For three months, eight girls disappeared in Japan. They were united by a desire to commit suicide, but the matter was more complicated than at first glance

On October 23, 2017, 23-year-old Aiko Tamura from the suburbs of Tokyo Hatioji last time answered a message in the messenger. Her brother, with whom they corresponded almost every day, continued to write her messages, but the Aiko account was no longer online. She also did not appear at home for the second day.
The brother scored an alarm , turned to the police and announced the loss. He had reasons to worry. For the past few years, life threw a test for a test for the family, and this has been affected by Aiko's emotional state. She was persecuted by thoughts of suicide. It turned out that his brother was worried not in vain.

As a child, Aiko Tamura was an active child: she went in for sports, looked after rabbits at school and even played in the orchestra. However, everything changed dramatically when her mother moved from Jokogama to Hatioji with her children - she ran away from her husband, who brutally treated her.
The family lived on benefits in the apartment, which was helped by the social service. After moving, according to acquaintances, Aiko closed in herself and began to miss classes at school.
In 2017, Aiko's mother died, and she began to communicate more with her brother. On her twitter, the death posts began to appear more and more often. Once she even wrote that "she is looking for someone who would end life with her."

By the time Aiko Tamura, the police investigated the disappearance of several other people, mainly young women in the fall of 2017. The 17-year-old Akari court in 2017 was a graduation student of a high school, dreamed of drawing manga and led an art club. At the same time, judging by the posts on social networks, the court felt unhappy. Like Aiko Tamura, she wrote on Twitter that she wanted to commit suicide.

On September 26, 2017, she attended a school sports event in Fukushima, after which she disappeared. Her friends said that the next day she left their group chat in Line messenger. Later on the same day, her mobile phone stopped giving a signal.
The police began to look for the court. They used special search methods, such as tracking the mobile phone signal of missing. But the signal was interrupted at a certain moment, and it was impossible to establish the exact location of the device.
On October 26, three days after Aiko for the last time she got in touch, her brother, having never received any information from the police, decided to seek help from the sister's subscribers.
He knew that Aiko used the same password in different accounts, and was aware of which one. Having logged into the Twitter sister account, he published several posts with a call for help. “The last time I was able to contact the owner of the account, that is, my sister, October 23. Before that, we corresponded almost every day to Line. But in the morning of October 23, at about 9 o’clock, she stopped answering, ”he wrote.

In addition, Brother Aiko decided to study the sister's correspondence. He found messages from a stranger who offered his sister to meet. This find became a turning point in the case. Brother Aiko investigated the man’s account and realized that he often writes to different women. The general topic that united these correspondence is talk about death.
Brother Aiko told the investigation about what he managed to find out, and provided the police with information about the girls with whom the man contacted on Twitter. Thanks to this, the police were able to understand the reason for the loss of Aiko and, as it turned out later, another eight people, including Akari courts.
The police turned to one of the interlocutors of that man - the Japanese mediacalled her Yumi. She helped the police lure the man to meet on October 30, 2017. Police traveled a man to his apartment in the city of Dzam and burst inside.
When the police were in the suspect’s apartment, a room full of storage boxes appeared in front of them, from which a strange smell emanated. Inside the containers there were a large number of divided bodies placed in refrigerators, as well as nine heads and about 240 human bones.
The police seized ropes , saws and other tools used in the commission of crimes, as well as sleeping pills that were given to the victims.

There were reports on the Internet that there was a modular bathroom in the apartment, where a man, supposedly, was divided into his victims. “Some parts of the bodies were found in a portable refrigerator covered with a filler for a cat toilet,” one of the police officers later said .
The owner of the apartment was immediately detained. It turned out to be 27-year-old Siraisis Takahiro. He did not make excuses. “I killed nine people since I moved to the apartment on August 22,” the police quoted him.
Subsequently, on video surveillance cameras in this area, they saw Aiko Tamur along with a person who looked like Sirai. The police later said that he strangled Tamur on October 23, 2017.
The investigation remained to answer the question: why did Takakhiro commit murders?
Siraisi Takakhiro was born on October 30, 1990 in the city of Matida in the Prefecture of Tokyo. After the birth of the younger sister, the family moved to a private house in the city of Dzam in the Kanagawa Prefecture. Takahiro's father designed automobile details, the mother raised children.
According to his mother Takahiro, in childhood he was a closed child. In the kindergarten football section, he was almost not given passes during the games, and he quickly threw out classes. Having become a schoolboy, he became interested in video games, but did not follow an agreement with his parents to play only two hours a day, because of which they often quarreled. At the same time, according to the mother, the family was ordinary, and, despite the disagreement, they went on travel once a year.

