Suzuka Hatakeyama killed two children in the town of Fujisato, in northern Akita Prefecture, in the spring of 2006. On April 9 she dropped her nine-year-old daughter, Ayaka, from a bridge into a river. Police soon concluded that the girl had fallen in by accident. On May 17 she lured Goken Yoneyama, a seven-year-old first grader who lived two houses away, into her home on his way back from school and strangled him. Fujisato had just over 4,000 residents, The Japan Times noted, and the two deaths, about five weeks apart, drew national attention to the town.
The case became a national story in Japan for several reasons at once. Hatakeyama had spent the weeks between the deaths insisting, loudly and in public, that her daughter had not died by accident. After the boy was found, reporters and camera crews surrounded her for weeks before her arrest, and she was filmed shouting at them. The early accident ruling on Ayaka's death drew criticism in Japan's parliament, and the National Police Agency later said the Akita police should reflect sincerely on it. At trial, prosecutors sought the death penalty. The Akita District Court sentenced her to life imprisonment in March 2008, finding that both killings were intentional but neither was planned. Her own Supreme Court appeal, filed and then withdrawn, left that sentence final in May 2009.
Her parents' home was in Futatsui, near Fujisato. The house no longer stands; a man who worked for her father's company told the writer Ikko Ono in 2023 that the land had been set aside for an expressway.
She described her childhood in court in October 2007. She testified that her father had physically abused her and that she was bullied at school, where children called her "germ" in elementary school, The Japan Times reported. Hirokazu Hasegawa, a clinical psychologist who worked with her defense team on appeal, wrote in the magazine Bungeishunju in 2010 that a second-grade teacher had told her a spirit was attached to her, after which classmates gave her a nickname meaning "spirit photo." He wrote that she could not finish school lunch in the time allowed, that a teacher made her eat in a humiliating way, and that she bore this without telling anyone. He described a home with a violent father and a daughter who often said she did not want to drag her family into her troubles.
By the time of the killings she was divorced, living on welfare, and raising Ayaka alone in a detached house on a housing estate in Fujisato, with no other adult in the home, according to The Japan Times and the journalist Yoichiro Aonuma, who covered her trial. From about December 2003 she had been seeing a psychiatrist at a general hospital in Noshiro, Ono reported in 2024. A childhood friend who saw her in the hospital waiting room the year before the killings told him that Hatakeyama's whole body had suddenly shaken for about ten minutes, and that she said this happened sometimes. A man who worked at her father's company told Ono that she took prescribed medicines, including antidepressants and sleeping pills, in far larger amounts than prescribed. In its opening statement at her trial, the defense said she had decided to end her life during the Golden Week holidays in 2005 and had taken stored-up medication, but not enough to die, and that thoughts of trying again stayed with her until her daughter's death.
Ayaka Hatakeyama was nine years old and in the fourth grade at the local elementary school, which Goken Yoneyama also attended. She had come to the school as a transfer student, her mother later wrote in a diary.
The trial record painted a mixed picture of her home life. Aonuma recalled testimony that she often arrived at school late and in tears, saying her mother had overslept, and that her clothes were often unwashed. Neighbors told reporters in 2006 that there were signs the girl was not given enough to eat, The Japan Times reported. Yet a shopkeeper near the family's home, who sold Ayaka the instant noodles she bought on her last visit, told Aonuma during the trial that she depended on her mother completely, and that her mother cared for her and came out to meet her when she was late home after dark. "For Ayaka, there is only Suzuka," he said.
On the evening of April 9, 2006, Hatakeyama took Ayaka to Osawa Bridge, which crosses the Fujikoto River about 2 kilometers from their home. At about 6:45 p.m., according to the police case later set out in The Japan Times, she dropped the girl from the bridge into the river. That same evening she reported Ayaka missing. She told police at first that her daughter had disappeared in the afternoon after going to a friend's house.
Ayaka's body was found the next afternoon, April 10, in the Fujikoto River, a tributary of the Yoneshiro.
Police announced that the girl appeared to have slipped down a riverbank while playing and drowned, The Japan Times reported. The government later set out the reasoning in a formal answer to parliament. An autopsy and examination had found no unusual injuries that suggested a crime. A police dog had followed her scent to the riverbank near her home, there were marks suggesting that someone had slipped down the bank, and the river held enough water to carry her away. On that basis police concluded that she had probably fallen in and been swept downstream. Because they believed it was an accident, they returned her clothing to her mother after examining it, and they did not go door to door in the Kasuge district of Fujisato or the surrounding area.
Hatakeyama did not accept the ruling. She telephoned the police repeatedly asking them to reopen the case, handed out fliers asking residents for information about where Ayaka had last been seen, and asked television stations to help uncover the truth, The Japan Times reported. Aonuma recounted that she went to the Noshiro police station in anger, kicked a wall there, and told the media that her daughter's death was not an accident. A Jiji Press photograph published with Hasegawa's 2010 article shows one of the fliers she made asking whether anyone had seen her daughter.
