How is this playing on NHK? The Shimbuns? Anything on KCNA?
I dont think there will ever be anything on KCNA, and they would not even move that fast. As for Japanese TV/Radio (NHK, etc), it is not really a big issue, and would probably be picked up in a few hours, at least for a minor story in the evening news. Japan has a lot of bigger fish to fry right now over and above our migracion problema.
