Racial and Ideological hatred, towards Slavs, Jews and Communists. The war was portrayed as a war to squash "Judeo-Bolshevism" and therefore avenge the lost of WW1 (Stab-in-the-back myth). The native peoples of the Soviet Union were also to be used as slaves for German settlers and eventually genocided for "Lebenstraum" (open living space) according to Generalplan Ost. For an example of what this would look like, please refer to the United States of America.
Aquire the huge amount of resources held by the Soviet Union, especially oil and food. Most people know the Nazis had heavy fuel shortages but they were dependent on Ukrainian grain imports to feed their population. Part of the reason Operation Barbarossa (the invasion of USSR) had to be done quickly is that they had to capture the Ukrainian grain harvest to feed Germany that year.
Additionally the Nazis also severally underestimated the strength and determination of the Soviet military and people. They believed with a sudden overwhelming strike they could destroy all Soviet resistance at the border and finish the war in a few months. Thanks to the glorious heroic sacrifices made by the Red Army, the tenacity and resistance of Soviet people and the leadership of Stalin and the Communist Party, the Soviet Union turned the tables and routed the fascist invaders, saving the world from Nazism in the process.

The Japanese got their asses handed to them so hardat the Battle of Khalkhin Gol by Georgy "Big Dick" Zhukov that the Japanese decided to never mess with the Soviet Union again. They were busy with invading China and fighting Mao "Huge Cock" Zedong's guerillas as well, and invading Siberia would be far too difficult for nearly no gains.
