The Nikkei 225 index fell 0.25% to close at 37,752 on Wednesday, reversing earlier gains after the Bank of Japan kept interest rates unchanged, citing uncertainty over the potential impact of U.S. tariffs on Japan's export-driven economy. While the central bank reiterated expectations for above-potential economic growth, it also acknowledged signs of weakness. The monthly Reuters Tankan survey showed sentiment among Japanese manufacturers turned negative in March due to concerns over U.S. trade policy and slowing economic activity in China. Meanwhile, Japan's trade balance swung to a surplus in February, supported by strong exports. Significant losses came from index heavyweights Fujikura (-5.3%), Disco Corp (-5.2%) and Advantest (-4.8%).
