This one sparked the West Coast invasion scare. Where was the first Japanese attack on the mainland United States?

Even the mainland U.S. wasn't safe from attack in WWII. A Japanese submarine targeted a U.S. coastal oil well and storage facility near Santa Barbara, something that became known as "the Bombardment of Ellwood". Minimal damage occurred...except to the American psyche.
