141 May 6, 198 1 JAPANESE DEFENSE POLICY INTRODUCTION During the
late 1940s, the United States, responding to a variety of pressures
occasioned by the Sovietization of Eastern Europe and the Comqunist
takeover in China, came to desire Japan more as a stable friend
than a s a defeated enemy most important manifestations of this new
American policy..was an intensification of efforts from 1947 on to
secure and negotiate a peace treaty with Japan was finally signed
in San Francisco in 1951, a'bilateral security pact was simul t
aneously entered into between the United States and Japan One of

years since that original Security Since that time .Japanese
defense policy Treaty was initialed has been formulated on the a s
sumption that the Soviet Union posed the principal potential
threat, both externally and domestically to the security of Japan
and that a continuing defense relation ship with the United
States'was not only beneficial, but essential past thirty years
have been reflected in the original Security Treaty of 1951, a
subsequent revision The Treaty.of Mutual Cooperation and Security
in 1960, and the reaffirmation of the latter in 1970 first appeared
in the form of a document labeled Basic Policies For National D
efense issued by a newly formed Japanese Government Defense Council
in May 19

years through a series of defense plans and programs offered by the
Self-Defense Agency four basic principles of defense enunciated by
the Defense Council over two decades.ago continue to guide modern

UNITED STATES In the aftermath of Japan's defeat and surrender in
1945 the ultimate objective of the Allied Occupa t ion forces
stationed in Japan was to foster those conditions which would
ensure that Japan would not again become a "menace to.the peace and
security of the world.If1 accordance with the Potsdam Declaration
of July 26, 1945, were Ifthe abolition of milita r ism and
ultra-nationalism in all their forms; the strengthening of
democratic tendencies and processes in governmental, economic and
social institutions; the encourage ment and support of liberal
political tendencies in Japan; and the .disarmament and dem
ilitarization of Japan, with continuing control over Japan's
capacity to make warVf (emphasis added This later point was
institutionalized in the Post-War Constitution promulgated on
November 3, 1946 and put into effect on May 3 19

forth and enacted, in Cf. Daraf2raDh 3a of the United States Joint

justice and order, the Japanese people forever renounce war as a
sovereign right of the nation and the threat or use of force as

The right of belligerency of the state will not be recognized.3

in Washington, especially during the late 1940s and early 1950s,
about ''Russian expansive tenden cies,It5 the Communist takeover in
China, the outbreak of the Korean War and their collective impact
on Japan's external s ecur ity.
On September 8, 1951, concurrent with the signing of the Peace
Treaty in San Francisco which restored Japan as an independent and
sovereign nation, a security arrangment was initialed guaranteeing
Japan's external security. This bilateral securit y pact between
Japan and the United States provided for the continuation of U.S.
military forces and installations in Japan, the use of such forces
to help maintain peace and security in the Far East, and the
deployment of American military personnel and e quipment to quell
domestic revolts should Japan request such assistance. Although
there was no explicit statement in the treaty which obligated the
United States to defend Japan, the presence of American forces and
bases most certainly served to deter an armed attack on Japan from
without hardly surprising that the Japanese reaction to such an
agreement was not one of unqualified acceptance and
appreciation.
Japanese sense of nationalism was offended by the presence of
foreign troops and bases. There was a lso dissatisfaction and
controversy with those arrangements in the treaty providing for the
use of Japanese-based American troops to suppress domestic
rebellions, jurisdiction of American personnel involved in crimes
against Japanese citizens and property , and the possible storing
and use of nuclear weapons by American forces stationed in
Japan.
These dissatisfactions eventually resulted in protracted negotia
tions between the two countries looking forward to a more equitable
revision of the 1951 treaty As this treaty contained some
llunequallt aspects it is The U.S. Department of State, Publication

Such a dramatic l1atmospherici1 change was attributable, in

ruling Liberal Democratic Party (LDP ing the administration of
Prime Mi nister Nobusuke Kishi (the negotiator of the 1960 treaty),
the LDP platform had among its stated goals the twin pillars of
constitutional revision and rearmament. Following Kishi's abrupt
resignation, Prime Minister Hayato Ikeda and his followers in the L

Because of the massive demonstrations against the Kishi
government President Eisenhower was forced to cancel his goodwill

Minister Kishi resigned.

