TOKYO: Japan's Nikkei share average jumped back above the key 50,000 mark on Thursday, led higher by technology stocks after strong results from Nvidia eased valuation concerns over the artificial-intelligence sector.

The Nikkei 225 Index jumped 3.5% to 50,254.38, set to snap a four-session loss, if the current momentum persists. The broader Topix was up 2.3%.
