INTRODUCTION

This summary of the natural resoarces of Japan gives an overall
view of aJi island country, somewhat smaller than the state of California,
which has a homogeneous population of about 76,000,000 concentrated in a
relatively few small lowlands. In this report are analysed, in a broad
way, the two main categories of geographic factors: The natural environ-
ment on the one hand, and cultural occupance on the other. In consider-
ing the inter-relationships between these factors, the report depicts
the adjustment of a dense population to an environment which is favored
by a healthful climate and productive fishery and forest resources, but
subject to limitations imposed by its small land area and restricted
mineral and agricultural resources.

This treatment may clarify a question often raised: Japan is on the
road back: — but to what? A definitive answer is difficult, yet an outline
of the economic course along which Japan must travel in the years immedi-
ately aihead can be charted when its natural assets and limitations are
understood.

Many details have been omitted he-^-* because Section II and III are
designed to accompany oral presentatio. i The last two sections, which
are intended for perusal after such ori ntation conferences, will supr^ly
reference data for those who wish to pursue the subject further.

(JEKERAL GEOGHAPHY

1. DEFINITION AND POSITION OF JAPAN PROPER

a. Japan Proper, as defined by SCAP Memoranda to Japanese
Government, 29 Jan and 23 March 46, (See Plate l) consists of four islands:
Hokkaido ("North Sea District"). Honshu ("Main Island"). Shikoku ("Four
Provinces"), and Kyushu ("Nine Provinces"), and the approximately 1.000
adjacent small islands.

b. Islands and island groups included in Japan Proper:

(1) Sado

(2) Tsu Group

(3) OkuBhiri

(4) Izu Group, including Sofu-gan

(5) Oki Group

c. Islands and island groups excluded from Japan Propers

(1) Utsuryo (Ullung) , Lianoburt Rocks (Take), and i^uelpart
(Saishu or Cheju)

(2) Ryukyus Group south of latitude 30° N

(3) Kuchino , south of Kyushu

(4) Nanpo Group

(5) Bonins (Ogasawara) Group

(6) Volcano (Kazan or I wo) Group

(7) Kurils (Chiehima)

(8) Habomai (Hapomaze) Group (off NE Hokkaido)

(9) Shikotan

(10) All other outlying Pacific islands

d. Japan is a mountainous island festoon off the coast of Asia.

(1) Climatic consequence: Marine climate, monsoons, many
variations owing to difference In altitude

e. The Latitudinal spread (30° to 45° 30' N) is comparable to
that from Florida to Maine (See Plate 1 Inaet).

(1) Climatic consequences Subtropical in southern Khushu
to cold winters, mild summers in Hokkaido

3. SURROUNDING WATERS

a. Deep water is comparatively near shore around the islands.
Single exception is the sea off northern Kyushu and southwestern Honshu.
Limited coastal shelf, hence limited opportunity for bottom fishing.

b. Japan lies at zone of conrergence of two water masses, the
cold waters of the northwestern Pacific, and the warm-surfaced mass known
near the islands as the Kuroshio, or Japan (or Black) current (Plate 2).

(1) The Japan current moves slowly northward from the
equator, divides south of Kyushu, one branch to the
Japan Sea, and the main mass eastward along the south-
ern shore of Honshu. Late summer temperature averages
82 P; late winter temperature 68°

(2) Japan current met by cold waters off northern Honshu,
known as the Oya current on the Pacific side. This
water less salty than Japan 'current , and tenqperature
rarely rises above 65°, even in summer. Winter temper-
atures may approach freezing point.

c. Effects of water masses

(1) Contrast between climates of Hokkaido and other parts
of Japan. Japan current favors mild winters and high
precipitation for Honshu, Shlkoku, Kyushu.

(2) Great variety and abundance of marine life.

8. SOILS (See plates 6 and 7)

a. Origin and distribution

(1) Mineral soils are derived from igneous, volcanic, and
sedimentary rocks, volcanic ash, tuffs, alluvial and
colluvial materials, and unconsolidated marine sedi-
ments. Peats (bog soils) are formed from residues of
decayed vegetation of mafshlajid species. Most areas of
peat soils are in Hokkaido and northern Honshu.

