Was japan aware in any way that the United States was gonna drop an Atomic Bomb?

Question:

For my history class we have a court case to whether harry truman is innocent or not for the blood shed and id like to know if japan was aware in any way of the Atomic Bomb

Answer:

No, Japan was not aware of that
By the end of July, 1945, Japan was ready to surrender by accepting the Potsdam Declaration: .http://en.wikipedia.org/wiki/Potsdam_Dec…
As you can see, the Allied Powers forced Japan to accept "Unconditional Surrender," but Japanese government desperately requested one condition: "Save the life of the Emperor." The Final talks took place between Tokyo and Washington (through telegrams, I believe): however, the Allied Powers did not accept Japanese request, which delayed Japan's surrender.

Then, atomic bombs were dropped on Hiroshima (August 6th) and Nagasaki (August 9th). By the end of July 1945, almost all the cities in Japan had been destroyed by the carpet bombings by US Air Force, which killed approx 800,000 Japanese civilians prior to the atomic bombings on Hiroshima and Nagasaki.

The "Tokyo Air Raid" on March 10, 1945 alone killed 100,000 civilians. So, the civilians in Japan were deadly scared of US carpet bombings on their cities, but, they knew nothing about atomic bombs.

BTW, the US did not know how deadly the atomic bombs were either. So, they needed to make sure the power of their two nuclear bombs (uranium bomb on Hiroshima and plutonium bomb on Nagasaki). They didn't care how many "Japs" would be killed. As a result, 140,000 and 80,000 civilians (not military personnel) were slaughtered in Hiroshima and Nagasaki on the spot (a large number of other victims were died of nuclear radiation-related diseases afterwords).

The Japanese government might have been aware of US development of nuclear weapons and their experimental detonations in the desert of Nevada, but Japanese civilians were not informed any of their new bombs until the last moment.

Edit:
If you want to know USF carpet bombings all over japan in 1945, please take a look at this.
