Nikkei 225 Opens Higher on Chip Stock Gains

At the open, the Nikkei rose 0.89% to 65,600.42, or 579.48 points, after the Philadelphia semiconductor index surged more than 3% on Friday. That broad-based U.S. chip rebound also came as the dollar steadied after U.S. jobs data eased recent yen strength, reducing one headwind for exporters. In early Tokyo trade, Advantest was roughly flat, while Tokyo Electron, SoftBank Group and Toyota Motor all traded firmer. Banks such as Mitsubishi UFJ Financial Group lagged.

The market response shows how concentrated leadership remains. Investors are still rewarding companies exposed to AI infrastructure, even as other sectors struggle to keep pace. That is especially important for Japan, where the Nikkei’s gains increasingly depend on a relatively small group of globally linked technology names rather than on the domestic economy alone.

For investors, the message is not to chase every intraday swing, but to recognize the durability of the semiconductor upcycle. AI demand is still driving orders for chips, testing tools and manufacturing equipment, and that can support revenue growth well beyond the next quarter. Of course, these shares remain volatile, and a stronger yen or any pause in AI spending could cool sentiment quickly. But the bigger picture still favors companies tied to the infrastructure of computing power.

If you own a diversified portfolio and think in years, not days, this kind of move is worth watching rather than fearing. The winners in AI are not limited to the most obvious U.S. names; Japan’s chip ecosystem may keep benefiting as long as capital spending on semiconductors stays elevated.
