Overview
- Oiso officials published an external investigation that found the school did not share key bullying information within the staff.
- Investigators logged 33 bullying incidents across the boy’s 1st to 5th grade years, with five classmates linked to 23 cases that included insults, threats, teasing, and smaller lunch portions.
- The report faults staff practices, saying the homeroom teacher withheld a doctor’s diagnosis from administrators and the school failed to record 50 to 60 early departures.
- It also describes a commuting route change that the school first refused by citing police guidance, which police later denied, before the change was approved.
- After the family asked for action, the town labeled the case a serious matter under Japan’s Anti-Bullying Act, and although the report was finished in March 2025 it was not released earlier, drawing sharp criticism from the boy’s guardians.