(2) Thin, stony soils (Lithosols) of rugged hill and moun-
tain areas predominate throughout Japan. They are
chiefly forest lands.

(3) The best agricultural soils are centered in a number of
wide plains and extend into rougher areas along stream
valleys and on lower slopes. Such soil areas comprise
only 18 percent of the total area of Japan.

(4) Sandy soils are distributed along almost all sea coasts.

b. G-eneral soil characteristics

(1) Most of the agricultural soilB are loams and silt loams
physically suited for tillage.

(2) Natural fertility is low. Even soils of high humus con-
tent require heavy fertilization annually for high
yields. Soils from volcanic ash are particularly low in
phosphate. Essentially all of the agricultural soils
respond well to proper fertilization; nitrogen and
phosphorous are the elements that give the largest yield
increases for most crops.

(3) In general, the upland soils are moderately to strongly
acid. The alluvial soils are only slightly acid, par-
ticularly if used as rice paddies.

c. Fertility gtatuB

(1) The soil fertility trend i-s upward on the ag-. •■ultural
lands.

(a) A large proportion of the crops harvested is re-
turned to the land as night soil, animal manures,
mulches, and composts.

(b) Importation of food and the use of fish, seaweed,
and similar marine products in the diet are in-
direct sources- of additional soil nutrients.

(c) Large importations of fertilizer materials, es-
pecially phosphate (about 1,000,000 metric tons
annually during 1936-40) , and fixation of atmos-
pheric niftrogen as nitrogenous fertilizers' (400,000
metric tons of nitrogen annually during 1936-40)
add greatly to the soil nutrients supply.

(d) Vegetation is removed from non-arable land and
applied to agricultural land as compost and ashes.

(e) Leaching of plant nutrients is partially compen-
sated by nutrients in irrigation waters.

(2) The soil fertility trend is downward on the non-arable
land.

(a) Forest products are removed for lumber and fuel.

(b) Grasses and shrubs are removed for feed and com-
posts .

(d) Ho replacement of any consequence is made.

(e) Sheet erosion is favored for periods on many forest
lands by clear-cutting practices.

d. Irrigation, drainage t and erosion

(1) Irrigation is practiced on most of the soil areas used
for the production of rice and many of the areas where
vegetables are grown. Irrigation makes possible the
utilization of drouthy soil areas. Even steep hillsides
are used for the production of paddy rice. Stream di-
versions furnish about 65 percent of the water for irri-
gation. Reservoirs, lakes, and ponds supply most of the
remainder, bat wells are also used.

(2) Drainage has been important in reclaiming agricultural
soil areas from shallow lakes, bays, and swampy areas.
It has also increased the productivity of some poorly
drained areas, formerly adapted only to the growth of
rice, by increasing the yield of rice and making possible
the growth of a winter crop such as wheat or barley.

In naturally better drained sites, where the climate is
suitable, it is the practice to drain the rice paddies
in the fall eind grow winter crops on these areas.

(3) Water erosion is active on many of the non-arable, hillyj
and mountainous areas of southern Honshu, Shikoku, and
Kyushu. Some areas are nearly barren and badly gullied,
while many others have lost considerable surface soil by
less obvious sheet and rill erosion. Wind erosion is
reTiorted to be active in some dark colored, volcanic
ash-derived soil areas during certain seasons unless
adequate precautions are taken following cultivation.

(2) Agriculture in Japan gardening rather than farming

(a) Mo8t work done by ha-nd with primitive tools, but
these tools well suited to their use

(b) Production per unit area high but production per
man low

1. Practiced widely in central and Bouthwestem
Japan

2. Area under cultivation enlarged one- third by
multiple cropping

c. Land development

(1) History

(a) Land reclamation increased the arable land area of
Japan seven percent or 896,000 acres from 1910

to 19r59. The arable land in 1939 was 14,750,000
acres. The arable land area decreased three per-
cent or 432,000 acres from 1939 to 1944, chiefly
owing to military and industrial uses of land.

(b) Progressively the er-pansion of the arable land area
has become more difficult. Land now under culti-
vation includes most of the more productive agri-
cultural areas of Japan.