From the third grade of secondary school, according to his mother, Takahiro often began to miss classes, since “there were only strong and stubborn children in the class, with whom he could not find a common language,” and conducted all the time playing video games in a cluttered room.
After graduating from high school in 2009, Takahiro did not continue his studies. By that time, his parents divorced : his mother left home, taking her younger sister. He went to work in a local supermarket and worked there before dismissal in 2011. Then he worked part-time in different places, for example, in Patinka bars (institutions with slot machines) of the Kanagawa prefecture.

Subsequently, Takakhiro moved to work in Tokyo. Formally, he got a job in a company that helped young women with work, but in fact she sent them to the brothels of the Japanese capital. He was a street scout and tried to lure the girls to work in clubs in the largest area of the Red Lights of Tokyo.
In 2017, he was detained for violation of the law on labor activity. He received a suspended term for bringing a woman to a sex shop, being aware that later she would be involved in prostitution. Because of the sentence, Takakhiro had to return to his hometown of Dzam and live with his father, working in a warehouse.
As Takahiro himself later said , he did not like such a life. He did not get along with his father and wanted to move out as soon as possible. To do this, he decided to find a woman who would provide him, and began to get acquainted with the girls on the Internet. Takahiro chose women with depression and suicidal thoughts. The work with a scout in the sex industry, according to him, taught him that "women with suicidal inclinations are easier to control."
In March 2017, he started an account on Twitter. In the profile description, he wrote : “I want to help people who really suffer. Please write to me in private messages at any time. ” Subsequently, Takakhiro used five different accounts on Twitter, including @hangingPro, from which Aiko Tamura probably wrote (now these accounts are blocked).

On Twitter, Takakhiro began to publish posts associated with suicide. Subsequently, it said that he was not going to commit suicide and it was only a way to attract women. At the same time, if he noticed other accounts on Twitter, where there were posts about suicide, Takahiro began to communicate with the user through private messages.
The investigation established that in early August 2017, Takakhiro met with 21-year-old Mizuki Miura. She lived in the city of Asugi (located in the Kanagawa Prefecture, about 50 kilometers from Tokyo) along with her mother and older brother in a small apartment. Miura told him that she wanted to commit suicide. Takakhiro called her to meet. Soon he invited Miura to live together, suggesting: "We will die together." Miura agreed and paid him 510 thousand yen (about 4.6 thousand dollars at the rate for 2017) - her share for the rent for several months. Already on August 22, they rented a two -story apartment.
The day after the start of life together, Takahiro attacked Miura. He pushed her when they walked behind the house, and strangled her in advance with a prepared rope. According to Takahiro, Miura resisted and did not want to die. Takakhiro abused her body and took all the money that the girl had. To destroy the evidence, Takahiro dismissed the body, placed his head in the refrigerator, and threw the rest of the body. The police were looking for a girl, but could not establish where she moved and with whom she contacted after that. As a result, Miura was listed as missing.
Subsequently, Takakhiro said that he first thought about the murder when he found out how much money was stored on Miura, transferred, as he thought, from her young man. Then he began to look for information on how to kill, how to dismember the body, how to get rid of it, how to hide the evidence. Even before calling Miura to a rented apartment, Takahiro bought a saw.

