4th September 2026 – (Tokyo) Atsushi Mimura, who serves as Japan’s top currency official, has reiterated his commitment to closely monitor fluctuations in the exchange rate, amid persistent volatility in the yen. Speaking to reporters on Friday, Mr Mimura confirmed that Japanese authorities remain in constant communication with their United States counterparts as they observe recent developments in the foreign exchange markets.
Following Mr Mimura’s remarks, the dollar weakened to 155.305 yen, underscoring ongoing uncertainty and market sensitivity to possible official intervention. Just a day earlier, the yen had surged by two per cent against the United States dollar, spurring speculation among investors that Japanese authorities had moved to support the currency, despite an absence of confirmation of any formal action.
