TOKYO — Japanese Prime Minister Sanae Takaichi said Tuesday that President Donald Trump had told her not to “hesitate to bother me” when Japan and the United States needed each other. The high-stakes, acrimonious Trump-Takaichi call followed a day after the telephone conversation between Trump and Chinese President Xi Jinping over the future of the island — underscoring how Taiwan is serving as an irritant to great-power ties across Asia, Nov. 25, 2025.
Here’s why the Trump Takaichi call matters for Taiwan and the region
Takaichi said the call, which lasted about 25 minutes, came at Trump’s request and was part of efforts to reassure Tokyo that the two leaders are still “very good friends,” despite a simmering feud with Beijing over her recent remarks on Taiwan. Trump briefed her on the state of U.S.-China relations and told Haley he wanted her to keep in close touch, Reuters reported in a detailed account of the call.
The Trump Takaichi call came after Trump held a separate talk with Xi, who framed Taiwan’s “return” to China as part of the post-World War II order and pushed his sovereignty claims over the self-ruled island. A social media summary of Trump’s call with Xi by Reuters said Trump described ties with Beijing as “extremely strong,” mentioned trade and rare-earth discussions, but did not include a reference to Taiwan.
Takaichi has been at the eye of the latest storm after telling parliament this month that a hypothetical Chinese attack on democratically governed Taiwan could amount to a “survival-threatening situation” for Japan, potentially bringing its security laws into play. Beijing demands that she withdraw the comments, summons Japan’s ambassador, warns Tokyo not to “interfere” in the Taiwan Strait, and urges Chinese tourists to boycott Japan — actions that Japanese officials worry could harden into a more lasting diplomatic chill.
China has also condemned Japan’s planned deployment of more missile units on its far-flung southwestern islands, some within striking distance of Taiwan, as a deliberate bid to stoke regional tension. Such islands, including Yonaguni, are a little over 100 kilometers from Taiwan and have long been held up as potential flashpoints; a feature in the Guardian in 2024 described residents who were already grappling with the creeping militarization of their home as Tokyo builds out bases and air defenses.
For Tokyo, Trump’s restraint over the Japan-China tussle has been as significant as his warm words for Xi amid mounting fears that U.S. support for Taiwan could be set aside in the balance of trade and grand strategic deals with Beijing. Analysts cited by Japanese media outlets have cautioned that the Trump administration might, in a worst-case scenario, sacrifice Taiwan’s security interests to seek economic concessions from China — an outcome that would concern hawks in Japan and advocates of Taiwan independence alike.
Tuesday’s Trump-Takaichi call seemed aimed, at least in part, to lower those anxieties. During the session, Trump emphasized the importance of the U.S.-Japan alliance and told Takaichi to call him if there were an issue, gestures that Japanese officials interpreted as a move to reassure a close ally as Washington navigates its own tenuous relationship with Beijing. But so far, the absence of explicit public backing for her stance on Taiwan raises questions about how far the White House is willing to go if tensions erupt.
The discussion also falls into a pattern of very early outreach between the two leaders. In their first phone call since she assumed office last month, Takaichi told Trump that strengthening the alliance was her government’s “top priority,” according to a Reuters dispatch on that October conversation. Trump, for his part, hailed Japan as an indispensable partner in U.S. strategy toward China and the broader Indo-Pacific — highlighting not only the critical security ties between the two capitals but also Tokyo’s role as a bridge between continents to ensure “peace and stability in this region.”
Beyond the symbolism of the Trump-Takaichi call, policymakers in Tokyo and Washington now face the thornier challenge of coordinating their Taiwan messaging without inviting further Chinese retaliation. As China has ratcheted up military and rhetorical pressure and Japan has increased missile deployments and defense spending, turning the region into a new hotbed of nuclear competition, that delicate balance between deterrence and escalation in the western Pacific is getting harder to preserve.