goal of expanding trade and manufacturing. The policy of
growthmanship combined with Ilpolitical low posture may have been
forced on the LDP government at its inception, but it was also a de
l iberate policy pursued with skill and energy. The architects of
Ikeda's policy justified small defense outlays as a booster of
econymic growth, and the defense.budget was allowed to decline from
1.2 percent to 0.8 percent of the GNP during the 1960s. Succ e
ssive LDP governments, in their dealings with Washington, began to
point to the sensiti vity of the left on matters of defense in
order to stave off U.S. pressures. The United States, for its part,
learned not to rock the boat 10 During the 1960s, Japan p u rsued a
somewhat paradoxical approach to defense issues: pacifism and
protectionism. Symbolic of the LDP-leftist collaboration in pursuit
of pacifism were the policies of the Three Principles of Nuclear

assurance of American protection against threats to its security.

The joint communique is important for a number of other reasons.
Both parties reaffirmed their desire to continue the Mutual

Japan, for the first time, officially recognize d that their
security was intimately tied to the peace and security of the Far

posture throughout the worl d , while at the same time maintaining
our commitments, i.e., the mutual security treaties with our

allies, including Japan, with doubt developing into shocks and
suspicions, especially after the February 1972 U.S.-PRC meeting and
its accompanying Shanghai communique. Tokyo, for one, was not
informed by Washington in advance of Secretary of State Henry
Kissinger's visit to Peking though a pledge had been given
privately to the Japanese government a few years earlier that it
would be notified in advance of any major change in American China

a Cabinet meeting of the government of Takeo Miki defense capab i

peacetime, a balanced defense posture with effective organizations
and functional positioning of units and equipment which are capable
of coping effectively with aggression ranging from conv entional
warfare with smaller scale than limited wars to aggression of more
smaller scale with limited geographical expansion, objectives,
means and duration."
One of the assumptions underlining the Outline was the notion
that international geopolitical de velopments often involve factors
of uncertainty and unpredictability e.g., the Nixon Doctrine Two
years later, in November 1978, the U.S.-Japan Security Consultative
Committee approved a counterpart to the Outline, namely the

cooperation between Japanese Self-Defense Forces and U.S. forces in
such areas as operations, intelligence and logistics.18 Since the
1950s, popular attitudes toward defense issues in Japan have on the
whole been emotional and n egative. During the past several years,
however, Japanese attitudes toward defense problems have undergone
a gradual but significant evolution.
Growing public awareness of defense issues and acceptance of the
Self-Defense Forces and the Mutual Security Tre aty do not mean
that attitudes about the role and missions of these forces have
changed is still subject to post-war constitutional restraints and
remains today a very serious political problem The Outline did not
simply estimate quantities of These Guide l ines endeavor to
achieve a posture for Japanese willingness to assume increased
responsibility JAPANESE SELF-DEFENSE FORCES Article IX of Japan's
Constitution is truly a monumental landmark in the annals of
international law. No other nation in history, l e t alone a major
power such as Japan has gone so far as to renounce war as a
sovereign right, while denying itself the maintenance of armed
forces or the threat of force as a means of settling international
disputes. As straightforward as Article IX appear s to be, there
have been a multiplicity of interpretations which have beseiged the
Article since its implementation. However no objection is raised by
the Constitution to the right of Japan as an independent nation to
defend itself from any foreign invasio n in December 1959, stated
that pacifism as defined under the Constitution does not stipulate
non-defense or non-resistance on the part of Japan. Indeed, the
preamble of the Constitution The Japanese Supreme Court, in a
ruling on the Sunagawa Case l8 In ad d ition to the above, the
Guidelines specify actions to be taken in response.to an armed
attack against Japan. 8 specifically states that "the people of the
world have the right to live in peace, free from fear and want From
this perspective it is "not just i fiable to consider the
Constitution as prohibiting the maintenance by Japan of the minimum
required level of prepared ness against situations in which the
'people's life, liberty and pursuit of happiness' as guaranteed by
the Constitution are seriously en dangered.I1lg held the view that
Japan's national defense capabilities must be exclusively for
self-defense, and that any action exceeding this limit is strictly
prohibited, constituting as it would the creation of a "war
potential.
It was not until the ou tbreak of the Korean War in 1950 that a
basic structure for Japan's Self-Defense Forces began to be
devised. Upon instructions from General Douglas MacArthur, a
75,000-man National Police Reserve Force was established to "deal
with international disorders Following the signing of the San
Francisco Peace Treaty and the Japan-United States Security Treaty
in 1951, lively debate ensued within the Japanese Diet over the
establishment of defense guidelines and a gradual buildup of
defense capability as proposed by the Liberal Party (Jiyuto in the
fall of 1951 In April 1952, a Maritime Safety Force later renamed
the Coastal Safety Force, was established to deal with maritime
security. In August of the same year, a Safety Agency was formed to
administer the nascen t military forces Police and Coastal Finally,
on October 15, 1952, the Security Agency (Hoancho) was established

