Tokyo, Oct 6 Japanese stocks rose more than one percent in Wednesday morning trading, buoyed by strong gains on Wall Street and monetary easing steps announced by the Bank of Japan.

The benchmark Nikkei 225 Stock Average added 122.58 points, or 1.29 percent, to trade at 9,641.34 while the broader Topix index was up 6.41 points, or 0.77 percent, at 839.05.

The Bank of Japan decided Tuesday to revive zero-interest policy and to establish a five-trillion-yen ($60 billion) fund to buy financial assets to address the yen's rise and the nation's slowing economic recovery.

But investors remained concerned about the strenghtening yen after the dollar briefly dipped into the upper-82-yen range overnight in New York.

US stocks were buoyed Tuesday by a better-than-expected report on the US service sector and the decision made by Japan's central bank. The private Institute for Supply Management reported that its index of service industries was showing robust improvements.

On currency markets at 9 a.m. (0000 GMT), the dollar traded at 83.16-17 yen, down from Tuesday's 5 p.m. quote of 83.50-51 yen.

The euro traded at $1.3852-3853, up from $1.3768-3769 Tuesday, and at 115.20-21 yen, up from 114.96-115.00 yen. (DPA)
