At a junior high school in Shinagawa Ward, Tokyo, despite bullying that corresponds to a "serious situation" stipulated by law, the certification was delayed by two years. Students who attended junior high schools in the ward were bullied for eight months from February of the first year of the year Reiwa such as notes such as "shine" and "kiero" were placed on bald boxes on their desks.
After receiving a complaint from parents, it was certified two years later in May last year.
