TOKYO (Reuters) -Japan's leading trade negotiator said on Tuesday that the trade deal Tokyo agreed with the United States last week guarantees Japan will always receive the lowest tariff rate on chips and pharmaceuticals of all the pacts negotiated by Washington.

The new U.S.-Japan trade deal lowers tariffs and strengthens economic ties, helping challenge China's regional aggression and instability.

Japan’s central bank policymakers are expected to keep rates on hold this week, despite the trade deal with the U.S. relieving some uncertainty over tariffs and strengthening the case for tighter policy.

Analysts at Bank of America said that the Japan deal "looks like a reasonable blueprint" for other auto-exporting countries like South Korea.

Japan's government said on Friday that profits from a $550 billion investment package agreed in this week's tariff deal with the U.S. would be split between Japan and the U.S. according to the degree of contributions by each side.

The US and EU are racing to lock in the final details of their major new trade deal before Friday's deadline. Critics say its a rushed fix, with German Chancellor Friedrich Merz calling the outcome unsatisfying and France’s Bayrou dubbing the EU’s "submission" a "dark day.

Japan is playing down the risks from its deal after the White House said the U.S. would direct $550 billion in investments by Japan and keep 90% of the profit.
