The Japanese yen traded at 114.17 per dollar following a recent weakening from levels below 113.7 against the greenback. The Australian dollar was at $0.7135 after climbing from below 0.712 earlier this week.

Oil prices were mixed in the afternoon of Asia trading hours. International benchmark Brent crude futures traded slightly lower at $73.96 per barrel. U.S. crude futures climbed 0.14% to $71.22 per barrel.
