Victims’ Participation Rights In Japanese Criminal Procedure
1. Legal Framework
Victims’ rights in Japan have gradually expanded. The key provisions include:

Historically, victims had limited procedural participation.
Reforms in 2005–2012 introduced Saiban-in trials (lay judge system) and enhanced victims’ roles.
(B) Victim Participation Rights
Right to be heard (Article 315–1 CCP)
Victims can express opinions on sentencing and protection measures.
Right to claim damages in criminal court
Victims may file civil claims in criminal trials.
Right to attend hearings
Especially in serious crimes under lay judge trials.
Right to request information
Prosecutors provide updates on investigation and trial progress.
(C) Key Reforms
2005 Amendment: Introduced participation in criminal proceedings, especially for serious crimes like murder, sexual assault.
Victim Liaison Offices: Support victims to exercise rights.
