The U.S. dollar firmed to trade mostly around the 142 yen line in Tokyo, rebounding from a four-month low of 140.96 yen logged Thursday, which spurred investors to buy back battered shares following the yen's swift appreciation the previous day, analysts said.
Among major exporters, Sony Group added 405 yen, or 3.1 percent, to 13,365 yen, and Nissan Motor gained 15.7 yen, or 2.9 percent, to 550.5 yen.
