So I'm in the pre planning stages of a comic idea with various historical settings and I wanna tell a story about Unit 731 (The Japanese chemical and biological weapon experimentation facility from WWII) and I need to know what happened to the scientists who worked there and some of the more horrifying experiments conducted there. Can you help me?
I went to their base in Harbin about a year ago, which is now a museum.
Some of their experiments included live vivisections, infecting people with deadly diseases like ebola, cutting people's limbs off and sewing them back on, and tying people naked outside in winter (Harbin gets as cold as -40 celsius, though generally it's "only" about -25). As for the scientists, I was told that they were mostly let off in return for handing over all their notes to America, and I saw some copies of the various notes they gave in; things like how the diseases they infected spread, symptom development, etc.
(I went with a Japanese history graduate, and he confirmed that the museum was telling the truth; Chinese anti-Japanese museums can be rather sensationalist, but he said that all the stuff there was accurate.)
We also saw the furnaces outside the museum, where they used to burn all the corpses of people who'd died in their experiments.
