Japan's Nikkei share average closed higher for a third consecutive session on Wednesday, supported by AI-related shares, though fresh hurdles in U.S.-Iran peace negotiations and investor caution in a volatile market limited gains.
The benchmark Nikkei 225 advanced 0.59% to close at 70,474.96, paring an earlier surge of as much as 2.7%. The broader Topix ended 0.42% higher at 4,011.50.
