The grim spike in the statistics is linked to the typical start date of the new school term after the summer holiday has ended.
"The long break from school enables you to stay at home, so it's heaven for those who are bullied," Nanae said. "When summer ends, you have to go back. And once you start worrying about getting bullied, committing suicide might be possible."..
Nanae thinks the Japanese education system's focus on collective thinking is at the root cause of the problem.
"In Japan, you have to fall in line with other people. And if you cannot do that, you're either ignored or bullied," she said. "You are required to have a unified opinion, and it crushes the uniqueness every person has. But that uniqueness is not something to destroy."
Some experts agree. Child psychiatrist Dr. Ken Takaoka said the suicide rate increases when school restarts because schools "prioritize collective (action). Children who do not get along in a group will suffer."'
