When Robert Kagan famously wrote that, in their approach to power and security, Americans are from Mars and Europeans from Venus, what might he have said about Japan? In most respects, post-modern Japan has been more like Europe than America in preferring diplomacy to force, persuasion to coercion and multilateralism to unilateralism. Indeed, it might be said that Japan is even further towards the Venusian end of the celestial spectrum in its aversion to the instruments ofmilitary power. No other country in the world explicitly renounces war as a sovereign right; or eschews the threat or use of force as a means of settling international disputes; or proscribes land, sea and air forces as well as other war potential. This deeply ingrained pacifism is all the more remarkable when one considers that Japan is not an Asian Costa Rica, but the world's second-largest economy, a major financial power and a favored candidate for a permanent seat on an expanded United Nations Security Council.

But there is another Japan--one with a long martial tradition, embodied in the ancient samurai of legend, which in the first half of the 20th century destroyed Russia's Baltic fleet, colonized Korea, invaded China and subjugated Southeast Asia before its eventual catastrophic defeat in 1945. Today, Japan is once again a leading military power, with the world's third-largest defense budget (after the United States and China) and a quarter million men and women under arms. Its Self-Defense Force (SDF) is deployed on peacekeeping operations around the world, for tsunami relief in Southeast Asia and in support of U.S.-led coalitions in Afghanistan and Iraq. More and more politicians chafe at the self-imposed constitutional restrictions on the military and believe that Japan must be more resolute and assertive in defending its vital interests, including taking pre-emptive military action, when necessary. Prime Minister Junichiro Koizumi has talked up constitutional reform and declared his desire to see Japan become a "normal country." He has even dared to call the SDF what it really is--a modern army, navy and air force.

Is this a dangerous reawakening of Japan's martial instincts and desire for hegemony, as critics maintain? Or are we seeing the emergence of a pragmatic new realism that is a natural and long-overdue readjustment to the nation's much altered and more foreboding external environment? And if so, what will be the strategic consequences of a more assertive Japan? Japan is moving away from its pacifist past towards a more hard-headed and outward-looking security posture characterized by a greater willingness to use the SDF in support of Japan's foreign policy and defense interests. This shift is evolutionary, not revolutionary. But it is gaining momentum and represents a watershed in Japan's postwar security policy that will require some new thinking in Washington as well as Tokyo.

Pacifism's Denouement

Pacifist sentiment has become so entrenched in modern Japan that the country's capacity for change is apt to be discounted, or underestimated, even by long-time Japan watchers. Granted, Koizumi's robust utterances on national security often run ahead of policy, and he is certainly not the first contemporary Japanese prime minister to seem like a hawk among doves, as Yasuhiro Nakasone's tenure in the 1980s reminds us. But the shift away from pacifism is palpable, irreversible and more broadly based than Koizumi's alone.

The most compelling evidence of the sea-change underway in Japanese attitudes towards security is the accelerating erosion under Koizumi's stewardship of the constitutional and administrative restraints on the use of force and collective self-defense. The chief cause is that a once-apathetic public is becoming increasingly concerned about the deterioration in Japan's security environment, mainly due to the spread of transnational terrorism, North Korean antipathy, and China's burgeoning economic growth and military power. Recent polls, including one conducted by the authoritative Asahi Shimbun newspaper, show that a clear majority of Japanese people and parliamentarians are now in favor of constitutional revision (kaiken), and nearly half want to abandon the prohibition on collective self-defense. Significantly, younger people are more inclined to support revising the constitution than their parents.

A contributing factor is the weakening of the coalition of interests in the Diet that has long defended the constitutional status quo (goken), especially the precipitate decline in influence of the left-leaning and traditionally pacifist Social Democratic Party (SDP). The eclipse of the SDP and its allies on the political Left has increased the probability that the war-renouncing Article 9 of the constitution will be rewritten substantially to explicitly recognize the existence of the SDF. Other likely amendments will make it easier for the government to sanction the SDF's deployment in a wide range of contingencies, although these international contributions are likely to be limited to non-combat roles for the time being. As a result, future Japanese governments will no longer be seriously encumbered by constitutional restrictions that have clearly outlived their usefulness. Any decision to dispatch the SDF will henceforth be made, as in all other countries, according to the political judgement of the government of the day and calculations of national interest.

