Japan's Nikkei stock index shed about 0.5% as the yen pulled off its lows. Investors also locked in gains after the index soared to an 11-1/2 week high following a report the Bank of Japan will consider another easing step at its two-day policy review that ends on Wednesday.

But some investors still believe the central bank might opt to hold steady as it assesses the impact of its negative interest rate policy unveiled on Jan. 29. A semi-annual report on the

A Reuters poll showed on Friday showed that economists expect the Fed to stand pat and then deliver a rate hike in June, and follow up with another by the end of this year.
