Japanese's bad habit.

I often hear many families who lives in Fukushima can't evacuate. Why don't they evacuate from Fukushima ? Some say neighbors blame those who are going to do evacuating. Japanese blame a person who derange their harmony. I know that harmony of relationship with their neighborhood is important. However this is something life-thretening to their children. Mind your own business. Why they don't make mention of an individual person. They should allow in their beliefs that they have an obligation to protect their children.
