The last time Suzuki used the words "decisive steps" was in autumn 2022 when Japan last intervened in the market to stem the yen weakness. Those words were used in prelude to currency intervention in the past.
Suzuki made the remarks shortly after the dollar spiked on strong U.S. data, nudging the Japanese yen to a 34-year low and into the zone that drew official market intervention in 2022.
The yen traded at 151.97 per dollar in the Asia session, down about 0.2% and weaker than 151.94 where Japanese authorities stepped in during October 2022 to buy the currency.
It hit the weakest level since the middle of 1990, around the time Japan's asset bubble burst.
Suzuki said the government is closely watching market moves with a high sense of urgency following the yen's fall.
