TOKYO, March 4 (Reuters) - Japan's Nikkei share average

fell more than 1% in early trade on Tuesday, dragged by

overnight Wall Street declines and a stronger yen, with U.S.

tariffs on Canada and Mexico to take effect as planned later in

the day.

The Nikkei dropped 1.3% to 37,287.73, as of 0015

GMT, while the broader Topix was down 0.6%.

Wall Street's main stock indexes closed sharply lower on

Monday after U.S. President Donald Trump announced the start of

25% tariffs on Canada and Mexico from Tuesday, with the S&P 500

posting its biggest daily decline since December 18.

Trump also reaffirmed that he will increase tariffs on all

Chinese imports to 20% from the previous 10% levy.

Meanwhile, the yen appreciated against the U.S. dollar as

the greenback slid, knocking down exporters shares and further

dragging investor sentiment.

The Nikkei's biggest decliners were Furukawa Electric

Ltd, down 8.9%, followed by Advantest Corp ( ADTTF )

losing 7.9% and Fujikura Ltd ( FKURF ), dropping 7.2%.
