Japanese stocks extended gains Tuesday for the second consecutive trading day on overnight rises on Wall Street and eased concerns about the eurozone debt crisis.
A system failure halted derivatives trading on the Tokyo Stock Exchange for one and a half hours in the morning, but the suspension appeared to have little impact on other trading.
The benchmark Nikkei 225 Stock Average gained 77.02 points, or 0.88 per cent, to end at 8,803.31 while the broader-based Topix index was up 7.97 points, or 1.08 per cent, at 743.7.
Export-oriented issues traded broadly higher. Shares in construction machinery maker Komatsu Ltd jumped 2 per cent, Canon Inc climbed 0.82 per cent, Sony Corp gained 0.78 per cent, Nissan Motor Co put on 1.86 per cent, Toyota Motor Corp added 1.43 per cent and Honda Motor Co was up 1.17 per cent.
The bourse said it had not found specific causes for the problem that stopped trading in derivatives that included Topix-linked futures and long-term government bond futures.
Trading resumed at 10:55 am (03:55 SA time) after a suspension that began at 9:18 am, the exchange said.
On Monday, the Dow Jones Industrial Average edged up 0.16 per cent as the German government came out in favour of a European Central Bank plan to buy the bonds of troubled eurozone countries announced last week.