Five days after the murder, on August 28, Takahiro, after correspondence on social networks, invited his youngest victim home-a 15-year-old schoolgirl Cureh Ishihar . He raped the girl, after which he killed, dismembered her body and took her things. Two days after the death of Ishihara, on August 30, the only man was killed as a victim in this case, Heo Nisinake, a friend of the murdered Miura.
According to some reports, he was her boyfriend, but one of his friends subsequently doubted this. According to him, Nisinake and Miura "just met in a group of suicids." Prior to this, in June 2017, Nisinake broke up with a girl with whom he met a couple of years. “He was very worried, the doctor diagnosed“ Depression ”, prescribed psychotropic drugs. Then he began to communicate on Twitter with other suicidally tuned people. A few days before his disappearance on August 29, he said that he had already tried to commit suicide with one of them twice, ”said Nisinake's friend.
After the disappearance of Miura, Nisinake became interested in Takahiro if he knew where she was gone. Takakhiro promised to tell everything that he remembered about their last meeting, and called Nisinake to himself. When he came to visit, Takahiro killed him, fearing the exposure.

The murders continued from August to October 2017. Three people were killed in August, four in September and two more in October. Among the victims were the 17-year-old high school student Natsumi Kubo and a 19-year-old student at the University of Khinako Sarasina, both natives of the prefecture of Saitama, as well as 25-year-old Kazumi Maruama, who worked in the store. All of them thought about death and wrote about it on social networks.
Three more women were lucky: despite their acquaintance with Takahiro, they survived . With one of them he met for two months, thinking that money can be received from her. She treated him and paid for the hotel. He allowed the second woman to live for 10 days, and she gave him money for everyday expenses. He tried to seduce the third, but, in his own words, he lacked charm, and in the end she just left. He thought about what he could rape and kill her, but in the end he let go.

In order not to open him, Takahiro carefully masked the murders. In particular, he was concerned that there was no smell from bodies. “If you drive the“ smell of decomposition ”, a bunch of information appears. They say that the bleach or cat filler helps ... I tried everything as it is written, ”he said , admitting that these“ methods ”did not help him very much. The strongest smell appeared, according to him, at the time of opening the abdomen. How to divide the corpses, he also searched on the Internet. The smell was still, but the neighbors did not beat the alarm.
Takakhiro used five different accounts on Twitter, which made it difficult to capture. And due to the lack of a connection between the majority of the victims, it was also difficult for the police to tie the loss among themselves.
After the DNA identification of the bodies of the personality of all dead were established. In parallel with this, the interrogation of Takahiro began. After all the necessary procedures, Takakhiro was charged with forcing sexual intercourse, robbery and murder, as well as abuse of bodies.
During the court, Takahiro pleaded guilty. “There is a lot of evidence and protocols, everything is securely recorded,” he said . - If you soberly assess the situation, it is clear that even if you fight, nothing will change. So, I think, it’s better to recognize everything and calmly accept everything. ”

However, his lawyers insisted that the victims themselves wanted death. The client, as the defense claimed, has "some kind of mental disorder, presumably, the loss of reason or mental exhaustion." It was assumed that these arguments would help to soften the sentence.
However, psychological examination recognized Takahiro as sane. The argument that the victims themselves wanted to die, the court rejected the court due to the information received during the investigation. According to her, although eight women were attracted by the topic of suicide in communicating with Takahiro, some of them expressed the desire to “live well”, besides, the victims resisted when they were killed. Takakhiro himself admitted in court: these murders were not pre -agreed by the parties. When the prosecutor asked : "Did she [the victim] on the day of the murder:" Kill me "?" - Takahiro answered: "No." And to the clarifying question: "Are you sure that there was no consent?" - He firmly said: "There was certainly not."
Takahiro remained calm. When asked if he feels guilty, he said that at first when he killed the first victims, he felt a little guilty, but later this feeling subsided. Takakhiro also said that he would like to marry, so that someone could visit him while he was in custody.
On December 15, 2020, the court announced the verdict. He indicated that Siraisi Takakhiro used the term “suicide” to systematically lure mentally unstable victims into his apartment. His methods were insidious and dodgy, and he continued to commit murders in order to satisfy his sexual desires and receive money. Takahiro sentenced to death.
He did not dispute the verdict. “It doesn’t matter if they will be sentenced to death,” he said the day before. “Just finish the process as soon as possible and let me live calmly.” After the death sentence, Takakhiro gave a lot of interviews to reporters and representatives of the NGO. “I expected to feel something. But, in a strange way, he did not sweat, the heart did not pound. I already knew everything very well in advance, ”he described his emotions after the sentence.
Siraisi Takahiro was executed on the morning of June 27, 2025. He was 35 years old.
