named Kaneko Junichi in a disser tation for his PhD at Tokyo University. In
his chart of the effectiveness of six types of biological warfare operated by

Unit 731 from June 1940 to August 1942, it was ver y clearly stated that the

[41]
plague outbreak peaked by day 10. Besides bubonic plague, anthrax and
glanders were also used. Villagers in the region suffered from rotten leg
[42]
diseases for many years aer the war.

Another incident described, “… in the summer of 1941. One day,
nd
Colonel Oota, Chief of the 2 Division, told me that he was going to Central
China and said goodbye to me. Sometime aer his return he told me that

plague eas had been dropped from aircra on the Chines e in the area of

the city of Changteh, near Lake Tung Ting Hu, in Central China. is, in

effect, was a bacteriological attack, which was the ter m he used. Aer this,
Colonel Oota made a report to Chief of Detachment 731 Ishii, at which I

was present, to the effect that the Det achment 731 expedition had dropped

plague eas from an airplane in the Changteh area, and that an outbreak of

plague epidemic had resulted, a number of persons being stricken with the

disease, but how many, I do not know.” e incident des cribed by
Kawashima was done by an expedition of 40-50 men who sprayed plague

[43]
eas from aircra at a high altitude.

From their research, they came out with the designs of thes e bacter iological

bombs.
