Content note: this piece describes the murder of a woman in her own home while her two-year-old son was in the room, and the twenty-six-year investigation that eventually named her killer. It is a companion piece to the Miyazawa/Setagaya article; where that one ended in silence, this one ends in a door opening at a Nagoya police station on Halloween 2025.
Cold Does Not Mean Dead
Look. If you have just read the Miyazawa piece, or if you have ever loved someone through a case that never closed, I need you to sit with this next fact for a second before we start, because it is the whole reason I am writing this piece next.
Cold does not mean dead.
On the afternoon of October 31, 2025 — Halloween in most of the world, a completely ordinary autumn Friday in Japan — a sixty-nine-year-old woman named Kumiko Yasufuku walked into a Nagoya police station and told the officer at the desk that she was there to turn herself in for a murder she had committed twenty-six years earlier. She had killed a woman she had never met, in that woman’s own apartment, in front of that woman’s two-year-old son, on a Saturday afternoon in November of 1999, because that woman was married to a man Yasufuku had loved since she was seventeen and had never been able to have.
For twenty-six years the case had sat cold. Five thousand people had been interviewed. Blood, DNA, footprints, and a five-hundred-metre trail of blood spatter leading away from the apartment had been on file since the day of the murder, and none of it had matched any name in any Japanese database. The killer had lived a completely ordinary life ten kilometres from the crime scene the entire time. Married. A part-time job. Two decades in the same neighborhood. She had walked past the widower’s life for years and he had, at various points, wondered if she was the one. He had told the police her name, quietly, more than once. They had watched her. They had never had enough. Until 2025.
I need you to hold that in your chest, because it is the note the Miyazawa piece could not end on. In that piece, the killer is still out there and may never be found. In this piece, the killer walked into a police station and said, in Japanese, “sō desu” — that is right — and the case closed. Some of them close. Not because the killers repent. Not because the science alone catches them. But because somebody, usually a family member, refuses to let the case go quiet. And Japan, and any country whose justice system is serious, will keep the door open long enough for that refusal to matter.
This is Namiko Takaba’s story. It is also her husband Satoru’s. It is, more than anything, a story about what one man’s twenty-six years of not-forgetting can force a whole country to eventually confront.
Who Namiko Was
Her name was Namiko Takaba. She was thirty-two years old. She was married to Satoru Takaba, whom she had met and married in her twenties. They had one child — a son named Kōhei, who was two years and one month old on the day his mother was killed. The family lived on the second floor of a small apartment building in Inao-chō, in Nishi Ward, in the city of Nagoya — a residential pocket of Japan’s fourth-largest city, quiet and unremarkable, the kind of place where a young family with a toddler goes to live because rent is manageable and the parks are close and the neighborhood is safe.
Namiko was, by every account of her afterward, a young mother in the specific way that Japanese young mothers of her era were — her days shaped around her son, around the apartment, around meals and errands and her husband’s return from work. She was not famous. She had done nothing to make herself a target. She had not, so far as anyone has ever established, ever met the woman who would eventually come to her door. She was thirty-two and she had a two-year-old and she had a life that was quietly beginning — not the middle of a life, not the end of one, the beginning. That is one of the specific cruelties of this case. She did not lose the middle. She lost the beginning.
Saturday, November 13, 1999. Around 2:30 in the Afternoon.
The murder happened in daylight. That is important. It was around 2:30 in the afternoon on a Saturday. Kōhei, two years old, was in the apartment with his mother. Satoru was elsewhere in the city.
A woman came to the door. We do not know exactly what she said. We do not know whether Namiko recognized her, or whether the woman gave her a reason to open the door that seemed plausible, or whether the door was already unlocked. What we know is that the woman entered the apartment. What we know is that the woman had brought a knife with her, in her bag, from wherever she had come from. What we know is that within a very short time, Namiko was on the floor of the apartment with knife wounds to her neck and torso, and the woman had turned to leave.
In the process of the attack, the killer had cut her own hand deeply on the blade she had brought. She was bleeding by the time she left the apartment. She left the door open. She walked, or ran, from the building, and she trailed her own blood for approximately five hundred metres before the bleeding either stopped or she managed to bandage it. Five hundred metres of a killer’s blood, on a Nagoya residential street, in the middle of a Saturday afternoon, in 1999.
