WWII had been going on in the Pacific for 4 years and in Europe for 2 years before the Japanese bombed Pearl Harbor. This marked the US entry into the war.

Did America have any idea the Japanese were going to attack Pearl Harbor?

The United States Navy Commanders and Roosevelt felt they would attack elsewhere such at the Philippines, Midway or the west coast. Therefore Pearl Harbor had their guard down. The Commanding officer of the Pearl Harbor base and fleet lost his command due to his failure to have the sailors ready for action at all times. Roosevelt was in the middle of negotiations with a Japanese official at the time of the attack. Radio messages and warnings went unheeded so Pearl Harbor was descimated due to failures on the part of communications officers.

Why was the Japanese attack on pearl harbor such a surprise?

The December 7, 1941, attack by the Japanese upon Pearl Harbor was a great surprise for primarily one reason: the Americans expected a Japanese attack to happen much farther west or south in the Pacific region. General hostilities had long been expected, but no one foresaw that the Japanese would dare to venture so far eastwards in order to start a war. The strict secrecy in which the attack was wrapped by the Japanese was yet another key factor.
