This youtube video suggests that if Operation Downfall went ahead then Japan would start increasing it's use of bioweopons to such a level that a plague would spread across the world and lead to the downfall of the superpowers such as the Soviet Union, America, and Britain. Would this be the case? And if so how would the world look after the plague subsided, perhaps a cure is developed or perhaps the plague just dies out for some reason. How the world rebuild? Would Britain try and take back lost colonies, thanks to the plague, like India? Would America and the Soviet Union still be on top? How would their relationship be? Would the plague signify the end of the Soviet Union so by the time the plague subsided the Soviet Union would already down? How would the world look like going into the twenty first century? Would places where the plague would not hit the hardest like South America and Africa be the new superpowers? Places like Brazil or South Africa for example? What you think?

 
This is borderline ASB. Japan did a lot research, but never developed anywhere close to what you’re suggesting.
Even before Downfall was scheduled to start Japan had lost its ability to carry out such acts on a significant scale.

Agreed, they might be able to hit the invasion force with chemicals but not much more than that...
 
Not likely. There is very little info on the efforts done by the Japanese to select their bacterial strains, but if as indicated they are selected for rapid lethality, they would not be too difficult to contain. So maybe sporadic deaths, but no pandemic
 
I wouldn't take Monsieur Z's videos too seriously, they can be entertaining but they're implausible at the best of times and at their worst...you have Operation Downfall sending the world back into the dark ages.
 
Japan used its biological weapons against china during the war. a starved and weakened population in a state of near anarchy with almost zero access to even basic healthcare,aka literally the absolute best case scenario for this kind of weapons. it killed people,but not much more than standard warfare and quickly petered out. against the usa,even if we assume it somehow reached it,it would cause a very few deaths and thats it.

I have a kid who is an epidemiologist and lives this world to a degree. She has also coordinated with Homeland sec on Bio terrorism, as concerns vaccination plans, etc.
The spreading of bio warfare is not easy and in fact almost impossible. The right conditions (sanitation, vector, resistance) all come into play. Virus are constantly morphing and becoming more and less dangerous on a daily basis. For example the 1918 flu (pretty much identified as a swine variation) jumped from swine to human at time of low sanitation (trenches), large spread starvation, war (end of ww1, Russia civil war, China), and population disruption (troop movement). All of these variables came into place at the same time and FlU (one of the greatest killers of all time - -many believe this was one of the main kill off agents in the Americas) mutation created up to 100 mm (est 20 - 60 mm is more common).

SO despite the perfect conditions this pandemic was massive but no where near the kill off that the video suggests.

IN the Americas the native kill off was really a series of endless waves - Flu, black death, measles, small pox, etc that rolled and rolled with each disease taking more of the survivors. To create what you would suggest you would need a similar condition to the end of WW1 - (starvation, dirty trench static warfare, massive population disruption).
 
Given the destruction Japan would experience over the course of Downfall, there will probably be several different epidemics there, however, they would be very unlikely to spread outside of the Japanese archipelago.
