As Canadian Prime Minister Mark Carney touches down in Tokyo this week, he steps onto a geopolitical chessboard that has been radically reconfigured since the last time a Canadian leader sought to deepen ties in the Indo-Pacific.

The liberal international order that Ottawa once navigated with ease has fractured. In its place is a cold, hard realism defined by the return of great power rivalry and the transactional “America First” doctrine of U.S. President Donald Trump’s second term.

Carney, a technocrat with a reputation for intellectual seriousness, arrives seeking to revitalize Canada’s stagnant economy through a trade and economic security agreement with Japan. But if he expects his counterpart, Prime Minister Sanae Takaichi, to be merely a partner in diversification away from the United States, he is misreading the room. For Tokyo, the value of Canada is not just in its resources, but in its utility to the central pillar of Japanese survival: the U.S.-Japan security alliance.

Japan views Canada as a like-minded nation, certainly. But in the calculus of the Kantei (the prime minister’s office in Tokyo), Ottawa is useful primarily to the extent that it strengthens the U.S.-Japan alliance and helps anchor American power in the Pacific. Any attempt by Canada to use Tokyo as a hedge against Washington or to complicate Japan’s delicate management of Trump will find no purchase with Takaichi.

To understand Japan’s position, one must understand the transformation Tokyo has undergone. As detailed in recent analyses of Japan’s strategic shift, the days of the “Yoshida Doctrine” — relying entirely on the U.S. for security while focusing solely on economics — are over. Faced with a Chinese military buildup that dwarfs anything seen in recent history, Japan has doubled its defense spending, acquired counterstrike capabilities and shed its pacifist constraints.

Takaichi, a conservative realist, has been explicit: A Chinese assault on Taiwan would constitute an existential threat to Japan. Her government is not interested in the performative “values diplomacy” that characterized previous Canadian foreign policy. Japan’s priority is preventing Chinese hegemony from emerging in the Indo-Pacific. Tokyo is building a web of deterrence — a "security diamond" involving Australia, India and the U.S. — and it wants Canada to be a functional part of that architecture, not a moralizing bystander.

The elephant in the room during the Carney-Takaichi summit will be the United States. The Trump administration’s 2026 National Defense Strategy makes it clear that the U.S. is done subsidizing the defense of free-riders. The “Trump Corollary” to the Monroe Doctrine signals a U.S. administration intensely focused on homeland defense and transactional reciprocity.

Japan has adapted to this reality with a sophisticated "bonding strategy." Tokyo has worked tirelessly to convince Washington that Japan is an asset, not a dependent. It has harmonized its defense posture with the U.S., integrated its command structures and actively supported American initiatives to ensure continued U.S. engagement in Asia.

This creates a strict boundary for Carney. Anti-Trump or anti-American initiatives will find no market in Tokyo. While Carney’s electoral victory in 2025 was fueled in part by an “elbows up” stance toward Washington’s protectionism, bringing that rhetoric to Tokyo would be a diplomatic fatal error. Japan cannot afford to alienate the U.S. and it will not align with a middle power that seeks to do so. Tokyo wants Canada to be a bridge to Washington, not a wedge.

If Canada wants to secure the economic partnership Carney seeks, it must bring hard assets to the table that support Japan’s strategic goal of de-risking from China.

First and foremost is energy and critical minerals. Japan’s economic security legislation is designed to sever dependence on Chinese supply chains for batteries, semiconductors and advanced technology. Canada has the potash, lithium and cobalt Japan needs, as well as the liquefied natural gas to secure its energy grid. However, Japanese investors have grown weary of Canada’s regulatory paralysis. Tokyo needs a guarantee that Canada can actually dig and ship these resources, turning potential into kinetic economic security.

Second, Japan expects Canada to treat the security of the Taiwan Strait as an international public good. This means more than just statements of concern. It means the Royal Canadian Navy must engage in regular, visible transits through the waters between Taiwan and China. Beijing views the strait as a domestic lake; Tokyo views it as a vital artery for its survival. If Canada wants to be a Pacific player, it must show up in the Pacific.

Third, Carney must publicly recognize China as a global disruptor. The era of trying to have it both ways — seeking trade with Beijing while whispering security concerns to allies — is over. Japan has faced Chinese economic coercion, from rare-earth bans to seafood embargoes. It respects partners who are clear-eyed about the threat. Evangelizing about human rights or diversity policy, while noble in intent, is not the currency of the realm in Takaichi’s Tokyo. The currency is cyber cooperation, disinformation countermeasures and industrial integration.

For Carney, the path to a successful summit involves a specific "to-do" list that moves beyond traditional trade talks.

First, he must propose concrete initiatives to strengthen U.S. relations with both Japan and Canada. A trilateral framework on critical minerals security, involving Washington, Tokyo and Ottawa, would be music to Takaichi’s ears. It would signal that Canada understands the assignment: strengthening the collective resilience of the U.S. alliance network.

Second, Carney should commit to enhancing the human capital ties between the two nations. We need a massive increase in the number of Canadians studying in Japan and Japanese students in Canada. This is not merely cultural exchange; it is the "soft" hard power necessary to build a generation of leaders who understand the Indo-Pacific reality.

Third, Carney must demonstrate that Canada is serious about its own decline in global performance rankings. As recent data shows, Canada’s productivity and gross domestic product per capita have lagged, threatening its status as a Group of Seven peer. Japan, having battled decades of stagnation to emerge as a revitalized power, can offer lessons, but it ultimately seeks strong partners. A Canada that is economically frail is a liability to the alliance network.

The logic of the moment is inescapable. Japan is facing a revisionist China that seeks to rewrite the map of Asia. The United States is a volatile but indispensable superpower demanding burden-sharing. Canada is a middle power seeking relevance and markets.

The solution for Canada is not to seek an alternative to the U.S. in Japan, but to join Japan in the project of keeping the U.S. engaged. Tokyo views the trans-Pacific relationship as a triangle. If the Canada-U.S. side is weak or if the Canada-Japan side is disconnected from the security reality, the structure collapses.

Prime Minister Carney has the opportunity to redefine Canada’s role in the Pacific, not as a peripheral trading state, but as a core component of the economic and security architecture that deters aggression. But to do so, he must accept the world as it is, not as Ottawa wishes it to be.

As I wrote last week, there is an ancient proverb that captures the perilous reality facing today’s Japan: Zenmon no tora, kōmon no ōkami (A tiger at the front gate, a wolf at the back gate). Takaichi’s government knows it must feed the American wolf — with investment, with defense spending and with loyalty — to survive the Chinese tiger. Canada’s peace, prosperity and security depend on realizing that the wolf is necessary for us both and that our only path forward is to help Japan keep the wolf fed, the gate secure and the tiger at bay.
