On April 1st 2022 the legal age of adulthood in Japan was lowered from 20 years to 18 years. As a result, the revised Juvenile Act makes more crimes committed by 18- and 19-year-olds applicable to criminal trials. However, this is not the only change in the criminal law system impacted by the lowered legal age of adulthood (Baseel, 2021).
Besides this, the changes in the Juvenile Act qualify 18- and 19-year-olds to act as lay judges in criminal trials. High School students expressed concerns about the new opportunity. Most often students criticize their little experience and inability to decide about life and death. Students see this decision as irresponsible. On the other hand, others view the opportunity positively, as this could be a possibility for young people to voice their opinions about ongoing trials (The Mainichi, 2022).
Overall, the participation of young people in Japan's law judge system has been lacking since the introduction of the lay judge system in 2009. In 2020, only 1.2 percent of law judges were students, and only 14 percent were in their 20s. Courts hope that the changes in the Juvenile Act will increase youth participation as lay judges. From January 2023 onwards 18- and 19-year-olds will be able to take part in trials as lay judges. Nevertheless, being a student is considered a valid reason to refuse to participate (The Mainichi, 2022).
