Although the following article does not list Education as an apparent reason, I did read once, and it would be common sense that for those who care about their education so much, it has led to suicide. I feel really bad seeing such a high figure, it's way higher than car crashes, and possibly even certain types of illness?

THE number of suicides in Japan exceeded 30,000 in 2009 for a 12th consecutive year, police said today.
A total of 30,181 people killed themselves between January and November, the National Police Agency said, despite government efforts including more counselling services to deter people from taking their own lives.
Japan has one of the world's highest suicide rates, behind only a group of former Soviet bloc countries, says the World Health Organization.
The number of suicides a year in Japan hit the 30,000 mark for the first time in 1998, when the world's second-largest economy was struggling with a number of corporate bankruptcies and soaring jobless rates.
Experts have warned more people may commit suicide as the economy has been hit severely by the global financial crisis
