This is a continuation from our previous post about the Khabarovsk War Crimes Trial, which unearths Unit 731. If you are not familiar with Unit 731, check here. 
Key points in this post: 
1. The Axis of Power's aggression toward the Soviet Union which led to the Khabarovsk War Crimes Trial.
2. Comparing Unit 100 and Unit 731.

​The Japan Empire attacked the Soviet Union during the Pacific Asia War. According to the Japanese militarists' strategical plans for aggression, "the USSR. was usually referred to as 'Target No. 1.'"

Here is the timeline of the Japanese Empire's aggression toward the USSR from the Khabarovsk Trial. 

​And after the war, the Nuremberg Trial (International Military Tribunal) and the Tokyo War Crimes Trial (International Military Tribunal of the Far East) attempted to bring war criminals to justice. However, unlike the International Military Tribunal, the International Military Tribunal of the Far East wasn't created by an international agreement. It was made clear during the tribunal that the Imperial Japanese Army was exerting aggression toward the Soviet Union. 

In the preliminary research for the Khabarovsk Trial, it was established that during the aggression and preparing for the aggression toward the Soviet Union and other countries, the Japanese Empire had "employ, a criminal means of mass extermination of human beings—the weapon of bacteriological warfare. "
Further, during the preliminary investigation, it was clear that the Japanese General Staff and Ministry for War set up a bacteriological laboratory with Ishii Shiro as its leader after the seizure of Manchuria. Ishii Shiro then became a Lieutenant General in the Army Medical Service. He had always been seen in Japan as "an ideologist of bacteriological warfare." 

Kawashima Kiyoshi, a defendant in the trial, was formerly Major General in the Japanese Army Medical Service confirmed that Emperor Hirohito was the one providing the secret instructions. Furthermore, he confirmed that the Japanese General Staff and Ministry for War was formed the two top-secret units for preparing and conducting bacteriological warfare in Manchuria as early as 1935-1936. 
The two top-secret units were Unit 731 and Unit 100. Both had a lot in similarities, i.e., human experimentation, and they both had branches throughout the world. Here is a table to make the identification of the two units easier:
