Japan used 3.34 trillion yen in February to intervene in the currency market to keep the yen from rising against the dollar, the Finance Ministry said Friday.
This brought the total amount of funds used for such operations from the beginning of the year to 10.49 trillion yen.
Japan used a record 7.15 trillion yen in January to stem the yen's rise. A stronger yen hurts the nation's exports, the main driver of the nation's economy.
