TOKYO (Kyodo) -- Tokyo stocks ended slightly higher after choppy trading Tuesday, as optimism over a potential delay in U.S. tariffs faded after new U.S. President Donald Trump suggested they could soon be imposed on Mexico and Canada.

The 225-issue Nikkei Stock Average ended up 125.48 points, or 0.32 percent, from Monday at 39,027.98. The broader Topix index finished 2.23 points, or 0.08 percent, higher at 2,713.50.

On the top-tier Prime Market, gainers were led by miscellaneous product, textile and apparel, and rubber product shares.

The U.S. dollar hit a one-month low in the upper 154 yen zone in Tokyo, as U.S. long-term Treasury yields fell on eased concerns over inflation following a lack of tariff announcements during Trump's inauguration.

But it later briefly bounced back to the lower 156 yen range after Trump suggested that the United States could impose 25 percent tariffs on Mexico and Canada from next month, dealers said.

At 5 p.m., the dollar fetched 155.67-70 yen compared with 155.67-71 at 4 p.m. in London and 155.98-156.00 yen in Tokyo at 5 p.m. Monday.

The euro was quoted at $1.0372-0374 and 161.48-52 yen against $1.0317-0318 and 160.93-97 yen in Tokyo late Monday afternoon. U.S. financial markets were closed Monday for a public holiday.

The yield on the benchmark 10-year Japanese government bond fell 0.005 percentage point from Monday's close to 1.185 percent, tracking a decline in long-term U.S. Treasury yields.

Stocks started higher as investors were relieved by Trump refraining from imposing tariffs on his first day in office. But they turned downward following his remarks on Mexico and Canada, as concerns took hold that export-oriented firms may be adversely impacted by the new trade measure, analysts said.

Movements in both stock and currency markets for the day were largely influenced by the new U.S. president, as "investors reacted with both optimism and concern in line with his remarks," said Yutaka Miura, senior technical analyst at Mizuho Securities Co.

Trump has pledged to impose 60 percent or higher tariffs on imports from China and a "universal" duty of up to 20 percent on everything else entering the world's largest economy.

But a lack of further clues on U.S. tariffs beyond its two neighboring countries led to muted trading in the afternoon, with investors adopting a wait-and-see stance ahead of U.S. markets opening later in the day after a long weekend, Miura said.
