TOKYO, Sept 5 (Reuters) - Japan's Nikkei share average

rose on Friday after U.S. President Donald Trump signed an order

to lower tariffs on Japanese automobile shipments and other

products.

The Nikkei rose 0.73% to 42,890.85 by the midday

break.

The index crossed the 43,000 level for the first time since

August 25 soon after the opening, but it gave up some gains as

investors sold stocks to book profits, strategists said.

The broader Topix rose 0.35% to 3,091.08.

"Investors welcomed the news about Trump's order to lower

tariffs on Japan's exports, but the gains at the open were too

much," said Shuji Hosoi, senior strategist at Daiwa Securities.

Toyota Motor ( TM ) and Honda Motor ( HMC ) rose 0.5% and

0.75%, respectively.

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

Electron ( TOELF ) gaining 2.54% and 0.07%, respectively.

Daiwa Securities' Hosoi said the Nikkei could touch the

44,000 level next week, as sentiment was boosted by the lower

tariffs on Japanese products.

The index is also seen rebounding as it fell below its

25-day moving average earlier this week, Hosoi said.

The Nikkei hit a record high in August and traded above the

25-day moving average, a key support level in technical

analysis, for most of the month.

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

Exchange's prime market, 57% rose and 37% fell, and 4% traded

flat.
