Could the Japanese have invaded the US?

[PanzerGeneral]

In order to see if possible a small Janapnese force could occupy west coast cities and ports for short time. Ok anyone have info on how many infantry and armoured divisions the US Army and Army Air Force and type of air units had and how many Marine Divisions we had and reserve and National Guard Units we had and locations around the world on 12/07/1941? Also, what was the population of California , Oregon, and Washington and major cities in those states include Vancouver Canada and Candadian/U.K. forces including naval there and location bases of our naval Units. Including how many Army, Marine, Navy and Naval Air units down to smallest size unit, Army Air force and types units were on west Coast of Panama canal? As I recall just to defend LA from air raids all our flak units had to moved to LA after 12/07/1941. What forces land sea and air did the Japanese have available to deploy in Pacific?
