Former lecturer Yotsuya Otsuka, who “voyeurized his students’, admits to posting children’s names on SNS. Takato Mori (25) repeatedly secretly filmed the underwear of 12 of his female students at a school building in Tokyo between March and August last year using his smartphone.

Prosecutors charged the former instructor with violating the Personal Information Protection Act, alleging that he had posted the names and addresses of six children attending the cram school in a group chat on social media.
