The euro briefly nudged higher after Greece's parliament approved the government's new austerity measures, which were needed to secure the next tranche of bailout money from international lenders.
But the single currency quickly gave back those gains. The euro touched a low of 101.75 yen earlier, the euro's lowest level against the Japanese currency in about a month.
After trimming some of its losses, the euro stood at 101.94 yen, down 0.2 percent from late U.S. trade on Wednesday.
The dollar slipped 0.1 percent to 79.91 yen, staying below a six-month high of 80.68 yen set last week.
