Explanation:

However, there are some debates about the surrender of Japan. You can see them in the description below:

·     Traditionalist School

The traditionalist idea is that the atomic bombs were very important to force Japan to accept surrender and that the bombing prevented a planned invasion of Japan which might have claimed more lives.

·     Revisionist School

The revisionists contend that Japan was ready to give up before the atomic bomb. They say the determination to use bombs still shows ulterior motives on the part of the US government. Japan tried to use the Soviet Union to mediate a peace which was negotiated in 1945.

·     The Soviet Invasion

Japan would have determined the Soviet attack an even bigger shock due to the betrayal underlying it. According to Hasegawa, Japan was also motivated by the desire not to allow the Soviets to participate in the post-war process.

·     Internal Politics

Herbert P. Bix argues that in 1945 several Japanese leaders were in a paranoia state about the possibility of internal rebellion. Particularly, after the government strongly opposed surrender, the emperor, and his cabinet concerned about the consequences of surrender.

·     The Nagasaki Question

The bombing of Nagasaki, hours after the Japanese government discovered Soviet progress, does not receive much attention. Official reports and personal memories from the Japanese government show that Nagasaki had little influence on decision-making.

·     A “Knockout Punch”?

Hasegawa has declared that the Soviet attack did not provide a "knockout punch" that directed to immediate surrender.
