Investors, finally having some good news, seemed to largely ignore thorny questions about the details of the trade deal, let alone the tenuous position of Prime Minister Shigeru Ishiba following a recent election setback.

Japanese Prime Minister Shigeru Ishiba has vowed to remain in power to oversee the implementation of a new Japan-U.S. tariff agreement.

As President Donald Trump’s tariffs add to a sense of uncertainty in Japan, the Sanseito party and its leader Sohei Kamiya made gains on a “Japanese first” platform.

Shigeru Ishiba denied he had decided to quit after a source and media reports said he planned to announce his resignation to take responsibility for a bruising upper house election defeat.

As part of a trade deal reached this week, Japan agreed to invest $550 billion in projects across strategic U.S. industries, including energy, semiconductor manufacturing and shipbuilding. The White House said Trump would have final say over where the money goes and that the U.S. would keep 90% of profits on any investments.

The reports come after Trump announced a trade deal with Japan, and days after Ishiba’s governing coalition lost its majority in the country’s upper house.

Japanese Prime Minister Shigeru Ishiba said on Thursday U.S. President Donald Trump's views on some tariff-related issues may be based on misunderstanding or misinformation, as a pause on a 24% reciprocal tariff on imports from Japan expires next week.
