AlHijjah 28, 1432, Nov 24, 2011, SPA -- Tokyo shares on Thursday fell to their lowest point since March 2009 on renewed fears over the debt crisis in the eurozone, according to dpa. The benchmark Nikkei 225 Stock Average fell 1.8 per cent, or 149.56 points, to close at 8,165.18. The broader Topix index was down 1.63 per cent, or 11.71 points, at 706.08. Japanese shares followed a fall on US markets overnight as investors were concerned by recent developments in the eurozone debt crisis. The European Central Bank stepped in Wednesday to buy government bonds after the yield on 10-year bonds in Italy and Spain inched up towards the key 7-per-cent mark, the point where economists said borrowing becomes unsustainable. Sales on German 10-year bonds also fell short by about 35 per cent, raising the prospect of the debt crisis spreading to Germany. On currency markets, the dollar traded at 77.14-15 yen at 3 pm (0600 GMT) Thursday, up from 76.98-99 yen late Tuesday. The euro was quoted at 103.04-07 yen, down from 104.12-16 yen, and at 1.3358-60 dollars, down from 1.3525-26 dollars. Japan's markets were closed Wednesday for a public holiday.