of the Japanese Diet (May and June 1954), a new security agency,
the Defense Agency (Boeicho), was formally established on July 1

advisory body, was created with responsibility for formulating

Ilconstruct a fundamental ground defense capability- in order to
cope with the rapid reductions in U.S. ground forces s t ationed in
Japan.1121 The plan also aimed at establishing maritime and air
defense capabilities. During this period, Japan anticipated leasing
some ships, aircraft and substantial equipment from the United
States. The plan also called for recruitment of 1 8 0,000 ground
force personnel, construction of about 124,000 tons of shipping and
acquisiti0.n of about 1,300 aircraft thening that defense potential

scale no greater than local ized 'confl i ct.1t22 Especially
important here was the call for qualitative improvements in the
basic defense capability in light of the development of scientific
technology. goals of this Plan were the programmed replacement of
obsolete equipment, the introduction of ground-to-air missiles, and
the institution of an ongoing R&D program The Second Defense
Buildup Plan (FY 1962-66 aimed at streng Among the major The Third
Defense Buildup Plan (FY 1967-71) was aimed at consolidating the
defense potential of each of the v arious services.
However, special emphasis was placed on strengthening maritime
defense capability within Japanese coastal waters and ai,r defense
capability in key areas.
The Fourth Defense Buildup Plan (FY 1972-76) was essentially a
follow-up program of the previous plan was placed on the
modernization and replacement of outmoded equipment, improvements
in maritime and air defense capability and specific increases in
the various armed forces levels. Some of the goals of the Fourth
Plan were unattainable , particul'arly arms acquisition, due in
large measure to the economic situation resulting from the oil
crisis. In the period that followed the defense budget was not
substantially increased and was limited to, what Professor Kataoka
calls, Mikits canonize d Ill percent of GIGi1 uncrossable barrier
Once again emphasis Given the fact that a Fifth Buildup Plan was
economically untenable and politically unfeasible due to the
mounting pacifist opposition to enlarging the SDF, the Miki
government espoused a new p rogram which, in their minds, could
provide for external defense and satisfy pacifist opposition.
In October of 1976, the Japanese government abandoned the
various Buildup Plans, opting instead for a "National Defense

providing, even in peacetime, a balanced defense posture capable of
coping effectively with situation s up to the point of limited and
small scale aggression rather than maintaining a defensive force
capable of surviving a full-scale conventional war as had been
previously emphasized in earlier government plans. Whereas previous
defense plans have been spe c ifically detailed (see accompanying

Outline further states that if greater than a "limited and
small-scale aggressionll is encountered, the standard defense force
should be capable Itof continuing effective resistance until such
time as cooperation with the United States can be introduced thus
rebuffing such aggression.
In essence, the Outline aimed at a qualitative, rather than
quantitative improvement in Japan's defense posture, emphasizing
impro vements in logistical infrastructure, maritime surveillance
and air defense. The Defense Agency, having lowered their sights to
attainable goals, was now able to lay down for the first time
rather specific,levels of arms maintenance, replacement schedules
and accompanying budgets It remains to to be seen, however whether
such qualitative changes have significantly improved the
capabilities of the Self-Defense Forces, and whether these changes
are sufficient to meet the changing military balance in the Far
East THE CHANGING MILITARY BALANCE IN THE PACIFIC Contemporary
Japanese defense planning remains rooted in the Standard Defense
Force Concept enunciated in 19
76. Essential to an understanding of this program, particularly
its emphasis on repelling only lim.ited, small-scale aggression, is
its..evaluation of the domestic and international situation at the
time. This perspective assumed that no major changes wer e
anticipated in the domestic and international situation in the
foreseeable. future,26 and that any aggression requiring advance
preparation would allow time for the arrival, deployment and use of
adequate U.S. forces.
While such assumptions may have been valid in 1976, developments
over the past five years call into question the continuing legiti
macy of such premises.
The most significant change in the past five years has been the
continued and unrelenting buildup of Soviet conventional and
nuclear mili tary power and the increasing interference, through
surrogates such as the Cubans, in the internal affairs of other
nations (e.g., Angola, Ethiopia, Cambodia and Afghanistan The
dimension of the Soviet military buildup is particularly revealing
when one e x amines overall Soviet defense spending: For each of
the past twenty years, Soviet defense spending has in creased
steadily and significantly by an average of 4-5 percent a year.
According to CIA estimates, the Soviets allocate 12-14 percent of
their GNP t o defense, whereas the United States spends only about
5 percent. The discrepancy is all the more remarkable 25. 26 9 Ibid