However, revision of the constitution is not the only reason for supposing that Japan is shedding more than half a century of embedded pacifism. It is difficult for non-Japanese to appreciate the extraordinarily detailed administrative constraints on what would be considered normal defense activities in most countries. Some of these have bordered on the absurd. One senior Japanese defense official was heard to lament that tanks en route to counter an invasion would never get there in time because they were required to observe the speed limit and stop at red lights. The reason was the almost complete absence of mobilization legislation that would give the government authority to suspend civil law in the event of a military emergency.

These impediments have now been largely removed with the June 2004 passage of seven bills in the Diet. These bills augment contingency legislation enacted the previous year and designed to facilitate civil-defense cooperation between the national government and the prefectural and local authorities in the event of an emergency or an attack on Japan. The bills improve military preparedness and mobilization by allowing the Japanese and U.S. military to use seaports, airports, roads, radio frequencies and other public property in an emergency. They also permit the SDF to fire on commercial ships outside Japan's territorial waters if they refuse inspection during a crisis.

Koizumi has also steadily whittled away the normative constraints on overseas deployments of the SDF. The U.S.-led Operation Enduring Freedom to destroy Al-Qaeda's redoubt in the mountains of Afghanistan, supported by Japanese destroyers and supply ships, demonstrated conclusively that the era of checkbook diplomacy is finally over and that henceforth Japan intends to pull its weight militarily within the U.S. alliance. Iraq was an even greater break with tradition. In an unprecedented decision, Koizumi succeeded in gaining parliamentary approval to send some 600 troops to southern Iraq. The troops could only be used in non-combat roles. Samawah was selected because it was notionally free of conflict, but their very presence confirms that Japan has crossed a political Rubicon and that the government is determined to make the SDF a more usable and useful force.

Japan's Strategic Intentions

What is less clear is how the SDF will be deployed in the future, and for what purposes. There are two diametrically opposed views about Japan's strategic objectives. Those skeptical of its peaceful disposition and benign intentions contend that Tokyo is incrementally acquiring the military capabilities and strategic reach to complement its economic strength and give effect to long-suppressed regional power aspirations. Skeptics argue that Japan's expanding peacekeeping activities, government pressure to revise the constitution, cooperation with the United States in missile defense, and procurement of military platforms and weapons systems that can be used offensively are all evidence of Tokyo's hegemonic intent.

Pragmatists, on the other hand, consider the changes in Japan's security policy to be largely illusory and maintain that the government's commitment to defense reform and greater burden-sharing within the alliance is rhetorical, rather than substantive. In their eyes, Koizumi's promise of military support for the United States in Afghanistan fell far short of expectations. And despite the fanfare and flag-waving, Japanese forces dispatched to Iraq are serving in non-combat roles, forbidden to shoot other than in self-defense. Thus, there is very little prospect of Japan becoming more assertive globally or contributing much of real strategic value in East Asia, other than in the defense of Japan. A corollary is that Japan will continue to rely on the United States as a military shield while wielding the sword of mercantilism, cultivating a range of partners, including U.S. adversaries such as Iran, to hedge against economic dangers.

Curiously, neither side of this debate has grasped the real significance of the shift in public opinion or the reorientation of security policy that has been under way for more than a decade. A close examination of current Japanese attitudes towards security does not suggest the collective mindset of a resurgent hegemon. There is no political constituency for transforming the SDF into the kind of expeditionary force that would be necessary to sustain a new Japanese hegemony in Asia. With the possible exception of a small group of ultra-nationalists, who continue to harbor delusions of a return to some form of imperium, "normalizers" within the major political parties evince remarkably modest strategic aspirations.

Furthermore, the country's aging population and the existence of a resilient, mature democracy works against a revival of militarism. Given its geostrategic vulnerabilities, energy dependence and declining birth rate, Japan is hardly in a position to embark on a policy of military adventurism or expansionism in East Asia, not least because it would be vehemently opposed by China, Japan's principal competitor for regional influence, as well as its major ally, the United States.

