Japan is entering a new chapter in its defence policy. A country\nknown for decades as a peace state with strict restrictions on the use\nand export of military power is now opening space for the sale of\ndefence equipment abroad.<\/p>\n
This change is not merely technical but touches on historical\ndimensions, national identity, and the balance of power in the\nIndo-Pacific. It also reflects a new reality: security can no longer be\nmanaged in isolation, even by advanced nations.<\/p>\n
Substantively, the change is implemented through revisions to Japan\u2019s\ndefence equipment and technology export policy. The Japanese government\nis relaxing the framework of the Three Principles on Transfer of Defense\nEquipment and Technology, thereby enabling the export of military\nequipment, including lethal categories, to partner countries that have\ndefence cooperation agreements with Japan.<\/p>\n
Previously, exports were heavily restricted and generally covered\nnon-lethal categories such as logistics, rescue, or surveillance. With\nthis revision, Japan is entering new territory as a potential supplier\nin the global defence supply chain (The Economist, 2026).<\/p>\n
The drivers behind this change are structural. First, the growing\nmilitary power of China and its increasingly assertive posture in the\nEast China Sea and South China Sea create strategic pressure for Japan.\nSecond, threats from North Korea, particularly its missile and nuclear\nprogrammes, continue to be a source of security uncertainty.<\/p>\n
Third, and perhaps most significantly, is the emerging doubt over the\nconsistency of US security commitments. In this context, the statement\nthat \u201cno country can maintain its security alone\u201d reflects Japan\u2019s new\nawareness that security is now collective and interdependent (The\nEconomist, 2026).<\/p>\n
Within this framework, arms exports are no longer viewed solely as an\neconomic activity but as a geopolitical instrument. Japan seeks to build\nwhat can be called networked security, strengthening its strategic\npartners so they can contribute to maintaining regional balance.<\/p>\n
By bolstering the capabilities of other countries\u2014such as Australia,\nIndia, or Southeast Asian nations\u2014Japan indirectly strengthens its own\nposition. This is a form of deterrence not based solely on national\npower but also on networks.<\/p>\n
Reactions to Japan\u2019s move are varied and reflect the complexity of\nregional politics. China is the most vocal opponent of the policy.\nBeijing accuses Japan of returning to the path of \u201cmilitarism\u201d, a term\nladen with memories of the Second World War.<\/p>\n
However, behind the rhetoric lies genuine strategic concern. A more\nmilitarily active Japan\u2014especially if integrated into US alliance\nnetworks\u2014could strengthen countries in dispute with China and reduce\nBeijing\u2019s room for manoeuvre in the region (The Economist, 2026).<\/p>\n
Conversely, the United States tends to welcome this change\npositively. From Washington\u2019s perspective, Japan\u2019s step represents the\nburden-sharing it has long advocated, namely a more balanced\ndistribution of security responsibilities among allies. In a situation\nwhere the US faces multiple fronts\u2014from Ukraine to the Middle East\u2014the\npresence of more capable and independent allies becomes a strategic\nasset. Japan that can produce and even export defence equipment will\nhelp strengthen the security architecture that has long been supported\nby the US.<\/p>\n
In Southeast Asia, responses are more nuanced. No collective ASEAN\nstatement has emerged as an organisation, but several member countries\nview Japan\u2019s move pragmatically. The Philippines, facing direct pressure\nfrom China in the South China Sea, is likely the most open to increased\ndefence cooperation with Japan.<\/p>\n
Meanwhile, other countries like Indonesia, Vietnam, and Singapore\ntend to adopt a more cautious stance, though they still see\nopportunities, particularly in access to maritime defence technology.\nTherefore, ASEAN\u2019s reaction is better understood as country-by-country\nresponses rather than a single regional stance (Reuters, 2026; ASPI\nStrategist, 2026).<\/p>\n
This stance reflects ASEAN\u2019s tendency to avoid alignment with major\npower blocs and opt for a hedging approach. In simple terms, hedging is\na \u201cplay it safe while keeping all options open\u201d strategy, namely not\nfully siding with one power but still engaging in cooperation with all\nrelevant parties.<\/p>\n
In practice, ASEAN countries can deepen economic ties with China\nwhile at the same time enhancing security cooperation with the United\nStates, Japan, or other partners. This approach allows them to reap\nbenefits without losing strategic manoeuvrability. Therefore,\nopportunities for cooperation with Japan will be viewed pragmatically,\nnot as alignment in broader geopolitical rivalries.<\/p>\n
South Korea shows an ambivalent response. Historically, memories of\nJapanese colonialism remain a sensitive factor in domestic politics.\nHowever, strategically, Seoul also recognises the importance of\ntrilateral cooperation with the United States and Japan in facing North\nKorea and China.<\/p>\n
Thus, South Korea\u2019s stance can be understood as uneasy acceptance:\npragmatic acceptance but historical wariness. North Korea, for its part,\nwill almost certainly condemn Japan\u2019s move harshly and exploit it to\nreinforce its narrative of external threats that has long justified its\nmilitary programme.<\/p>\n
From a critical perspective, Japan\u2019s policy carries the classic risks\nin international relations, namely the security dilemma.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/japan-opens-doors-to-arms-exports-between-history-and-security-realities-1777460483", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
