Japan Stocks Tumble, Yen and Bond Yields Rise as Tariffs Start

Japanese stocks tumbled while the yen and yields on government bonds climbed as concerns about US trade tariffs and wild swings on Wall Street dented investor confidence.

The broader Topix closed 3.4% lower at 2,349.33 in Tokyo, and the blue-chip Nikkei 225 Stock Average declined 3.9% to 31,714.03. Both were down more than 4% at one point on Wednesday, almost erasing Tuesday’s rally. The yen strengthened over 1% against the dollar before paring its advance to 0.9%.
