TOKYO - Japan remains ready to take "decisive" action against the yen's depreciation, Finance Minister Satsuki Katayama said Tuesday, as the currency hovered in the lower 160 zone against the U.S. dollar, near a level that previously triggered an intervention by Japanese authorities.

"Given the circumstances, there is no change in the fact that we are increasingly in a position to take decisive action," Katayama said when asked about the yen trading in the lower 160 zone Tuesday morning.
