Actually, the US killed far more. The Soviets only killed around 21,400 Japanese, in the Battle of Okinawa alone the US killed around 70,000 Japanese troops. Japanese historians frequently lie and revise WW2 history, as can be seen in their denial of the existence of Comfort Women, and the repeated attempts to revise Japanese history books. Little credence can be give to what Japanese historians said. Hasegawa's claims are flatly refuted by the very explanations given by the Emperor himself when announcing the Japanese surrender. The words of the Emperor, at the time of the Japanese surrender, carry far, far, far, far more weight than what a historian said many decades later, especially from a country that is known for revising its history and refuting well known facts.I should be noted that the Red army destroyed more Japanese forces (meaning killed more Japanese soldiers) during Manchurian Operation than the USA had done for the whole war. The most Japanese soldiers were killed by Chinese by the way. Japanese historian Tsuyoshi Hasegawa - Wikipedia claims that the Pacific war ended not due to nuclear bombings, but because to the entry of the Soviets. Also the fate of the last Russian monarch and his family at the hands of reds and prospects for a punitive red occupation influenced the surrender. Neither Soviets defeated Germans alone nor USA did the same with Japanese. The Allies defeated Japan and Germany.
Here is the Emperor's surrender speech:
Note in the bold and highlighted portion that the Emperor specifically makes mention of the atomic bom, and gives it as a reason for surrender. The emperor said Japan was surrendering not only to save Japan, but prevent the total extinction of civilization as well. Japanese historians like Hasegawa can lie all they want, just like they lie about the existence of Comfort Women, but we don't have and shouldn't repeat their lies or give them any credence. The speech, made at the time of the surrender, not many decades, SHOWS THE ATOMIC BOMB WAS THE REASON FOR THE SURRENDER.After pondering deeply the general trends of the world and the actual conditions obtaining in Our Empire today, We have decided to effect a settlement of the present situation by resorting to an extraordinary measure.
We have ordered Our Government to communicate to the Governments of the United States, Great Britain, China and the Soviet Union that Our Empire accepts the provisions of their Joint Declaration.
To strive for the common prosperity and happiness of all nations as well as the security and well-being of Our subjects is the solemn obligation which has been handed down by Our Imperial Ancestors, and which We lay close to heart. Indeed, We declared war on America and Britain out of Our sincere desire to secure Japan's self-preservation and the stabilization of East Asia, it being far from Our thought either to infringe upon the sovereignty of other nations or to embark upon territorial aggrandisement. But now the war has lasted for nearly four years. Despite the best that has been done by every one -- the gallant fighting of military and naval forces, the diligence and assiduity of Our servants of the State and the devoted service of Our one hundred million people, the war situation has developed not necessarily to Japan's advantage, while the general trends of the world have all turned against her interest. Moreover, the enemy has begun to employ a new and most cruel bomb, the power of which to do damage is indeed incalculable, taking the toll of many innocent lives. Should we continue to fight, it would not only result in an ultimate collapse and obliteration of the Japanese nation, but also it would lead to the total extinction of human civilization. Such being the case, how are We to save the millions of Our subjects; or to atone Ourselves before the hallowed spirits of Our Imperial Ancestors? This is the reason why We have ordered the acceptance of the provisions of the Joint Declaration of the Powers.

Japanese civilians were throwing themselves off cliffs at Okinawa rather than surrender, and 90% of the Japanese troops at Okinawa died before surrender. at Okinawa! Given the US experience at Okinawa, there is no reason to assume that the Japanese would behave in a rational manner, and not commit suicide as a nation rather than surrender the sacred lands of the Japanese.Japan was indeed undoubtedly on its last legs by 1945, and a sizeable coalition of politicians and industrialists in Tokyo recognised that.
However, in the absence of creative U.S. diplomacy that might have exploited the situation, something was needed to override the obstinacy of the militarist die-hards (in large part by persuading the Emperor to openly force the issue). The evidence seems persuasive to me that it was fear of the Russians that provided that tip of the scales.
And given the Japanese actions in Pearl Harbor, where the Japanese were engaging peace negotiations while its fleet was sailing to launch a sneak attack on the US, there was absolutely no reason for the US to trust the Japanese in anything other than an unconditional surrender. The Japanese could have at least tried to offer to the US some terms if the Japanese were sincere about surrendering, but they did not, because the Japanese were not considering surrendering. Before the atomic bombings, the Japanese were looking at some kind of truce or negotiated settlement where they would not have to surrender.
