Japanese shares rallied after media reports suggested that the Japanese government is likely to nominate Haruhiko Kuroda, present governor for Asia Development Bank and an aggressive advocate of monetary easing policy, as the next BOJ governor.
"The news of Kuroda (as BOJ nominee) appears to be taken positively by the market, but I think signs of progress towards TPP are vital as it shows Abe is taking leadership in pushing structural reforms, with the TPP being a vital tool to boosting growth," Tetsuro Ii, the chief executive of Commons Asset Management, told Reuters.
However, the upward move was limited after a report showed that Chinese factory activity grew at a slower rate in February. The HSBC Flash Purchasing Managers' Index (PMI), a measure of the nation-wide manufacturing, declined to a four-month low of 50.4 in February from January's final reading of 52.3.
Meanwhile, market participants await the final outcome of the Italian elections as the results are set to have a major impact on euro zone's financial recovery efforts. Opinion polls have suggested the centre-left coalition led by Pier Luigi Bersani could secure a narrow victory.
