Shukan Shincho weekly has reported that a representative of Crown Prince Naruhito's household contacted the elite Gakushuin Primary School and recommended that medicine to treat attention deficit hyperactivity disorder was added to meals.
Princess Aiko, 8, was left traumatised by an encounter with a group of misbehaving boys back in March.
The agency says she was only able to attend the first hour of classes between March 8 and 11 after being shocked at the "rough behaviour" of boys in her grade.
She failed to attend the end-of-year graduation ceremony later that month and missed the April 9 welcoming ceremony for new third grade students. Since then, Princess Aiko has attended school for three hours a day, accompanied by her mother.
