The dollar inched up against the yen on Wednesday after upbeat U.S. economic data reinforced expectations for economic growth under Donald Trump's Administration and more rate hikes by U.S. Federal Reserve next year.

The dollar rose 0.2 percent against the yen to 117.67, adding to its gains of nearly 0.5 percent on Tuesday in the wake of data showing U.S. consumer confidence hit a 15-year peak in December.
