The U.S. Military Presence in Okinawa and the Futenma Base Controversy

Summary
Although the U.S.-Japan alliance is often labeled as “the cornerstone” of security in the Asia
Pacific region, local concerns about the U.S. military presence on the Japanese island of Okinawa
have challenged the management of the alliance for decades. The Japanese archipelago serves as
the most significant forward-operating platform for the U.S. military in the region; approximately
38,000 military personnel, 43,000 dependents, and 5,000 DOD civilian employees live in Japan.
With the United States pledging to rebalance its defense posture towards Asia, the uncertainty
surrounding the medium and long-term presence of American forces on Okinawa remains a
critical concern for national security decision-makers.
Due to the legacy of the U.S. occupation and the island’s key strategic location, Okinawa hosts a
disproportionate share of the continuing U.S. military presence. About 25% of all facilities used
by U.S. Forces Japan and about half of the U.S. military personnel are located in the prefecture,
which comprises less than 1% of Japan’s total land area. Many observers assert that Tokyo has
failed to communicate effectively to Okinawans the necessity and benefits of the alliance.
However, Okinawa has received millions of dollars in subsidies from the central government in
exchange for the burden of hosting U.S. troops. This year, Tokyo awarded a large amount to
Okinawa for the prefecture’s economic development plan.
In 2006, as part of a broad realignment of U.S. basing in Japan, the United States and Japan
agreed to relocate Marine Corps Air Station (MCAS) Futenma to a less-congested area on
Okinawa, a move that would have triggered the redeployment of 8,000 Marines to U.S. bases in
Guam. The arrangement was designed to reduce the local community’s burden of hosting a loud
air base that has generated safety concerns and, eventually, to return control of the Futenma land
to local authorities as a way to boost economic development in the area. The controversy
surrounding relocation of MCAS Futenma has overshadowed progress in the largely successful
implementation of other elements of the realignment agreement.
Implementation of the Futenma relocation plan has stalled, due largely to political turmoil in
Tokyo and resistance in Okinawa. Former Prime Minister Yukio Hatoyama had made a campaign
pledge to close Futenma and transfer its functions off Okinawa, a position he maintained in office
until reversing himself in May 2010. Since then, his successors also have endorsed the plan, but
the opposition in Okinawa has hardened, and all the major political figures involved in approving
the new base construction have publicly opposed the plan.
In addition, the U.S. Congress has raised major concerns about the ballooning costs of moving the
Marines to Guam and blocked funds dedicated to the realignment in military construction
legislation. The initial estimate was for an expense of $10.3 billion to move 8,000 marines and
their dependents to Guam, but the GAO reported that the actual costs would be more than double
the DOD estimate at $23.9 billion. Senators Carl Levin, John McCain, and James Webb have led
the scrutiny of the existing plan and continue to question its affordability and practicality, along
with other elements of the U.S. defense posture in the Asia-Pacific.
After six years of paralysis, the United States and Japan officially adjusted the policy in April
2012 by “de-linking” the transfer of marines with progress on the Futenma Replacement Facility
(FRF). Although both capitals remain officially committed to the construction of the new base,
numerous political and budgetary obstacles remain that make progress in the near term highly
unlikely. The Futenma base remains in operation, raising fears that an accident similar to a

helicopter crash in 2004 might inflame Okinawan opposition. The U.S. military plans to deploy
MV-22 Osprey tiltrotor transport aircraft to Futenma as early as fall 2012, a move expected to
draw local protests because of safety concerns. Meanwhile, unstable political leadership in Tokyo
further threatens the chance of implementation. On the U.S. side, defense officials have not fully
alleviated congressional concerns about the funding requirements and feasibility of the plan.
This report will be updated as circumstances warrant.

