The Nikkei 225 Index opened near the 67,000 mark before retreating from earlier highs, gaining just 0.44% to trade temporarily at 66,550.43 points. Heavyweight stocks rose across the board, with Kioxia gaining 6.08% to break above the 50,000 mark and trade temporarily at 53,040 JPY, while SoftBank rose 1.51% to trade temporarily at 5,241 JPY.

Japanese and South Korean stocks opened broadly higher, driven primarily by the overnight better-than-expected performance of U.S. semiconductor giants, falling U.S. Treasury yields and oil prices easing inflation pressures, as well as a tracking rebound in tech heavyweights. Notably, after the U.S. market close, Nvidia (NVDA) released better-than-expected Q2 earnings, with revenue surging over 100% year-over-year. Robust AI chip demand once again shattered market concerns over an AI investment bubble, directly driving a rebound in Asian chip stocks and injecting a shot in the arm for Japanese and South Korean stock markets reliant on the semiconductor supply chain.
