Unchained Sun: Japan’s New National Security Strategy — NICKELED AND DIMED

Japan’s new National Security Strategy has taken its military spending to unprecedented levels. This marks a drastic departure from historical precedent, and has major implications for Indo Pacific security. This article will examine the historical development of the Japanese Self Defence Forces and the diplomatic and military measures outlined in the new NSS.

Background: Article 9 and the Development of the JSDF 

Kijuro Shidehara, Japan’s first post-Second World War Prime Minister 

Japan’s post-Second World War commitment to renouncing aggressive war remains one of the  most celebrated examples of a state pursuing genuinely ethics-based policies. Japan’s status as  a peace-loving nation is legally enshrined in Article 9 of its constitution. Drafted in the  immediate aftermath of the Second World War, Article 9 reflected Japan’s regrets regarding its  aggressive wars and expansionist policies, which ultimately led to the devastation of the  Japanese mainland itself.

Article 9 has two key provisions:  

I) Aspiring to an international order founded on peace, Japan renounces war as a  sovereign right of the nation, and the threat or use of force as a way of settling  international disputes. 

II) Japan will never maintain armed forces, or any war potential. The right to  belligerency of the Japanese state will never be recognised. 

The realities of the Cold War meant that almost from its inception, Article 9 began to be  interpreted in flexible terms. A surprisingly strong advocate of Japanese rearmament was its  old foe, the USA: the rise of Communism in China prompted a desire amongst US  policymakers for new military allies in Asia. 

The Korean War led to the first instance of Japanese rearmament. After US troops based in  Japan were redeployed to Korea, the US government decreed the creation of a 75,000-strong  National Police Reserve to maintain internal order and protect Japan in the case of any foreign  invasion. Despite being termed a police force, the NPR was equipped with surplus US Army  equipment. To avoid raising tricky questions vis-à-vis Article 9, military equipment was given  civilian names; tanks, for example, were euphemistically referred to as “special vehicles.”  Questions were still asked; the Japanese Socialist Party unsuccessfully requested the Supreme  Court to declare the NPR unconstitutional.  

In 1954, the NPR was reorganised into its present form as the Japanese Self Defence Forces.  This naming convention was to preserve the spirit of Article 9; according to the Japanese  government, the JSDF does not violate Clause II of Article 9 (“no armed forces or war  potential”) since it is intended purely for self-defence, and “war potential” is interpreted as the  potential to carry out aggressive war.  

Historically, categories of weapons that the JSDF is forbidden from possessing because of their  inherently offensive potential include Inter-Continental Ballistic Missiles, fixed-wing aircraft  carriers, and strategic bombers. A special prohibition is imposed on nuclear weapons; even  before Japan became a signatory to the Nuclear Non-Proliferation Treaty, its Atomic Energy  Basic Law of 1955 limited the development and use of nuclear power to peaceful uses only.  

The above prohibitions have not stopped Japan from acquiring “defensive” weapons like  submarines, helicopter carriers, or fighter aircraft. And despite never showing any inclinations,  even today, towards nuclear weapons, Japan’s extensive nuclear power plant program and  knowledge of nuclear research mean that it can develop nuclear weapons very quickly if it ever  wants to; some experts have even described it as being a “screwdriver’s turn” away from a  nuclear bomb.  

Over the years, a variety of legislation has been enacted to expand the scope of operations of  the JSDF. The Regional Affairs Law of 1999 allowed Japan to provide “rear support” to the USA  if it became involved in regional conflicts, even if Japan hadn’t been directly attacked. After  9/11, the Anti-Terrorism Special Measures Law was enacted to provide logistical support to US 

and other armed forces engaged in anti-terrorist operations across the world. In 2003, 9,600  Japanese personnel were dispatched to Iraq to carry out reconstruction and humanitarian  activities. This deployment was particularly controversial; the Nagoya Supreme Court in 2008  passed a non-binding ruling stating the mission was in violation of Article 9, specifically citing the transport of other countries’ combat personnel to battle zones by Japanese planes as a  military activity.  

Militarisation kicked into a new gear after Shinzo Abe became Prime Minister in 2012. In 2014,  Abe’s government implemented a significant overhaul of defence-related legislation. Most  consequentially, the government broadened the scope of forceful self-defence to when a close  ally of Japan had been attacked in a manner that posed an existential threat to Japan itself. This  significantly expanded the range of situations in which the JSDF could go to war – prior to this,  force could be used only if Japan itself had been attacked.  

 The JS Izumo, one of two helicopter carriers that Japan has converted into conventional aircraft carriers.  

Symbolic of Abe’s commitment to a more muscular security policy was the conversion of two  Izumo-class helicopter carriers to conventional fixed-wing aircraft carriers in 2018. This ended  the long-held interpretation that aircraft carriers were offensive weapons, and as such  prohibited to the JSDF. The government was fully aware of the optics of this move; there were  intense debates in parliament over what to call the converted vessels, with terms like  “defensive aircraft carrier” being proposed to avoid the constitutional prohibition on offensive  weapons. Finally, the term “multi-purpose destroyer” was officially adopted.  