The U.S. Military Presence in Okinawa and the Futenma Base Controversy

Overview
Despite the prominence of the U.S.-Japan alliance in America’s overall strategic posture in the
Asia-Pacific region, local concerns about the U.S. military presence on Okinawa have challenged
the management of the alliance for decades. In recent years, Okinawan resistance has crystallized
around the relocation of a U.S. Marine Corps Air Station. The Japanese islands serve as the most
significant forward-operating platform for the U.S. military in the region. With the United States
pledging to rebalance its defense posture towards Asia, the uncertainty surrounding the medium
and long-term presence of American forces on Okinawa remains a critical concern for national
security decision-makers. Many regional analysts have posed the question of whether this issue is
at its core simply a real estate dispute, or if the controversy threatens the fundamental
sustainability of the alliance.
The relocation of Marine Corps Air Station Futenma (MCAS Futenma) is the largest and most
problematic part of a broad overhaul of the stationing of U.S. forces in Japan and changes in how
the Japanese and American militaries operate. A 2006 agreement between the U.S. and Japanese
governments to relocate the Futenma base from its current location in the crowded city of
Ginowan to Camp Schwab in Henoko, a less congested part of the island, was envisioned as the
centerpiece of a planned realignment of U.S. forces in Japan. The proposed air station is often
referred to as the Futenma Replacement Facility (FRF). The arrangement was designed to reduce
the local community’s burden of hosting a loud air base that has generated safety concerns and,
eventually, to return control of the Futenma land to local authorities as a way to boost economic
development in the area. In addition, the relocation would have triggered the transfer of roughly
8,000 marines and their dependents from Japan to new facilities in Guam. Japan agreed to pay
around 60% of the $10.3 billion estimated costs.
The agreement was struck at a moment when the bilateral relationship was seen as at its strongest
point in decades, but implementation has been a struggle, due largely to political turmoil in Tokyo
and resistance in Okinawa. In the watershed August 2009 parliamentary elections, the Democratic
Party of Japan (DPJ) defeated the Liberal Democratic Party (LDP), which had held power nearly
continuously since the mid-1950s. Incoming DPJ Prime Minister Yukio Hatoyama had pledged in
his campaign to close MCAS Futenma and remove its functions from Okinawa, a position he
maintained in office until reversing himself in May 2010. Since then, his DPJ successors also
have endorsed the 2006 plan, but the opposition in Okinawa has hardened. In addition, the U.S.
Congress has raised major concerns about the ballooning costs of moving the marines to Guam
and blocked funds dedicated to the realignment in military construction legislation.
Essentially conceding that the existing agreement appeared unlikely to move forward, the United
States and Japan officially adjusted the policy in April 2012 by “de-linking” the transfer of
marines to Guam with progress on the new base in the Henoko village area of Nago City. The
announcement also stipulated that arrangements to return some land used by U.S. forces would
not be contingent on the base relocation. In order to ease the burden on Okinawan residents, about
9,000 U.S. marines would be transferred to locations outside of Japan: 4,700 marines to Guam,
1,800 to Hawaii, and 2,500 on a rotational basis to Australia. Alliance officials packaged the
move as in line with their goal of making U.S. force posture in Asia “more geographically
distributed, operationally resilient, and politically sustainable.” Although both capitals remain
officially committed to the construction of a new aviation facility at Camp Schwab, numerous
political and budgetary obstacles remain that make progress in the near term highly unlikely.

August 2012 Status: Logjam on Agreement Endures
At the time of this report, the base relocation agreement appears to be at an impasse, with several
outstanding issues on both the U.S. and Japanese sides. Okinawan authorities seem no closer to
granting authority to begin construction in Henoko as anti-base activists organize protests against
upcoming deployments of the MV-22 Osprey aircraft to Futenma. On the U.S. side, restrictions
on funding remain in place as the Department of Defense (DOD) fulfills legislative requirements
imposed by Congress. On the other hand, officials from both nations have succeeded in removing
Futenma as the all-consuming problem on the bilateral agenda, re-asserted the strength and
commitment of the security relationship, and moved forward with several other important
initiatives. The policy adjustment in April 2012 may provide some political “space” on Okinawa
and in Tokyo to overcome resistance, while DOD officials and congressional Members try to
resolve funding and strategic planning concerns. Meanwhile, some regional analysts fret that
without forward movement on a key security agreement, the credibility of the alliance will suffer.
Okinawa’s Strategic Importance
Okinawa’s key strategic location has become more important over the past few decades. (See
Figure 1.) In the post-World War II environment, Japan’s northern islands were seen as a bulwark
to contain the Soviet Union’s Pacific fleet. Post-Cold War security threats include the potential
flashpoints of the Korean Peninsula and the Taiwan Strait, while more recent assertiveness by the
Chinese People’s Liberation Army Navy (PLAN) in the South China Sea and East China Sea has
drawn growing attention from Defense Department planners. The U.S. military presence in Japan,
and particularly Okinawa, allows it to fulfill its obligations under the 1960 Treaty of Mutual
Cooperation and Security to not only defend Japan but to maintain security in the Asia-Pacific
region. The forward-deployed presence of the U.S. Air Force and Navy also allows for response
to humanitarian disasters in the region, as demonstrated by the massive response to the March
2011 earthquake and tsunami in northeastern Japan.1
Although most strategists agree on the importance of Okinawa’s location for U.S. security
interests in East Asia, there is less consensus on the particular number of marines necessary to
maintain stability. For example, two prominent analysts suggested a rethinking of U.S. military
basing in light of cuts to the U.S. defense budget and Okinawan obstacles; they argue that leaving
a force of 5,000-10,000 marines on Okinawa while also pre-positioning supply vessels in
Japanese waters and bringing most of the marines home to California would amply serve U.S.
rapid response and deterrence needs.2 Defense officials continue to assert the need for substantial
numbers of U.S. marines to be positioned in Asia, but have offered a degree of flexibility in their
exact location; recent plans would deploy marines on a rotational basis through Guam and
Australia. Congressional concerns, as discussed below, have focused on cost and implementation,
but have not argued that the Marine presence itself is unnecessary.

