TOKYO, May 30 (Reuters) - Japan's Nikkei share price

average fell on Friday, weighed down by uncertainty surrounding

a court battle about U.S. President Donald Trump's tariffs as

well as a stronger yen which hurt exporters.

At 0134 GMT, the Nikkei index was down 1.4% at

37,880.58. It ended the previous trading session at its highest

point in over two weeks and is on course for a 1.9% weekly gain.

The broader Topix fell 0.85% to 2,788.17 and is set

for a rise of 1.9% for the week.

"Japanese shares rose yesterday on expectations that the

impact of Trump's tariffs on the global economy would be eased,

but that positive mood was erased overnight," said market

analyst Shuutarou Yasuda at Tokai Tokyo Intelligence Laboratory.

A federal appeals court temporarily reinstated the most

sweeping of Trump's tariffs on Thursday, a day after a trade

court ruled that the president had exceeded his authority in

imposing the duties and ordered an immediate block on them.

The U.S. dollar fell following the news, pushing the yen as

high as 143.45 on Friday.

Strong inflation data on Friday for Japan's capital also

helped the yen to strengthen, strategists said.

Automakers fell, with Toyota Motor ( TM ) and Honda Motor ( HMC )

slipping 1.87% and 2% respectively.

A stronger yen typically weighs on exporter shares by

reducing the value of overseas earnings when converted back into

Japanese currency.

Chip-related shares fell, with Advantest ( ADTTF ) and Tokyo

Electron ( TOELF ) down 3.7% and 3.5% respectively.

Uniqlo-brand owner and index heavyweight Fast Retailing ( FRCOF )

fell 2.35% to drag on the Nikkei the most.

Bucking the trend, drugmakers rose, with Otsuka and

Eisai ( ESALF ) rising 2.59% and 2.77% respectively to offer the

biggest support for the Nikkei.

Of more than 1,600 stocks trading on the Tokyo Stock

Exchange's prime market, 38% rose, 56% fell and 5% were flat.