The television in the apartment was left on. Namiko was on the floor. Kōhei was on the kitchen table — awake, aware in the way a two-year-old is aware, physically fine. He did not cry loud enough for the neighbors to hear. He did not know, in the way a two-year-old cannot know, what had just happened to his mother.
The apartment’s landlord, doing whatever landlords do on a Saturday afternoon, came by the building. He found Namiko. He called the police. The first officers on the scene took the child off the table and out of the room. When Satoru arrived home, his wife was dead in their living room and his son was in the arms of a stranger and the whole shape of the life he had just been living had ended.
What the Police Had, and What They Did Not Have
Aichi Prefectural Police worked the case with everything modern Japanese forensics could bring. From the scene they collected the killer’s blood, in significant quantity, on the floor of the apartment and along the five-hundred-metre trail outside. They pulled her DNA. They pulled her fingerprints. They took her footprints. They had a very clear sense of her height, her build, the fact that she was right-handed. They knew she had wounded her own hand during the attack, which meant she was walking around Nagoya for the next several days with a fresh cut on her palm, if anyone knew to look. What they did not have — and this is the whole reason the case sat where it sat for twenty-six years — was a name to compare that DNA to.
Japan in 1999 did not have a national DNA database of the kind the United States or the United Kingdom were building. It still does not, quite — Japanese DNA collection is narrower and more restricted than in most peer countries, for historical and civil-liberties reasons that would take another whole essay to lay out. What the police can do is match crime-scene DNA to a person they have already identified as a suspect and taken a sample from. What they cannot do is drop a profile into a database and get a name back. So the Nagoya police did what Japanese investigators do: they interviewed people. They interviewed and they interviewed and they interviewed. By the twenty-fifth anniversary of the murder, they had spoken to more than five thousand individuals in connection with the case. None of the people they interviewed had ever consented to DNA sampling in a way that produced a match.
The original statute of limitations for murder in Japan, at the time of the crime, was fifteen years. Which meant that the Namiko Takaba case had an official expiration date: November 13, 2014. If nobody was arrested by that day, the killer could never be tried, even if named. The case would go from unsolved to unpunishable.
That deadline is what Satoru Takaba spent the first ten years of his widowerhood fighting.
The Man Who Would Not Let His Wife Go
I want to talk about Satoru now, because Satoru is why we are able to write this piece the way we are writing it. Without Satoru, this case ends in November 2014, unsolved and unpunishable, and Namiko becomes another statistic in a Japan Times year-end retrospective. Because of Satoru, it ends the way it actually ended: with a sixty-nine-year-old woman turning herself in at a Nagoya police station on Halloween 2025.
Here is what Satoru did.
He kept the apartment. The apartment where his wife had been murdered. The apartment where the landlord had found her on the floor. He kept renting it. He paid the rent every month. He kept it kept — not lived-in, but preserved — because the crime scene was still active as far as forensic re-examination was concerned, and because he was not going to be the one who let anything about that scene be lost. He did this for more than twenty-two years. The total rent he paid over those years, out of his own pocket, has been reported by the Japanese press as more than twenty-two million yen — roughly one hundred and fifty thousand US dollars. He was not a rich man. He was a widower with a small son, working a regular job, spending an appreciable fraction of his lifetime income on the preservation of a room where the worst thing that had ever happened to him had happened.
He handed out flyers. Every year, on and around the anniversary of the murder, Satoru went to train stations and shopping streets and public squares in Nagoya, and he handed out flyers with his wife’s face on them, and with a request. Have you seen this woman. Do you know anyone who might have known her. Do you remember a woman with a bandaged hand in mid-November of 1999. He did this year after year, in the same city, to increasingly aging crowds. He gave interviews to any Japanese outlet that would listen. He was quoted, when he was quoted, saying versions of the same sentence: “This is not just about my wife. This is about every case like ours.”
He campaigned to change the law. This is the part I want you to hold onto, because it is the part with the widest circle of consequence. Through the 2000s, Satoru joined and eventually became a leading voice in a movement of victims’ families lobbying the Japanese government to abolish the statute of limitations on murder entirely. He testified. He wrote. He walked corridors in Tokyo. In April of 2010, the Japanese Diet passed exactly the reform he had been asking for: murder now has no statute of limitations in Japan. A killer identified fifty years later can be tried. A killer identified on his deathbed can be tried. The law was, in significant part, pushed through by the accumulated pressure of families like Satoru’s.
