Nonprofit organizations and other entities supporting children are stepping up efforts to prevent kids from committing suicide as students who kill themselves tend to do so around the end of the summer school vacation.

According to figures released by the Cabinet Office in 2015, suicides among people aged 18 or younger between 1972 and 2013 were mostly concentrated on or around Sept. 1, when the new semester starts at schools in many parts of the country.

The children's suicide rate also tends to rise around the end of the spring and Golden Week school holidays in April and May, suggesting that returning to school after vacation is a huge hurdle for children, especially among those who are worried about being bullied.
