A former elementary school teacher in Nagoya, Japan, has been sentenced to two and a half years in prison for his role in creating and operating a social media group used to share secretly recorded images of female children. The Nagoya District Court condemned the act as "cowardly," noting that the group created a dangerous situation in which it was unknown how the images might be further misused. The case involved multiple teachers who allegedly captured and circulated the illicit material within the private online group.
