It isn't a matte of bravery or not. The workers who are the walking dead know that they will die soon maybe a month, two... maybe a year from now...
They may have volunteered.
They may have been asked. If you were asked to do this job, you can not turn it down from cultural standpoint. To refuse, implies you are selfish and self centered and not thinking for the good of all. Your honor is tarnished and so is your family.
My heart goes out to the walking dead. They are doing this to save their loved ones, their neighbor, their way of life. If I lived in Japan and if my expertise was in nuclear power, I would seriously consider volunteering. I don't have kids, Only family I have is my elderly mother, my sister and her three children and I'm already in my 50's. I've had a good life. This is the strength of the Japanese culture.
