Reform of the death investigation system in Japan

摘要

The autopsy rate in Japan is lower than that in other countries, and most death investigations have historically been conducted by police officers through external inspection. Although medicolegal autopsy was not performed during the samurai administration, the European death investigation system was adopted in the second half of the 19th century and judicial autopsy began in universities' forensic medicine departments. After World War II, the medical examiner system was introduced under US influence, but it was only adopted in certain areas. Further reforms were introduced in the 21st century-in 2012, two laws relating to death investigation were enacted: The Act on Promotion of Death Investigation (Promotion Act), which provided foundational principles and included measures for investigating the causes of death and identification of bodies, and the Act on the Investigation of Cause of Death and on Identification of Bodies Handled by the Police, which recommended a procedure for death investigation, including a new autopsy system.
