The yen has slumped to a level that leaves it on track for its worst year on record, prompting the strongest warnings to date from senior government officials aimed at stemming the slide.
The currency fell over 1% to ¥144.38 per dollar Wednesday in a third day of declines as a fresh wave of dollar strength ripped through Asia putting pressure on a range of foreign exchange levels.
Finance Minister Shunichi Suzuki noted the recent moves were very sudden and said the government will take action if needed, speaking to reporters.
