Tokyo stocks ended flat Friday on late profit-taking as investors await the release of key US jobs data.
The Nikkei-225 index edged down 0.05 percent, or 8.11 points, to 15,063.77, while the Topix index of all first-section shares slipped 0.07 percent, or 0.88 points, to 1,215.89.
The headline Nikkei index gained ground in morning trading, adding to a 0.84 percent gain Thursday but some investors opted to cash in, while others held back to until the US non-farm payrolls data later in the day, dealers said.
"Players refrained from trading actively today following the recent rise and ahead of US jobs data," said Shunichi Umeda, a broker at Tokai Tokyo Securities. "Consensus is that the figures will show a positive sign."
The report will give a clearer idea about the US recovery than recent readings, which were skewed by severe winter weather at the turn of the year.
While a strong figure will be welcomed, there are fears that the numbers could be too good for the Federal Reserve's liking.
Norihiro Fujito, senior investment strategist at Mitsubishi UFJ Morgan Stanley Securities, said: "Solid jobs data is welcome, but numbers too robust may spark fears that the Fed may actually accelerate stimulus tapering."
That could result in "another roiling effect", he said.
The US Federal Reserve's decision to start winding down its stimulus programme and fears of capital flight triggered sell-offs in emerging markets earlier this year.
On forex markets the dollar bought 103.84 yen, against 103.94 yen in New York Thursday.
In stocks trading, Sony rose 0.15 percent to 1,994 yen, Toyota fell 0.82 percent to 5,792 yen and Nissan rose 0.85 percent to 947 yen.
