日本战犯榊原秀夫:曾协助731部队细菌战
这份1956年4月至5月的笔供显示，榊原秀夫1908年生于日本冈山县。1936年9月任驻伪满第1师团步兵第57联队附*医，1944年11月至1945年8月任关东*防疫给水部林口支部长。
重要罪行有：
“按照林口支部的任务，我在职期间，为准备细菌战，便命令第一课长细矢少佐实施细菌的保存培养工作”，以当时的生产量，“如撒布在中苏国境的东部地面，不但可以毁灭大量的苏联*队，同时亦达到足够毁灭中苏两国和平人民的用量”。
“为准备细菌战的捕鼠”，“我动员了部队全员进行从事捕鼠工作”
，“组织以间所少尉为长的约25名之常设捕鼠班”，“由于捕鼠工作的开始，先后送往第731部队去的老鼠总数是1945年4月1千只，5月1万只，6月8千只，7月7千只，合计为2万6千只”。
1945年3月上旬，“我根据第731部队的命令”，“把在支部保存培养着的伤寒菌、A型副伤寒菌的试验管2只，带到第731部队第一部*力检定班”，“这两种菌种，都是合乎第731部队第一部保存菌中的标准*力”，“为准备细菌战，它是适合于保存培养的”，“为了使它在井水中确有效力时，大约在井里放入一两个试验管，便可以达到屠杀的目的，我就是作了这样计划的”。“我因实验这种效能，杀害了4名中国的爱国人民。”
1945年4月，在黑龙江省安达县，“我是参加了在安达的杀人实验”，“4名中国爱国者”“被绑在安达演习场有相隔25米到30米的埋在地里的柱子上。”“一架轻(型)轰炸机飞到演习场上空，从150米的高度投下了陶器炸弹，在50米的空中该弹爆炸。”“我穿上了全套预防衣从五、六百米的距离观看了这种惨绝人寰的暴行。这个炸弹是填着可怕的炭疽菌的炸弹。让他们从鼻咽腔吸进绝对没有生存希望的肺炭疽，或因破片让他们发生皮肤炭疽，是一个特别残暴的罪行。我也是参加了这种罪行。”
1945年8月，“由广播得知与苏*开战，马上命令准备汽车出动，并将支部饲养动物除马外，即捕来的老鼠、白鼠、海狸、兔子、跳蚤及保存培养的细菌一并送交第731部队。”
“命令支队将所有房屋装上稻草，并准备足够汽油，以备待命烧毁”。“将卡车及所有器材一并烧毁”。“毁灭和破坏为准备细菌战的一切证据物件。”

the
1st
Division
in
the

September
1936.
From

to

1945，
he
was
head
of
the
Linkou
Branch
of
the
Epidemic
Prevention
and
Water
Supply
Detachment
of
the
Kwantung
Army。
Major
offences:
“According
to
the
mission
of
the
Linkou
Branch，
I
prepared
for
germ
warfare
during
my
term
of
office.
I
ordered
Section
Supervisor
of
the
First
Section
Major
Nishiya
to
do
the
bacteria
preservation
and
cultivation
work。”
With
the
production
volume
of
that
time，
“if
the
bacteria
were
spread
on
the
ground
of
the
east
section
of
the
China-Soviet
border，
we
would
have
enough
bacteria
to
not
only
destroy
a
sizable
number
of
Soviet
forces，
but
also
kill
all
the
civilians
in
both
China
and
the
Soviet
Union。”；
“To
find
enough
mice
for
germ
warfare”，
“I
mobilized
all
the
soldiers
to
catch
mice”，
“organized
a
regular
mice-catching
squad
of
25
soldiers
under
the
leadership
of
Second
Lieutenant
Madokoro”，
and
“after
the
catching
started，
the
following
numbers
of
mice
were
successively
sent
to
Unit
731:
1，000
in
April，
10，000
in
May，
8，000
in
June
and
7，000
in
July
1945，
totaling
26，000
mice”；
Early
March
1945:“I
followed
the
instructions
of
Unit
731”，
and
“brought
two
test
tubes
of
typhoid
bacteria
and
type-A
paratyphoid
bacteria，
which
had
been
preserved
and
cultivated
in
our
Branch，
to
the
Toxicity
Testing
Squad
of
the
First
Division
of
Unit
731”.
“The
two
bacteria
varieties
were
in
conformity
with
the
toxicity
standards
of
preserved
bacteria
set
by
the
First
Division
of
Unit
731.”
“They
were
ready
for
preservation
and
cultivation
for
the
germ
warfare。”
“To
ensure
its
effectiveness
in
the
well
water，
I
made
the
plan
that
only
by
putting
one
or
two
test
tubes
of
the
bacteria
into
a
well，
the
water
will
be
toxic
enough
to
kill
people。”
“To
test
this
effect，
I
killed
4
patriotic
Chinese
people”；
April
1945:
in
Anda
County，
Heilongjiang
Province，
“I
took
part
in
the
killing
experiment
in
Anda”，
“4
patriotic
Chinese
people”“were
tied
to
the
poles，
which
were
buried
half
in
the
proving
ground
and
placed
25
to
30
meters
apart
from
each
other”.
“A
light
bomber
flied
over
the
proving
ground，
dropping
from
150-meter
high
pottery
bombs
which
exploded
50
meters
above
the
ground。”
“Wearing
a
full
set
of
protective
clothing，
I
watched
the
whole
process
of
this
extremely
cruel
atrocity
from
5
to
6
hundred
meters
away.
The
bombs
were
filled
with
anthrax
bacteria，
which
were
inhaled
by
them
through
the
respiratory
tract，
causing
the
incurable
pulmonary
anthrax，
or
caused
cutaneous
anthrax
in
them
through
the
broken
pieces.
It
was
really
an
extremely
brutal
crime.
I
also
took
part
in
the
crime”；
August
1945:
“Learning
from
the
radio
that
we
were
at
war
with
the
Soviet
Army，
I
immediately
gave
orders
to
get
the
trucks
ready
to
deliver，
except
for
the
horses，
all
the
animals
kept
in
the
Detachment，
including
the
captured
mice，
white
mice，
beavers，
rabbits
and
fleas，
as
well
as
the
preserved
and
cultivated
bacteria，
to
Unit
731.”
“I
ordered
the
Detachment
to
cover
all
our
houses
with
straw，
prepare
enough
gasoline
and
get
ready
for
burning
everything
down。”
“All
trucks
and
equipment
were
burned
up。”
“Any
evidence
of
the
preparations
for
germ
warfare
was
destroyed。”
