Was Japan’s recent Golden Week diplomatic offensive effective, let alone ‘strategic’?

Every year around this time, I find myself asking a simple question: Why do overseas trips by the country’s prime minister, Cabinet ministers and senior ruling-party figures cluster during Golden Week?

This year offers a striking example. Prime Minister Sanae Takaichi and roughly a dozen ministers fanned out across more than 20 countries, spanning the Indo-Pacific, the Middle East, Europe and Africa. Notably absent from these itineraries: the United States and China.

Does that make this diplomacy “strategic”? I remain skeptical.

The scale of activity is undeniable. Takaichi visited Vietnam and Australia. Other ministers traveled across Africa, Southeast Asia and Europe, while senior ruling-party officials made parallel trips to Central Asia, South Asia, the United States, China and even Russia. The breadth suggests energy and intent. But activity alone does not equal strategy.

To be sure, the government has articulated a purpose. Takaichi instructed her ministers to prioritize securing stable supplies of crude oil and petroleum products, developing new sources of energy and ensuring access to essential goods. Japanese media have questioned the timing and coherence of the effort, asking whether this represents a coordinated push or a reactive scramble.

A closer look at individual visits reveals some substance. In Vietnam, Takaichi agreed to support oil refinery development and strengthen rare-earth supply chains. In Australia, the two countries designated critical minerals projects as priorities and reaffirmed reciprocal energy flows, including liquefied natural gas, coal and petroleum products.

Elsewhere, officials advanced resource diplomacy. In southern Africa, Japan discussed transport routes for copper and cobalt, as well as cooperation on critical minerals. In the Middle East, commitments were secured to maintain stable crude oil supplies, including the replenishment and expansion of joint strategic reserves. In Southeast Asia, agreements covered fertilizer inputs and other essential commodities.

Taken together, these engagements reflect an evolution of the “Free and Open Indo-Pacific” vision first championed by former Prime Minister Shinzo Abe, with a sharper focus on economic security. There is also a security dimension. Japan and Australia issued a joint statement covering defense equipment maintenance, joint development and sea lane security. In Southeast Asia, Tokyo expanded defense cooperation and explored equipment transfers.

Viewed in this light, the diplomatic push appears multifaceted and, on paper, strategic.

Yet something is missing.

Strategy is not simply a collection of worthwhile objectives. It requires prioritization, sequencing and timing. It demands clarity about goals and a deliberate approach to achieving them. By that standard, the Golden Week surge raises doubts.

Cramming a wide array of high-level visits into a single week risks undermining their effectiveness. Diplomacy is not just about where one goes, but when and in what context. Successful statecraft typically involves careful calibration — monitoring other countries’ moves, choosing the right moment, selecting appropriate counterparts and aligning engagements with broader policy goals.

This burst of activity, by contrast, carries a hint of improvisation. The sheer density of travel suggests logistical convenience rather than strategic design.

There is also a structural issue. Japanese officials often argue that overseas travel is difficult while the country's parliament is in session. This constraint, they say, necessitates clustering trips during parliamentary recesses, such as Golden Week.

But this explanation is increasingly unconvincing.

Japan created a system of vice ministers in part to ensure continuity of governance, including the ability to answer Diet questions in a minister’s absence. While the Diet, the nation's parliament, is the highest organ of state power and deserves respect, it should not so constrain the executive branch that diplomacy becomes inflexible.

This tension has persisted for decades, with little meaningful reform. The result is a pattern in which Japan’s top leaders have limited opportunities for sustained, well-timed engagement abroad. The contrast with other major powers is notable: Chinese leaders, for example, regularly conduct extended tours in regions such as Africa, building relationships over time.

Japan’s recent outreach to Africa is a welcome step, but it also highlights how infrequently Japanese prime ministers have visited the continent in the past.

If Tokyo wants its diplomacy to be truly strategic, procedural reform is essential. The government must enable more flexible travel by the prime minister and Cabinet ministers, even while the Diet is in session. That, in turn, requires rethinking how parliamentary deliberations are conducted and how responsibilities are delegated within the executive.

Without such changes, Japan risks continuing a pattern of compressed, opportunistic diplomacy — busy, but not always effective.

The recent flurry of visits demonstrates ambition and a growing focus on economic security. But ambition alone is not enough. Strategy requires discipline, timing and institutional support.

Until those elements are in place, Japan’s diplomatic offensives may look strategic. Whether they actually are is another question.
