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

average ended lower 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.

The Nikkei index fell 1.22% to close at 37,965.1,

having ended the previous trading session at its highest point

in more than two weeks. It rose 2.17% over the week.

The broader Topix fell 0.37% to 2,801.57 and rose

2.41% 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 Nissan Motor ( NSANF ) and Honda Motor ( HMC )

slipping 3.13% and 1.87%, respectively. Toyota Motor ( TM )

erased early loss to end 1.26% higher.

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 3.61% and 4.76% respectively, to drag on

the Nikkei the most.

Bucking the trend, drugmakers rose, with Otsuka Holdings ( OTSKY )

jumping 6.82% to provide the biggest support for the

Nikkei.

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

Exchange's prime market, 57% rose, 38% fell and 3% were flat.
