Did the Japanese invade US mainland during World War 2?

Answer 1

Actually there was. What most people hear of is of course Peril Harbor and the islands off the coast of Alaska. The Japanese would let hot air balloons off packed with explosives in hope that they would hit major industrial areas/cities. The ones that made the voyage across seas ended up in the Rocky mountains, having no effect on anybody. The Germans never actually attacked but used to shore from subs with American money, I.D., etc....they would just blend in.

Answer 2

No, in fact the only Japanese attack on the "lower 48" to cause any casualties consisted of some small bombs attached to balloons that were sent drifting over the west coast, one of which killed a scoutmaster who was camping in the woods with his wife and his scout troop. He (or one of his troop) found one of the weapons and decided it should be taken to the police, but it exploded when he moved it. The other direct attack was by a Japanese naval Lieutenant in a single-engined plane launched from a submarine. I seem to remember that he dropped incendiary bombs over the remote coastal forests of the northwest, hoping to cause huge conflagrations, but the few small fires he started soon burnt themselves out and even those that were spotted were not regarded as anything but natural. It was only after the war, when Japanese records were examined, that the US authorities even knew about the attack.