(2) Present reclamation potentials

(a) An estiiated 3,900.000 acres of additional land
could be brought under cultivation by the ex-
penditure of cooperatively large amounts of capi-
tal, labor, and materials. After being reclaimed,
much of this land probably would be marginal.
Reclamation of such an area would add 25 percent
to the present arable area of Japan.

(b) Production on large areas of the cultivated land
in Jap«n can be increased by grading, irrigation,
drainage, and storm and flood protection.

d. Agricultural production

(1) Six crops furnish 85 to 90 percent of calories in
Japanese diet from indigenous sources: rice, wheat,
barley, naked .barley , sweet potatoes, and white potatoes

(2) Rice dominates agricultural economy.

(a) Rice occupies- approximately 53 percent total culti-
vated area, and about 42 percent of total crop area.

(b) About 96 percent of rice grown in irrigated lowlandB

(c) Rice better adapted than other cereals to long grow-
ing season, high summer temperatures, and the heavy-
rainfall in Japan.

(d) Wheat and barley, next in importance, require
temperate climatic conditions, i.e., grown in summer
months in northern Honshu and Hokkaido, but in
winter months in central sind southwestern Japan.

(e) Sweet potatoes limited largely to area south of lati-
tude 38° N. , while white potatoes grown extensively
north of 38° N

(3) Sericulture suited to Japan because of mild winters,
humid climate, and abundant supply of cheap labor

(a) Northern limit approximately latitude 40° N

(b) Limit determined by winter survival of mulberry

(4) Tea production extends north to about latitude 37° N.

(5) Livestock of minor importance in Japan

(a) Production livestock products requires four to six
acres to produce as many calories as can be obtained
from one acre of cereals.

(b) Japanese depend on fish and plant sources for most
of their proteins.

Research

(1) 424 institutions have primary function of agricultural
research.

(a) Research conducted by imperial auid pref°ctural ex-
periment stations, imperial vmiversities , prefec-
tural agricultural colleges, private institutions,
and corporations.

(b) Experiment stations are small and highly specialized.

(2) Application of results of research has caused significant
increases in agricultural production.

(a) Yield of silk per hectare increased 400 percent
from 1890 to 1940.

(b) Yields per unit area of rice, wheat, common bardey,
and naked barley increased about 70, 140, 119 and
62 percent, respectively, from the 1878-82 period
to the 1938-42 period.

2. FISHERIES (See Plate'll)

a. General statement

(1) Prior to World War II Japan was the foremost fishing
country in the world.

(a) Annual catches in home waters were 2,500,000 to
3,500,000 metric tons; catches overseas Including
those of colonial waters amounted to an additional
2,000,000 to 3,500,000 tons. Total Japanese pro-
duction of marine products accounted for more than
one-fourth of the world's total.

(b) Full-time and part-time fishermen in Japan numbered
about 1,500,000.

(d) Japanese fishing operations were world-wide.

(2) Fishery products provided most of the animal protein in
the Japanese diet.

(3) Although the greater part of the Japanese fishing pro-
ducts were consnaed at home, the production' provided
needed exports for JapsJi's trade balance.

b. Explanation of emphasis' upon fishing in Japan

(1) Dense population with meager food resources

(2) Insular character and great length of coastline

(3) Coastal concentration of the population

(4) Excellent fishing grounds where warm and cold ocean
currents converge

c. Fishing regions

(1) Coastal and offshore waters of Japan Proper

(a) Cold", waters surrounding Hoklcaido and Kuril I elands

(b) Temperate, waters off coasts of Honshu, K.2''^3hu,
and Shikoku

(d) Deep-sea: Pacific Ocean east of Japan

(a) In addition to fishing in waters near the Home

lelanda and former colonies (including thn mandated
islands) , Japan operated salmon and crab fisheries
in northern waters of the Oknotsk and Bering seas,
trawling in the East China and Yellow seas, whaling
in Antarctic waters, and small scale fisheries off
the coasts of Alaska, British Columbia, Mexico,
Central America, and South -"^merica of the V/estern
Hemisphere, and in Indian and -fiustralian waters of
the Far East .

d. Ports

(l) The fisheries of Japan are conducted from many small and
a few large ports scattered along the coasts of the Home
Islands. Some important ports which serve as bases for
large-scale operations are Hakodate, vhoehi, Shimonoseki ,
Tobata, and Nagasaki.

e. Marine products

(l) Japan produces a great variety of marine products for
food. Several hundred different species of fish alone
are eaten in Japan. Among the important edible products
are!

