Markets in Asia tumbled overnight, with China's domestic market selling off sharply, amid ongoing concerns over the recovery in the west.
Following a warning from Fed chairman Ben Bernanke that the US is not out of the woods yet, shares in major Asian markets fell overnight.
The Nikkei was down 0.71%, at 10,182.57 points, while Hong Kong's Hang Seng Index dropped 1% to 20,835.87.
Meanwhile China's Shanghai Shenzhen CSI 300 Index fell more than 2%, to 2,487.67.
US shares had earlier ended the session lower, with both the Dow and the S&P 500 off after Bernanke's latest comments.
The Fed chairman warned investors "it's far too early to declare victory".
His comments come despite a resurgence in growth in the US, where GDP growth has climbed above 2%.
However, the country's jobless rate remains a major issue, and Bernanke reportedly said policymakers have not ruled out further options to boost growth.
US shares sold-off following the comments, with the Dow off 0.33% at 13,197.73, and the S&P 500 down 0.3% at 1,412.52.
