The Nikkei 225 staged a strong comeback following a market holiday, closing today, September 24, 2026, up 0.76% (approximately 0.8%) at 65,513.99 points. Buoyed by a rebound in overseas tech sentiment and a surge in artificial intelligence (AI) and chip-related high-tech stocks, the market was highly active throughout the session, at one point climbing over 1,200 points to reclaim the 66,000-point level.

Stimulated by the positive news of Meta Platforms, Inc. unveiling a new AI hardware device that boosted CPU-related demand, heavyweight tech stocks saw intense buying activity. Memory chip giant Kioxia jumped 3.9% during trading, SoftBank Group surged 6.8%, and Ibiden soared a massive 14%.

Despite overnight declines across major US indices, the 10-year US Treasury yield surged again to break above 5.1%, igniting dollar buying and pushing the yen to a low of nearly 158.4 against the dollar. The significant weakening of the yen directly benefited Japan's export-oriented companies, offsetting the negative pressure that falling US stocks exerted on the Tokyo market.