Background: Okinawan History and Grievances
The attitudes of native Okinawans toward U.S. military bases are generally characterized as
negative, reflecting a tumultuous history and complex relationships with “mainland” Japan and
with the United States. Okinawans are ethnically distinct from most Japanese, which may
heighten a sense of discrimination. The Ryukyu island chain, once a semi-autonomous kingdom
ruled from Okinawa, was first officially incorporated into the Japanese state around the time of
the Meiji Restoration in the late 19th Century. These southern islands were largely neglected by
the Japanese central government until World War II, when they became bloody battlegrounds in
the final stages of the “island-hopping” campaign waged by the U.S. military. The Battle of
Okinawa from early April through mid-June 1945 resulted in the deaths of up to 100,000
Japanese soldiers and 40,000-100,000 civilians, many of whom were forced to commit mass
suicide by the Imperial Japanese Army.3 A total of 12,281 Americans were killed, the highest total

of any battle in the Pacific campaign.4 Many Okinawans remember this battle as a dark episode in
a long history of the Japanese central government sacrificing Okinawa for the good of the
mainland.
The United States maintained possession of the Ryukyu islands in the peace settlement ending
World War II. The U.S. military appropriated existing Japanese military bases on Okinawa and
built several more large bases on the strategically located island. The United States paid locals for
the acquired land, but in some cases this purchase reportedly involved deception or outright
coercion, using bulldozers and bayonets to evict unwilling residents. During the period of
American sovereignty, Okinawans had no political authority or legal redress for crimes
committed by service members—though the worst crimes were prosecuted through court martial.
The Korean War and Vietnam War eras brought an influx of thousands of additional U.S. soldiers
and added grievances to local residents, along with a major increase in revenue for businesses
catering to GIs.5
After the reversion of Okinawa to Japanese sovereignty in 1972, the pattern of crimes by
American service members abated, but was nevertheless a major concern for the local population.
The Japanese central government took measures to placate Okinawans, for example by increasing
the rent paid to owners of land on U.S. military bases and by prosecuting eligible crimes in
Japanese courts. Despite these steps and increased funds for prefectural development, many
Okinawans continue to perceive themselves as the victims of policies drafted in Tokyo and
Washington with little regard for their communities.
Contemporary Okinawan Views
The views of Okinawans are far from monolithic. Many residents of base-hosting communities
appreciate the economic benefits, whether as employees on the bases, local business owners who
serve American customers, or as landowners of base property. Some locals resent the actions of
outsiders who focus on environmental issues at the expense of economic development; pro-
relocation authorities point to the village of Henoko (in Nago City municipality) as an example of
where the local citizens are more in favor of additional U.S. facilities than the broader population,
though this may have to do with the reported monetary compensation that Tokyo provides to
specific host communities. There is also a “generation gap” between older Okinawans with
personal memories of past incidents and younger residents that are not as involved in the anti-
base activist movement. Reliable opinion polls that might illuminate the extent of the opposition
to U.S. presence across demographic categories do not appear to be available.
The anti-base movement remains strong and vocal in Okinawa. Opposition to U.S. military bases
derives from two main areas: one, quality-of-life issues such as personal safety, noise, crime, and
environmental degradation; and two, pacifism and anti-militarism. These two strands are often
interwoven in the rhetoric of the anti-base movement, but not all residents oppose the U.S.
military presence on principle. There are those who support the U.S.-Japan security alliance while
objecting to the significant and disproportionate “burden” imposed on Okinawa.

