After the war, twelve Unit 731 members were tried by the USSR in the 1949 Khabarovsk war crimes trials and sentenced to prison. However, many key figures, including Ishii, were granted immunity by the United States in exchange for their research data.

The USSR likely also handed out relatively lenient sentences at the Khabarovsk trials in exchange for information and used Japanese documentation to build its Biological Weapons facility in Sverdlovsk
