The Amagasaki Serial Murder Incident (尼崎連続殺人事件) was a 2012 several serial murder and body dumping case, in which family households in Japan were tortured continuously for more than 25 years.[clarification needed] The crimes began with the disappearance of a woman in or around 1987. At least 8 victims were confirmed to have died, mainly as a result of assault, confinement and other forms of abuse.[1] The crimes were committed mainly in Amagasaki, but also in six other prefectures, Hyogo, Kochi, Kagawa, Okayama, Shiga and Kyoto.[2]
The incident was discovered when the suspects Miyoko Sumida (角田美代子) and Masanori Sumida (角田正則) were arrested in November 2011. The cousin of the ringleader received a life sentence over the Amagasaki murders.
Overview
For at least 25 years, the woman believed to be the main suspect of this case had been living together with many others in the southeastern area of Amagasaki City, Hyogo Prefecture, building a pseudo-family not related to her by blood.[3] Although several suspicious deaths and disappearances had occurred one after another around 1987, starting with the disappearance of Woman A, the case would not come to light for many years.
However, in November 2011, a woman in her 40s who had been held captive escaped from confinement and ran to the police. Sumida was arrested on suspicion of assaulting Kazuko Oe's eldest daughter following her death. Furthermore, this case allowed for the investigation to further advance, and a series of other incidents came to light when an accessory from a separate case, who had been arrested in October 2012 (the theft of C's mother's pension), fully confessed to the crime. Shortly after, in December 2012, Sumida committed suicide at the detention center of the Hyogo Prefectural Police Department without saying much about the incident.
A joint investigation by the Hyogo, Kagawa, and Okinawa prefectural police, which had been investigating the cases based on the statements of X's accomplices, was disbanded in March 2014, which effectively ended the investigation. Eleven people, including X and her relatives, were indicted on charges of manslaughter and murder for six of the eight confirmed deaths. Trials were held for only ten of the relatives as X had committed suicide in jail. The whereabouts of three people who were close to X are still unknown. One was allegedly killed by X but the body was never found, and the other two are missing but their information was made available to the public [citation needed].
Among the numerous mass murder cases in Japan, one notable feature of this particular incident is the high number of individuals arrested and referred to prosecutors, totaling 17. It was later revealed that during the "family hijacking", Sumida would take advantage of minor weaknesses and intimidation tactics to control entire families. It was also revealed that many of the victims were subjected to forced violence against their relatives, were restricted from eating, drinking, and sleeping, and were even deprived of their property and forced to break apart their families. Many of the arrested and documented persons who were taken in by X as members of her pseudo-family were also forced to be involved in the crimes. In addition, many of these members ended up becoming relatives either through forced marriages or adoption [citation needed].
Persons Involved in Incident
(List of those who were arrested, prosecuted, deceased, or claimed as a missing person.)
Main Culprit X (Arrest & Death)
- Born in 1948.[4]
- On December 12, 2012, she committed suicide in a detention center at the Hyogo Prefectural Police Headquarters. She held absolute power within her pseudo-family, forcing her cohabitants to swear their loyalty and sanctioning those who disobeyed her. She would also take them on trips and outings. Some would take this opportunity to escape but would be persistently sought out and brought back.[4]
- She was charged with one account of manslaughter, but the charges were dismissed due to the nature of the death. However, following her death, she was charged for the manslaughter and murders of her eldest son, second son, and eldest daughter among other charges.[4]
X一"Family"
A "family" formed through repeated adoptions with relatives in the course of X's multiple "family takeovers", none of whom are related by blood.
- X's Sister-in-Law H (A's oldest son's registered wife) 【Arrested】
- Born in 1953.[4]
- They had known each other since childhood since H's mother had been renting a room from X's mother, where they had lived together for several decades.[5] She was adopted by X's mother in 1988.
- According to H's own testimony, X would often yell at H's parents and forcibly separated her form her family, at which point the two began to live together. H was then forced to work at snack bars and a "soap-land" as a prostitute by X, and most of her salary was taken away by X. It is also said that she had attempted to commit suicide due to the debt she had incurred in her life and the pressure of her pseudo-family.
- In 2001, on X's orders, she married A's eldest son. It's said that she played a role similar to X's treasurer and was the first to confess the disposal location of the three bodies linked to the series of incidents. She kept a diary detailing communal life, in which no incidents of violence or abuse were recorded, but it was noted that the victims' names ceased to appear around the time of their deaths. [clarification needed]
- In the case regarding the theft of the pensions of eldest son and mother of Family C, H was sentenced to two years in prison at the first trial. She was then indicted for murder and other crimes against the eldest and second son of family A and the eldest daughter of family D, and received a sentence of 21 years in prison [citation needed].
- X's Common-Law Husband I 【Arrested】
- Born in 1950.[4]
- He had known X since he was in his twenties [4] and had a long, common-law relationship with her, but it was reportedly a subservient relationship as he claims that she was abusive at times.

- X's Female Cohabitant 【Deceased】
- Born 1941.[4]
- It is said that they got to know each other through her relationship with X's brother.

After hearing about this report, D's husband rushed to the Kobe District Public Prosecutors Office's Amagasaki branch and explained the incident to the police [citation needed].
In August 2012, investigators from the Hyogo Prefectural Police found C hiding out in Amagasaki City under a false name. Based on C's testimony, H and N were re-arrested on charges of theft for withdrawing C and C's mother's pension without permission. During the interrogation of this re-arrest, H confessed to the murder and dumping of the body in September, and N also acknowledged H's confession [citation needed].

Aftermath
On the 12th of December 2012, Miyoko Sumida committed suicide in a holding cell, whilst on suicide watch.
Since October 12, when a series of incidents were uncovered, Sumida had made several statements to her lawyers and police officers in charge of her detention alluding to suicidal ideation, saying things such as, "There is no point in living," "I want to die. How can I die?" The death of the main suspect following arrest made it difficult for investigators to uncover the truth of the case. [citation needed].
On December 19, X's body was cremated in Kobe City but no relatives came to claim the remains [citation needed].
