The company that makes browning firearms I believe is in the southern part of the country, far from the worst of the disaster, the rest of the companies I do not know. I would not be surprised however, that they will be affected by fuel and power shortages for a while, and if this nuclear mess gets much worse, then who knows what will happen. As far as japanese auto makers, a huge amount of their cars are made here now. Honda has a plant NW of Columbus, Oh, for example. They do have some parts that come from Japan, and some of the smaller japanese car makes still are built there.
