When Japanese Prime Minister Sanae Takaichi meets U.S. President Donald Trump in Washington on Thursday, the formalities of diplomacy will conceal a far more consequential negotiation. At stake is not simply bilateral cooperation, but Japan’s ability to operate within an increasingly transactional alliance framework—one in which economic access is implicitly tied to military contribution. For Tokyo, whose export-driven economy depends heavily on the U.S. market, meeting this “security-for-trade” expectation has become an urgent strategic necessity.
The Iran situation will of course be front and center in the talks. Military operations, now in their third week, have effectively closed the Strait of Hormuz, a chokepoint through which roughly 20 percent of global oil and liquefied natural gas flows. For Japan, which imports more than 90 percent of its crude oil from the region, the disruption represents a severe and immediate vulnerability.
Yet the situation also presents a strategic paradox. While the short-term impact is destabilizing, the ongoing military operations are achieving core objectives. By degrading hostile infrastructure and weakening proxy networks, the U.S. and Israel are eliminating the structural sources of instability that have long threatened global energy transit. From this perspective, current disruptions are the cost of producing a more secure and predictable energy environment in the future—an outcome that would disproportionately benefit energy-importing economies such as Japan. Moreover, Japan’s extensive strategic petroleum reserve, built in response to the oil shocks of the 1970s, offer some, albeit temporary, relief.
