As with almost everything there are countless reasons why Japan didn't surrender earlier. [1] By June of 1945 Japan's leaders did want out of the war, but were still hoping for a surrender that allowed them to keep much of their holdings (I think people often forget how much of East Asia Japan had solidly controlled for almost 10 years at this point). And they were being strung along by the Soviet union who was supposed to mediate peace, yet had their own motives to prolong the war until they could join. And even after dropping 2 nukes, and believing the US had 100 more, it took days more, and some additional attacks, to convince Japan to surrender. And even after all this, there was a serious attempted coup.
