Tokyo - Tokyo shares opened lower on Wednesday after two days of gains, weighed down by lower oil prices and the yen's uptick on weak US consumer confidence data.
"The rhythmic rise in Japanese stocks has to take a breather," said Chihiro Ohta, a Tokyo-based senior strategist at SMBC Nikko Securities.
"The weaker US consumer sentiment data gives a reason for the yen to strengthen, weighing on stocks," he told Bloomberg News.
A stronger yen erodes Japanese exporters' profitability.
