Most Asian markets except Australia advanced in the week, taking cues from a string of positive US data and a weakening yen. Japan's Nikkei breached the psychologically important 15,000 mark and closed the week's trade with a 2.5% gain, at 15,138.1.
A tumbling yen that hit a 4-1/2 year low at the beginning of the week boosted Japanese stocks, which shot up to a 5-1/2 year high mid-week as exporters' stocks rallied on the back of a weakening yen.
Other Asian stocks opened lower but posted gains towards the close of the week, owing to an unexpected rise in US retail sales and better-than-expected GDP data from Japan.
The Kospi rose 2% during the week and closed at 1,986.8. The Shanghai Composite moved up 1.5% to close at 2,282.8. The Hang Seng gained 0.4% and ended at 23,082.7.
But the S&P/ASX 200 lost 0.4% to finish off at 5,180.8. The benchmark Australian index posted its first weekly loss in four weeks, partly owing to a weakening Australian dollar.
Reports from the US about the Federal Reserve possibly rolling back its bond-buying programme by this summer pushed the dollar to an almost three-year high. The greenback also hit a new high versus the yen, breaking the 103 yen level, its highest since October 2008.