The U.S. Military Presence in Okinawa and the Futenma Base Controversy

These long-held grievances burst into the forefront of Okinawan political life after a 12-year-old
girl was raped by three service members in 1995, inciting a massive anti-base protest. In
response, the bilateral Security Consultative Committee (composed of the U.S. Secretaries of
State and Defense and their Japanese counterparts, also known as the “2+2”) established the
Special Action Committee on Okinawa (SACO) to alleviate the burdens of the base-hosting
communities. SACO led to concrete changes that improved conditions on Okinawa,6 but these
occurred alongside more distressing incidents; for example, a U.S. military helicopter crashed on
the campus of Okinawa International University near MCAS Futenma in August 2004.
Ultimately, the unwillingness of Tokyo and Washington to close Futenma without a replacement
facility has fostered the perception that the two governments are discriminating against
Okinawans.
Media outlets in Okinawa contribute to this narrative by viewing many developments in the base
negotiations as further evidence of mainland discrimination. The two main daily newspapers, the
Ryukyu Shimpo and the Okinawa Times, are generally seen as left-leaning and deeply
unsympathetic to Tokyo’s security concerns. For example, in November 2011 the chief of the
Japanese Ministry of Defense (MOD) Okinawa Defense Bureau was forced to resign after a local
newspaper reported an off-the-record comment that could be interpreted as comparing MOD
actions to “rape” of Okinawa. Regional observers pointed out that the U.S. military’s
humanitarian response to the devastating March 11, 2011, tsunami and earthquake in northern
Japan received scant coverage in local Okinawan newspapers compared to the mainland press.
Although the decision to “de-link” the realignment of marines to Guam and the relocation of
MCAS Futenma was designed to improve the political climate, the media’s reaction on Okinawa
was rather negative; leaders voiced widespread concerns that the base would now remain in
Ginowan indefinitely.7
The concerns of environmental groups stem from the possible degradation of natural habitats
caused by construction of the proposed FRF at Henoko. The offshore landfill design for the
runways could involve the destruction of coral reefs and could have a negative impact on the
health and biodiversity of Oura Bay ecosystems. Activists are particularly concerned with the
plight of the dugong, a manatee-like endangered species in the Henoko Bay. The environmental
impact study conducted by the Japanese government concluded that the proposed base
construction would not do significant damage to the dugong’s natural environment, but academics
at Okinawan universities and elsewhere have disputed the report’s findings.

6 Noise reduction initiatives at Kadena Air Base reduced noise pollution for nearby residents. Six land reversion
initiatives have been completed, totaling about 1,000 hectares of the approximately 6,000 hectares slated to be returned.
The U.S. military relocated some live-fire exercises to mainland Japan, parachute drop training exercises from Yomitan
Auxiliary Airfield to Ie Jima Auxiliary Airfield, as well as some aviation training from Okinawa to Guam.

Policy Background to Base Realignment
Attempts to make the U.S. presence in Okinawa more sustainable have been underway for years.
As mentioned in the previous section, the 1996 SACO arrangement included measures “to
realign, consolidate and reduce U.S. facilities and areas, and adjust operational procedures of U.S.
forces in Okinawa consistent with their respective obligations under the Treaty of Mutual
Cooperation and Security and other related agreements.” The 1996 SACO Final Report mandated
the release of thousands of acres of land that had been used by the U.S. military since World War
II back to Okinawa, including MCAS Futenma.8 (See Figure 2 above.) Although the work was

slated to be completed within a year, political gridlock and local resistance prevented significant
progress on the agreement, a pattern that would repeat itself on a range of Okinawa basing issues
in subsequent years.
Efforts to adjust the U.S. military presence in Japan were given new impetus in 2002 by the
Defense Policy Review Initiative (DPRI), a bilateral initiative to enhance the U.S.-Japan security
alliance after the September 11, 2001, terrorist attacks in the United States. Through the DPRI
talks, the United States and Japan reviewed U.S. force posture, examined opportunities for
practical cooperation, and developed common strategic objectives. The 2005 Security
Consultative Committee joint statement listed 19 areas for alliance transformation, such as
improving interoperability, shared use of military and civilian facilities in Japan, and cooperation
on ballistic missile defense. The 2005 statement endorsed the realignment of U.S. marines from
Okinawa to Guam and the relocation of Futenma Air Station operations to a new base on the
shoreline of Cape Henoko.
The implementation plan for the DPRI is laid out in the May 2006 “U.S.-Japan Roadmap for
Realignment Implementation,” a document that has been endorsed in three joint statements of the
2+2 meetings, including one in June 2011. This document establishes the “linkages” that had
been a central point of debate until the policy adjustment in 2012: first, that the Third Marine
Expeditionary Force (III MEF) relocation from Okinawa to Guam was dependent on “tangible
progress toward completion” of the Henoko base at Camp Schwab and Japanese financial
contribution to the development of facilities on Guam; and, second, that land return for areas
south of the Kadena air base was dependent on completing the relocation of the III MEF
personnel and dependents from Futenma to the FRF and Guam. The April 2012 agreement
removes the linkages but continues to endorse the Henoko FRF.9
Overall Progress on Realignment Process
The controversy surrounding relocation of MCAS Futenma has overshadowed progress in
implementing other elements of the DPRI. With the exception of the Okinawa-Guam realignment,
the initiative has been largely successful. The Aviation Training Relocation program reduces
noise pollution for local residents by having U.S. aircraft conduct training in Guam, away from
crowded base areas. As another base impact mitigation measure, U.S. Carrier Air Wing Five
(CVW-5) will be relocated from Naval Air Station Atsugi to MCAS Iwakuni (both located on
Honshu, Japan’s largest island), where a new second runway is now operational. Beginning in
December 2012, Iwakuni will open a runway for commercial flights to and from Haneda Airport
in Tokyo.10
Other elements of DPRI have greatly enhanced interoperability and joint command and control.
In 2010, U.S. Army Japan established at Camp Zama (about 25 miles southwest of Tokyo) a
forward operational headquarters, which can act as a bilateral joint headquarters to take command
of theater operations in the event of a contingency. The headquarters of the Japan Ground Self-

