The Nikkei 225 Index rose 0.5% to above 64,200 on Thursday, while the broader Topix Index advanced 1% to 4,100, extending gains from the previous session. The yen weakened against the dollar after the Federal Reserve raised interest rates and signaled further tightening to contain inflation, improving the earnings outlook for Japan's export-focused industries. Declining oil prices also supported sentiment as markets anticipated a possible resumption of crude flows through Saudi Arabia's East-West pipeline, which would ease pressure on the oil-dependent economy. Gains were broad-based, led by SoftBank Group, Mitsubishi UFJ, Fujikura, Mitsubishi Heavy Industries and Nintendo. Earlier trading had also been supported by buying in artificial intelligence and semiconductor shares, although U.S. rate concerns and the Bank of Japan's policy decision had constrained risk appetite.