(a)

Sardines

(b)

Herring

(c)

God and flounder

(d)

Cuttlefish

(e)

Aquicult

ure

(l) The practice of aquiculture (culture of fish, shellfish,
and seaweed) is nighly developed and illustrative of the
importance attached to fisheries by Japanese. Species
raised include carp, eel, oyster, clam, and seaweed as
well as trout and otner fresn water fish. The output
from tnis production contributes considerably to the
food supply.

g. Research and education

(l) In keeping with the importance of marine products in the
economy of Japan, much emphasis is placed on fishery re-
search and education. Japan has 143 research stations,
32 prefectural schools, two colleges and three departmenti
In Its imperial universities which deal with fisheries.

a. Importance of forests

(l) Japan depends on her forests to furnish lumber euid

timbers, provide pulpwood smd veneer logs, produce fuel,
regulate stresun flow, maintain water tables, prevent
serious floods, minimize soil erosion, and supply food
and other products.

spite recent industrial progress. Ninety-nine
percent of the population lives in wooden houses;
in cities like Tokj-o, only one percent of the
1,100,000 prewar buildings was constructed of
materials other than wood. In industry, rayon
manufacture depends entirely on wood pulp for fiber.
Fishing fleets are coEposed mainly of wooden ships.

(b) Occupation Forces; Requirements for troop and
dependency housing: 500 million board feet.
(This requirement, wni ch represents about eight
percent of lumber smd special timber production,
was virtually completed by 1 January 1947.
Additional requirements are expected to be small.)

Total prewar houses 16,000,000

Estimates of construction requirements are calcu-
lated 15 tsubo (534 square feet) per house, re-
quiring about 4,800 board feet. From 2 September
1945 to 1 January 1947, 300,000 houses requiring
1 i500, 000 ,000 board feet are reported to have been
constructed. (Note! Many emergency structures
r'equlring 2,400 board feet or less have been built.
However, many other buildings, such as theaters,
dance halls, restaurants, or shops requiring muc;h
more lumber per structure have been built with
black-market lumber.)

Lack of repairs, replacements, lubricants, and.
sometimes electric power are the principal causes
for non- operation.

feet annually
Occupation Forces requirements: 35 ,000,000, square

Production - 1946: 128,000,000 square feet

One-fourth of Japan's i535 veneer and plywood
plants were damaged or destroyed during the war.
Shortage of materials holds the industry to about
one-half rated capacity.

(f) Pulpwood

1.. Wood palp mi 11b in Japan consume much less

wood than other wood-using industries such as
lumber and charcoal. Prom a total annual
growth per year of 1,693,000,000 cubic feet,
only a little over 30,000,000 cubic feet were
consumed in 1946 by the wood pulp industry.
However, the volume of ./ood consumed annually
for a seven-year period up to 1944 was approxi-
mately 120,000,000 cubic feef, consequently a
substaoitial increase in the use of pulpwood
is essential for the future cultural expansion
in Japan. The preferred species are the
spruce and fir (yszomatsu and todomatsu),
which grow abundemtly in Hokkaido, and the red
and black pines (akamatsu and kuromatsu) of
Old Japan. Other species used for pulping
include beech and hemlock.

2. A substantial increase in the rayon incuetjry
is essential and the production of icraft pulp,
both unbleached and bleached, will become a
necessity if Japan is to have strong papere of
relatively high quality.

3. The following table shows the 1946 production
of the various types of pulp produced and the

g. Forest Hesearch

(l) Forest research covers a wide range of activities,

including utilization, protection, soils, silviculture,
technology, management, meteorology, and by-products.
Japanese re-searchers are fully conscious of the desira-
bility of improving forest areas and utilit'-ation of
the products. Some projects do not give the impression
of having immediate practical value until it is real-
ized that there are ehortaj^es of many commodities in
Japan, necessitating development of substitutes.

