The president of the Tokyo Stock Exchange Group Inc. pledged Monday that the company would continue opening Japan's key equities market after Friday's earthquake and tsunami. "Considering that stocks are frequently being traded across borders, it is our responsibility to offer as many trading opportunities as possible so the mother market of Japanese stocks can form appropriate stock prices reflecting supply and demand of many investors," TSE President Atsushi Saito said.

Osaka Securities Exchange Co. President Michio Yoneda also issued a statement saying it will open the bourse as usual, while calling on investors to "watch situations calmly."
