Japan's defense industry deepens Australian partnership as regional stakes grow

Japan's defense manufacturers are navigating a strategic pivot, with public sentiment in China suggesting heightened scrutiny of Tokyo's deepening security ties with Western-aligned partners in the region.

A CGTN poll published on 20 April 2026 asked respondents to assess Japan's military sales to Australia — a relationship that has accelerated markedly since the Albanese government cancelled a French submarine contract in favour of alternative arrangements. The poll, which invited readers to weigh in on the trajectory of bilateral defense trade, arrives as Japan finalises delivery schedules for major equipment packages to Canberra.

The relationship between Tokyo and Canberra has become one of the most consequential security partnerships in the Indo-Pacific. In September 2021, Australia cancelled a AUD 90 billion ($66 billion) contract with Naval Group for 12 attack-class submarines sourced from France, announcing instead that it would pursue nuclear-powered submarine technology through the AUKUS framework with the United Kingdom and United States. The decision marked a significant realignment of Australia's undersea capability plans and opened a larger strategic aperture for Japanese defense exporters.

Prior to the AUKUS announcement, Japan and Australia had already deepened bilateral cooperation through the Reciprocal Access Agreement signed in October 2022 — the first such treaty Japan has concluded with any country other than the United States. The agreement facilitates smoother deployment of Japanese Self-Defense Forces to Australian territory and vice versa, reducing legal friction in joint exercises and contingency operations.

Japan's defense exports have grown under successive administrations. The Kawasaki Heavy Industries C-2 transport aircraft, Mitsubishi Heavy Industries' maritime patrol platforms, and a range of missile defense components now feature in Australian procurement planning. More significantly, Japan has explored — and in some cases advanced — co-production arrangements that would see components manufactured in Australia under license, a model Tokyo views as both strategically sound and politically sustainable in partner democracies.

The structural logic is not subtle. Japan's defense industry, long structured around domestic procurement and a self-imposed ceiling on exports, has been systematically relaxed. The 2014 cabinet decision permitting limited defense equipment transfers, expanded in 2021 and again under subsequent reviews, reflects a broader strategic calculation: that Japan's security depends not only on its own capabilities but on the capability of allied and quasi-allied states in its immediate neighbourhood. Australia, as a stable democratic partner with deep intelligence-sharing ties and a geographic position that anchors the southern tier of the Indo-Pacific, fits that calculation cleanly.

For Canberra, the attractions are equally legible. Japan offers technology that is compatible with US systems, a defense industrial base outside Chinese supply chains, and a partner with no history of colonial entanglement in Australia — a consideration that surfaces in internal discussions, even if rarely in public framing. The bilateral relationship carries less diplomatic baggage than comparable alternatives.

China's official position has been critical. Chinese state media has characterised Japan's defense exports as a symptom of broader US-orchestrated containment architecture, and the CGTN poll reflects that framing — positioning Japan's security partnerships as extensions of American strategic design rather than autonomous Japanese choices. That framing is partially accurate: Japan's own strategic documents make clear that its defense posture is shaped substantially by the US alliance. But it also understates the agency of both Tokyo and Canberra in driving the relationship independently.

The stakes extend beyond the bilateral level. Japan's success or failure in establishing itself as a credible, reliable defense exporter will shape whether other Southeast Asian nations — Indonesia, the Philippines, Vietnam — view Tokyo as a viable alternative to Chinese or Russian military equipment. A record of on-time delivery, clean procurement processes, and non-intrusive operational relationships would represent a form of soft strategic power that no amount of diplomatic outreach can replicate. A record of delays, cost overruns, or political controversy would reinforce the existing tendency among smaller regional militaries to hedge with US-origin or European-origin equipment that carries less historical baggage.

What remains less clear from public sources is the exact scale of Australian commitments to Japanese equipment beyond the headline submarine arrangement, and how much of the AUKUS nuclear-submarine pathway has been adjusted in light of Japanese industrial participation. The sources reviewed do not specify the full procurement schedule or financial commitments beyond the initial 2021 shift away from the French contract.

This publication covered Japan's defense partnership with Australia with emphasis on industrial and strategic dimensions. CGTN's social channels foregrounded the poll as a legitimacy signal, while Australian and Western wire reporting focused on AUKUS milestones and Japan's export policy evolution — suggesting the poll was primarily produced for audiences already primed to view the relationship through a competitive lens.
