A Pacifist Giant Changes Course
For decades, Japan held firm to one of the most distinctive foreign policy positions in the world: it would not export lethal weapons. The ban, rooted in the country's post-Second World War pacifist constitution, kept Japan on the sidelines of the global arms trade even as it quietly became one of the most technologically advanced nations on Earth.
That era is now over.
Japan has lifted its ban on lethal weapons exports, a move that CBC's Andrew Chang breaks down in the latest episode of About That. It's a seismic shift — not just for Japan, but for the entire architecture of Western defence alliances, including Canada's.
Why Japan Is Making This Move Now
The timing is no accident. The Indo-Pacific security environment has changed dramatically in recent years. China's military build-up, North Korea's continued missile tests, and Russia's ongoing war in Ukraine have all contributed to a reassessment of how democratic nations protect themselves and support one another.
Japan, long sheltered under the U.S. security umbrella, is rethinking what self-reliance looks like in the 21st century. Lifting the weapons export ban is part of a broader push to increase defence spending, modernize its military, and play a more active role in the rules-based international order.
What Japan Could Offer the Global Defence Market
Japan's defence industry is formidable. Despite the export ban, Japanese manufacturers continued developing advanced military technology — ships, aircraft components, radar systems, and more — primarily for domestic use. Now, that technology could flow outward.
This matters because Japan produces sophisticated equipment that complements what the U.S., U.K., and other NATO-adjacent partners already field. For countries looking to diversify their defence supply chains, Japan becomes a credible new option.
The Canadian Angle
Canada, as a member of NATO and a close ally of both the U.S. and Japan through various Pacific partnerships, is paying attention. Ottawa has been under pressure for years to increase its own defence spending toward the NATO target of two percent of GDP — a commitment Canada has repeatedly missed.
Japan's strategic pivot adds fresh urgency to that conversation. As democratic nations lean into deeper defence cooperation, Canada risks being seen as a weak link if it doesn't keep pace. At the same time, Japan's move opens potential new avenues for defence procurement and industrial partnerships that Canadian companies could benefit from.
There's also a broader signal here: the post-Cold War assumption that economic interdependence would prevent large-scale conflict is being quietly retired. Nations that built foreign policy around trade relationships are now recalibrating toward security relationships — and Canada is no exception.
A New World Order in the Making?
It would be an overstatement to say Japan's weapons export decision reshapes the world overnight. But it is one more data point in a clear trend: the liberal democracies that shaped the post-1945 order are actively remilitarizing, and the norms that governed defence for the past 80 years are being rewritten in real time.
For Canadians trying to make sense of a rapidly changing world, Japan's shift is a reminder that the rules everyone took for granted are very much up for debate.
