In morning Tokyo trade, the dollar weakened to 90.83 yen against 91.05 yen in New York on Wednesday, while the euro bought 123.23 yen from 123.54 yen.
The single currency was unchanged at $1.3564.
"Players are sidelined looking for fresh elements to trade," said Teppei Ino, currency analyst at the Bank of Tokyo-Mitsubishi UFJ.
"They have also refrained from taking long positions ahead of US payroll figures," scheduled for Friday, he added.
The dollar saw selling pressure after data showed the US economy contracted 0.1 percent in the last quarter of 2012, while a surge in eurozone confidence also had traders turning away from the greenback.
Eyes are on the release on Friday of non-farm payrolls figures, looking for fresh clues to the state of the economy.
The euro pushed sharply higher early on in European trade Wednesday, topping the $1.35 level for the first time in 13 months after the European Union's eurozone confidence index jumped for a third straight month as debt concerns slowly ebb.