Posture for FY 1982 Supplement, p. 1 27 12 when one considers that
the Soviet GNP only ranges between 50 and 75 percent that of the
United States.. According to former Secre tary of Defense Harold
Brown, the Soviets spent about 50 percent more than the United
States on defense in.1980 (using estimated d ollar costs).28 In
terms of investment efforts (research and development, procurement
and military construction), the statistics are similarly revealing.
Only a decade ago (1970), Soviet invest ments began exceeding those
of the United States; today, Sovi e t investments are 80 percent
greater than those of the U.S over the past decade U.S.
investments'have fallen some 20 percent Soviet investments have
risen 50 percent. From 1968 to 1979 Soviet investments are
estimated to have been $270 billion more than t h ose of the United
States While Throughout the past decade the Soviets with their
commitment of massive resources have continued to strengthen and
modernize their armed forces in all categories. As to their
strategic offensive forces, the Soviets have now completed
deployment of their fourth generation of intercontinental ballistic
missiles including the SS-17, SS-18 and SS-

totaling-81,450 tons raising its total strength to 785 vessels, or
1,520,000 tons.30 Among these additions were: the Minsk, the second
of the Kiev class aircraft carriers (32,000 tons); the
Petropavlovsk, the fifth Kara-class missile-c a rrying cruiser
(8,200 tons); the Ivan Rogov, the first of the new amphibious
assault transport/dock ships (11,000 tons); a Ropucha-class landing
vessel (3,450 tons a Dubna-class supply ship (12,000 tons); the
Tashkent, a Kara-class missile cruiser (8,200 t ons); and two
missile destroyers of the Krivak I and II-class (each 3,300
tons).31 The Fleet itself has a total of 507 combat ships,
comprising 110 submarines32 (including 30 carrying strategic
missiles); one ASW aircraft carrier 78 cruisers, destroyers, . and
frigates; and 318 amphibious ships and boats, patrol boats and mine
warfare ships. Of the Fleet's 169 attack submarines, ASW aircraft
carrier cruisers, destroyers and frigates, approximately one-fourth
are equipped with missiles carrying nuclear or co n ventional
warheads capable of attacking surface ships and submarines. The
Fleet flag is at Vladivostok, with most of the surface combatant
ships as well as half of the submarine fleet, attached to the
southern segment of the Fleet stationed in the Sea of J apan.33
segment of the Fleet, primarily stationed at Petropavlovsk on the
Kamchatka Peninsula, is heavily weighted with submarines See map of

Capabilities'for attacking ground aircraft. These include about 450
bombers, 1,450 fighters, and about 160'patrol planes targets and
ships have been enhanced, as has their stand-off attack
capability.
In terms of theater nuclear forces, the Sovi ets have now
deployed the TU-22M BACKFIRE bomber, a small number of which are
stationed around Irkutsk, and the SS-20, deployed east of Lake
Baikal. The SS-20 is a mobile, solid-fuel-propelled IRBM with three
150-KT nuclear MIRVed missiles with a range ca pability of some
5,000 km. These missiles and bombers are capable of reaching almost
any part of.Asia, including Taiwan, Korea, China and Japan.
Of particular significance to Japan has been the increased
Soviet presence on the Northern Islands (see map insertion) about