Those who fear a return of militarism in Japan also fail to appreciate the domestic constraints on defense spending, which is legally capped at 1 percent of GDP, far lower than in most comparable countries. China, for example, spends 4.1 percent of GDP on defense, the United States 3.3 percent, South Korea 2.8 percent, France 2.5 percent, and Australia 1.9 percent. In East Asia, only Laos spends less as a percentage of GDP. Even a comparison by purchasing power parity shows Japan's per capita defense expenditure as around one quarter that of the United States and half that of France.

Although this translates into an annual defense budget of $41 billion a year, the third largest in the world, more than 50 percent goes to salaries and personnel costs. So the money available for military hardware and support systems is less than might be expected for a budget this size. Moreover, Japan's defense budget is being stretched by research and development related to the U.S. Ballistic Missile Defense Program (BMD), which will cost around $1 billion in financial year 2004/05 and an estimated $10 billion this decade, all of which will have to be absorbed within the existing budget. Thus, the scope for order-of-magnitude increases in combat power, particularly force-projection capabilities such as aircraft carriers and long-range bombers, is limited by fiscal as well as political realities.

However, eschewing the role of a regional hegemon does not mean that Japan should remain forever a strategically neutered superpower while others are free to configure the world according to their national interests and ideological proclivities. Japan's foreign policy and defense elites envisage playing a more constructive role in regional and global affairs, free of constitutional shackles, by building and shaping institutions and norms according to Japanese values and interests. This is what Koizumi means when he talks about Japan becoming a "normal" state. It also implies a greater willingness to use force and dispatch the SDF on operations beyond Japan's borders in coalitions of the willing, as well as UN-sanctioned peacekeeping operations.

These are developments that should be welcomed, rather than being a cause for alarm. What must be remembered is that unlike Europe, where war between states has become virtually unthinkable, Japan inhabits a region where interstate conflict is still a realistic prospect. It would be foolish in the extreme for Japan to emulate Europe's security approach, which emphasizes confidence-building measures to resolve intramural disputes while reserving force for out-of-area operations. The strategic balance in northeast Asia is far less stable and predictable than in Europe, and Japan's alliance obligations mandate the maintenance of a military capable of modern warfighting both at home and abroad. SDF personnel should not be seen as blue-helmeted NGOs.

Alliance Implications

But how durable is Japan's alliance with the United States, the foundation stone of its security for the past half century? Could the alliance founder, or be fatally weakened, by rising Japanese nationalism or by a reassessment in Washington that Japan matters less? There are some disturbing portents. Fewer than 10 percent of Americans feel close to Japan as a country, and China's emergence as a major trading nation has already eroded Tokyo's influence in the halls of U.S. commerce and industry. The sense of shared strategic interests that once strongly united Japanese and Americans has dissipated. Although opinion surveys show that the Japanese public continues to express support in principle for the alliance, there is strong local opposition to the U.S. presence in areas like Okinawa and Atsugi, fueled by resentment over the sexual misconduct of U.S. servicemen and the occupation of valuable public land by the U.S. military.

Even so, it is difficult to envisage the circumstances that would lead to a breakdown or hollowing-out of the alliance. After a period of neglect during the Clinton Administration, President Bush moved decisively in his first term of office to rejuvenate ties with Tokyo, reflecting the administration's assessment that a strong, regionally engaged Japan is crucial to three important U.S. strategic interests in East Asia: balancing China's rising power, providing greater logistic and intelligence support for the U.S. military, and facilitating U.S. deployments to potential trouble spots. The Pentagon knows that for political and strategic reasons it would be virtually impossible to replicate the facilities it enjoys in Japan. Guam is too far away, and the Vietnamese are unlikely to permit the United States to reoccupy its former base at Cam Ranh Bay. Australia and Singapore are useful stopovers for deployments in Southeast Asia and the Indian Ocean, but not the Taiwan Straits, where any conflict with China is most likely to be played out. Furthermore, the global realignment of U.S. military forces announced in August 2004 can only enhance Japan's strategic value to the United States as its principal Asian ally and a key base for troop deployments to the Middle East and Central Asia.

