May 02 (News On Japan) –
Japan’s stock market is drawing fresh attention as the Nikkei 225 gains momentum and global investors look more seriously at Japanese technology shares.
What makes this shift stand out is not just the strength of the rally itself, but the growing sense that parts of Japan’s tech sector still look cheaper than their American peers. When international money starts searching for value, Tokyo quickly returns to the conversation. Reuters reported on April 23 that foreign investors poured another 2.38 trillion yen into Japanese stocks in the week through April 18, helped by improving risk sentiment and a rally in artificial intelligence related names.
That comparison has become sharper as the S&P 500 faces a tougher valuation conversation while Japan’s market benefits from a rotation into names seen as relatively undervalued. On April 23, Reuters reported that the S&P 500 fell 0.41% as oil prices climbed and geopolitical tensions added pressure to Wall Street, while Japanese equities were still attracting strong foreign inflows tied to optimism around AI and technology stocks. For many portfolio managers, this is no longer just a regional trade. It is a decision about where upside looks cleaner from here.
Why investors are turning back to Japanese tech
Japanese tech stocks are benefiting from a mix of momentum and relative value. That combination matters. In the United States, many large technology names already carry rich valuations, so investors have become more selective. In Japan, by contrast, the story feels earlier in the cycle. The companies are well known, the AI theme is real, and the pricing still looks less stretched. That is usually when global funds start leaning in. BlackRock said in its 2026 outlook that investor demand to diversify beyond the United States was one reason Japanese equities had already surged in 2025, and it suggested that trend could continue this year.
There is also a local angle here that matters. Traders in Tokyo have watched names like SoftBank, Advantest, and Tokyo Electron become central to the Nikkei move, especially as artificial intelligence enthusiasm keeps feeding demand for semiconductor and related technology exposure. Reuters reported that on April 23 the Nikkei briefly crossed 60,000 for the first time, with SoftBank up sharply and chip related shares helping lead the push higher. Think of it like capital following a familiar current, but finding a less crowded channel on the Japanese side.
Why the Nikkei 225 is holding an edge over Wall Street
The Nikkei’s recent strength is not happening in a vacuum. While Wall Street still has powerful growth stories, the mood has become less straightforward. Oil has turned into a bigger source of concern, Treasury yields remain elevated, and investors are starting to ask whether some US names have already priced in too much good news. Reuters noted that even with strong earnings beats from many S&P 500 companies, markets still moved lower on April 23 as geopolitical stress and higher oil prices clouded the outlook.
Japan, meanwhile, is offering a different mix. Foreign money has returned aggressively, and a big part of that is tied to technology and AI related optimism. Reuters reported earlier in April that foreigners had already poured 2.96 trillion yen into Japanese stocks in one week, reversing a large share of the prior outflows. That kind of buying tells you this is not just retail excitement. Larger investors are repositioning. Why does that matter? Because once big funds start treating Japan as a serious alternative rather than a side allocation, momentum can build faster than many expect.
What this means for Japan’s market outlook
For Japan, this rotation is more than a short term market story. It strengthens the case that Tokyo can compete again for global growth capital, especially in sectors tied to chips, AI infrastructure, and digital services. A trader in Osaka or Tokyo might notice the difference not only in index levels, but in how quickly certain tech names now respond to overseas sentiment. The market feels more connected, more watched, and more willing to attract global money than it did just a few years ago.
That does not mean the path will be smooth. Reuters also reported that much of the rebound has been narrow, with a record high NT ratio showing just how heavily the Nikkei has depended on a relatively small group of technology linked shares. Still, that concentration cuts both ways. If investors remain convinced that Japanese tech is still cheaper than the US equivalent, the rotation may have more room to run.
Conclusion
The Nikkei 225 is outperforming because it sits at the intersection of two powerful ideas: renewed foreign interest in Japan and a search for tech exposure that does not look as expensive as Wall Street. That is a compelling mix, especially while the S&P 500 faces tougher scrutiny on valuation and market sensitivity to oil and geopolitics.
For global investors, Japan is starting to look less like a secondary choice and more like a market with its own momentum. And for Japanese tech stocks, that may be the most important signal of all.
