Kuroda's remarks were made to reporters in Davos on Thursday, when asked about U.S. Treasury Secretary Steven Mnuchin's comments that a weak dollar was good for the U.S. economy, Kyodo reported.

Kuroda also shrugged off lingering market speculation that the BOJ would dial back its huge stimulus programme earlier than expected.

"There is still quite some distance to our 2 percent inflation target. It's inappropriate to talk about an exit strategy or a change in policy," Kuroda said.
