The Nikkei 225 Index slipped 0.6% to around 44,630 while the broader Topix Index lost 0.8% to 3,142 on Wednesday, retreating from record highs after weak trade data fueled concerns about Japan’s export-driven economy. Exports fell 0.1% in August, a smaller drop than expected but marking the fourth straight monthly decline, with shipments to the US plunging 13.8%. Imports also contracted 5.2%, easing from July’s 7.4% fall but still exceeding the 4.1% decline forecast by analysts. Japanese stocks also mirrored overnight losses on Wall Street as investors turned cautious ahead of the Federal Reserve’s policy decision. Among major movers, SoftBank Group slid 1.8%, Advantest 1%, Fujikura 1.9%, Mitsubishi UFJ 1.1% and Nintendo 1.7%.
