FOREWORD

The United States Strategic Bombing Survey was established by tlic Secretary of War on 3 Novem-1944, pursuant to a directive from the late President Roosevelt. Its mission was to conduct antial and expert study of the effects of our aerial attack on Germany, to be used in connection withattacks on Japan and to establish a l)asis for evaluating the importance and potentialities of air

er as an instrument of military strategy, for planning the future development of the United States

d forces, and for determining future economic policies with respect to the national defense. Amary report and some 200 suppoiting reports containing the findings of the Survey in CJermany

been published.

On 15 August 1945, President Ti-uman requested that the Survey conduct a similar study of theof all types of air attack in the war against Japan, submitting reports in duplicate to the Secretary

War and to the Secretary of the Navy. The officers of the Survey during its Japanese phase were:

Franklin D'Olier, Chairman.

Paul H. Nitze, Henry C. Alexander, Vice Chairmen.Harry L. Bowman,J. Kenneth Galbraith,Rensis Likert,

Frank A. McNamee, Jr.,Fred Searls, Jr.,

Monroe E. Spaght,Dr. Lewis R. Thompson,Thoedore P. Wright, Directors.

W^alter Wilds, Secretary.The Survey's complement provided for 300 civilians, 350 officers, and 500 enlisted men. The

ry segment of the organization was drawn from the Army to the extent of 60 percent, and fromNavy to the extent of 40 percent. Both the Army and the Navy gave the Survey all possible assist-

in furnishing men, supplies, transport, and information. The Survey operated from headqvuirtersished in Tokyo early in September 1945, with subheadquarters in Nagoya, Osaka, Hiroshima andsaki, and with mobile teams operating in other parts of Japan, the islands of the Pacific, and the

c mainland.

It was possible to reconstruct much of wartime Japanese military planning and execution, engage-t by engagement, and campaign by campaign, and to secure reasonably accurate statistics on Japan's

omy and war production, plant by plant, and industry by industry. In addition, studies were

ucted on Japan's over-all strategic plans and the background of her entry into the war, the internal

ssions and negotiations leading to her acceptance of unconditional surrender, the course of health

morale among the civilian population, the effectiveness of the Japanese civilian defense organization,

the effects of the atomic bombs. Separate reports will be issued covering each phase of the study.

The Survey interrogated more than 700 Japanese military, government, and industrial officials.

also recovered and translated many documents which not only have been useful to the Survey, butwill furnish data valuable for other studies. Arrangements have been made to turn over the Siu-

files to the Central Intelligence Grouj), through which they will be available for further examination

distribution.

THE CORPORATION AND ITS IMPORTANCE IN THE AIRCRAFT

INDUSTRYduction

he Shoda Engineering Works (Shoda Scisa-a small independent manufacturing com-

of minor importance in the Japanese aircraft

tvy, consisted of a single manufacturing unit

d at Mitaka Township, in the Tokyoture, about 10 miles west of the Imperial

(Appendix A).

hoda pi'odueed cylinder iieads for less than

ercent of all aircraft engines made between1943 and August 1945. Specifically, it cast,

ed, lined, and rough-finished cylinderds for the Homare and Tempu engines.II June and July 1945, after the nearby Musashirks of tlie Nakajima Corporation was de-ed by bombing, Shoda heat-treated (quenched

annealed) connecting rods for Nakajima.g this period about 22,400 connecting rods

thus processed.n the non-aircraft field, Shoda inanufaclureil

us-sized nuts and bolts, 2-horsepower in-combustion engines used for portable

sets, and 13-liorsepower outboard and 40-

epower inboard engines for marine craft.

The company was established on 3 DecemberPrior to July 1942, production was limited

the non-aircraft field mentioned above. In1942 orders were received from the Muni-Ministry to establish a cylinder head casting

in addition to the then existing shops.

truction was completed and work beganthis plant on the first Nakajima order in

1943.

iovernment controls were largely localized.

Engine Section of the Aircraft Production

rd of the Munitions Ministry allocated mate-and production quotas; these details were

nistered by the local Kanto and Shinetsuict Offices of the Munitions Ministry.

or requirements wer(> obtained from theor Section of the Welfare Department.

Organization and Operation

The Shoda Company was individually ownedand operated by Jukichi Shoda. Capitalization,at the time of surrender, was about 4,000,000yen. The plant occupied a site of about 1,234,000square feet, of which 219,000 sc^uare feet wasbuilding area.

Industrial equipment consisted of 451 machines,

of the following categories:

Machine tools 305Electrical equipment 35Pneumatic machinery 32Metallurgical furnaces 55

Testing equipment 24

Employment in the Shoda Company increasedfrom about 800 in January 1943 to 1,850 at the

time of the suirender. These totals include all

employees no detailetl bri'ak-down data for air-craft and non-aircraft operations were available.

However, toward the end of the war, about 32percent of the total employees were engaged in

the manufacture of cylinder heads. Of this

amoiuit, about 28 percent worked on the 1930 to

0730 night shift and 72 percent worked on the

0730 to 1930 day shift.

