WASHINGTON, Sept 5, 2025 (BSS/AFP) - US President Donald Trump signed an order Thursday to lower tariffs on Japanese autos, as Washington moves to implement a trade pact negotiated with Tokyo.

Japanese autos will face a 15 percent tariff instead of the current 27.5 percent, while the level for many other goods will similarly be capped at 15 percent, according to the text of the executive order published by the White House.

The outcome marks a win for Japan, after Tokyo's tariff envoy headed to Washington on Thursday to press Trump to sign the document for the changes -- weeks after both sides announced their agreement.

Top government spokesman Yoshimasa Hayashi said Japan welcomed the executive order, which marked "the steadfast implementation" of the deal.

While the two countries had initially unveiled a trade pact in late July, they appeared to diverge in its details.

When Trump in early August implemented higher tariffs on Japan -- as part of a flurry targeting dozens of economies -- its 15 percent rate stacked on existing levels for many products.

Japan's tariffs envoy Ryosei Akazawa had earlier told reporters that Washington was expected to revise the rule.

According to the new order, the 15 percent cap for many products will apply retroactively to goods shipped from August 7 -- the date that the higher duties on dozens of economies took effect.

The modifications are to be made within seven days of the rule being published on the Federal Register.

- 'Still cause damage'-

Apart from Washington's country-specific tariff levels, Trump has also imposed separate sector-specific tariff rates, including a 25 percent duty on autos and parts.

This, coupled with an existing 2.5 percent tariff the Japanese auto industry faced, took the overall level to 27.5 percent.

The hefty duties had marked a heavy blow to Japan and its crucial auto sector, which accounts for around eight percent of the country's jobs.

Japan's deal wins it a similar reprieve to the European Union, which also has a 15 percent maximum tariff on many products.

But speaking in Washington, Akazawa told Japanese media Friday that the 15 percent tariff would "still cause damage to our nation's industries".

"The Japanese government will take swift and necessary measures, like financing assistance," he added.

Akazawa was also expected to engage in further discussions during his US trip about Trump's assertion that Japan would make investments worth $550 billion in the United States.

According to Trump's order, the investments "will be selected by the United States Government," but the document did not go into detail.

Ishiba said Friday that Tokyo had sent a letter to Washington saying "we would like to build a golden age for Japan and the United States together with President Trump, and that we would like to invite him to Japan".

Trump has said the United States will keep 90 percent of the profits from the investments, which Japan has said will mostly consist of loans and loan guarantees.

Akazawa had cancelled an earlier visit after Washington said that it was considering including a reduction in Japanese tariffs on agricultural products in the presidential order, the Nikkei business daily reported.

Trump has long pressed Japan to import more American rice.
