In a disturbing case involving a male teacher at a public high school in Osaka, the Osaka Prefectural Board of Education has faced criticism for its significant delay in responding to allegations of obscene acts against a female student. The allegations were reported to the board in August 2020; however, it was not until 2025 that the board received a second report prompting an investigation. During the interim period, the board failed to take any proactive measures regarding the initial report, which has raised questions about the accountability and procedures involved in addressing misconduct in educational institutions.

According to the results announced by the Osaka Audit Committee, the male teacher had engaged in obscene behavior while employed at a municipal high school, after which he was later hired by the prefectural education board and continued working in a public high school. Alarmingly, it has been revealed that the inappropriate conduct persisted even after the victim reached adulthood. The board's eventual investigation in 2025 determined that the actions embarked upon while he was at the city high school could not be subjected to disciplinary action due to the elapsed time, and those occurring after the victim became an adult did not warrant punishment. Consequently, the teacher was dismissed on grounds of severe misconduct, losing his teaching license.

The audit committee has underscored that the teacher's actions undoubtedly warrant disciplinary action, indicating that the board needs to reevaluate its decision-making procedures and response times concerning such cases. Officials from the board’s personnel department have expressed a commitment to reviewing how the situation was handled following the 2020 report, indicating a growing recognition of the need for improvement in response protocols and accountability when it comes to allegations of misconduct among educational staff.
