Japan’s 2022 National Security Strategy named China as the country’s “greatest strategic challenge,” and most of the Asia-Pacific responded not with alarm but with arms deals. The Philippines, Australia, Malaysia, Indonesia, and India have all deepened defense ties with Tokyo since. Australia agreed to buy Japanese Mogami-class destroyers; Indonesia is negotiating for retired Asagiri-class ships. Beijing’s warnings of a remilitarizing Japan have moved almost no one outside China.
Japan’s defense budget hit roughly USD 51 billion in 2023, a 26.3% jump. The number that matters more is how small it looks beside the country it is meant to balance.
For two decades, the Chinese Communist Party has run the same play. It invokes the 1930s and 1940s, warns of a Japan slipping back toward militarism, and waits for the region to flinch. Once, that worked. Through the early 2000s, capitals from Manila to Canberra kept Tokyo’s military at a polite distance, mindful of a history nobody wished to relive.
That campaign has now largely failed. The Second World War ended 81 years ago, and across the Asia-Pacific the governments that lived through Japanese occupation are signing defense agreements with its grandchildren. The shift is not subtle. Japan now sells warships to Australia, trains alongside Philippine troops, and discusses transferring destroyers to Indonesia and Malaysia.
The question is no longer whether the region fears a stronger Japan. It is why Beijing keeps insisting it should, when the evidence says otherwise.
The arithmetic the region can read
Tokyo’s 2022 strategy did something previous documents avoided. It named China directly as the threat, dropping the softer language of earlier decades. The 2022 National Defense Strategy committed Japan to “counterstrike” capabilities, including long-range missiles, and to lifting defense spending toward 2% of GDP by fiscal 2027. The full text sits on the Cabinet Secretariat’s National Security Strategy page, and it reads as a response to capability, not a revival of ambition.
Sheila A. Smith, senior fellow for Asia-Pacific studies at the Council on Foreign Relations, argues that Japan’s record spending and counterstrike plans are driven by China’s growing forces and North Korean missiles — and that most regional partners quietly support a stronger Japan. The deals bear her out. In 2015, Tokyo signed its first defense-equipment transfer agreement with an ASEAN state, the Philippines, opening the door to later transfers of patrol vessels and radar.
The economic groundwork came first. Under its Free and Open Indo-Pacific policy, Japan provided roughly USD 19 billion in official development assistance to ASEAN members between 2016 and 2022, much of it building ports, rail, and coast guard fleets. For a Philippine naval officer training under the Balikatan exercise alongside Japanese ground forces this year, Tokyo is not an old occupier. It is the country that financed the patrol boat under his feet.
That said, the welcome is not universal. Rory Medcalf of the Australian National University notes that trust in Japan’s democracy underpins regional acceptance — a trust that parts of South Korea’s politics still withhold.
The agreements are real and the money is documented. What they do not explain is why Beijing keeps fighting a battle it is plainly losing.
Beijing built the memory it now sells
The grievance campaign is younger than it looks. For decades after the war, China accepted Japanese aid and investment without much public fuss — Tokyo’s development assistance helped build the China that now objects to it. The aggressive stoking of wartime resentment is roughly a 20-year-old project, timed to a generation that never saw the 1940s.
It served domestic politics well and foreign policy badly. The same Beijing that warns of Japanese militarism sends millions of tourists to Japan each year, with about a million Chinese residents living there. The contradiction is not lost on smaller capitals watching both.
Here is the scale the warnings ignore. Japan’s defense budget is a fraction of China’s, and every navy in the region knows it. That is the heart of the matter.
What rarely surfaces is how Japan’s economic footprint underwrites its acceptance. Ports, rail, energy grids, and coast guard ships across Southeast Asia and the Pacific quietly run on Japanese loans and maintenance. By the time defense ties deepen, elites in many capitals already count Tokyo as a stakeholder in their prosperity — which is why the region does not fear a stronger Japan. It fears the country Japan is arming against.
Beyond the headline
The power behind it
The decisive force shaping views of Japan’s military revival is not nostalgia or wartime memory but present-day anxiety about China’s behavior at sea and around Taiwan. Governments that once kept Tokyo at arm’s length now see its capabilities as one of the few tools they can plug into quickly to shift Beijing’s cost-benefit math — without openly choosing sides in a U.S.—China contest.
The regional split
A sharp divide is emerging between countries whose security rests on maritime trade routes and those whose politics remain ruled by unresolved history. Southeast Asian coastal states and Australia tend to prioritise deterrence and welcome Japanese hardware and training. Parts of South Korea’s political spectrum and China’s leadership elevate historical grievance instead, creating a narrative gap outsiders often mistake for region-wide fear of Japan.
What isn’t being said
What rarely reaches official speeches is how much Japan’s economic weight buys its security acceptance. Ports, railways, energy grids, and coast guard fleets across the region depend on Japanese loans and technology. By the time defense cooperation deepens, many capitals already treat Japan as a long-term partner in their prosperity, making alarm about remilitarisation costly to voice.
What the destroyer deals mean for your exposure
With Japan’s next defense budget due before the Diet in late 2026 and several equipment-transfer talks still open, three groups should be reading the fine print now.
- Policy analysts and Indo-Pacific risk teams
Read Japan’s 2022 National Security Strategy on the Cabinet Secretariat site (cas.go.jp) to see exactly how Tokyo frames China and its buildup plans. It is the baseline for judging whether the late-2026 budget sustains the path to 2% of GDP or quietly slips.
- Defense and logistics firms
Track Japan’s Ministry of Defense updates (mod.go.jp/en) on new Reciprocal Access Agreements and equipment transfers. Each signed deal sets the technical standards — and the maintenance contracts — that decide where Western suppliers fit in over the next decade.
- Investors with regional supply-chain exposure
Watch whether ASEAN partners activate or stall their Japanese destroyer talks through 2026. Activation signals deeper integration and steadier sea lanes; a stall signals partners hedging back toward China, and a risk profile worth repricing.
Explainer
- Chinese Communist Party
- The single ruling party of the People’s Republic of China since 1949. It governs without electoral competition and controls the state, military, and most major media. Its sustained campaign to stoke wartime resentment against Japan dates to roughly the early 2000s, a deliberate turn after decades of accepting Japanese aid largely without public complaint.
- ASEAN
- The Association of Southeast Asian Nations, a ten-member bloc founded in 1967 to promote regional cooperation. Its members include the Philippines, Indonesia, Malaysia, Vietnam, and Thailand, several of which now hold defense ties with Japan. Tokyo’s first-ever defense-equipment transfer deal with an ASEAN state was signed with the Philippines in 2015.
- Official development assistance
- Government aid designed to promote economic development in recipient countries, through loans, grants, and technical support. Japan has long ranked among the world’s largest providers, channelling roughly USD 19 billion to ASEAN between 2016 and 2022. Much of it funded coast guard vessels and ports that later became the physical groundwork for security cooperation.
