The Nikkei 225 Index was little changed above 63,400 on Wednesday as investors assessed stronger-than-expected Japanese trade data ahead of a key U.S. Federal Reserve decision. Exports rose more than anticipated in August, helped by demand for AI-related chips despite supply disruptions linked to the conflict in the Middle East. The U.S. central bank was widely expected to raise interest rates later Wednesday, while the Bank of Japan was also seen as likely to tighten policy on Friday. Investors continued to consider safety concerns around AI development after Nvidia CEO Jensen Huang rejected the need for additional AI security regulations, saying market forces would encourage companies to innovate safely. Technology shares were mixed, with Kioxia and SoftBank Group falling 2.7% and 3.7%, respectively, while Taiyu Yuden and Advantest gained 0.6% and 0.5%.
