Japan stocks rise on AI and chip demand

The latest lift came even as broader conditions were mixed. U.S. stocks softened overnight on renewed concern about the Iran conflict and higher oil prices, while Japan faced a stronger yen near a seven-month high on expectations the Bank of Japan could raise rates again as soon as next week. In other words, this was not a risk-on day for everything — it was a stock-picker’s market, and semiconductors won.

That’s the key takeaway for long-term investors: the AI trade is broadening beyond the U.S. megacaps. Japan’s market is getting a second wind from companies linked to chip manufacturing, testing and high-precision industrial hardware. Furukawa Electric jumped 13.2%, Fujikura gained 8.75% and Lasertec rose 6.56%, while Kyowa Kirin, Sumitomo Pharma and Nikon lagged. The market’s message is clear: capital is flowing toward businesses with direct exposure to the next leg of digital infrastructure spending.

There is also a fundamental reason this rally has more staying power than a simple momentum burst. A Reuters poll showed confidence among Japan’s major manufacturers at the highest since December 2021, helped by resilient demand in semiconductors and data centers. That is exactly the kind of backdrop that can keep earnings revisions moving in the right direction, even if the yen remains firm and interest rates inch higher.

For investors, the immediate question is whether these gains can survive a tougher currency and higher borrowing costs. The answer depends on earnings quality. Companies with strong pricing power, export reach and clear AI exposure should be better positioned than domestically focused cyclicals. Japan’s semiconductor and electrical-equipment names also benefit from a deeper structural story: supply-chain diversification, government support for chip investment and rising demand for the hardware behind AI.

The long-term opportunity is real, but so is volatility. The Nikkei’s breadth was still weak, with more decliners than advancers, which tells you the rally remains narrow and concentrated in a handful of winners. That is not unusual in an early-stage secular theme. Over time, though, the companies that control critical parts of the AI supply chain can compound for years if demand keeps expanding.

For patient investors, the message is simple: Japan’s chip and AI ecosystem is worth watching closely, and selective exposure could make sense on pullbacks.
