Japan explained to its Group of Seven counterparts the yen's recent "somewhat rapid" declines, Finance Minister Shunichi Suzuki said Wednesday, underscoring Tokyo's growing alarm over the currency's sharp fall to a two-decade low against the dollar.

Suzuki did not comment on how the G7 finance leaders responded, saying only that the meeting in Washington focused on discussions over the global economy and Russia's invasion of Ukraine rather than exchange-rate moves.

In a statement issued after their meeting, the leaders said they were closely monitoring global financial markets, which have been "volatile," but made no direct mention of exchange rates.