Goken Yoneyama was seven and in the first grade. He lived two houses from the Hatakeyamas, and he and Ayaka attended the same school. He was the second of three children.
On the afternoon of May 17, 2006, Goken left school at about 3 p.m. with four friends, The Japan Times reported. Near his home he parted from the last of them, saying he was going home and would see them later. He never arrived. When he did not come home, his parents reported him missing.
The next afternoon, May 18, a man out jogging found Goken's body in grass near the bank of the Yoneshiro River in Noshiro, about 8 kilometers from his home and about 2 kilometers downstream from where Ayaka had been found. He had been strangled. Police dogs could not trace his scent from a park near his house, which led investigators to believe he had been taken away by car, and there was no sign of a struggle where he lay, suggesting that he had died elsewhere. An autopsy put the time of death between 4 p.m. and 6 p.m. on May 17. Police said they would look again at Ayaka's death to see whether the two were connected.
What had happened, Hatakeyama later admitted, was that she saw Goken near her home that afternoon, called him into her house and strangled him at about 3:30 p.m., then drove his body to the riverbank.
From May 18 reporters and camera crews followed Hatakeyama wherever she went, and she was seen shouting at them, The Japan Times reported. Some weekly magazines came close to naming her as the killer before any arrest. The headline of Ono's 2023 article on the case quotes her yelling at a camera crew that she had told them not to film.
On May 24 she contacted the Broadcasting Ethics and Program Improvement Organization (BPO), the broadcasting industry's independent watchdog. According to the request its human-rights committee issued the next day, she said the coverage had become so intense after Goken was found that dozens of vehicles surrounded her house and she could not live there. Reporters had also besieged her parents' house, where she had taken refuge, so that she could not go out or open the windows, and they followed her to work. She was afraid that Ayaka's burial, planned for Saturday, May 27, could not go ahead, and asked the committee to "please do something." On May 25 the committee strongly urged broadcasters and other media to report with restraint and not to rush after the facts in ways that violated the privacy of the people involved. A group of 15 newspaper and broadcasting companies in Akita also drew up its own reporting guidelines. Yasuhiko Tajima, a professor at Sophia University, told The Japan Times that these steps had some effect but came late, and that the press had fixed too narrowly on whether she would be arrested instead of examining the police investigation.
Police found traces of blood and urine believed to be Goken's in Hatakeyama's house and in the trunk of her car, evidence that he had been killed in her home. On June 4, 2006, she was arrested on suspicion of abandoning his body. She was 33.
On June 25 prosecutors indicted her for abandoning the body, and police served a fresh warrant the same day, arresting her on suspicion of murdering the boy. She had admitted, police said, to luring him into her house and strangling him. Her explanations shifted. According to a Japan Times editorial in July, she had at one point said she was jealous that Goken was alive and well while Ayaka was dead, and later said she had reasoned that the death of another child would make people believe Ayaka, too, had been killed by someone. On July 17 she was indicted for Goken's murder.
Her account of her daughter's death also changed. After the arrest for Goken's death, she first told police that Ayaka had fallen from Osawa Bridge by accident on the evening of April 9. In early July she told them she had pushed the girl. Ayaka had wanted to see the fish she had read about in her comic books, she said, and when none appeared the child became a nuisance and irritated her. She was said to have trouble recalling what happened.
On July 18, 2006, police arrested her for the third time, on suspicion of murdering her daughter. The Akita police held a news conference at 2:15 that afternoon, attended by about 110 reporters and camera crews, Ono reported; the head of the prefectural criminal investigation department answered most of the questions and announced that she had been arrested at 1 p.m. on suspicion of murder. Asked repeatedly whether the investigation had been handled properly, police said they had been investigating Ayaka's death as both a possible crime and a possible accident. Hatakeyama was later indicted for her daughter's murder.
The arrest turned the April accident ruling into a matter of national debate. A Japan Times editorial in July 2006 called the first investigation apparently shoddy. Local residents had found it strange that the body was found so soon, given two low weirs between the supposed point of the fall and the place where she was found. The editorial argued that closer attention to the evidence might have led police to Hatakeyama sooner and prevented Goken's death. It also noted that had she stayed quiet, public interest in her daughter's death would probably not have revived.
Goken's father filed a complaint with the Akita Prefectural Public Safety Commission, the civilian body that oversees the prefectural police. In a reply dated November 9, 2006, the commission said that judging the death an accident, and the investigation built on that judgment, had not necessarily been sufficient and were matters for reflection, and that it would urge the police to apply the lessons. It also acknowledged that the police had not carried out the routine household visits their own 1999 standard called for in the district.
