Invasion of the Japanese Home Islands

In the early eighties, an okanowan newspaper went around and collected the stories of survivors. Many men dying from what were passed off as injections for the good of your health. The wounded just lay there writhing in agony. This was happening all over the island. And again, maybe that's a little glimpse of the future here, when the japanese home islands are invaded. It may be a better question to ask, although i'm not sure, is, what is an invasion of the home islands going to do to the civilians?
