Elementary school teacher Fumiya Kosemura pleaded guilty to charges of sharing child pornography via social media, in the first hearing on his case at the Nagoya District Court on Wednesday. The charges are "correct, and I'm very sorry," said Kosemura, 37, a teacher at a public elementary school in Yokohama, who has been indicted for voyeurism and indecent assault. Public prosecutors said Kosemura became acquainted with Yuji Moriyama, 42, a teacher at a public elementary school in Nagoya, who started engaging in voyeurism about a decade ago through social media communications with people who have the same sexual preference. Moriyama invited the defendant and others to a messaging app in August 2024, and they started posting video footage to their group chat, the prosecutors said. Kosemura and Moriyama are among six teachers arrested in a recent series of child pornography crimes in the country.