(2) Forest erperimant stations have been established to
conduct programs under the supervision of the Imperial
Household, national and prefectural governments and
universities. Forest product experiments are pursued
by private industrial laboratories seeking better uti-
lization practices in their manufacturing processes.

(3) Forest experiment stations are located at:

(a) Imperial Forest and Estates Bureaui
Tokyo end Hokkaido

(b) Bureau of Forestry, Ministry of Agriculture and
Forestry, Tokyo

(d) Imperial Universities: Hokkaido, Kyoto, Kyushu
and Tokyo

(e) Industry: Several major wood using manufacturers
have established private wood products experiment
laboratories

4. MISEBALS

a. Japan Poor in Mineral Resources

(1) In all except a few commodities the resources and pro-
duction are inadequate for her own needs. Japan did,
however, build a large i^efinlng and processing industry,
which, although dependent on imports of raw materials,
yielded finished products for her own use and for ex-
port.

b. Inadequate Mineral Resources

(1) Petroleum (See Plate 12)

(a) Three major producing areas - Akita, Yamagata,
and Niigata districts in northwestern Honshu

(b) Present production about 1,400,000 barrels froiL
about 4,000 producing wells. This production is
about 10 percent of civilian requirements in 1935.

(2) Lead, manganef^e, tungsten, molybdenum, fluorlte, nickel,
cobalt, antimony, mercury, vanadium, titanium, iron,
asbestos, graphite, gypsum, tin and other minerals are
produced in insufficient quantities. No phosphate,
potash, or rock salt. Pan salt is produced in suf-
ficient quantity to provide for about 50 percent of
Japanese needs. Lack of phosphate and potash is

particularly critical in view of the large quantities
required for fertilizer.

c. Adequate resources (See Plate 13)

(1) Copper: Production has exceeded 70,000 metric ton* of
refined copper per annum from 1935 to 1944, inclusive.
Eighty percent of production from mines in Honshu.

(2) Zinc: Production of refined zinc has exceeded 22,000
tons each year since 1935. Ninety percent of productior
from Honshu.

(3) Gold: Recent production of gold has been about 3.8
tons per year. The production has come from many widely
scattered mines.

(4) Silver: Production has exceeded 200, .000 kg since J.935.
Japan was seventh in world production.

(5) Arsenic: Since 1935 production has exceeded 2,000 tons
per year which is approximately enough for insecticides
and other normal needs.

(6) Chromite: Since 1935 production has exceeded 33,000
metric tons annually. Nearly all production has come
from southern Hokkaido and southern Honshu.

d. Resources in excess of needs (See Plate 14)

(1) Coal: The Japanese coal reserves have been estimated
at 16,000,000,000 metric tons, of which 93 percent is
bituminouE, 4 percent semi-anthracite, and 3 percent
lignite; peak production of 57,000,000 metric tons in
1940 was achieved under government subsidy and is not
an index of peacetime producing capacity. The princi-
pal coal fields are:

(a) Northern Kyishu fields produce over one-half total
output

(b) Hokkaido fields, chiefly Ishikari

(2) Sulfur and pyrite: Sulfuric acid production is esti-
mated to have reached a maximum of 3,800,000 tons in
1943.

(3) Cement: During the war Japan produced more than
4,000,000 metric tons per year.

(4) Water resources: The Japanese have large resources of
water and have utilized their surface water to a high
degree.

(a) Streams are short, with high gradients; becaase of
large rainfall, they carry a large volume of water.

1.. Electric power potential for Japan Is esti-
mated at 10,000,000 kw

2. Largest hydroelectric plant is on the Shina.no
river at Tomaru-mura , Niigata Prefecture -
165,000 kw

3. Many small-scale irrigation projects

e. Plant Capacity for Smelting and Reduction in Exce«s of Needs

(1) Steel: 6,887,000 metric ton maximom production in 1943
To achieve sufficient production, imports of high-grade
iron ore or pig iron were necessary.

