Japan's Nikkei share average fell in a broad sell-off on Wednesday, tracking Wall Street's overnight declines amid worries about slowing growth as hopes for U.S. tariff concessions faded.

Japan’s share benchmark nosedived on Monday after the meltdown Friday on Wall Street over U.S. President Donald Trump's tariff hikes.

The week got off to a shaky start in Asian markets, where major indexes in Japan, South Korea and Taiwan all dropped at least 3%. Those regions are particularly dependent on exports to the U.S. and haven’t been hit with broad tariffs yet.
