The Nikkei 225 Index rose 0.6% to above 66,000 on Wednesday, extending its previous-session gains as lower oil prices reduced near-term inflation concerns. Japanese shares also benefited from overnight gains on Wall Street and a sharp decline in long-term Treasury yields, although investors continued to seek clarity on the U.S. government’s fiscal reform plans. Traders were also awaiting Nvidia’s earnings report later in the global day for indications of demand related to artificial intelligence. Advantest gained 2%, SoftBank Group rose 2.7% and Mitsubishi UFJ advanced 1.6%. Terra Drone surged more than 20% after Japan’s Acquisition, Technology & Logistics Agency selected it to supply the Japan Self-Defense Forces with its Terra B1 interceptor drone under a fast-tracked program designed to strengthen counter-uncrewed aircraft capabilities.
