Japan's Nikkei slumps as tariff concerns, yen strength unsettle market

Japan's Nikkei dropped 1.8% on Tuesday amid concerns over U.S. tariffs on Canada and Mexico and a stronger yen. Exporter shares like Toyota were hit, and tech shares underperformed. The yen's strength followed President Trump's comments on currency values. The volatility index briefly spiked to a level last seen post the U.S. presidential election.