A more likely scenario is that Japan will remain within the alliance but that over time it will seek greater autonomy and equality. By any calculation, the alliance is a net strategic benefit for Japan. The U.S. nuclear umbrella still provides an unmatchable level of extended deterrence against an attack from a nuclear-armed state. This is a crucial consideration for Tokyo, since China and Russia are able to strike Japan with nuclear-armed missiles and North Korea may well possess a handful of rudimentary nuclear weapons and the means to deliver them. Moreover, the United States will be an essential counterweight to China's growing power as demographic, military and economic forces shift decisively in favor of Beijing. Fifty years ago, there was one Japanese for every six Chinese; by 2050 the ratio will be an unprecedented one to 16, based on current demographic trends. While the Japanese economy still dwarfs China's and its military packs a powerful punch, Japan's relative position isdeteriorating. If the alliance disintegrated, Japan would have to double and perhaps triple defense spending to compensate for the loss of the capabilities that the United States provides. Even then it could never replicate the unique military and intelligence assets that the United States brings to the table.

The real question for Tokyo is how to create more political and decision-making space for itself in a security partnership that can never truly be one of equals because of the disparities in size and strategic weight. Might the U.S. special relationship with the UK serve as a model, as former U.S. Deputy Secretary of State Richard Armitage and others have suggested? Despite superficial similarities--both the UK and Japan are maritime trading states anchored off the Eurasian landmass--Japan's vastly different strategic circumstances and the absence of the unique historical, linguistic and cultural ties that underpin the Anglo-American relationship suggest otherwise.

More likely is an evolutionary process in which Japan gains a greater say on issues that are central to its security concerns in Asia and looks for opportunities to encourage more collaborative behavior in its American ally. There are increasing signs of independent thinking in Japan's strategic engagement with the United States, which Washington must accept and encourage in the interests of a more mature and enduring partnership. Much of this is being driven by Japan's involvement in BMD and the need to reach agreement with the United States on a complex range of associated political and operational issues.

Currently, Japan is not able to detect and intercept incoming ballistic missiles without U.S. assistance, a conspicuous deficiency given the established arsenals of China, Russia and North Korea. In the absence of a countervailing missile capability, which is forbidden under the current interpretation of the constitution, Tokyo has opted to participate in BMD research and development. The central aim of this ambitious and still controversial enterprise is to construct a missile shield able to protect Japan against a limited strike from North Korea (although it is unlikely to be an effective prophylactic against China's or Russia's more numerous and capable missile forces).

Joint tests are expected to commence in late 2005, and the proposed system, comprising land- and sea-based interceptors, will be activated in 2007. Aside from lingering doubts about whether the shield will actually work as hypothesized, participation in BMD with the United States poses some real policy conundrums for Tokyo. Neighboring states, particularly China, are concerned that the expertise acquired in sensitive areas of missile technology would be readily transferable should Japan decide to develop its own missiles and arm them with nuclear warheads. Japanese scientists are involved in research on four components of the SM-3 missile--the propulsion system, infrared sensors, lightweight nose-cone technology and the kinetic kill warhead. China worries that Japan might export missile technology to Taiwan, and extending the shield to cover the approaches to the island could negate China's current missile advantage over Taiwan.

Over time, the future architecture and modalities of missile defense could significantly alter the power structure of the alliance and reshape Japan's approach to national security planning. Successful collaboration on missile defense would be a powerful reaffirmation of shared U.S.-Japanese strategic interests, accelerating the trend towards greater equality within the alliance and stimulating reform of the SDF's structure, organization and intelligence systems, as well as national security decision-making more generally. Already, Japanese officials have indicated their desire to have greater input into BMD planning and to share data obtained from the new FPS-XX radar system, which will improve the Pentagon's ability to track ballistic missiles targeted against the United States. Prudent self-interest dictates that Washington should be generous in sharing sensitive missile technology with Japan and be prepared to cede a measure of operational control over the system itself, if it expects Japan to cooperate fully. Conversely, Tokyo must accept that any failure to deploy an effective missile defense system or shoot down missiles bound for the United States because of constitutional niceties could rupture or severely weaken the alliance.

More fundamentally, Washington and Tokyo both need to pay greater attention to alliance management, policy coordination and addressing the imbalances in their strategic partnership. The best metaphor to describe the way the alliance works in practice is the hub (the United States) and radiating spokes (Japan, Australia, South Korea and Thailand) of a wheel. The critical dialogue is between the hub and the spokes, seldom between the spokes themselves. If the alliance is to adapt and prosper in today's vastly different strategic circumstances, the essentially uni-directional pattern of dialogue has to become more multi-directional and the alliance less dominated by U.S. interests and policy preoccupations. This will mean moving towards a more consultative, European style of alliance, which will provide Japan, Australia and the other allies with enhanced opportunities for ameliorating Washington's unilateralist tendencies and sensitizing U.S. policymakers to Asian security perceptions and political realities. In exchange, the United States should expect greater burden-sharing and collegiality in dealing with common security problems.

