Japan has a conviction rate of over 99%. In several cases, courts have acknowledged confessions were forced and released those imprisoned. To combat this, a law was passed in 2016 requiring some interrogations to be videotaped. However, this only applies to people accused of serious crimes, such as murder, arson and kidnapping, which make up only 3% of cases. In common law countries which practice trial by jury, a high conviction rate may indicate that defendants are not receiving a fair trial. Sometimes Japanese prosecutors decide not to prosecute in the case of minor crimes or when there is a high possibility of innocence.