Defense Forces (JGSDF) Central Readiness Force will move to Camp Zama in late 2012 to take
advantage of this new capacity.11 The Japan Air Self-Defense Forces (JASDF) Air Defense
Command facility at Yokota Air Base has been completed, enhancing coordination with United
States Forces in Japan (USFJ) headquarters. The Bilateral Joint Operations Coordination Center
at Yokota allows for data-sharing between the Japanese and U.S. air and missile defense
command elements. This upgraded facility was used to coordinate the disaster relief mission
Operation Tomodachi, the joint U.S.-Japan military response to the earthquake and tsunami that
devastated northern Japan in March 2011. In June 2011, Japan announced an agreement to allow
the transfer of jointly developed missile defense components to third countries, representing an
exception to Japan’s ban on arms exports.
The Politics of U.S. Basing in Okinawa
The politics surrounding basing issues in Japan are complex and ever-shifting, and involve
politicians from local village wards up to the Prime Minister’s office. In 2009 and 2010, Prime
Minister Hatoyama’s involvement in the Futenma controversy elevated the issue to a major U.S.-
Japan point of contention and, some assert, may have irrevocably shifted the political landscape
in Okinawa by raising and then dashing the hopes of the anti-base movement. However, his
Liberal Democratic Party (LDP) predecessors had made little progress in decades of trying to
resolve the fundamental challenges of the U.S. military presence on Okinawa. In the postwar
period, when the LDP dominated Japan’s political scene, alliance security arrangements tended to
be negotiated between political-military elites in Washington and Tokyo, often ignoring local
concerns.12 Even as democratic practices deepened and the anti-base movement became more
empowered, many leaders in Tokyo were unable or unwilling to invest enough political capital to
reduce the strains of hosting foreign troops on Okinawans.
Tokyo-Okinawa Relations
Although Washington-Tokyo relations play a role, the controversy over bases is seen by many as
largely a mainland Japan versus Okinawa issue. Due to the legacy of the U.S. occupation and the
islands’ key strategic location, Okinawa hosts a disproportionate share of the continuing U.S.
military presence. According to the Okinawan government, about 25% of all facilities used by
U.S. Forces Japan are located in the prefecture, which comprises less than 1% of Japan’s total
land area,13 and roughly half of all U.S. military personnel are stationed in Okinawa. Many
observers assert that Tokyo has failed to communicate effectively to Okinawans the necessity and
benefits of the alliance. However, Okinawa has received millions of dollars in subsidies from the
central government in exchange for the burden of hosting U.S. troops. This year, Tokyo awarded
a large amount to Okinawa for the prefecture’s economic development plan as part of the
government’s FY2012 budget: 290 billion yen ($3.7 million USD), with 150 billion yen ($1.9
million USD) designated as lump-sum grants without restrictions.14 Although the money is not

