How come that the Japanese didn’t invade Hawaii?
The distance between mainland Japan and Hawaii is around 6,600 kilometers, which is further than the distance between New York and Paris. In the attack on Pearl Harbor in 1941, Japan aimed to attack American forces by surprise in order to reduce the number of Japanese casualties along with ensuring that the American forces were entirely unprepared. If Japan had chosen to invade the island they would have lost this advantage of surprise and would have likely been severely beaten back by the American forces. In all, Japan did not invade Hawaii due to the extreme distance between the islands and Japanese held territory along with the difficulty they would face in trying to take the island.
