely horrifying is the sheer joy and normalcy Murata and Aiko exhibit during the process. Denden's performance is an absolute masterclass in the banality of evil; he sings pop songs, cracks dirty jokes, eats snacks, and barks folksy orders at the traumatized, vomiting Syamoto while standing up to his elbows in human viscera.
The contrast between Murata's jovial, uncle-like demeanor and the apocalyptic gore he creates forces the viewer into an uncomfortable state of dark comedy. Syamoto is entirely paralyzed by the ingrained Japanese societal instinct to avoid confrontation and maintain the *wa* (harmony), rendering him a captive accessory to mass murder simply because he is literally too polite and terrified to say "no."
Emasculation and the Eruption of the Suppressed
The true emotional and philosophical core of Cold Fish is not the mechanics of the murders themselves, but rather Syamoto's agonizing psychological degradation. Sono poses a disturbing thesis: What does it actually take to wake a dead man up? As Murata systematically strips away every last ounce of Syamoto's dignity—taking over his business, manipulating his daughter, and aggressively seducing his wife—the tension builds toward an inevitable, volcanic eruption.
Syamoto has been emasculated by a modern society that demands subservience and passive consumption. When he finally snaps, shedding his polite exterior, the resulting violence is both deeply cathartic and unspeakably tragic. The staggering, blood-drenched climax of the film suggests a horrifying conclusion: in a society built entirely on repression, politeness, and emotional isolation, the only way a marginalized man can truly assert his own existence is through an act of ultimate, irreversible destruction. Syamoto does not become a hero; he simply becomes a different type of monster.

Is Cold Fish based on a true story?
Yes. The film is closely based on the 1993 "Saitama dog lover murders." A real-life husband and wife, Gen Sekine and Hiroko Kazama, who owned a lucrative dog-breeding business, murdered at least four people. They disposed of the bodies exactly as shown in the film—dismembering them, burning the bones, and scattering the ashes in a river to make the victims "invisible."
Why is the film called Cold Fish?
The title operates on multiple levels. Literally, the main characters are tropical fish vendors. Metaphorically, a "cold fish" is a common idiom describing a person who is emotionally detached, unfeeling, or unresponsive. This perfectly describes both the deeply passive, emasculated protagonist at the start of the film, and the cold, sociopathic nature of the serial killers he becomes entangled with.
What is the meaning of the extreme violence in Sion Sono's film?
In Cold Fish, extreme violence is used as a chaotic catalyst to aggressively strip away the polite, repressed facade of modern society. Sion Sono uses the horrific body disposal scenes not just for cheap shock value, but to illustrate the total breakdown of the traditional family unit and the extreme, destructive lengths required for the emasculated protagonist to finally assert his own existence.