explicitly linked to the basing issues, many insiders say that this year’s generous sum is intended
to influence the governor’s decision on whether to issue the necessary permits.
Role of the Prefectural Governor
The Okinawan governor’s office wields significant influence over developments inside the
prefecture. The governor has the authority to approve or reject off-shore landfill construction,
which effectively gives him a veto over any FRF that relies on a landfill, such as the Henoko
plan. The landfill permit itself requires an environmental impact statement (EIS) that the
governor’s office reviews to ensure that the project does not significantly damage the natural
environment. In the case of the Henoko FRF proposal, the EIS has become a major point of
contention. It has been suggested that the Diet could pass a law to circumvent this approval
process, but the current governor, Hirokazu Nakaima, has threatened to lead mass protests against
any base construction that defies his authority.
In the latest Futenma controversy, Governor Nakaima has played a pivotal role. Elected in 2006
with the backing of the LDP and Okinawa’s business community, he has been seen as a
pragmatist rather than an anti-base ideologue. In his first term, Nakaima agreed to the relocation
of MCAS Futenma to Henoko with specific conditions, including moving the base slightly more
offshore. However, when Hatoyama revisited the FRF relocation plan in 2009, the political
calculus changed. The Okinawan movement against the FRF proposal was rejuvenated and
gained strong support on the island. Nakaima modified his position, taking a stronger anti-base
stance during the 2010 gubernatorial campaign against a resolutely anti-base opponent, calling for
the base to be located out of the prefecture. Nakaima justified the position by arguing that
alternate sites elsewhere in Japan would be more politically feasible and relocation could be
accomplished faster due to the many obstacles facing the FRF plan in Okinawa.
Although Governor Nakaima offered a series of stern rebukes to Tokyo officials in 2011 and
2012, he has been careful not to categorically reject the Henoko FRF plan. Rather, he has made
statements such as, “I want to hear an explanation that would be convincing to the mayor of Nago
City [the municipality in which Henoko is located] and prefectural residents.”15 It appears that the
governor’s goal is to close Futenma as soon as possible, whether that involves relocating marines
within the prefecture, to mainland Japan, or elsewhere. Some observers think that Nakaima would
agree to the Henoko FRF plan if the base-hosting municipality consents, but other analysts point
to past examples of foot-dragging and argue that Nakaima would not act against the opinion of a
clear majority of Okinawans. He stated in February 2012, “Relocation to [Henoko] is virtually
impossible and the rational option is to relocate the facilities to another region in Japan.”16

Nago City Political Dynamics
Camp Schwab and the proposed new aviation facility are located in Henoko, a ward of the larger
Nago City. The politics of Nago City mirror that of Okinawa in their complexity and tangle of
interests. A 1997 city referendum revealed a majority opposed to the new base construction, but
despite this result successive mayors declared their conditional approval.17 In January 2010, the
city elected as mayor Susumu Inamine, who strongly opposes any increased military presence.
The majority of current city council members are against the FRF relocation plan.
On the other hand, the residents who would be most directly affected have mixed, and even
positive, feelings about the proposed base, possibly due to the economic benefits for the hosting
community. A small mountain range about seven miles wide separates the designated base site in
Henoko village from the densely populated area of Nago City (see Figure 3). It is unlikely that
most people living in Nago City would experience the noise of helicopter overflights. In May
2010 the administrative council of Henoko village, where the base would be built, passed a
resolution accepting the relocation of Futenma on the conditions that the runway site be moved

17 Mayor Tateo Kishimoto announced his conditional approval of a reef-based land reclamation plan with a short
runway on September 20, 2005, and Mayor Yoshikazu Shimabukuro gave his approval for the land reclamation plan

further into the sea and that the government provide additional compensation.18 Henoko village
residents are reportedly more focused on the economic benefits of the new base and irked by the
intrusion of environmentalists.19
Heightened Congressional Involvement
In the past few years, Congress has exercised its oversight function on the military realignment
initiatives in Japan and voiced its growing doubts about the viability of the 2006 agreement.
Members of the Senate Armed Services Committee have questioned witnesses closely about the
Defense Department’s plans in the Asia-Pacific in a series of hearings, sent letters to the Secretary
of Defense outlining their reservations, and inserted language and specific provisions into
legislation to ensure that the executive branch heeds their concerns.
In May 2011, three Senators (Carl Levin (D), Chairman of the Armed Services Committee; John
McCain (R), ranking minority member of that committee; and Jim Webb (D), Chairman of the
Foreign Relations Subcommittee on East Asian and Pacific Affairs) released a joint statement that
called the U.S. military realignment plans in East Asia, and particularly those on Okinawa,
“unworkable and unaffordable.” They recommended alternatives, including transferring Marine
Corps assets to the Kadena Air Force base on Okinawa (see text box below) and moving some Air
Force assets to Anderson Air Base in Guam. Senator Webb further proposed in subsequent letters
to Secretary of Defense Panetta that co-basing arrangements with the JSDF be explored, as well
as the use of aviation facilities on Okinawa during military contingencies.