The use of student labor was begun in April

1944; the proportion averageil about 23 percent

of the total. Soldier labor was used only in the

final 4 months beginning May 1945, varyingfrom 1 to 3 percent of the total employment

(Appendices B and B-1).

The Dispersal Program

Somewhat prior to the Munition Ministry's 4

April 1945 dispersal order to the Japanese aircraft

industry, Shoda had moved 36 sets of machine

tools to the nearby Yamamura Industry Com-pany's plant at Mure, in Mitaka Township.

Cylinder head finishing was carried out there.

Thirty-seven sets of machine tools were moved

to the Jindai Wood Works, at the village of Jindaiin Tokyo Prefectm-e. Macliine-finishing of the

1


8/23

radio set iiitenial combustion engines was donethere.

As a result of the onler of 4 April 1945, Shodapurchased a 60-acre tract of land at Shinkoji,

in Tsurukawa village, about 9 miles to the south(Appeiulix A). Shoda's plans were to move theentire plant to a combined underground-camou-

flaged factory at that location. Constructionwas begun in April, but imtil the surrender, onlythe access road had been repaired, about 100

yards of tunnel dug, and 84 machine tools movedto the dispersal site.

THE AIR ATTACKSAttack on Plant

The Shoda Engineering Works was neither se-lected nor attacked as a primary target. The

plant, however, sustained one air attack, an in-cendiary raid at 2230 hours on 25 May 1945,which was part of an area attack. Two lumbermills were completely burned and two woodwork-ing machines and some semifinished and finishedmaterial stocks were destroyed. The companygymnasium was damaged. However, no partof the company's cylinder head production shopswas hit or otherwise affected.

Attacks on Urban Areas

Attacks against the Tokyo- Yokohama urbanareas increased the difficulties which the companyexperienced in obtaining raw materials, the supplyof which had already begun to be erratic as earlyas January 1944 (Appendix C-1, 2, 3, 4). Short-ages of critical items (aluminum alloys, magne-sium, and copper) were felt by the aircraft indus-try before the air raids on Japan Proper but thedisruption of transportation delaj'ed the delivery

of what supplies existed and precipitated thedecline in production. From January 1944 tothe end of the war, only about 40 percent of therequirements for these items were received byShoda (Table 1).

PRODUCTION STATISTICS

Maximum productive capacity of Homarecylinder heads, from inception of casting opera-

tions in July 1943, rose steadily from 400 per

month until a constant montlJy figure of 4,000was reached in July 1944. Capacity for the

TempuHa23 cylintler head rose from an initial

200 per month in May 1944, to 400 in August1944, far below planned output (Appendix D-1,

2, 3).

Government ordei's for Homare cylinder headswere less than plant capacity until April 1944,

and except for a slight excess demand during thefollowing 3 months, very closely approximated

the capacity thereafter. In the case of the Tempuhead, government demands grossly exceededcapacity of manufacture at all times. In June

and July of 1944, this excess was more than 650percent of plant capacity (Appendix D-2).

Actual production of the Homare head in-creased steadily until July 1944, when a maximumof 4,032 units were made, anil gradually declined

thereafter. Actual production reached the

planned and capacity level in only that 1 month(Appendix D-1). This difference between planned

and actual production was due to (a) failure ofthe Munitions Ministry to provide promised

blowers and melting and drying furnaces, and

(b) shortages in supply of aluminum and alumi-num alloy stocks.

The production project of the Tempu head wasa complete and dismal failure because machinetools and equipment promised by the Ministryof Munitions could not be obtained. This project

accordingly was discontinued after December 1944.The Tempu cylinder heads also were principallyfor trainer planes and due to the increasing needfor larger engines, this factor may have enteredin to bring al)out the rlecision to

abandonits

production.

A contributing factor to production slow-downswas the increasingly frequent air attack alarms.During these alerts, workers sought shelter and

work was suspended.

EVALUATION OF PRE-ATTACKINTELLIGENCE

Joint Target Group information on the ShodaEngineering Works was uncertain and incom-plete. Joint Target Group reported: (n ) traineraircraft and aircraft engines produced by the


9/23

dii Aiicral't Company but, in tlic .saiiic scii-qualidcil this statement by suggesting only

manuraetiirc and subassembly opei'atioiis,

the Mitaka Aircraft Company and Nakajimaperimental Station at this approximate location,

(e) Mitsubishi taking over the Shoda plant.

The following findings were determined to beet, in contrast to the intelligence data

d above: (a) No trainer aircraft, aircraftes, or subassemblies were produced by

a. (b) Mitaka Aircraft Company was anpendent organization, located adjacently to

Shoda plant. Air Photo of Joint Targetup Information Sheet shows both companies

ed as one unit, (c) There was no Nakajimaerimental Station located at or near this site.

Mitsubishi had no interests in the Shodaipany.

Although this Joint Target Group Informationwas incorrect in its data as to exact location

activities of Shoda, no serious omission re-

d since it correctly analyzed Shoda as oc-ying a relatively unimportant position in the

aft industry.
