Takaichi to highlight Japanese investment in US talks with Trump
Japanese Prime Minister Sanae Takaichi plans to stress Japan's commitment to massive US investments and their contributions to the American economy in upcoming talks with President Trump, Nikkei Asia reported two days ago. For Japanese companies operating in the US, the continued political emphasis on investment pledges signals ongoing governmental support for new projects.

Japanese food makers step up US investment
Jiji Press reported on September 21 that Japanese food manufacturers are making aggressive investments in the US, spurred by the growing penetration of Japanese food and rising inbound tourism. The report includes a photo of Kikkoman's third US plant in Jefferson, Wisconsin, photographed September 18. Food processing is a quieter but steadily expanding frontier of Japanese corporate activity beyond autos and semiconductors.

Regulation & market context
Four companies topped Japan's market cap ranking this year — first since 1980
Seoul Economic Daily reported on September 22 that four companies — Toyota, Kioxia, SoftBank and Mitsubishi UFJ — held the top spot in Japan's market cap ranking within a single year, the first such shuffle since 1980. The reshuffle, driven largely by AI-related equity demand, reflects the changing profile of Japan's largest companies that anchor cross-border investment into the US.
On the radar
- Officials previously indicated progress on the $550 billion investment pact with AI and semiconductor projects central to its next phase; watch for new project selections
- The proposed ~$19 billion logic semiconductor facility, reportedly to be operated by GlobalFoundries under the investment pact, remains unconfirmed — worth monitoring for official recognition
- Trade Minister Ryosei Akazawa's earlier statements on progress of the $550 billion initiative suggest continued ministerial-level announcements
By the numbers
- $550 billion — the Japan–US investment initiative that Takaichi will highlight in talks with Trump
- ~$19 billion — reported size of the semiconductor plant under discussion under the investment pact
- 4 — number of companies to top Japan's market cap ranking within one year, the first such shuffle since 1980