Calming the Dragon

As the alliance is recast, Japanese and U.S. policymakers need to consider how best to reassure a nervous Beijing that a reinvigorated Japan, working in close cooperation with the United States in Asia, is not a threat to China. This will be no easy task because of the widespread view in Chinese policy and military circles that Tokyo's strategic shift foreshadows a more assertive and possibly adversarial Japan. Of course, there is nothing new or surprising in this reaction, as Sino-Japanese rivalry has deep historical roots. It is manifest today in Chinese anxieties about Japan's support for Taiwan and BMD and resentment over legacy issues, notably Koizumi's repeated visits to the Yasukuni Shrine, which honors Japanese war dead but in Chinese eyes is a symbol of the country's imperial past. Until recently, these anxieties have been moderated by Japan's constitution and Beijing's recognition that the U.S. alliance has prevented a revival of Japanese military power. But as Japan breaks free from its constitutional shackles and the Red Sun makes its reappearance across the globe on the uniforms and flags of a reconstituted military, Chinese strategists are drawing conclusions that are troubling for future Sino-Japanese relations.

Among them is the belief that Japan wants to be a military as well as an economic power; that it is moving from a preoccupation with self-defense to accepting the broader alliance objectives of collective self-defense; that it is developing the capability to intervene militarily in the region; that the Koizumi government is playing up the North Korean threat so that it can break the constitutional taboo on collective self-defense; and that it is concealing its real strategic intentions by using peacekeeping and the War on Terror to desensitize the region to an expanded military presence.

Mirroring their neighbor's concerns, Japan is distinctly uneasy about recent double-digit increases in Chinese military spending, the acquisition of advanced fighter aircraft and naval vessels from Russia, the rapid pace of defense modernization, and the build-up of China's missile inventory. Such apprehensions are understandable. China's recently purchased advanced Kilo-class submarines can interdict the main maritime trade routes that are crucial to Japan's economic survival. Since 2000, there has been a dramatic rise in the frequency of Chinese naval incursions into Japan's exclusive economic zone (EEZ). Tokyo is particularly concerned about Chinese hydrographic surveys and oil drilling near the EEZ, as well as what appear to be intelligence-gathering operations by Chinese submarines, dramatically illustrated in November 2004 by the highly publicized incursion of a Han-class nuclear-powered submarine into Japanese waters near Okinawa.

Tensions have already flared over a number of unresolved territorial disputes at sea, notably the Senkaku Islands (Diaoyu in Chinese), which are located near rich deposits of oil and natural gas in the underlying sea bed. So far, these have been confined to polemical exchanges between Tokyo and Beijing and symbolic protests by Chinese activists. But the potential for miscalculation will increase as an energy-hungry China steps up its oil-exploration activities in the seas around the Senkakus and Japan responds by augmenting its maritime patrols and surveillance of the region. Already there are signs that for the first time the Koizumi government will allow Japanese oil companies to drill in a disputed area of the East China Sea, which would inevitably inflame anti-Japanese sentiment in China.

A critical issue for Japan is how a conflict between the United States and China over Taiwan would play out. In the event of hostilities, there is little doubt that the United States would expect Japan to provide intelligence and rear-area support for the U.S. carrier groups that would be dispatched to defend Taiwan against a Chinese attack. This would expose the SDF to a Chinese counterstrike and risk drawing Japan into direct combat with China for the first time since World War II, the consequences of which would be incalculable for both countries.

Thus, paradoxically, mutual mistrust is growing in parallel with deepening economic interdependence. The challenge for Japan is managing relations with China so that bilateral tensions do not lead to open conflict or spill over and infect the wider region. This will require a much higher level of trust between the two Asian powers than has been evident to date and a willingness to consider new mechanisms for mediating and preventing disputes so that major crises can be averted.