(2) Ferroalloys: Capacity proportionate to steel capacity

(3) Sulfuric acidl 3,800,000 metric tone maximum pro-
duction in 19-^2,

(4) Magnesium: 2,903 metric tons maximum production in
1944

(5) Aluminum: 114,057 metric tons maximum production in
1945

(G) Superphosphate: 1,639,000 metric tons maximum pro-
duction in 1939

(7) Copper refining: 122 ,000 metric tons maximum production
in 1943

f . . Research and Education

(1) Research in mining and geology is on a small scale com-
pared to similar research in the United States. The
relatively low potential of scientific personnel made
it necessary for the capable Japanese scientist to
divide his efforts between numerous assignments. The
Imperial universitiee, where most Japanese scientists
receive their training, are inferior to the average
American state university in both faculty and ecjuipment.
Research lacks continuity between the academic and
applicatory phases.

(2) Scientific research in Japan ie largely under the con-
trol of the Japanese government throrgh agencies within
the Ministry of Education and government ownersliip.

(3) Important research institutions are the Imperial G-eo-
logical Survey, the Imperial Universities of Tokyo,

, Hokkaido, Tohoku, -Kyoto, and Kyushu, and laboratories
of, the Mitsubishi Mining Company, Ltd. Researches in
sciences related to mining and geology are made at the
Yawata Technical Research Institute and other metallur-
gical laboratories maintained by the Japan Iron and
Steel Company, Ltd, the Japan Steel V/orks , and the
Kobe Steel Works, the Institute of Physical and
Chemical Reseiarch, the Chemical Industrial Research
Laboratory, and the Imperial universities.

5. WILDLIFE

a. Although wildlife was well protected in feudal days, in-
craasing territorial pressure from the axpanding human population has
caused it to decline steadily since 1868. Heedless exploitation during
World War II brought all wildlife to a critical state. Many species of
economic and scientific value are in danger of extermination.

b. The decline in receipts from wildlife in the last two
decades has been marked. Ninety-five percent of the 200,000 licensed
hunters in 1925 made all or a major part of their living hunting. Today,
with only half the number of hunters, none is able to earn his living from
it. A small ducte-netting preserve now averages 5,000 ducks a year. In
1926 it produced 200,000. Up to 1925 one village in Gifu Prefecture mar-
keted 500 barrels of pickled thrushes annually. It lias had none to ship
since 1942. Japan abrogated the International Fur Seal Treaty in 1946 and
has conducted legal pelagic sealing since. Even this has been insuffi-
cient to bolster receipts from the overworked fur industry.

c. The mediaeval game laws ,- unchanged since 1922, never favored
a sustained annual yield. A six-month open season, spring killing, and
sach destructive hunting methods as netting, trapping, and liming were
allowed. Species protected elsewhere in the v/orld as insect destroyers
and song birds were slau^^i^tered for food and sport. Lax enforcement
nullified what good those laws might have done. The "balance of nature"
has been badly upset, as insect epidemics attest. After stripping the
guano, sea-bird colonies were despoiled by egging and shooting, prevent-
ing future deposition of fertilizer.

d. Strict conservation measures are needed to restore wildlife,
regain the T3enefitB formerly harvested from it, and establish a sustained
yield. Corrective regulations have been promulgated by the Ministry of
Agriculture and Forestry.

Section IV

HAW MATERIALS AKD JAPAH'S PEACETIME ECOKOMY

1. JAPAN'S ROAD BACK - TO WHAT?

a. Both the Allied Forces and the Japanese government have a
problem vhich complicates every plan and enters every decision. What is
the character of the economy toward which Japeifa should be directed?
Japan is on the road back - but back to what?

2. JAPAN'S FUTURE ECONOMY

a. A partial answer to those questions will be provided at the
peace table, but em accurate final answer depends on still other features
which will be difficult to predict at any tine. Both types of compli-
cating factors are illustrated even in so simple a decision as the
determination of what and how much of a given commodity Japan needs to
"sustain" her economy. Among them may be ment^ionedJ

(1) Possible changes in the rate of population growth and
rural-urban population shifts

(2) The difference between prewar and postwar peacetime
requirements for consumer goods and raw materials

(3) The degree to which Japan's economy will be de-industri-
alized

(4) The economic effects of the geographic dismemberment of
Japan (the lose of Korea, Formosa, Karafuto, and
Manchuria)

