Question: What quantity of germs of each of the principal infectious diseases could
Detachment 731's 4th Division produce in one month?

Answer: That is a rather difficult question, but I would say that if its production facilities
and all its equipment were operated at maximum capacity, the 4th Division could produce in
one month: 300 kilograms of plague germs, or 800 to 900 kilograms of typhoid germs, or 500
to 700 kilograms of anthrax germs, or one ton of cholera germs.

Question: Will you describe the equipment of the 4th Division?

Answer: The 4th Division had two production units, both of equal capacity.

Question: What was the capacity of the first unit's boilers, in which the culture medium
was prepared?

Answer: It had eight boilers, each of one-ton capacity.

Question: That means that one of the 4th Division's units could produce eight tons of
culture medium at one operation?

Answer: That is so.

Question: And what was the aggregate capacity of the boilers of the second unit?

Answer: The same.

Question: How many culture chambers were there in the first unit, and how many in the
second?

Answer: Five in the first, four in the second.

Question: Who designed the cultivators for the breeding of germs?

Answer: The cultivator was invented by General Ishii.

Question: How many Ishii cultivators did the 4th Division have in all?

Answer: I don't remember exactly, but quite enough for the mass production of germs.

Question: When you spoke of the potential output of lethal germs, on what did you base
your figures?

Answer: The capacity of the boilers and other equipment, and the number of cultivators.
