Japanese stocks ended in the red on Thursday after U.S. President Donald Trump announced larger-than-expected tariffs, disrupting trade and supply chains.

The Nikkei 225 fell 2.78%, or 992.53 points, to close at 34,733.34.

The U.S. imposed 24% tariffs on Japanese imports as President Donald Trump unveiled a sweeping trade policy, setting a base rate of 10% and hitting key Asian partners with higher tariffs.

China faces 34%, Vietnam 46% and South Korea 25%, while the EU gets 20% duties.

Trump also closed a loophole that allowed low-value Chinese goods to pass through without being taxed, a blow to its e-commerce giant. Trading partners are expected to retaliate, raising the risk of price spikes and supply chain disruption.
