Japan's stock market, specifically the Nikkei 225, has reached an unprecedented all-time high, surpassing 68,000 for the first time, driven by a global fervor for artificial intelligence. This surge marks a significant year for the Japanese market, which has already seen a nearly 33 percent increase in 2026. Companies involved in the semiconductor industry, such as Tokyo Electron, Advantest, and Shin-Etsu Chemical, have been leading the gains. The weak yen is also contributing to this positive trend. This AI-fueled rally is not isolated to Japan, as it has propelled stock markets in the US, South Korea, and Taiwan to record highs, with major chipmakers like SK Hynix, Samsung Electronics, and Micron achieving market capitalizations of at least $1 trillion.
