Question

Why did Japanese Americans face more restrictions than Italian or German Americans during WW2?

Answer 1

In fact, Japanese Americans and other Asian Americans had long been characterized as a foreign "Yellow Peril" that was a threat to the United States. Prejudice against Japanese Americans, including laws preventing them from owning land, existed long before World War II. Even though Japanese Americans largely considered themselves loyal and even patriotic Americans, suspicions about their loyalties were pervasive. Before Pearl Harbor was bombed, President Roosevelt secretly commissioned Curtis Munson, a businessman, to assess the possibility that Japanese Americans would pose a threat to US security. Munson’s report found that "There will be no armed uprising of Japanese" in the United States. "For the most part," the report says, "the local Japanese are loyal to the United States or, at worst, hope that by remaining quiet they can avoid concentration camps or irresponsible mobs."