On November 24, 2006, Sumio Mabuchi, a member of the House of Representatives, submitted a written question to the cabinet about the case. He argued that findings reported after the arrest should have made the accident ruling untenable, and that a proper early investigation might have saved the second child. The cabinet's answer, issued in the name of Prime Minister Shinzo Abe on December 5, 2006, defended the autopsy and examination as properly conducted but conceded that the accident conclusion "turned out to differ from the facts." The National Police Agency, it said, considered that the accident judgment and the investigation based on it had not been sufficiently thorough and that the Akita police should reflect sincerely on this. The agency had directed the prefectural police, in future cases, to review all available material comprehensively before setting the course of an investigation, and to assign adequate staff.
The trial opened at the Akita District Court on September 12, 2007, and ran to 14 hearings. On the first day Hatakeyama denied that she had ever resolved to kill her daughter. She admitted killing Goken, saying there was no mistake about it, but said she did not know whether her state of mind at the time had been normal. Her lawyers argued that Ayaka's death was an accident and that she had diminished capacity when she killed the boy. In the defense's account, the girl had insisted on going to see salmon, Hatakeyama had let her climb onto the bridge railing, and when the frightened child turned to cling to her, she brushed her away and the girl fell. Prosecutors argued that she had come to resent her daughter and killed her deliberately, and that she later killed Goken to draw attention back to herself after police and the public stopped listening to her claims.
Goken's parents attended the hearings, holding his photograph. In her opening remarks Hatakeyama apologized to the families and said she hoped the Yoneyama family would see over the course of the trial how much she had changed.
On October 29, 2007, she spoke in court about the abuse and bullying of her childhood. Asked about her relationship with her daughter, she said she had not liked touching Ayaka's hands because they were sweaty, The Japan Times reported. On October 31, asked what punishment she deserved, she said the punishment the Yoneyama family wanted was only natural; asked by her own lawyer whether that meant atoning with her life, she wept and said she could think of no other way. At a hearing on November 12, she said that if she were sentenced to death she would not appeal. Aonuma, who watched these hearings, noted the contradiction: she said she wanted the severest penalty, while her lawyers' arguments, if accepted, ruled it out. She also told the court that her interrogation had been illegal and that fear had led her to sign statements under pressure.
At one hearing a life-size model of the bridge railing was brought into the courtroom for a reenactment. Hatakeyama began to tremble so violently that she could not stand, and the presiding judge halted the proceedings, Aonuma wrote.
A court-ordered psychiatric evaluation ran alongside the trial. The examining psychiatrist asked Hatakeyama to write freely in a notebook, and her entries, kept for about two months beginning ten days after the first hearing, were later submitted as evidence. In one entry she disputed testimony by Ayaka's homeroom teacher that she had come to only two school events, insisting she had attended every class observation day and parent meeting in the first two grades. In another, dated October 21, 2007, she wrote that she felt regret toward Goken but not the guilt she felt toward Ayaka, that she did not understand why his parents were so angry, and that they still had two other children. In November she called the prosecutor a pitiful man and wrote that if she could not go home to her family at once, she wanted to die.
The psychiatrist diagnosed a personality disorder and traced it to violence by her father in adolescence and an overly close relationship with her mother, Ono reported in an article republished by livedoor News. The report also said she tended to accept too easily what was written in her statements. Prosecutors argued that her symptoms fell within the neurotic range and that she was fully responsible for her actions; the defense argued diminished capacity. A Sankei Shimbun book reproducing the full trial record notes that neither side accepted the evaluation.
In their closing arguments, prosecutors asked for the death penalty. The defense asked for a fixed prison term.
On March 19, 2008, the Akita District Court sentenced Hatakeyama, then 35, to life imprisonment. The court found that she had intended to kill both children. It found that she tended to feel her daughter's presence as a burden; that when Ayaka said she wanted to see fish from the bridge, she grew irritated, placed the girl on the parapet and pushed her; and that she made no attempt to save her after she fell, out of what the court called a selfish wish to be free of a parent's responsibilities. The court described the relationship between mother and daughter as beyond comprehension, The Japan Times reported. It acknowledged that a psychological mechanism suppressing her memory might have been at work after Ayaka's death, but held that she bore full criminal responsibility.
The court declined to impose death because it found that she had acted on impulse and that neither killing was planned in advance. In closing, the presiding judge added a request about any future parole: that those deciding it bear in mind the gravity of her crimes and that her self-reflection stayed on the surface, a trait of character not easily changed.
As the hearing ended, Hatakeyama asked the judge for permission to speak, knelt in the courtroom and apologized to Goken's family for taking their precious child. Less than an hour after the sentence, she appealed, Aonuma reported. Prosecutors appealed as well.
