Japan attacked pearl harbor because of the following:
1. They need to increase their resources in preparation to their expansion in the Asia Pacific.
2. Restrictions. United States is also interested in the Asia Pacific region. They placed economic restrictions to Japan inhibiting Japanese business growth.
3. Expansion. The president of the United States bring the US Pacifc fleet to the Pearl Harbor. This is to give threat to Japan. Japan knoes that war is inevitable their move is to attacked first.

This attacked took 2500 lives of Americans, 18 ships, 300 planes but Japan did not able to exoand in the Pacific and acquisition of resouces did not happen.

Japan attacked Pearl Harbor in retaliation against the United States for cutting off Japan's oil supplies. 


The conflicts that became "World War II" began in the 1930s with Japanese imperial aggression into Manchuria, to take over Chinese territory.  Beginning in 1938, the United States adopted increasingly severe trade restrictions against Japan in response.  When Japan moved into French Indochina in 1941, the USA froze all Japanese financial assets in the USA and placed an embargo on all oil and gasoline shipments to Japan.  The Japanese viewed the embargo as an act of war, and their attack against the US at Pearl Harbor was (from their viewpoint) a response to US trade sanctions against them.
