# Takaichi Seeks a Call With Trump After His Wartime Remarks on China

Tokyo's concern is that Beijing will use the Washington summit to cast Japan, not China, as the revisionist power in Asia.

Japanese Prime Minister Sanae Takaichi is believed to be seeking a telephone call with Trump to address Tokyo's concerns after the Washington summit, [The Japan Times reported](https://www.japantimes.co.jp/news/2026/09/26/japan/politics/japan-trump-xi-summit/). The worry in Tokyo is that Beijing will use the meeting to reinforce a narrative in which Japan is the destabilizing actor in East Asia.

The trigger was Trump's invocation of the American alliance with China during the Second World War, references that [the South China Morning Post reported](https://www.scmp.com/news/china/diplomacy/article/3368878/will-trump-xi-wartime-ally-nostalgia-prompt-japanese-rethink-china-ties?utm_source=rss_feed) were received in Tokyo as a serious departure from recent American framing. Chinese officials have long grounded their regional claims in wartime history, and an American president adopting that vocabulary, even casually, changes the diplomatic terms that shape Japan's security position.

Japanese officials have not disputed the substance of the alliance, and Washington has not announced any change to its commitments. The question Tokyo is asking is narrower and more practical: whether an administration that relies heavily on personal rapport with foreign leaders will treat Japanese security priorities as one input among many when negotiating with Beijing on trade and technology.

For markets the effect runs through Japanese defense procurement and the yen. A government that doubts the durability of an external guarantee spends more on its own capabilities and looks for partners beyond its treaty ally, both of which have fiscal consequences for a state already normalizing monetary policy after decades of accommodation.

## What this means

The mechanism is alliance credibility priced into fiscal and defense decisions. If Tokyo concludes American backing is contingent on the state of Washington's China negotiations, the response is higher domestic defense spending, faster domestic weapons production and broader security partnerships, all of which add to Japanese government borrowing at a moment when the Bank of Japan is raising the cost of that borrowing. Those exposed are Japanese government bond holders, Japanese defense contractors on the gaining side, and American suppliers who lose share as Tokyo builds its own capacity. Xi wants exactly this ambiguity and achieved it at low cost. Takaichi can seek reassurance but cannot compel a public restatement. The likelier outcome over the coming months is a reassuring call followed by larger Japanese defense budget requests rather than any visible rupture, conditional on no incident in the East China Sea forcing the issue. A joint American-Japanese statement restating specific treaty obligations would show that Tokyo secured more than a symbolic gesture.

## What to watch

- Whether the Takaichi-Trump call happens and whether the readout names specific treaty commitments.
- Japan's next defense budget request, the practical measure of how much reassurance Tokyo believes it received.
- Chinese activity around the Senkaku Islands, which would test the alliance language immediately rather than rhetorically.
