Tokyo shares opened 0.30 per cent lower on Thursday after New York stocks sank amid worries over a Greek debt deal. The Nikkei 225 index at the Tokyo Stock Exchange, which closed at its highest point since August 5 on Wednesday thanks to a weaker yen, opened down 27.96 points at 9,232.38.

“The market may take a break after reaching the psychologically important 9,250 mark (on Wednesday),” said Daiwa Securities senior market analyst Yumi Nishimura.
