Japan's Nikkei index ended off session highs on Friday after surging past the 13,000 mark as investors cheered the Bank of Japan's (BOJ) monetary onslaught of $1.4 trillion in stimulus. However, the rest of Asia's stock markets tumbled to multi-month lows on caution ahead of U.S. payrolls data.
The yen came off its earlier three-and-a-half year low of 96.9 per dollar to strengthen 0.9 percent while yields on 10-year Japanese government bonds rose 0.615 percent after sinking to an earlier record low of 0.315 percent.
While some experts hail the BOJ's bold stimulus program as a new chapter for Tokyo risk assets, billionaire investor George Soros expressed his skepticism.
"What Japan is doing is actually quite dangerous because they are doing it after 25 years of just simply accumulating deficits and not getting the economy going," he said. "If the yen starts to fall, which it has done, and people in Japan realize that it is liable to continue, and want to put their money abroad, then the fall may become like an avalanche," he added.