Kadena Integration Alternative
Over the years, folding some Marine Corps operations into the large Kadena Air Base has been suggested as a way to
shut down the problematic Futenma base. The idea first arose and was rejected during SACO talks in 1996. During
negotiations in 2005-2006, then-Deputy Under Secretary of Defense Richard Lawless reportedly explored the
possibility of moving helicopter operations to Kadena, but encountered opposition from the Air Force. Some analysts
have long suggested that interservice rivalry plays a significant role in styming the Kadena option. In the same round of
negotiations, the Japanese side also re-proposed the Kadena plan, only to be dismissed because of a lack of tolerance
from the communities surrounding Kadena, who already had complaints about existing noise and safety risks from the
base. Senators Webb, Levin, and McCain again suggested the alternative in 2011.
The Kadena integration plan appears to have gained little traction on either side, due to two main reasons: local
resistance and objections from the U.S. military on operational grounds. Analysts have argued that Kadena is already
at capacity and adding Marine helicopter operations would double the daily flight operations for routine training,
which would likely exacerbate the surrounding communities’ objections to the base. The space limitations may be
particularly strained in the event of a military contingency or humanitarian disaster response. In addition, some
observers have posited that spreading some Air Force operations to other positions in the region would weaken
deterrence and response flexibility. Some military analysts assert that Kadena’s capabilities are essential to U.S. power
projection capability in the Pacific and that adding more operations could risk causing a backlash that would
undermine acceptance of the base.

The U.S. Military Presence in Okinawa and the Futenma Base Controversy

Concurrent with the Senators’ statement, in June 2011 the Government Accountability Office
(GAO) released a report commissioned by the Subcommittee on Military Construction, Veterans
Affairs, and Related Agencies, Senate Appropriations Committee. The report concluded that the
Department of Defense has not adequately estimated the costs involved in transforming its
military posture in Japan and Guam nor analyzed the alternatives to existing initiatives.20 The
initial estimate was for an expense of $10.3 billion to move 8,000 marines and their dependents to
Guam, but the GAO reported that the actual costs would be more than double the DOD estimate
at $23.9 billion.21 (The DOD cost estimate for the latest plan, to move roughly 5,000 marines and
their dependents to Guam, is $8.6 billion.)
Funding Cuts and New Requirements in FY2012 National Defense
Authorization Act

Increasing alarm about the overall U.S. fiscal situation drove further scrutiny of existing plans.
Concern about the ballooning costs of the Guam construction and the uncertainty surrounding the
realignment led Congress to reject the Administration’s request for related military construction
funding in the FY2012 National Defense Authorization Act, P.L. 112-81. Section 2207 prohibits
funds authorized under the act, as well as amounts provided by the Japanese government, from
being obligated to implement the planned realignment of Marine Corps forces from Okinawa to
Guam until certain justifications and assessments are provided. These requirements include the
Marine Corps’ preferred force lay-down in the region; a master plan for the construction involved
in the plan; a certification by the Secretary of Defense that “tangible progress” had been made on
the Futenma base relocation; the submission of the independent assessment required by Section
346; and a series of plans involving the planned infrastructure and construction costs on Guam.
The April 2012 “de-linking” agreement did not appear to assuage congressional resistance. After
the announcement that the original policy would be adjusted and the base relocation and marine
redeployment de-linked, Senators Levin, McCain, and Webb wrote in a letter to Defense
Secretary Panetta that, “... we have serious questions that have not been fully addressed regarding
the emerging agreement between the administration and the Government of Japan. These
questions pertain to the core details of this or any basing arrangement, including cost estimates,
military sustainment and force management, and how it would support a broader strategic concept
of operations in this increasingly vital region. Congress has important oversight and funding
responsibilities beyond its traditional consultative role for this basing agreement, and any new
proposal should not be considered final until it has the support of the Congress.”22
CSIS Assessment
Section 346 of the FY2012 National Defense Authorization Act requires an independent
assessment of the U.S. strategic posture in the Asia-Pacific. The Center for Strategic and
International Studies (CSIS) was commissioned by the Secretary of Defense to provide the report;
CSIS delivered it in mid-July 2012 to the Secretary, who then forwarded the report with his

