A 16-year-old girl detained by Hyogo police on assault charges died from severe malnutrition five months after her release. Her family filed a lawsuit on June 17 seeking 190 million yen in damages from Japan’s government and Hyogo Prefecture, claiming illegal arrest and coercive interrogation caused the eating disorder that led to her death. The case has revived criticism of Japan’s detention system, known as “hostage justice.”

What Happened During the Detention

The girl worked at a disability care facility in Hyogo. In February 2025, she held the jaw of a participant who tried to bite others during an event. A witness later reported the incident as abuse to local authorities. Police arrested her on June 17, 2025, and held her for 18 days. She denied the charges throughout interrogation but was pressured to confess, according to court filings. She was released on July 4 and declared not guilty on July 4.

Health Decline and Death

After her release, the girl developed an eating disorder and could not eat. She died on December 14, 2025, from extreme malnutrition. Her weight had fallen to approximately 20 kilograms by early December. Her family claims the illegal detention and harsh interrogation caused the eating disorder that led to her death. Former Justice Minister Mori Masako said on June 18 she was “deeply regretful” the girl’s life could not be saved.

The Lawsuit and Government Response

The family filed suit at Kobe District Court on June 17, seeking 190 million yen in damages from the national government and Hyogo Prefecture. The mother said: “I want to know what happened to my daughter. I want her to be apologized to.” Both Hyogo police and the Kobe District Prosecutor’s Office declined to comment, stating they had not yet received the lawsuit.

Broader Debate on Japan’s Detention System

The case has intensified scrutiny of Japan’s detention practices, where suspects can be held for up to 23 days without charge. Critics call this system “hostage justice” because prolonged detention pressures suspects to confess, even when innocent. The case emerged during parliamentary debate on criminal procedure reforms aimed at addressing these concerns.