Immediately after the end of World War 11, the Soviets invaded the
northern islands and stationed a corp of troops and RIG-17 fighters
on the island of Kunashiri and Etorofu. Such a military presence
was to remain until the summer of 1960 when Khrushchev announced a
decision to cut Soviet armed forces by 1.2 million men.
However, the Soviets began reintroducing ground troops and
creating military installations on the two islands from around May
19
78. Since the summer of 1979, they have extended their
operations to the island of Shikotan (which never had been occu
pied approaches the size of a division circa 6000 men. Divisional
headquarters is on the island of Etorofu with tanks, surface-to-air
mi s siles, and other weapons of a motor rifle division, as well as
with large-caliber 130 mm guns. Armed helicopters with anti-tank
missiles have recently been sighted 12 MIG-24s The Air Defense
Force comprises approximately 24 In contrast to the slow but ste a
dy upgrading of Soviet The combined total of Soviet forces on these
islands The troops are equipped MIG-~~s forces in the Far East is
the somewhat static position of U.S forces. U.S. troop'strength in
the Pacific has shrunk from a level of 250,000 in 1964 , the
baseline year before the Vietnam buildup, to some 130,000 today.
U..S. force levels currently are at their lowest in three decades.
The only readily available major maneuverable.force west of Hawaii
are the 2nd Infantry Division in Korea and the 3rd Marine Division
on Okinawa.
Correspondingly, only seven amphibious ships are assigned to the
Pacific Fleet four of which were assigned to the Arabian Sea during
part of the Iranian Crisis. In mid-1964, the U.S. had 15 Air Force
fighter squadrons; today, th eir number has been reduced to five.
While the Pacific Fleet, composed of the 7th and 3rd Fleets, had 11
carriers in 1964 (both CVA and ASW), today there are only six
(CVA/N Though four were formerly deployed with the Seventh Fleet,
only two are still per m anently attached.35 Though a rough state
of equilibrium exists today between the U.S. and the Soviet Union
in the Far East, the future forecast is far less certain. In his
farewell address as Commander-in-Chief for the Pacific (October 31,
1979, Hawaii), Admiral Maurice F.
Weisner poignantly observed "that Soviet momentum in
conventional military force improvements will put us in second
place especi ally here in the Pacific where we are no longer in a
position of military superiority and where military par ity is
threatened 34 AsianSecurity- pp. 42-45 35 Cf. John M. Collins,
U.S.-Soviet Military Balance: Concepts and Capabili ties 1960-1980,
p. 348. 16 Further complicating the overall Pacific environment is
the threat posed by North Korea. In 1979, the U.S. intelligence
community admitted that its estimates of the North Korean armed
forces were too low. North Korean ground forces were reappraised
upwards by 25 percent to 600,000 men; the number of divisions by 40
percent to 37; and tanks by over 33 percent t o 2,6
00. North Korea today possesses the world's fifth largest army
and the sixth largest submarine force.
In contrast, the South Korean armed forces are seriously
outnumbered. Though their ground forces are roughly equivalent the
North Koreans hold a de cided 3:l edge in aircraft, a 2.5:l edge in
tanks, and a 4:l superiority in ships. This unstable military
position is particularly significant given Japan's recognition that
her security is intimately tied to that of Korea.
CURRENT ANALYSIS OF THE SELF-DE FENSE FORCES Given the
ever-increasing threat posed by the Soviet Union and North Korea to
the overall military balance in the Far East it is important to ask
whether current Japanese Self-Defense Force levels are adequate to
meet potential aggressors.
Th e Japanese Self-Defense Force is currently divided into three
separate branches: Ground, Maritime and Air. The Force's primary
responsibility is to stand ready to repel any armed incursion
against the home islands.of Japan therefore, defensive in nature a
n d has been structured according ly. Current force levels in all
branches, however, are inadequate and seriously jeopardize Japan's
ability to defend itself against external aggression. Before
reviewing the current mission status and operational capability of
each branch of the Self Defense Force, including.new equipment
allocations for the coming year, a few words need to be said about
the current defense budget and the overall budgetary process Its
mission-is Current Budget The budgetary process in Japan,
particularly the role of the bureaucracy in formulating fiscal
policy, differs dramatically from that found in the United States
and hence deserves review.
The Finance Ministry (Okurasho) is the primary bureaucratic
organ charged with determining the budg et for all ministries and