(5) The fluctuations of an adjusting economy to postwar
conditions

3. POTSDAM DECLARATION

a. In spite of the unpredictable aspects a rough approximation
of Japan's future economy can be outlined. One of the guide posts in
this respect is the Potsdam Declaration (26 July 1945) , which contains
this paragraph: "Japan shall be permitted to maintain euch industries as
will sustain her economy and allow the just reparations in kind, but not
those which would enable her to rearm for war. To this end, access to,
as distinguished from control of, raw materials shall be permitted. The
eventual Japanese participation in world trade relations should be per-
mitted".

b. The declaration, while general in content, clearly points to
the fact that despite the limitations to be put on Japan's economy, it
will be permitted to recover from its present low level. To do otherwise
would be to condemn millions of Japanese to a below subaistenca level, if
not out-and-out starvation. When Japan's economy was purely agricultural,
it supported a rather stable population of about thirty cillion people;
the addition of forty million in less than a century has been made possible
mainly by the growth of industry and foreign trade.

4. STUDIES Oy JAPAN'S FAST FHODUCTIOH AKD THADE

a. In order to impart more specific meaning to the general
principles laid down by the Potsdam Declaration, perhaps the moat useful
approach is the study of Japan's prewar basic economic features. This
method may serve as a useful reference to the basic question under con-
sideration: What is the economy toward which Japan should be directed?

b. One method of analyzing Japan's economy is by means of the
"pie-rcharts" reproduced here (See Plates 15 - 17). These are designed

as illustrations for economic studies, each one representing a particular
condition in the early 1930 's. These studies do not offer definitive
answers to problems facing the Allied Powers in shaping Japan's postwar
economy, but they are e«BentialB in formulating the answers.

c. Figure 1 (Plate. 15) describes the material composition of
Japanese national wealth and Figure 2, the occupation of her people in
1930. These comparisons are basic to an understanding of Japan's past
economic attainments as well as its future aspirations.

d. Figures 3 and 4 (Plate 15) show the relative position of
Japan in the world picture of the two most important food crops, rice and
wheat. It is safe to assume that Japan's respective shares in world
totals are not likely to change much in the immediate future; however,
the output of these crops in Japan is likely to be larger than in the
prewar years. Japan will not be in a position to import as much food as
was the case in the past; she will have to rely upon a larger domestic
production for a still greater share of food consumption.

e. Industrial crops are illustrated in Figure 1, Plate 16 (tea)
and Figure 2, Plate 16 (raw silk). Japan produced an average of about
50,000'metric tons uf tea from 1930 to 1935 and 42,000 metric tons of raw
silk. It should be emphasized, however, that the data on silk represents
em optimum never to be attained again. In 1929 about two-fifths of
Japan's exports consisted of raw silk. This trade was unique in that It
did not depend on imported raw materials; but silk exports had greatly
diminished by 1937, and they probably will not regain their former '
position in view of the competition from synthetic fibres.

f . Sinilar attention may be given to other commoditieB shown on
Plates 16 and 17 for the purpose of determining Japan's place in world
economy as a producer of certain basic commodities.

g. Another fruitful approach to Japan's future economy is
through study of its foreign trade, the country's very life-blood in tha
past fifty years. For reasons peculiar to Japanese economic and political
development, the domestic market for manufactured goods has been modest

at best. Japan concentrated her efforts, and successfully so, on foreign
markets. Within three decades (1911-1939) foreign trade increased six-
fold and trade with colonial possessions more than twenty-fold. This in
turn shaped the type and size of Japan's industrial fabric.

h. What are Japan's foreign trade prospects now? In this regard
one must mention Japan's loss of Korea, Formosa, Manchuria, Southern
Sakhalin, South Sea Mandated territories, and its former privileges in
Manchuria and China. This colonial trade, which was conducted in circum-
stances favorable to Japan, will now become foreign trade. Even if
allowed to buy and sell on equal terms with other nations in her former
colonial territories, Japan, will no longer be able to mold the economy of
those territories to its special advantage. The net effect will be still
greater dependence upon foreign trade to pay for industrial raw materials
and imported foodstuffs.

