Nikkei Surges Over 3% on Semiconductor Rally; KOSPI Falls

Japan's Nikkei 225 rose more than 3% to above 68,900, led by gains in chip stocks including SoftBank, Tokyo Electron, and Advantest following strong Micron earnings and AI demand. South Korea's KOSPI declined around 0.7% to below 6,800 on foreign selling spurred by surging US Treasury yields, despite semiconductor export strength.