agencies in the Japanese government. Performing more than an
advisory function, the Finance Ministry often comes into conflict
with the Diet as well as the leadership of the LDP. Unlike U.S
departments, which take a limited .role in determining government
fiscal policy, the Finance Ministry operates like an autonomous Om;
any major decision must clear the Ministry'before its imple
mentation. 17 In particular, the defense budget has always
generated controversy between the Finance M inistry, the Defense
Agency and the LDP-controlled Diet. The Ministry prefers to fund
domestic programs and has generally taken a dim view of military
and defense-related projects and expenditures. With the decline in
the growth of the Japanese economy, t h e reluctance of the
Ministry to expend funds for the Self-Defense Forces has risen
proportion ately period (announced on April 29, 1981) will further
fuel the Finance Ministry's arguments for fewer defense-related
allocations The decision to hold back aut o imports over a
three-year The Japanese political custom of decision by consensus
requires consultation with the Finance Ministry before implement
ing any fiscal policies. This decision-making process, coupled with
the Finance Ministry's monopoly on econo m ic information necessary
in formulating the budget, assures the continued import ance of the
Ministry in the budgetary process In May of last year, Prime
Minister Ohira agreed in principle to an increase in Japanese
defense spending as a percentage of GNP . Following Ohira's
untimely death, Prime Minister Zenko Suzuki reaffirmed Japan's
commitment to improving national defense through an increase in the
defense budget cant increases in the defense budget would be
impossible, the full Cabinet on July 29 appr o ved a scheme
exempting the defense budget from the overall ceiling placed on
other ministerial budget requests. The defense ceiling was set at a
9.7 percent increase rather than the 7.9 percent for other
agencies. Accord ingly, the Defense Agency requeste d a budget of
Y2,474 billion representing 0.92 percent.of Japan's GNP.
During subsequent negotiations, the Finance Ministry cut defense
appropriations to 6.6 percent. Suzuki, however, was able to achieve
a compromise of a 7.6 percent increase, bringing the approved
budget to Y2,400 billion or approximately $11.8 billion.
This budgetary increase, after adjusting for inflation, amounts
to about a 4 percent increase in real terms only a 0.6 percent rise
over last year's increase I Despite warnings by Finance Ministry
officials that signifi Capabilities and Deficiencies of the
Self-Defense Forces A) Ground Self-Defense Force (GSDF The primary
mission of the GSDF is to prevent foreign nations Given the.
geographic configura- from successfully invading Japan tio n of
Japan, ground forces should be highly mobile, able to be quickly
deployed in a variety of terrains and locations.
Accordingly the GSDF emphasizes armor as the primary, mobile
striking force. Currently, the GSDF has about 830 tanks on line
most of which are the older Type061 model.
Japan's aging tank capability, the new budget calls for 72
Type-74 In order to upgrade 18 tanks to supplement current strength
levels. In addition, the new allocation calls for an additional
nine Type-73 armored personnel ca rriers and 36 203mm and 155mm
self-propelled howitzers in order to "beef up present levels of
mobile, support artillery.
The present personnel quota of the GSDF is 180,000 troops.
However, current manpower is maintained at only 86 percent of
the authorized quota with a ready reserve force of 39,000 buildup
plan announced by Prime Minister Suzuki on April 28, 1981 calls for
the addition of 25,000 troops to the active ground force, t hereby
bringing its strength to the authorized level.
The anti-tank capability of the GSDF lags far behind current
technology found in other ground forces. Japan has yet to deploy an
effective anti-tank missile system and still relies on the 84mm
recoiless rifle which has a relatively short kill range and limited
destructive capability. The Type-79 anti-tank and anti ship missile
launchers are scheduled for deployment this year but production
will leave the GSDF anti-tank capability below desired levels Th e
B) Maritime Self-Defense Force (MSDF The MSDF has a two-fold
mission: to protect the nation against seaborne invasion and to
secure the sea lanes around Japan in the event of war The MSDF
emphasizes anti-submarine warfare. Consequently its ability to def
end against missile and airborne attack at sea is considered
inadequate.
Japan's naval capability, the new budget includes authorizations
for one 4,500 ton destroyer; two 2,900 ton destroyers; one 2,300
ton submarine-killer submarine; two 440 ton minesweep ers; and six