Unfortunately, with the notable exception of the Six Party Talks on North Korea, neither Japan nor the United States has given sufficient priority to including China in strategies for mitigating existing conflicts and preventing new ones from arising. On the contrary, the impression has been created in Beijing that closer U.S.-Japanese security cooperation is premised on containing China and diluting its military power. Missile defense is illustrative, as is the developing trilateral security dialogue (TSD) between the United States, Japan and Australia, which was established in 2001 at the U.S.-Australian ministerial talks in Canberra. From Beijing's perspective, the TSD looks suspiciously like the first step on the road to forming a new security bloc in Asia aimed at containing China. While Chinese fears that the TSD could evolve into an Asian-style NATO are misplaced and China should not be permitted to exercise a veto over U.S.-Japanese security cooperation, it makes no sense to antagonize Beijing by further institutionalizing the TSD and transforming it into a clubby, de facto trilateral alliance. A far better approach would be to create a security mechanism that allows China to discuss northeast Asia's many intractable security problems directly with Japan and the United States.

Such a mechanism already exists in the form of the Six Party Talks, which were established in 2003 to defuse and resolve the North Korean nuclear problem and which include all the northeast Asian states as well as the United States. China has rejected previous attempts to inaugurate a sub-regional security arrangement, fearing that it could be used as a vehicle for foreign intervention and meddling in China's affairs, especially Taiwan. But Beijing is more comfortable with the format of the Six Party Talks and feels some ownership of the process. So there is every prospect that the Chinese would be favorably disposed to broadening the scope and agenda of the talks atsome future date. Enlarging the Six Party Talks would be an important confidence-building measure and would provide strategic reassurance to China that should help soften its opposition to extended U.S.-Japanese defense cooperation.

The Way Ahead

The principal conclusion to be drawn from this analysis is that Tokyo's desire to pursue a more proactive security policy is not an unreasonable response to the more threatening and volatile security environment it faces. After nearly six decades of quasi-pacifism, it is time for Japan to move beyond the ideals of the post-World War II peace constitution and participate more fully in building and sustaining regional order and combating the emerging threats to security. Although fears that Japan might revert to militarism are real, they are ill conceived. Democracy and the rule of law are firmly entrenched, some constitutional restrictions on the use of force will remain, and the U.S. alliance ensures that Japan has no need for the nuclear weapons or major force-projection capabilities that would be inherently destabilizing and set off alarm bells in the region.

While the alliance once had been likened to dosho imu--lovers sharing the same bed but dreaming different dreams--Tokyo and Washington are increasingly sharing the same dreams. However, the administration needs to recognize that for all Koizumi's reforming zeal in foreign affairs and defense, domestic and regional realities will continue to circumscribe Japan's capacity to support the United States militarily. For its part, Tokyo must accept that a regression to the lackluster economic performances of the previous decade and a perceived unwillingness to pull its weight militarily could one day force a hard-headed reassessment of Japan's strategic and economic value in Washington and elsewhere. A weakened U.S.-Japanese alliance and the beginning of a long-term decline in Japanese power could foreshadow an extended period of uncertainty and destabilizing strategic change that would be detrimental to both countries' interests. A diminished, less-influential Japan would weaken Washington's voice in Asia's affairs.

The best way to preclude this outcome is for the administration to keep relations with Japan at the top of its Asian policy agenda, in recognition of Japan's centrality to the alliance and to East Asia's stability. However, in his eagerness to enlist Japan in the War on Terror and in support of U.S. global security interests, President Bush must be careful not to be too prescriptive or to pressure Tokyo into decisions on military acquisitions and deployments that raise the specter of a resurgent Japanese hegemon. At the same time, Bush must make clear his opposition to Japan acquiring nuclear weapons or major power-projection capabilities such as long-range bombers or aircraft carriers. This would be inherently destabilizing and ultimately antithetical to Japan's own security interests.

Finally, Chinese insecurities will have to be addressed. Although the old adage that two tigers cannot live together peacefully on the same mountain no longer holds true in today's global village-where tigers of all kinds coexist to mutual benefit--amicable Sino-Japanese relations cannot be assumed. Some creative new security architecture is required to help manage and alleviate the inevitable tensions ahead. U.S. policy has to be mindful of China's legitimate security concerns but strike an appropriate balance between kowtowing and needless hostility, to Asia's rising power.
