In November 1988, 17-year-old Junko Furuta, a high school student in Misato, Saitama, Japan, was abducted by a group of teenage boys led by Hiroshi Miyano, a youth with yakuza connections. She was held captive for roughly 40 days in a house in the Adachi ward of Tokyo in the home of one of her captors, whose own parents were living in the same building and reportedly did not intervene. During her captivity, Junko was subjected to relentless and brutal abuse by four primary perpetrators and others who came and went. She died in January 1989 from her injuries. Her body was concealed in a concrete-filled drum and abandoned, which gave the crime its common name in Japan: the "concrete-encased high school girl murder case."

The legal fallout drew lasting outrage. Because all four main offenders were minors under Japanese law, their identities were initially protected and they were shielded by the juvenile justice system, which prioritized rehabilitation over punishment. The sentences struck many as shockingly lenient given the severity of the crime. Ringleader Hiroshi Miyano received the harshest term at around 20 years, while the others received far shorter sentences... roughly five to ten years, five to nine years, and five to seven years respectively. Prosecutors and the public viewed the outcomes as wholly inadequate, and all four were eventually released back into society.

The aftermath deepened public anger. At least one offender reoffended, including a conviction tied to a violent attack years after his release. Some married and built ordinary lives, reportedly disclosing their pasts to their spouses; one died in 2021 after years of illness and isolation. The case became a touchstone in Japanese debates over juvenile sentencing, victims' rights, and whether protections afforded to young offenders can fail to deliver justice for catastrophic crimes. Decades later, Junko Furuta's name remains a symbol of those unresolved tensions, and her case is still cited whenever Japan revisits how it treats minors who commit grave offenses.
