Japan’s top trade negotiator and Minister of State for Economic Revitalization, Akimasa Akazawa, said the cuts on automobile tariffs could take time to be effected.

Japan said on Tuesday the trade agreement it struck with the U.S. cleared uncertainties on U.S. trade policies but continued attention needs to be given to risks of those policies putting downward pressure on the Japanese economy.

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