Is this really true. AFAIK arab country has the most many suicide incident if suicide bombing will be counted. Hahaha. But seriously most of the people of japan has a unique behaviour which is they are full pride. Once they become a failure, they choose to suicide rather than to become a disgrace to his/her own family.
This is probably a legacy of the past? This behavior occurs since the existence of suicide bombers. It is a pity of course. Such a unique country and such foolish customs.
