During ww2 the us were working on an atomic bomb which was intentionally going to be used on germany, but instead used on japan this was because germany surrendered before development was finished on the bomb.
The primary factor that determined when the first atomic bombs were ready for use was when the serious program of their production started if the americans had been convinced in 1940, rather than 1941, that an atomic bomb was worth seriously pursuing, then the gadget might have been ready by july 1944, not july 1945. So the reason why bombs were used on japan and not germany is that germany, who the bomb was meant for was defeated and bombing germany now would serve no purpose and that an invasion of japan would drag out the war and take the lives of millions.

The story of the atomic bomb started around the turn of the century when a small number of physicists began to think about, discuss, and publish papers about the phenomenon of radioactivity, the behavior of alpha particles, and the properties of various materials when irradiated. The second atomic weapon used against japan, this single bomb resulted in the deaths of 80,000 japanese citizens for truman, the choice whether or not to use the atomic bomb was the most difficult decision of his life.
