They didn't. By the time the USSR finished fighting Germany (by themselves because Churchill and FDR didn't want to help), the US had been fighting Japan for a while. The USSR did declare war on Japan after the Germans surrendered. Before the USSR could do anything, the US dropped it's two atomic bombs. The Japanese were rumored to have started peace negotiations with the USSR agreeing to act as the liason after the Little Boy bombing, but the Fat Man prevented it. Many say the US bombed Japan because they didn't want the USSR sweeping in as the hero.
The US helped Japan turn from an agrarian society to that of an industrial nation which relied upon it's industries to help the Japanese economy recover from the devastating effects of war (US bombings) .

Japan was trying to develop weapons which could reach the US. balloon carrying fire bombs did reach the US but those didn't do much. The real deal was that Germany was trying to develop an atomic bomb but the US beat them. We don't have proof that Japan were trying to develop one. August 6 and 9 1945, Japan suffered the pain of the nuclear bombs.
