Takaichi’s Calculated Gamble at the Trump Summit Amid the Iran Crisis
Trumps said that Tokyo is “really stepping up to the plate” on Iran – “unlike NATO.”

When Japanese Prime Minister Takaichi Sanae arrived at the White House on March 19, the visit carried a palpable sense of political risk in Tokyo. With tensions escalating in the Israel-U.S. conflict with Iran, there were widespread concerns that Takaichi was, in effect, “flying into the fire” – exposing herself to potential U.S. demands for military contributions in the Middle East.
In the end, Takaichi appears to have navigated one of the most challenging diplomatic moments of her premiership – maintaining alliance unity while avoiding explicit commitments.
The meeting with U.S. President Donald Trump was not initially intended to focus on the Middle East. Tokyo had pushed for an early summit ahead of a China-U.S. leaders’ meeting planned for April, hoping to hedge against the risk of a China-U.S. “grand bargain” that might sideline Japanese interests.
That calculation unraveled when Trump postponed his visit to China by more than a month, reportedly in part due to the unexpectedly prolonged conflict with Iran. Instead of shaping China policy, the Japan-U.S. summit was overtaken by crisis management in the Persian Gulf.
At the center of the discussion was the Strait of Hormuz, where Iran’s actions have effectively disrupted maritime traffic – and where Japan’s vulnerabilities are acute. Japan depends on the Middle East for about 95 percent of its crude oil imports, with about 70-75 percent transiting the Strait of Hormuz. Globally, the waterway carries around one-fifth of the world’s oil supply, making any sustained disruption a matter of physical supply risk, not just price volatility.
Trump underscored this bluntly, framing Japan’s dependence as a compelling reason for Tokyo to contribute more to securing the route. Throughout the meeting, Trump repeatedly called on Japan to “step up,” signaling expectations for greater burden-sharing.
“We’ve had tremendous support from and a relationship with Japan,” Trump said. “I believe that, based on statements that were given to us … they are really stepping up to the plate. Unlike NATO.”
His remarks suggested that Tokyo is more politically aligned with U.S. expectations than some European allies.
Yet what “stepping up” entails remains deliberately ambiguous.
No specific requests were publicly confirmed. However, U.S. concerns over mine warfare capabilities have fueled speculation that Washington may have raised the possibility of Japanese participation in mine countermeasure operations.
U.S. Treasury Secretary Scott Bessent said on the morning of March 19 that Japan would be expected to ensure the security of its energy supplies.
Speaking to Fox Business Network, Bessent noted that Japan’s navy possesses some of the world’s most advanced minesweeping and mine-detection capabilities.
While it remains unclear whether Iran has actually deployed naval mines, the possibility has become a growing concern. Against this backdrop, it is plausible that Washington raised the issue of dispatching Japanese mine countermeasure assets during the summit.
Such expectations are shaped in part by concerns over U.S. capabilities. The U.S. Navy’s dedicated minesweeping capacity has diminished recently,........
