The Emperor only changed its mind after the first atomic bomb drop on Hiroshima. The Big Six did not accept the American terns (Big Six wanted no invasion, wanted Japan to try its own war criminals, and wanted the Emperor to lead the country and answer to no-one). The Emperor gad to tell the council of Big Six that he already made up his mind to accept unconditional surrender and that he was going to tell Japan the very next day. Some military officers stormed the place trying to steal the radio recording of the Emperor. Army Minister Anami committed suicide because he could not bear to hear the radio address [2]
Japan military was geared to fight to the end on the main islands and dropping the atomic bombs was necessary to stop them. Dropping the bombs saved American lives, and maybe even some Japanese ones.

Wrong. Hiroshima and Nagasaki killed way more people than the Tokyo firebombing 250.000 and 110.000 vs 80.000), and needed only a single bomb on a single plane, compared to the massive efforts to destroy Tokyo.
Snark aside, your total may be including victims of radiation that died months and years later. If so, these victims were not incorporated in the decision made by the Emperor 2 days later - because these deaths did not happen yet and were not foretold/expected. (And you should also adjust your posting).
Radiation deaths after the bombing were neglectable though. 3000 more cancer deaths, leukemia.
But it should be clear that, while Truman delegated authority for picking up targets and dropping the bomb to military and State department, Truman along with the rest of his administration Sec of State Byrnes, Sec of War Stimson, Chief of Staff Gen. Marshall already decided the atomic bomb will be dropped on Japan. When Sec of State Byrnes explicitly warned the Japanese about "prompt and utter destruction" he meant exactly that. [0]
Dropping the bomb was done with Truman's approval.
