SUBJECT: Re Investigation of the Osaka Main POW Camp.
By direction of the Chief, Investigation Division, Lt. J B Ammon
and Lt. S. Walters, accompanied by T/4 Toda as interpreter, proceeded
to Osaka and made an investigation of the Main POW Camp there.
(The report to supply information for the prosecution of War
History of the Osaka Main Camp - 21 September 1942 the Osaka
Main Camp was established at Chikko. The POWs remained at Chikko
until 1 June 1945, when the camp was bombed out. They moved to
Tsumori Camp (the description and report on this camp was given
in a previous report). Tsumori was considered to be in an unsafe
location, so the POWs were transferred to Kita-Fukuzaki. On the
10th of July 1945, the main office was separated from the camp.
The camp was then called Osaka 1st branch. The main office was
moved to Shimo Shinden, Shinden-mura, Mishima-gun which is about
five miles north-east of Osaka. Chikko, Tsumori and Kita-Fukuzaki
are all in the city of Osaka.
1. Location: See enclosed exhibits for exact location of these
Military Objectives - all three locations of this camp were situated
along the Osaka waterfront and in the midst of vital military
objectives. Both Tsumori and Chikko were bombed and burned completely
and Kita-Fukuzaki was damaged.
2. Description: The camp at Chikko was bombed and burned flat,
and only the foundations of the buildings remaim. The camp consisted
of several wooden buildings coverfed with mud stucco. Overall
dimensions of the camp were 230' x 130'.
POW quarter consisted of two one story barracks, each 72' x 33'
in size. These two barracks had triple decker bunks. A third
building 72' x 30' was of two story construction. A space on
the first floor 30' x 24' was used solely as a sick ward. The
second floor contained POW quarters. A fourth building 64' x
30' quartered POWs on the second floor only.
The kitchen was 30' x 30' and had eight brick stoves. There was
a cement bath 10' x 10' and ten showers. The dispensary was a
room 21' square and next to it was the guard house and one cell.
The remaining space were the Japanese quarters, kitchen, idining
room and latrine.
For air raid protection, there was one shelter in the middle
of the camp 45 ft long and 12 ft. wide and five small shelters
around the outside of the camp. Each of these was 15 ft. long
and four ft. wide. This was not adequate for the number of POWs
On 2 June 1945 the POWs transferred to Tsomori Camp (this camp
had already been covered in a previous report). On 10 July 1945
they were again transferred to 7 Nishino-sho, Kita-Fukuzaki,
Minato-ku in Osaka. Here they were quartered in three rooms on
the second floor of a large warehouse. Each room was 55' long
and 40' wide with cement floor and cement walls, with a low-ceiling
only about 5 feet high in some places. On the first floor of
the warehouse was the guard house, 15' x 15'. the dispensary
15' x 15' and the sick ward, 30' x 15'.
Outside the warehouse was the kitchen, a wooden building built
by the POWs. It contained 4 brick stoves and 1 brick oven. Next
to the kitchen was a large cement water tank for fire fighting.
The latrine was a wooden structure built by the Prisoners and
consisted of 2 urinals and 16 toilets. The location of the camp
was not nearly adequate for the number of prisoners. Sleeping
quarters were very cramped ad no shelves or tables were provided,
the POWs slept on mats thrown on the cement floor. The latrine
and kithcen facilities were very poor and no sanitary conveniences
were provided. The POWs remained here until the end of the war.
3. Utilization: The Osaka Camp was established to provide workers
for the docks and stevedoring companies of Osaka Port.
Clothing: The prisoners had their own clothing plus Jap uniforms.
Their shoes were either their own or Jap army shoes, some PWs
were issued the rubber soled sneakers. The Prisoners operated
a shoe repair shop in the camp.
4. Prisoner of War Personnel: The prisoners arrived 11 October
1942- they were British from Hong Kong and were 500 in number.
They came from Hong Kong on the Lisbon Maru.
5. Guards: For a complete roster of the Japanese Army Personnel
at this camp see the attached Exhibit. [no roster attached]
6. Work: All the prisoners from the camp worked for various transportation
and stevedoring companies of Osaka Port. They loaded and unloaded
ship, transported materials, worked in warehouses and loaded
and unloaded railroad cars at the docks, They worked on all kinds
of goods, usually foodstuff and clothing. Some military equipment
consigned to Jap armies in the South Pacific.
0800 started work
1200 - 1300 lunch
1600 - quit
During the day they got breaks depending on the job they were
Some of the working places were close to the camp others far
away. At Tsumori the POWs were ferried to the docks to work.
At Kita-Fukuzaki, they were transported by street car or bus
to the dock area.
Pay: 1 Yen per day of which the PW received 20 sen. [100 sen
= 1 Yen] [So the Japanese claim- no pay
was given to any extent]
Red Cross: During the entire time the camp was open the Prisoners
only received one-third of a Red Cross package. (No facts were
obtained on what became of the rest of them).
7. Food: A sample day's ration as follows:
Breakfast - Rice and soup
Lunch (carried by the PWs to work) Rice, sometimes bread, seaweed.
Dinner - Rice and soup, fish every 10 days, meat once or twice
a month; vegetable (one kind each night) onions, potatoes, radish,
cabbage or eggplant. [Again, so claimed
by the Japanese]
8. Medical: The medical staff consisted of: 2 Jap doctors,
2 PW doctors, 1 PW dentist, 10 Jap medics, 5 PW medics. The medical
supplies were furnished by the army.
C E R T I F I C A T E
An average of 70 men per day could not go to work because of
sickness: 15 beri beri, 10 skin diseases, 15 dysentery and 30
from colds and pneumonia. (These average figures given us by
a Jap army doctor of the camp.)
25 men died at this camp. 10 from pneumonia and 14 from beri
beri. Some of the worst cases were removed to Ichioka Hospital
just before they died. [Not counted in
camp total] Some of these deaths were due to the weakened
condition the prisoners were in when they arrived in Japan.
9. Sanitation: See 2 above (Not able to see much on this because
of the bombed condition of the camps)
10. Air Raid Protection: See 2 above (the roofs of the buildings
were not painted until the war was over)
11. Punishment: No evidence of any beatings taking place at this
camp [Note- this information obtained
from former Jap staff of the camp after the war and after the
POWs were sent home]
12. Conclusions: a total of nine former Jap guards at this camp
were interrogated but no evidence of atrocities was uncovered.
We, S Walters Lt., O-1332112 and J B
Ammon Lt., O-1185962 certify that the above mentioned facts are
as we saw or as were told to us during our investigation of the
Osaka Main Prisoner of War Camp. This investigation took place
11-12 February 1946.
