U.S. dollar mark in Tokyo's foreign exchange market on Thursday, reaching its highest level since early December before slightly retreating during Friday's midday trading. The yen's recent rebound is largely attributed to growing expectations that the Bank of Japan (BOJ) may raise interest rates further.

The U.S. dollar briefly fell below 150 yen for the first time this year early Thursday, as the Japanese currency is bolstered by expectations of more interest rate rises by the Bank of Japan and the buck is seen suffering from uncertainty over President Trump's tariff policies.

The dollar fell slightly against a basket currencies, largely led by a stronger Japanese yen rather than a broad-based decline, according to ING.
