Question: State more explicitly when Detachment 731 was set up.

Answer: I do not remember exactly when Detachment 731 was formed. As far as I can
recall, Detachment 731 was set up in 1934-36 in accordance with a decree of the Emperor of
Japan.

Question: Since when did you work as Chief of the 1st Operations Division of the
Kwantung Army Headquarters?

Answer: I worked as Chief of the Operations Division of the Kwantung Army
Headquarters beginning with August 1943.

Question: Did you have any relation in your line of duty to the work of detachments 731
and 100 connected with the production of bacteriological weapons?

Answer: Yes, as Chief of the Operations Division I was connected with the work of
bacteriological detachments 731 and 100 of the Kwantung Army. Concretely, this connection
consisted in that reports by the chiefs of detachments 731 and 100 on various problems
connected with the development and production of bacteriological weapons came to me, as
Chief of the Operations Division. As a rule, these reports were addressed to the Commander
of the Kwantung Army, but insofar as they related to the work of one or another service the
Adjutant Division (the secretariat) sent them to the appropriate division.

Reports having a bearing on the work of the Operations Division, that is, connected with
the practical employment of bacteriological weapons, came to me. Reports connected with
the employment of bacteriological weapons for sabotage were sent to the Chief of the
Intelligence Division.

Upon receiving such reports, depending upon their importance I either settled them myself
or else reported to the Chief of Staff of the Kwantung Army or to the Commander, at first
Umezu, and later, beginning with July 1944, Yamada.

Question: In your testimony of November 16, 1949, you spoke about instructions which
the Kwantung Army Headquarters received from the Japanese Ministry for War to increase
the production of bacteriological weapons in detachments 731 and 100. State more explicitly
when these instructions were received.

Answer: I cannot now recall the date when the Kwantung Army Headquarters received
these instructions. I remember that it was either in spring or summer, but whether in 1944 or
1945 I do not remember exactly. I remember that in line with these instructions the
Commander of the Kwantung Army, it was either Umezu or Yamada, instructed Detachment
