There is another exteme called "evaporated people" in Japan, because of the pressures in life they leave their family, friends, identity and disappear. They dont kill themselves, they just take new identities and earn money through cash and hire people so it would hard for those looking for them to track them down.

I work from home as an online tutor and I have mostly Japanese students. If the two faces thing is true, then I feel really touched, because some of my regular students have shared personal stories with me that they probably wouldn't say in real life.
