This also very nearly led us to war with the Soviet Union and USA. Stalin was so infuriated with MacArther keeping the medical research and protecting the Japanese doctors Stalin nearly declared war over it. Many Red Army POWs were experimented on and Stalin wanted the Japanese held accountable. Who could blame him? I was never able to find out who or how war was avoided. Probably classified. My theory is he was given US nuclear secrets because Europe was already sliced and diced after VE day.
Seeing as how the USSR declared war on Japan between the atomic bombings of Hiroshima and Nagasaki, just days before the capitulation of Japan, how did Japan ever manage to collect a significant number of Soviet POWs?