HSS-2B anti-submarine warfare helicopters. In addition, the MSDF
is.currently deploying the P3C and has plans to purchase 'one more
squadron for deployment in late 1982 In an attempt to upgrade and
strengthen In the event of war in the Pacifi c , Japan would be
incapable of mining the strategically important straits which
surround Japan and would be unable to I1choke-offt1 the Soviet Navy
at Vladivostok. The MSDF currently deploys only one minelayer and
has not announced intentions to purchase a nother, though methods
of improving Japan's minelaying capabilities are currently under
consideration.
In an attempt to upgrade transport capabilities, construction
has begun on two 500 ton transport vessels to support the six ships
currently providing mar itime, logistic support to the GSDF C) Air
Self-Defense Force (ASDF The ASDF is organized, equipped and
deployed to engage in defensive operations only strikes against a
potential enemy, the ASDF must be able to react Denied the right to
initiate air quic kly to intercept and destroy airborne invaders
with little prior warning In order to bolster ground radar
capability, the ASDF has decided to purchase two E-2C early warning
aircraft in FY 1982 and two more in FY 19
83. In addition, Japan's ground radar equipment is being
modernized and the current Base Air Defense Ground Environment
(BADGE) system in use since 1967 is being upgraded, with studies
currently underway to determine a suitable replacement.
Japan's main interceptor-fighter, the F-4EJ, has become somewhat
obsolete in view of the more sophisticated aircraft being
introduced in and around the area of Japan by other nations.
Consequently, in 1978, the F-15 was selected to replace it with
the first squadron scheduled for deployment in the latter half of
19
82. Additionally, Japan lacks an adequate electronic warfare
capability, precision-guided bombs and a sophisticated air defense
missile system. The NIKE, operational since 1962, remains Japan's
primary surface-to-air missile defense though plans f or its
replacement. are currently under consideration In order to upgrade
the ASDF, the current budget calls for the purchase of two F-1
supersonic ground support fighters; two U.S.-made C-130H Hercules
transport planes; four E-2C Hawkeye airborne early w a rning
planes; and'two units of short-range SAM system called Tan-SAM D)
Other Capabilities and Deficiencies The system for combined and
joint operations and the command and control structure are
considered deficient., Effective combined and joint operatio ns are
nearly impossible under present circum stances since there is as
yet no established mechanism for crisis management, for a wartime
leadership structure, for joint opera tions of three services, and
for combined Japan4.S. operations.
Similarly, readi ness is at an extremely low level. A mobili
zation system has not yet been established of personnel and
equipment are considered insufficient, a tendency particularly
noted above in the GSDF Peacetime reserves Finally, there is the
problem of sustainabili t y in a wartime situation. Present
stockpiles of munitions, fuel, food and other equipment are
considered low sioned by the growing power of both the Soviet Union
and North Korea, and the present state of Japanese defense efforts,
one can easily conclude t hat the Japanese Self-Defense Forces
leave much to be desired in both quality and quantity.
National Security Study Group, appointed by Prime Minister Ohira
Given the growing military imbalance in the Far East occa A'
similar conclusion was arrived at by the Comprehensive 20 during
the summer of 19
80. In their Report on Comprehensive National Security, the
Group ridiculed the current capabilities of the Self-Defense
Forces, noting that a half of the defense equipment was virtually
useless, arms stockpiles were insufficient and security
effortswere, in general, deplorable.

carrier All P-3J aircraft should be replaced with P-3Cs and all
F-4Js with either F-15 or even the F-

of an amphibious/airborne, force I Long During both the short- and
long-t erm, Japan must seriously re-evaluate much of the philosophy
underlying its current defense posture It is hoped such a
re-examination will lead to the discarding of such meaningless
taboos as the 1 percent ceiling canonized during the Miki
administration. Similarly, one would hope that the prohibitions
against possession of offensive weapons and the sending of
Self-Defense Forces abroad in any contingency would be eliminated.
Consideration should also be given to the abandonment of the three
non-nuclear pr inciples and export controls on defense
equipment.
Japan should be encouraged to define and develop its own concept
of security and act accordingly In such a re-examination and
re-evaluation William L. Scully Policy Analyst Guy M. Hicks Policy
