Japan’s military, among world’s strongest, looks to build This article describes Japan’s recent initiative sot substantially expand its defense forces under a “watered down” Article 9.
Background — Offensive/Defensive This article discusses the difficulties of distinguishing between offensive and defensive weapons.
Ryo Hinata-Yamaguchi takes on the clearest change in capability by stressing the Japanese need for airpower as a vital part of its naval strategy. While Japan is acquiring a large number of F-35Bs and the flat-top ships to deploy them, Hinata-Yamaguchi argues that this material acquisition is outpacing the doctrinal development needed for its operation. Moreover, the amount of resources Japan is willing to spend may create an expensive force unable to have much strategic effect given the large bureaucratic and operational hurdles fielding a credible naval aviation component would require. He advocates sufficient development for both sea control and denial missions but acknowledges that this will not come cheap.
Complementing Hinata-Yamaguchi, Benjamin Schreer assesses the other major ongoing capability development: Japan’s expensive effort to build up its amphibious capability. While noting the several roles a modest amphibious arm can play in day-to-day and humanitarian operations, Schreer does not believe a capable force deployed on big-deck ships to be worth the cost. He points out that the U.S. Marine Corps — with its eye towards the Pacific theater — is forgoing amphibious assault as its core mission and wonders why the JSDF is shifting towards it. He concludes that a special operations capability may provide the most bang for the amphibious buck.
Masashi Murano makes the case for an offensive strike missile capability that could selectively reach the Chinese mainland to deter by denial rather than punishment. As with the previous two pieces, Murano identifies another ongoing Japanese acquisition effort that is both too small to be effective as planned and lacks any concept of operations. Murano attempts to distill a philosophy for the employment of an offensive missile capability by systematically going through its possible uses. He concludes by advocating a new class of larger warheads necessarily carried by ballistic, possibly hypersonic, missiles designed to “mission kill” a sufficient chunk of the Chinese air force and navy to deter by denial Chinese adventurism. Like so many of these other capabilities, however, the price may make such a capability impossible.
Finally, Saadia M. Pekkanen addresses the considerable but not widely recognized Japanese capability in space, arguing for Japan to drop the pretense and build credible anti-satellite weapons. She makes a plausible if controversial argument that this might be the least escalatory of the four proposed changes, even as it has a potentially massive impact on the strategic balance in the region by holding much of China’s reconnaissance strike complex at risk.

Japan ’s Defense Readiness: Prospects and Issues in Operationalizing Air and Maritime Supremacy “Regardless of whether the Japanese constitution is revised, the JSDF’s essentially defensive orientation toward ensuring Japan’s security will remain unchanged. Developments to date have not altered Japan’s defense-oriented posture, and certainly have not revived the militaristic policies of the imperial years. Rather, recent improvements have focused on smoothing the operation of the mechanism that allows Japan to exercise the necessary capabilities for self-defense within the nation’s strategic, political, and legal frameworks. Moreover, the developments further confirm that the JSDF is strong when measured within a context of close coordination with the United States and other like-minded states.”

“Extended Deterrence and Strategic Stability in Northeast Asia,” NBrad Roberts has analyzed how the United States and Japan can avoid a “security deficit” in the region.6 He briefly outlines the new threat that long-range missiles from the DPRK pose to Japan, discusses the risks of the United States not upholding alliance commitments, and explains the stability-instability paradox vis-à-vis China. Roberts argues that to maintain credible deterrence in Asia, the United States and its allies must demonstrate collective resolve against threats and work on deterring conventional provocations.7 He suggests that Japanese strike capabilities would strengthen deterrence, especially in “grey zone conflicts.”8 Moreover, he proposes that Japan’s acquisition of ballistic missiles might aid the United States in achieving a conventional prompt global strike capability. Roberts briefly mentions possible Chinese reactions but prioritizes maintaining the credibility of the U.S. nuclear umbrella and “strategic stability” in the region.

Should Japan adopt conventional missile strike capabilities? With North Korea’s growing nuclear capabilities and China’s increasing military assertiveness in the Asia-Pacific, the issue of Japan’s right to defend itself via a conventional first-strike capability has regained salience in the security discourse. High-level interviews and in-depth analysis, however, show that the main three arguments for Japan to seek an offensive strike capability are not justifiable in the current political and economic environments. First, developing a conventional missile strike capability is not a practical solution for Tokyo to abate the North Korean threat, and the move could be perceived by Beijing and Seoul as aiding a U.S. strategy of containment. Second, the current political restrictions on the Japanese defense budget would not practically allow the buildup of the military capability required for a conventional missile strike force, and this restriction cannot be changed without support from a military-wary public. Finally, though the U.S.-Japan alliance may be unbalanced in terms of capabilities, the U.S. should consider its broader interests in regional stability. A strike-capable Japan may not only escalate tension in an already tense relationship with China, it also could elicit a harsh response against Tokyo and Washington. This could challenge the credibility of the U.S. “nuclear umbrella,” potentially leading to increased militarization throughout Asia.
Japan: pressure from populist right to scrap ‘peace constitution’ after 75 years nternationally, it will send alarm bells ringing across the Asia-Pacific. Any indication that Japan might revise its constitution is likely to spark angry reactions from Japan’s former colonies and victims of militarist wartime aggression.