comments to the Senate and House Armed Services Committees. In its unclassified version, the
report broadly supports DOD’s strategy to enhance U.S. defense posture in East Asia and
recommends, with caveats, the implementation of the April 2012 agreement, including the FRF.23
While asserting that the Henoko plan is the best way forward geostrategically and operationally, it
also acknowledges the budgeting and political obstacles that confront the FRF, concluding that
other alternatives should still be explored. Among those other alternatives are Kadena Integration,
stationing of Marine air operations on an off-shore island, construction of a second runway at
Naha Airport, and remaining at the current Futenma base. The report also recommends
prioritizing infrastructure improvements on Guam that would facilitate the transfer of marines. In
a statement, Senators Webb, Levin, and McCain said that, “We agree with CSIS’s emphasis on
the need for DOD to articulate the strategy behind its force-posture planning more clearly.
Congress must also be confident that the DOD force planning and realignment proposals are
realistic, workable, and affordable.”24
Implementation Challenges in Japan
Beyond Congressional concerns, significant obstacles remain in Japan as well. Public opposition
has hardened considerably in Okinawa, with all the major political figures involved in the landfill
permit process declaring opposition to the plan. The fundamental problem of hosting foreign
troops in a crowded urban landscape, and the sense of grievance that the Okinawans in particular
have harbored for decades, seems unlikely to fade. On the other hand, proponents argue that the
April 2012 policy adjustment could allow political breathing room for figures in Okinawa who
are relatively sympathetic to the U.S. basing needs, or who see the potential for economic
development from the returned land.
Political and Financial Obstacles in Tokyo
Japanese politics have been in a state of flux since 2006, with six different prime ministers in as
many years.25 Parliamentary politics have been characterized by paralysis and obstructionism,
making coherent policy decisions difficult. Still, the last three prime ministers have endorsed the
FRF plan and the government of Japan has been able to muster the funds for the Guam relocation
agreement. Obstacles from the U.S. Congress and continued Okinawan resistance may discourage
such cooperation from Tokyo, however. Japan is facing its own fiscal crisis, particularly given the
pressing reconstruction needs in the Tohoku region, which suffered the most damage from the
devastating 2011 earthquake and tsunami. Japanese legislators may be resistant to continue
appropriating funding for the Marines’ relocation in the absence of U.S. political and financial
commitments. Current Prime Minister Yoshihiko Noda’s hold on his post is tenuous and the
opposition parties are pushing for new parliamentary elections, which could bring new leadership
to Tokyo. If progress remains essentially frozen, other alliance negotiations such as Japan’s

contribution to the costs of hosting U.S. troops, known as host nation support, could interfere
with the agreement.
Ongoing Risks of Futenma Operations
As Tokyo and Washington have struggled to overcome paralysis on the agreement, the
problematic base at the center of the controversy has remained operational but in need of serious
repair and maintenance. In recognition of the pressing repair needs, U.S. and Japanese
government officials committed to “contribute mutually to necessary refurbishment projects” at
MCAS Futenma in the joint statement issued by the Security Consultative Committee in April
2012. Although these projects are vital to continued operations at Futenma, Okinawans may
interpret the repairs as a sign that the United States and Japan do not intend to fulfill their goal of
closing the base.
The base is located within a dense urban area, surrounded by schools and other facilities that are
subjected to the high noise levels that accompany an active military training site. (See Figure 4.)
A new equipment accident or crime committed by a U.S. soldier could galvanize further
Okinawan opposition to the U.S. military presence on the island. The risks are heightened by the
anticipated increase in activity as units that have been deployed to conflicts in the Middle East
return to Okinawa. Despite the April 2012 agreement to move about 9,000 marines off Okinawa,
the absolute number of personnel and aircraft could actually rise at Futenma and other facilities in
the near term.

Deployment of MV-22 “Osprey” Aircraft to Futenma26
The U.S. military plans to deploy MV-22 Osprey transport aircraft to Futenma as early as fall
2012, a move expected to draw local protests because of safety concerns. The aircraft were
unloaded in late July at MCAS Iwakuni. The U.S. military first announced its intent to deploy the
V-22 Osprey tilt-rotor aircraft to MCAS Futenma in the 1992 “Master Plan for Marine Corps Air
Station Futenma” and reiterated this aim in the 1996 SACO draft. The Marine Corps plans to
replace the 24 CH-46E “Sea Knight” helicopters stationed at Futenma with 24 MV-22 Ospreys by
2014. The new aircraft will fly training missions in six routes over Japanese territory, including
hundreds of flights over the main island of Honshu. The introduction of these advanced aircraft to
Okinawa reportedly will enhance the operational capability of the III MEF, particularly in a rapid-
response scenario.
Japanese politicians and civil society groups have voiced opposition to the introduction of MV-22
to Japan due to the aircraft’s safety record. The crashes of V-22 tilt-rotor aircraft in training
exercises in Morocco and Florida in early 2012 reminded Okinawans of the U.S. military
helicopter crash on the grounds of a school near MCAS Futenma in August 2004.27 The governor

of Yamaguchi Prefecture, where MCAS Iwakuni is located, has asked that the U.S. military not
deploy Ospreys at Iwakuni until safety concerns are fully addressed. On July 1, 2012, Governor
Nakaima told Defense Minister Satoshi Morimoto, “We will absolutely oppose the plan [to
deploy the MV-22 on Okinawa].”28 However, the Japanese central government has not requested
that the Marine Corps cancel deployment, and local governments do not have authority to
interfere. Defense Minister Morimoto has demanded to see the full results of accident
investigations by the U.S. military. Despite the two crashes, the Osprey was not grounded and
continues to fly in the United States and elsewhere.
