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.

Some foreign firms are taking a similar stance in response to Mr Trump’s new levies. In April Ferrari added up to 10% to the price of its cars. Britain’s Ineos said it would charge more for its Grenadier off‑roader. Canon, a camera-maker, has warned dealers to brace for price increases.

On his own terms, it could now be said that the aggressive approach by the US President is yielding tangible results.

President Donald Trump is set to meet with European Commission chief Ursula von der Leyen in Scotland to discuss trade. Both sides are seeking an agreement on tariff rates.

Japan's top tariff negotiator, Ryosei Akazawa, met with U.S. President Donald Trump at the White House on Tuesday, the Asahi newspaper reported on Wednesday.

Japan's embattled prime minister Shigeru Ishiba, fresh off a crushing defeat in upper house elections over the weekend, will not be in a position of strength to negotiate a favorable trade deal with the U.S., analysts said.