The appeal was heard by the Sendai High Court's Akita Branch from September 2008. Hasegawa, the psychologist, was asked by the defense to examine her statements and met her repeatedly in the detention center. He wrote that the High Court first said it would accept his personality assessment and later declined it after prosecutors objected.
On March 25, 2009, the court, presided over by Judge Toshinori Takehana, upheld the life sentence and rejected the appeals of both the prosecution and the defense. It confirmed the finding that Hatakeyama had intended to kill her daughter, J-CAST News reported. She was 36.
Prosecutors decided not to take the case to the Supreme Court. According to Aonuma, Hatakeyama had decided not to appeal either, but on the morning of the deadline, after learning that prosecutors had given up, she suddenly asked her lawyer to file one, to the surprise of her own defense team. About a month and a half later she withdrew it herself, and the life sentence became final in May 2009.
During the first trial Hatakeyama was held in the detention facility of Akita Prison. She is serving her sentence at the Fukushima Prison branch in Fukushima Prefecture, Ono reported in January 2024; he gave the same location, and her age as 52, in August 2025.
In April 2026 Gendai Business, a Kodansha publication, carried an interview with a former inmate who had served two terms at the Fukushima branch. She said Hatakeyama was already there on her first term and still there on her second. On the first occasion, she said, Hatakeyama looked hard and was spiteful toward other prisoners; by the second she had a calm, gentle face and held a post assisting the guards, in which she looked after newly arrived inmates closely. These are one former prisoner's recollections. The same article noted that Japan's new unified custodial sentence, which removed the obligation to work, took effect on June 1, 2025.
No source opened in this check reports a release, a parole hearing, a request for a retrial or her death. When last reported, in August 2025, she was serving her life sentence.
The Hokuu Shimpo, a local newspaper in the Noshiro area, ran a series on the case for two years from April 2007, attending every hearing of both trials and publishing 125 installments, the Japan Newspaper Association's journal reported in April 2009. In a special article on the opening day of the trial, the paper acknowledged that it had first reported Ayaka's death as a possible accidental fall and reflected on the overheated pack coverage after Goken's death. Its last appeal article concluded that the truth of the case had still not been established.
When Ono visited Fujisato in 2023, the house where Hatakeyama had lived with Ayaka had been torn down and the lot stood empty, overgrown except along one edge, where sunflowers had been planted at regular intervals. One resident told him she had finally managed to forget and did not want to remember; another said that 17 years had gone by in no time.
The journalist Satoshi Kamata wrote Hashi no Ue no "Satsui" ("Intent to Kill" on the Bridge), subtitled "How Suzuka Hatakeyama Was Judged," published by Heibonsha in June 2009 and reissued in revised form by Kodansha in 2013. Its publisher describes it as asking whether she truly intended to kill, examining her hard upbringing and flaws in her trial, and offering an account that differs from both the prosecution and the defense. A revised edition appeared in January 2026 in a collected volume of Kamata's work from Koseisha. The Sankei Shimbun's social affairs department published a 637-page book in April 2008 reproducing the questions and answers from every hearing of the first trial. Aonuma wrote about the trial in a book on 21 death-penalty cases he had watched, and Ono returned to the case in a four-part series in 2023 and 2024 and in later articles drawing on her trial diary.
Whether Ayaka's death was intentional. Hatakeyama has denied that she meant to kill her daughter since the first day of her trial, and her lawyers argued it was an accident. Both the Akita District Court and the Sendai High Court found that she intended to kill. The conviction for Ayaka's murder is final.
Her memory. A court-ordered evaluation recognized dissociative amnesia, Ono reported, and the trial court accepted that her memory might have been suppressed after Ayaka's death, while finding her fully responsible. Hasegawa, the defense psychologist, went further. He wrote that she was not lying, that the memories he drew out in two sessions differed entirely from her police statement, and that the statement that she pushed Ayaka from Osawa Bridge was "clearly a composition." He set out his own theory that she caused the death by accident elsewhere and moved the body. These are his views; the courts did not accept them.
Where Ayaka died. A longtime local angler told Ono in 2023, as he had in 2015, that the water was so low that spring that a body could not have drifted from Osawa Bridge past four shallow stretches to where Ayaka was found without visible signs of it. Hasegawa raised similar doubts. The courts accepted the confession that placed the killing at the bridge.
What police said to her. Hasegawa wrote that a police officer had told her that an accident would be easier on her as a mother. This rests on his account alone.
Motive. Prosecutors and the defense offered different explanations of why she killed Goken, and her own accounts changed. Hasegawa wrote that the true motives for both killings have never been disclosed, and the Hokuu Shimpo concluded in 2009 that the truth had not been established.
Disputed testimony at trial. Hatakeyama's diary disputed a teacher's evidence about her attendance at school events and about whether Ayaka was bullied at school; the truth of those points is not known.