Which meant that when November 13, 2014 came — the original expiration date on his wife’s case — it passed without expiring. The case stayed open. And it stayed open because of the very law Satoru himself had helped write. Which is a sentence I want you to read twice. The reason the woman who killed his wife could still be arrested in 2025 is that Satoru had personally helped change the law that would have released her in 2014. He built the door his wife’s killer would eventually walk through.
He was, in the words of his own now-adult son, “stubborn.” That is the word Kōhei used. In Japanese — 執念, shūnen, a stubbornness closer to obsession than to persistence, closer to a vow than to a plan. It is not a light word. Kōhei used it deliberately. His father had spent twenty-six years being stubborn, and it had worked.
The Woman Who Killed Her
I want to tell you about Kumiko Yasufuku now, because her story is the reason this case cracked the way it did, and because it is one of the stranger obsessional trajectories in modern Japanese criminal record, and because it is a reminder that some of the most dangerous fixations in the world do not announce themselves.
Kumiko Yasufuku met Satoru Takaba when they were both seventeen, in high school, in Nagoya, in the mid-1970s. They were in the same tennis club. Satoru remembers her as quiet, ordinary, someone who was there, who was in the club photos, who did not particularly stand out. Yasufuku remembers, we are now told through her confession and through the reporting that has followed, being in love with him almost from the first year they knew each other.
She gave him Valentine’s Day chocolate twice in high school. In Japan Valentine’s Day is asymmetric in a way it is not in the West: it is the day the woman gives the man chocolate, and the man’s response comes a month later on White Day. Yasufuku’s gifts were, by both her account and Satoru’s, unambiguous. They were honmei choco — not the friend-chocolate or the courtesy-chocolate given to colleagues, but the specific chocolate a woman gives the man she wants. Satoru did not reciprocate. She invited him to a café after school in one of the following years and told him, directly, that she loved him. He told her, according to his later account, “I cannot return your feelings.” She cried openly at the table. He got up and left.
After high school, Satoru went to university. Yasufuku did not immediately pass her entrance exams and spent a year as a ronin — the specific Japanese status of a high-school graduate who has failed to enter university and is spending a year re-preparing to take the exams. That year, while re-preparing, she began following Satoru to his tennis practice, uninvited, at his university. She eventually got into Aichi Prefectural University in the city of Toyohashi, an hour and a half from Nagoya by train. From Toyohashi she continued to travel to Satoru’s campus, uninvited, and to appear at places she knew he would be. He rejected her again. She stopped. She was, from that point — the mid-1980s — officially silent for over a decade. She met a man, married him, took his name, worked at various jobs, and lived, so far as anyone knew, an unremarkable Japanese life.
Then, in June of 1999, Yasufuku attended her high school’s alumni reunion (同窓会). Satoru was there. She saw him for the first time in more than a decade. He was married. He had a small child. She spoke briefly with him. He would remember afterward, twenty-six years afterward, that she had seemed to him “透明人間みたいだった” — “like an invisible person”. Faded into the background. Present but not present. That was June.
Five months later, in November, she walked into his wife’s apartment with a knife.
Her stated motive — the one she gave to police in the brief window between her first arrest interviews and her subsequent decision to invoke her right to silence — was that she “disliked” Satoru’s views on “women and child-rearing.” Japanese analysts have treated that formulation with the skepticism it deserves. What the reporting has settled on, and what the psychological writing on the case now largely agrees, is this: Yasufuku’s adolescent love for Satoru had, over the twenty-two years between the café rejection and the class reunion, decayed into a fixed idealization of him as the life she had been kept from having. When she saw him at the reunion, married, with a wife and a son, that fixed idealization curdled — not into rage at him, but into a very focused envy of the woman who had the life she had spent her entire adulthood not having. Namiko was, in the language Japanese analysts have used, “安福の妄想の矛先” — the tip of Yasufuku’s delusion’s spear. It was not personal. It was not, in the ordinary sense, about Namiko at all. Namiko was, in Yasufuku’s worldview, the placeholder in the position she believed she should have been in. And so Yasufuku killed her.
