HONG KONG, March 12 (Reuters) - Japanese shares fell 1 percent on Thursday and other Asian markets were on the defensive as investors viewed rare gains this week as overdone in light of a shaky global economy and financial system.
The yen rose against the U.S. dollar after revised figures in Japan showed the economy had contracted slightly less in the fourth quarter than previously reported, while the New Zealand dollar found some support on a central bank rate cut that was smaller than some had expected.
Oil prices bounced from two days of sharp losses though the focus remains on a meeting of OPEC this week and uncertainty about whether the oil producers will cut production or not. [
]Thursday's stock trading reflected a trend this year of steep declines followed by bursts of small gains that quickly fizzle as investors focus on the bleak global economy and uncertainty about how to cleanse the banking system of toxic debt.
"Market falls were in store for us as it's hard to expect gains two days in a row, considering current market conditions," said Fumiyuki Nakanishi, manager at SMBC Friend Securities in Japan.
