In August 2021, in Adachi, Tokyo, a wife named Takita allegedly hired a hitman through social media to murder her husband due to financial debts exceeding 10 million yen and deteriorating marital relations. The husband was attacked while sleeping, stabbed in the chest, and seriously injured but survived. The hitman, Konishi Kota, and accomplices were arrested, and Takita was later arrested and tried for attempted murder. She denied the charges, claiming she sought help against loan shark harassment, but evidence including social media messages and search history indicated premeditated murder planning. Takita was sentenced to 10 years in prison and appealed the verdict. The case revealed the existence of revenge-for-hire services on social media and raised concerns about crime facilitated by such platforms.

Attempted murder in Tokyo involving a wife hiring a hitman via SNS
Domestic Violence
The case involves a marital conflict exacerbated by financial debts and strict financial control by the husband, leading to the wife's resentment and alleged request for murder. The use of social media to hire hitmen and the involvement of acquaintances in the attack illustrate escalation and premeditation in domestic violence. False accusations and manipulation were used to justify the crime, highlighting coercive control and emotional abuse dynamics.
Police investigation included analysis of security footage, smartphone data, and social media communications. Arrests were made of the attackers and the wife after evidence linked her to the crime. The credibility of the main offender's testimony was key in prosecution. The wife denied charges and appealed the conviction. The case exposed the existence of revenge-for-hire services on social media.
Initial investigation treated the incident as robbery. The wife's involvement was unknown until smartphone analysis. The wife claimed her contact with revenge-for-hire was for debt harassment, not murder, creating conflicting narratives. The defense suggested misunderstanding, but evidence and testimony contradicted this.
The wife, burdened by gambling debts hidden from her husband, faced financial restrictions imposed by him. She searched online for murder methods and revenge-for-hire services, contacting one via Twitter and Telegram. She requested the murder of her husband, providing detailed information about the house. Konishi Kota accepted the request, involving his friend Sakai Ryota and a lookout. They attacked the husband while he slept, stabbing him near the heart. The husband resisted, and the attackers fled. Police arrested the perpetrators and later the wife after linking her via smartphone evidence. The wife denied the murder request, but the court accepted the offender's testimony and evidence, sentencing her to 10 years.
High risk due to financial strain, domestic conflict, premeditation, and use of third parties to carry out violence. The involvement of social media platforms increases accessibility to criminal facilitation.
Financial control and debt can escalate domestic conflicts to violence. Social media facilitates criminal arrangements like revenge-for-hire, increasing risk. Premeditation and manipulation, including false accusations, are critical warning signs. Evidence from digital communications is vital in modern investigations. Early intervention in financial and marital disputes may prevent escalation.
The wife's extensive online searches for murder methods and revenge-for-hire services, and the husband's discovery of large debts leading to financial restrictions.
Social media messages between the wife and hitman, smartphone data linking communications, security camera footage of attackers, and testimonies of the offenders.
Digital evidence from smartphones and social media, security camera footage, and offender testimonies were strongest.
Not reported.
The wife's involvement was unknown initially and revealed after smartphone analysis. The wife's denial persisted through trial and appeal, but offender testimony and evidence confirmed her role.
Exact motives beyond financial and familial dissatisfaction remain partially unclear due to conflicting claims by the wife.
