TOKYO, July 30 (Reuters) - Japan's Nikkei share average

ended morning trade flat on Wednesday after spending most of the

session slightly lower, as investors braced for a three-day

period that will see policy decisions from the Federal Reserve

and Bank of Japan, followed by U.S. President Donald Trump's

deadline for trade deals.

The Nikkei entered the midday break little changed

at 40,682.14. Of the index's 225 components, 148 rose and 77

fell.

The broader Topix rose 0.35%.

The Fed sets rates on Wednesday, and while policymakers are

widely expected to stand pat, investors will be watching closely

for signs that an interest rate cut may be on the way later this

year.

Similarly, the BOJ is seen keeping policy steady on

Thursday, but markets will search for clues on when the central

bank is likely to resume rate hikes.

On Friday, most U.S. trade partners that have not agreed

deals with Washington will receive higher tariff rates.

"There are still a lot of uncertainties over tariffs, and

that's going to limit the upside for stocks," said Maki Sawada,

an equities strategist at Nomura Securities.

As a result, "there's no particular sense of direction" in

Japanese stock trading currently, she said.

Airline ANA Holdings ( ALNPF ) fell 3.8% to be the Nikkei's

biggest percentage decliner following its earnings report after

the market closed on Tuesday.

Earnings also weighed on chip-testing equipment maker

Advantest ( ADTTF ), which slipped 1.8%.

Sumitomo Pharma ( DNPUF ) surged nearly 16% to be the biggest

percentage gainer.
