The Nikkei 225 Index fell 2.07%, approaching the 65,000 mark to trade at 65,028.06 points. The two major heavyweights also posted sharp losses: Kioxia fell 2.3% to trade at 46,800 JPY, while SoftBank dropped 5.12%, breaching the 5,000 mark to trade at 4,897 JPY.

Japanese and South Korean stock markets were influenced at the open today by a combination of multiple macroeconomic factors and spillover effects from external markets. Among them, U.S. tech stocks—especially the semiconductor sector—experienced a significant correction last Friday, directly dampening buying interest in tech stocks during Asian trading hours. In addition, Fed Chair Warsh delivered hawkish signals, worsening market concerns over the Federal Reserve's future monetary policy path. Worries that the Fed might maintain high interest rates or even raise them led to a general decline in market risk appetite, sparking capital outflows from risk assets.
