ok we all know that about the attack on Pearl Harbour, but what sort of troop concentrations were on the Islands in Dec 1941? Was invasion even on the Japanese Agenda? And if so could it have worked. Your opinions and knowledge on this would be most welcome.

Your opinions and knowledge on this would be most welcome. It may have been on the agenda for it's advantageous positioning for Japanese expansion and would have laid open the West coast of the United States and the thought that the US would sue for peace. Of the 400 US Aircraft, only 60 survived the attack. The base on Oahu Island was not only the home of the United States Pacific Fleet but about 50,000 American troops. At Pearl Harbor was the largest concentration of U.S. forces in the Pacific. Whether or not the Japanese were going to invade was made irrelevant for the following reasons: In the short run, the Japanese accomplished their objective however they failed in three areas: 1) The aircraft carriers weren't touched. (Enterprise, Hornet & Yorktown) The Japanese thought Yorktown sunk at Coral Sea. Even though they thought they had a 3 to 1 advantage in carriers their escape altered the Japanese plans. 2) The submarines were not attacked. 3) The repair dockyards and fuel-oil storage tanks were undamaged.
I agree with spidge, although the air attacks were successful they were not as successful as they could of been. In my opinion the Japanese could of landed troops in Hawaii whether or not they could of achieved anything is debatable although I suspect not, against 50,000 US troops (majority would of been Green), looking at how the Marines defended Wake Island against overwhealming superiority of the Japanese. The defense of Hawaii would of been similar but with a much greater number of troops on the American's side and a more even weight of forces (probably in favour of the American's). This would of resulted in a costly Japanese victory that would of affected the later land campaigns because of the losses sustained.
I'd have to say that the Japanese could have launched follow on waves that would have been effective in further crippling the US Fleet. An invasion would risk retaliation by the US carriers and could have devastated the Japanese success.
Some great photos here of Pearl Harbor 1941 and during the attack. This site extends onto the Doolittle raid. http://www.freerepublic.com/focus/f-news/1296093/posts
Great info guys. I have read the defense of wake Island and seeing what happened there my own view is that it would have been impractical to invade Hawaii, especially given the numbers of troops that were on the island. The Japanese missed a great opportunity on Dec 7th because they didnt cripple the Carriers and the Docks facility on Pearl. It was a mistake they would pay for handsomely
The Japanese Navy studied invading Hawaii and decided that they simply did not have the merchant ship capacity to supply an invading and occupation force, as well as the captive population. However, that view might have changed had they won the Battle of Midway and erased the American Navy from the equation.

I think an invasion may have been in the original plans. Take into consideration that the fuel dumps were left intact. You would think that this would have been an essential target to be destroyed. Peharps the missing American carriers altered the plans. Having all of that air power available to the US defence might have made them think twice about the invasion of Pearl.
An interesting read is "The Great Pacific War" ( ca 1927 ) by a Briton named Hector C Bywater, telling of a theorectical war during 1931-1933 between Japan and the US. The book charted out the Japanese invasion of Manila, the attack on Pearl Harbor, occupation of Guam. It foretold the supremacy of the US industrial might, the island-hopping by US Marine and Naval forces, aand the invasion of the Japanese Home Islands to end the war. Bywater died under mysterious circumstances in 1940 - did Japan have him killed to keep him quiet as he was an expert on Japan's military ?

Pearl Harbor Inset: IN THE WAKE OF THE PROPHET, by Frank Pierce Young# "Hector C. Bywater died in bed, at home in London, alone, sometime between August 16 and 17 of 1940. He was declared a victim of acute alcoholism, physicians bypassed anything else, and his body swiftly cremated. Modern investigation suggests he may well have been murdered, using poison."
Thanks for that info R Leonard! Really good breakdown of the US strength In addition to R. Leonard's listing of Army forces, and the well-known naval strength at Pearl, Oahu also hosted the Marine Corps Air Station at Ewa and the Naval Air Station at Kaneohe Bay, both of which were attacked on Dec. 7th.