I am naming that logic clearly because it needs to be named clearly. This is one of the ugliest patterns in obsessional violence. It is what happens when someone whose emotional life has been organized around a single unreciprocated attachment for two decades or more cannot metabolize the sight of the other person’s real life. There is no reasonable version of this. There is no version where you can look at Yasufuku’s life and find the crack that explains it. She had a husband. She had a house. She had a job. She had, by every external measure, a functional adulthood. And she carried, underneath all of it, a completely fixed and completely private conviction that Namiko’s life was hers, and she walked into that life on a Saturday afternoon in November and ended it.
The Twenty-Six Years She Spent Ten Kilometres Away
Here is the detail that I keep coming back to, because it is the most quietly unbearable one in the case.
After the murder, Kumiko Yasufuku did not leave Nagoya. She did not flee the country. She did not even leave the city. She continued to live in Minato Ward, an inner ward of Nagoya, approximately ten kilometres from the crime scene. She continued to work part-time jobs. She continued to be married. When Satoru eventually moved out of the murder apartment and into a new home elsewhere in Nagoya, he moved to within two kilometres of where Yasufuku lived. Neither of them knew it, exactly. He knew, because he had told the police his suspicions early on, that she was one of the people worth watching. She knew, because it was her, that he was living almost around the corner from her for two decades. She saw him, sometimes. She saw the flyers he handed out with his wife’s face on them.
She would later tell police that in those twenty-six years she had been “afraid every day”. She could not read the news coverage. She could not talk about it to her family. She was terrified of arrest, and, per her confession, terrified of what her arrest would do to her husband and to her relatives. She lived, in her own account, as a person constantly waiting for a door to be knocked on. In August of 2025, that door was knocked on. Aichi Prefectural Police, after a fresh round of investigative review that had brought her name back to the top of the list, approached her for voluntary questioning. She agreed to be questioned. She refused, initially, to consent to DNA testing. She refused again. She refused a third time. In October of 2025, for reasons she has not publicly explained — possibly exhaustion, possibly a sense that the police had already narrowed things enough that refusal was pointless, possibly the twenty-six-year fear finally cracking — she agreed.
The sample matched the blood on the floor of the apartment where Namiko had died. It matched the trail from the front door out to the street. It matched the fingerprints on the door handle. It matched everything the police had been holding for twenty-six years, and it matched all of it at once.
Yasufuku received the news that the match had come back. The next day — October 31, 2025 — she walked into a Nagoya police station of her own volition and told the officer at the desk that she was there to turn herself in for the 1999 murder of Namiko Takaba. When they formally arrested her and asked her to confirm the allegations, she said, in Japanese, “そうです”. Yes. That is right. Then she stopped talking. She has, since that moment, invoked her right to silence in nearly all subsequent proceedings. On March 6, 2026 she was formally indicted for murder in the Nagoya District Court. Her trial, which will be a saiban-in lay-judge trial — the Japanese equivalent of a jury trial, with six lay judges sitting alongside three professional judges — will begin sometime after pretrial procedures conclude.
The Son Who Was on the Table
Kōhei Takaba is twenty-eight years old now. He does not live in Nagoya anymore. He lives in Tokyo. He has, so far as anyone has ever asked him publicly, no memory of the afternoon of November 13, 1999 — he was two years old, which is beneath the age at which most people form retrievable episodic memory. What he has is his father’s twenty-six years of memory, held on his behalf, carried across a childhood in which his father was quietly and continuously not letting his mother’s case go.
When the news of Yasufuku’s arrest broke, Kōhei took the bullet train from Tokyo back to Nagoya and stood in front of Japanese reporters and said this. His father’s stubbornness — shūnen, the same word again — is what had produced the arrest. And then, addressing his mother directly through the microphone, he said: “まずは一区切り。安らかに眠ってほしい”. A first closure. I hope she can rest peacefully now.
Reporters who saw Satoru that same day said that his face looked, for the first time in twenty-six years, “気持ちが晴れたように見えた” — as though the sky had cleared. It is a phrase you use in Japanese for weather. It is what people said about him. Twenty-six years of a widower’s face, and then one afternoon in November of 2025 it looked, briefly, like weather that had lifted.
