U.S. exports of goods to Japan increased by about $0.73 billion from Q1 2025 to Q4 2025, rising from $19.95 billion to $20.78 billion. That’s roughly a 4.2% gain over that span.

What that means

  • Start of Trump’s 2025 term: Q1 2025 exports to Japan were $19.95 billion.
  • Latest 2025 quarter available: Q4 2025 exports were $20.78 billion.
  • Dollar change: +$0.83 billion.
  • Percent change: about +4.2%.

Broader context

Even though exports to Japan rose over 2025, several reports say Trump-era tariffs pressured trade patterns and hurt Japan’s exports to the U.S., especially autos and machinery. At the same time, Japan’s overall export value still rose in 2025, which shows the effect was mixed rather than uniform across all trade flows.

One caveat

If you meant calendar-year total exports rather than quarterly exports, the best available figure here still points to a 2025 rise in Japan’s overall exports, but the quarter-to-quarter U.S.-to-Japan number above is the cleanest dollar change tied to “since Trump took office”.