i. What are likely to be the responses of Japan's economy to
these foreign trade prospects? Japan will doubtless attempt to reduce
her food imports to a minimum by devoting more manpower to agricilture
and fishing than before the war. In reality, hov/ever, the return from
application of additional labor in these fields will be small. It seoas
probable then that the only solution left to her will be that of retracing
part of the course followed in the two decades before the war, that of
concentrating resources on consumer-goods industry. An accompanying
effort woiild be the revival of export trade in those goods sufficient for
the purchase of needed raw materials and food. But to 'succeed in that
attempt Japan would have to create an export of these commodities far
greater than she had before the war, for her population has grown and
other sources of income (from colonial and foreign investments and
merchant marine) will no longer be available.

j. Japan will be faced with most serious obstacles in her
efforts to revert to the former industrial structure, partly because raw
silk has lost its former pre-eminent- position in international trade, and
partly because of the fear of Japanese competition on the part of Western
industries. The most that now appears likely is a modest participation
in international trade, and rehabilitation a.long similar lines in tra-
ditional manufacturing industries. That much was guaranteed by the
Allied Powers when they made it clear in the Potsdam Declaration that
they would allow Japan eventually to participate in international trade.
The United States repeated this in thp "U.S. Initial Post-Surrender Policy

for Japan", of 22 September 1945, which reads: "Japan shall be permitted
eventually to resome normal trade relationa with the rest of the world
diirii^ occupation and under suitable controls. Japan will be permitted
to purchase from foreign countries raw materials and other goods that it
may need for peaceful purposes, and to export goods to pay for approved
imports."

- 5. CONCLUSIONS ON REHABILITATION

a. Japan, in the forseeable future, may reasonably look forward
to no more than a partial revival of its former manufactural exports.
Because of reduced exports, the loss of colonies, and the loss of shipping
and foreign investments, raw materials imports are likely to be less than
they were in prewar years. Because the population has increased since 1939,
raw material imports may be considerably less per capita than before.
While Japan should be mindful of all possibilities for increasing manu-
factural exports by developing new and superior products, Japanese states-
men, scientists, and business men will nave to examine additional possi-
bilities for improvements in the lot of their countrymen". Possibilities
will include, among others:

(1) Development of higher yielding staple crops

(2) Substitution of domestically produced raw materials for
imported, wherever practical

(3) Elimination of raw material waste in manufacturing

(4) Careful attention to conservation of resources /

(5) Attention to synthetically produced, as constrasted with
nsiturally produced, materials

(6) Examination of the means for reducing the rate of popu-
lation growth

b. Among all that is indistinct in Japan's future, one thing is
clear: the achievement of any substantial improvement in the Japanese
standard of living will come only from many-sided effort. Japan has had
two periods in its recent history, one in which it looked exclusively
inward, and the other in which it looked primarily outward. Now it must
do both, but hopes will best be placed on technical improvement and adap-
tation to the limitations of the resources on its islands. For Japan,
more than at any time since Commodore Perry's visit, will have to live at
home. Occupational policy may be planned on that constant, at, least, and
it should recognize that Japan's future lies in cultivation of physical
science, social science, and the arts of engineering and planning.

SELllCTED RErEHENCES

1. PRELIMINARY STAT^ENT

a. Several thouaand publications deal with the various fields of
the natural resources of Japan. Most of these are technical in scope;
others are generalized and inaccurate; still others include lengthy bihli-
ographies. The references with recorded titles constitute a sample of the
unclassified literature available in the library of the Natural Resources
Section, Mitsubishi Shoji Building. Room 504. Many classified publi-
cations are available to authorized personnel. The library number pre-
faced by the initials "KRS" is given for each reference.

b. An exceptionally good library is the Economic Research
Council Library, formerly the Mitsubishi Research Library. It contains
60,000 volumes, 20,000 of which are in languages other than Japanese. It
also contains a wide variety of perlodicalp of recent years. Booka and
publications may be used in the reading room of the library. A complete
card catalogue index is available to library users. Th? reference for
publications in this library is ERG.

d. Copies of the "Catalogue of Publications in the Natural Re-
sources Section Library" are available on request to authorized personnel.