The Civil Suit
The criminal case will play out in the Nagoya District Court over the coming years. Yasufuku’s lay-judge trial will produce a verdict; her likely sentence, if convicted — and given her confession and the DNA match, conviction is a near-certainty — will be life imprisonment or a fixed long term of years. Japan does maintain the death penalty, but for a single-victim domestic murder committed by a first-time offender who turned herself in, prosecutors are unlikely to seek it. The strong likelihood is that Yasufuku will spend the rest of her life in prison.
Alongside the criminal case, in March of 2026, Satoru Takaba filed a civil suit against Yasufuku in the Nagoya District Court, seeking damages including reimbursement for the twenty-two million yen he had spent keeping the apartment rented. His stated reason for filing the suit, at the press conference announcing it, was this: “This is not just for myself.” The civil suit is, in the Japanese legal context, both an unusual and a deliberately public act — a widower asking the court to say, on the record, that his killer owes him for the money he spent preserving the room she killed his wife in. It is not really about the money. It is about the record.
What This Case Says to the Other One
I said at the start that this piece is a companion to the Miyazawa/Setagaya piece, and I want to close on why.
The Setagaya case is, as I write this, still open. The man who killed Mikio, Yasuko, Niina, and Rei on the night of December 30, 2000 is somewhere in his mid-forties or mid-sixties, is almost certainly still alive, and has never been named. His fingerprints have been on file for twenty-five years. His DNA has been on file for twenty-five years. It has never matched anything.
The Nagoya case was, as of one year ago, in exactly the same position. A killer’s DNA on file for twenty-six years and matching nothing. A widower who would not let the case go quiet. A law — the very law that keeps Setagaya legally prosecutable, the 2010 abolition of the statute of limitations on murder — that had been pushed through in part by the same widower’s own advocacy. And then, in October of 2025, a woman consented to a DNA test, and the entire twenty-six years collapsed into a single afternoon at a police station.
This is what I want you to sit with. The Setagaya killer is out there. He is somebody’s neighbor. Somewhere in Japan, or somewhere in South Korea, or somewhere on an American military base overseas, there is a man in his sixties with a scar on his right palm and a Y-chromosome haplogroup that would light up the Setagaya file the moment it entered a database. There is, quite possibly, a woman who has spent the last twenty-five years wondering. There is possibly a son. There is possibly a granddaughter. Somewhere, somebody has the shape of what he did. And somewhere — on some ordinary autumn afternoon that has not happened yet — that person could walk into a police station.
Cold does not mean dead. Namiko Takaba’s case sat cold for twenty-six years. Her husband, Satoru Takaba, spent one hundred and fifty thousand US dollars keeping her apartment rented; walked the same Nagoya train stations every year with her photograph in his hand; helped write the law that kept his own wife’s case legally prosecutable past the day it was originally scheduled to expire; and on the afternoon of October 31, 2025, took the phone call telling him that the woman he had privately suspected for two and a half decades had just walked into a police station and confessed. He said he was shocked. He said, of the twenty-six years, that it had never been about stubbornness — that he had just been doing what a husband does when his wife has been killed and nobody knows who did it.
His son, twenty-eight years old, born to a mother whose face he cannot remember, called it stubbornness anyway.
Say her name once, please, before you close this tab. Namiko Takaba. She was thirty-two. She had a two-year-old son. She was killed in her own living room by a woman she had never met, over a man who had never chosen the woman doing the killing. Her husband spent the next twenty-six years refusing to let her be forgotten. Her killer will spend the rest of her life in prison. Her son grew up. The apartment where she died was, at last, given back to the landlord. Everything that could still be done for her, in the years after she was killed, was done for her.
That is the ending some of these cases get. Not the one they deserve, because there is no ending they deserve — the one they deserve would be them never having happened. But the ending they can, sometimes, with time and stubbornness and law, actually receive. Somewhere in Tokyo tonight there is a young man in his late twenties who is his mother’s son. Somewhere in Nagoya there is a sixty-nine-year-old widower who is still, at last, on his wife’s side of the earth. And somewhere in Japan there is a man in his sixties whose past is still, for now, waiting.

If you are reading this from Japan and you know something about an unsolved case, the twenty-six years of the Namiko Takaba investigation are proof that a tip is never wasted. Aichi Prefectural Police maintains an active public information line for cold cases. Cold, as her family would tell you, is not dead.