The 2022 National Security Strategy

Prime Minister Fumio Kishida, who’s helmed the development of the new National Security Strategy. 

The first edition of Japan’s National Security Strategy was published in 2013. Then, North  Korea was identified as the primary threat to Japan, while China and Russia were described as  “strategic partners.” The new NSS takes a radically different stance; China is now termed the  “greatest strategic challenge to ensuring the peace and security of Japan.” Chinese efforts to  unilaterally change through force the status quo in the South and East China Seas, as well as  the possibility of a conflict erupting over Taiwan, are highlighted as potential flashpoints for a  China-Japan conflict.  

Russia’s extensive strategic cooperation with China, including carrying out joint military drills  near Japan, and its strengthening of its forces in its Northern Territories bordering Japan are  pointed out as inimical to Japanese security. The Strategy document notes that Russia’s  invasion of Ukraine has shown that it is not above using force to achieve its aims. The Ukraine  invasion had another important consequence: Japanese officials realised that Ukraine received  significant help from its allies only after it demonstrated a robust capability to defend itself – in  the words of the expert panel advising PM Kishida, “demonstrating that we will defend our  country ourselves is essential to maintaining the unwavering confidence of allies.” 

Finally, the document reiterates that North Korea poses a continuing threat to Japan. North  Korea’s possession of weapons of mass destruction and ballistic missiles that can target Japan  with nuclear warheads make it a clear peril to Japan.  

On the diplomatic frontier, the NSS commits Japan to the India-US-Japan-Australia Quad  Partnership. It describes Taiwan as an “extremely important partner” and South Korea, (with  whom Japanese relationships have been historically frosty, notwithstanding common security  interests) as a “highly important neighbouring country.” By committing to an alliance with  Taiwan, Japan has made clear that it regards China as its primary foe – one that cannot be  dealt with through conciliation. However, the document does state that it will seek to develop  mutually beneficial economic relations with China – in other words, induce economic  dependencies in China that will make it unprofitable for it to go to war with Japan.  

Beyond the reconfiguration of Japan’s strategic opponents and allies, the most dramatic change  imposed by the NSS is in the realm of defence spending. For decades, Japan has maintained a 

self-imposed restriction on defence spending to 1% of the national GDP. The current defence  budget is $37 billion annually; the NSS seeks to increase this over the next five years till it  reaches a sum of $80 billion per year – more than 2% of GDP. This will catapult Japan from  the ninth-largest defence spender in the world, to the third-largest.  

Part of the increase will be accompanied by simply re-classifying as defence spending certain  expenditures not previously called so. This includes aspects like the Coast Guard and public  infrastructure that can be repurposed for defence purposes in times of crisis. Beyond this, the  strategy document highlights several new areas for defence spending. These include  counterstrike capabilities, cyberwarfare, space security, and public-private partnerships for the  development of defence technology. 

The Tomahawk missile, which Japan is considering buying to enhance its counterstrike capabilities.  

Counterstrike represents a fundamentally novel capability for Japan. By giving itself the ability  to strike back at strategic targets on the home territory of any aggressor nation, Japan is trying  to increase its deterrence value. In the long-term, Japan seeks to develop and use indigenous  cruise missiles, but to provide counterstrike in the interim, it will seek to purchase up to 1,000  US Tomahawk cruise missiles – these have a range of 1,600 km, sufficient to reach targets in  North Korea and China. And despite the repeated assertions in the NSS that these weapons will  be used within the conditions of self-defence, their inherently offensive nature cannot be  denied; it was with good reason that the JSDF was prohibited from acquiring long-range  missiles until today. 

The defence industry represents another important area for investment. In order to boost the  indigenous defence industry and reduce its reliance on American weapons, Japan will subsidize  defence-related projects. At the same time, it will enter a joint-project with Britain and Italy to  develop a next-generation fighter jet to enter service by the 2030s. Finally, in order to  strengthen allies throughout the Indo-Pacific Region, restrictions on the export of defence  technology (which currently, for example, constrain weapons transfers to Ukraine) will be  loosened. 

A lesson learnt from the war in Ukraine is that modern war leads to immensely high rates of  consumption of materiel, hence reserves must be concomitantly large. Hence, a significant 

portion of Japan’s spending will go towards strengthening the overall resilience of the JSDF by  increasing stocks of munitions and fuel, and upgrading their transportation and storage  systems. Another important lesson, particularly for an inherently defensive force, is that  increasing the survivability of your strategic infrastructure is key to surviving an offensive first  strike. In Ukraine, Ukrainian pilots were trained to fly their aircraft from civilian highways in  case Russian strikes damaged the highly visible military runways; Japan’s NSS takes a page out  of this book by proposing the expansion of civilian airports so they can handle military aircraft.  This will ensure that at least some aerial capability will survive an enemy first strike.
