Tokyo stocks rebounded from Thursday’s split finish as Wall Street’s technology surge returned buyers to index heavyweights. At the same time, firmer Tokyo inflation and a rising JGB yield brought the Bank of Japan’s next move back into the price of everything.

Market mood in one line: U.S. AI optimism lifted Tokyo, but TOPIX outperformed the Nikkei—evidence that the advance was broader than a handful of chip names.
The Nikkei rose as much as 513 points after the open on Thursday. Nvidia’s results and sales outlook reinforced the case that AI infrastructure spending still had room to run. The rally then lost its footing. Profit-taking in high-priced semiconductor names, including Advantest, pulled the price-weighted benchmark to a final loss of 130.18 points at 66,131.98.
TOPIX told a different story. It added 6.20 points to 4,117.22 for a sixth consecutive advance. A falling Nikkei and rising TOPIX meant Thursday was not a broad retreat. Money still found banks, materials and domestic businesses even as several index-heavy technology stocks weakened.
Nvidia climbed 8.7% in New York, while the S&P 500 gained 0.72% and the Nasdaq Composite 1.57%. Tokyo opened fractionally lower on Friday, then buyers returned to Advantest, Tokyo Electron and SoftBank Group. The Nikkei reached a morning close of 66,682.88, up 550.90, and remained clearly higher around 1:30 PM.
This was not a synchronized Asia-wide risk rally. Taiwan gained on the chip read-through, but South Korea’s KOSPI was down about 1% and Hong Kong was slightly lower in the morning. Tokyo’s strength was more specific: Japanese exposure to the AI supply chain, combined with a rising-rate benefit for financial stocks.
At 11:00 AM, Advantest was the largest positive contributor to the Nikkei, adding roughly 205 points to the benchmark by itself. The shares had fallen more than 3% on Thursday. Nvidia’s overnight surge and strong AI demand outlook brought buyers back on Friday.
The move mattered beyond one ticker. More powerful AI chips require increasingly complex testing, giving the market a direct line from a U.S. chip designer’s forecast to Japanese test equipment, production tools and electronic components. Tokyo Electron and Taiyo Yuden also rose, reinforcing the supply-chain interpretation.
There is an important limit to the signal. The Nikkei gives large influence to high-priced shares. Advantest’s huge index contribution does not mean Japanese households, smaller companies or the full domestic economy improved at the same speed.
Semiconductors and electrical equipment, IT services, banks and brokers. Advantest, Tokyo Electron and Taiyo Yuden gained during the morning. MUFG, SMFG and Mizuho also rose as higher yields improved the earnings narrative for lenders.
Utilities, construction and rubber products were among the softer groups. Higher funding and input costs weighed on rate-sensitive areas, while Fast Retailing and several other high-priced stocks restrained the Nikkei.
The Prime Market had 832 advancers, 655 decliners and 66 unchanged at the morning close. That was positive breadth, though not a one-way market. TOPIX outperforming the Nikkei showed that financials and other large domestic names joined the move.
The dollar traded around ¥159.3–¥159.4 through the morning and midday, close to its ¥159.35 level near Thursday’s Tokyo equity close. That was supportive for exporters’ translated earnings, but the same weak yen increases the cost of imported fuel, food and materials for households and smaller businesses.
The currency was not Friday’s main equity driver, yet it remains the hinge between Japanese and U.S. policy expectations. Tokyo inflation was firmer and BOJ rate speculation intensified. Later Friday, Federal Reserve Chair Kevin Warsh’s Jackson Hole remarks could move U.S. yields and USD/JPY after Tokyo closes.
Japan’s 10-year government-bond yield stood at 2.928% at 11:00 AM, 3.3 basis points above Thursday’s close of 2.895%. The bond selloff followed weaker U.S. Treasurys, while firmer Tokyo inflation and Deputy Governor Ryozo Himino’s remarks kept a possible September BOJ increase in view.
Higher yields support the income outlook for banks and insurers. They also raise discount rates and financing pressure for REITs, property companies, utilities and highly leveraged businesses. Friday’s TOPIX leadership was therefore consistent with two separate trades working together: AI capital spending and a more profitable rate environment for financials.
Wall Street’s Thursday session delivered a powerful technology signal, but it was less broad than the headline indices suggested. Nvidia jumped 8.7%, and Salesforce surged after results, while public reporting indicated that most S&P 500 constituents still declined. The U.S. 10-year Treasury yield held around 4.67% in Asian hours and the 30-year remained above 5.19%.
Europe’s cash markets had not opened by 1:30 PM Tokyo time. EURO STOXX 50 futures were about 0.3% higher, while S&P 500 and Nasdaq futures were roughly 0.1% lower. Brent crude traded near $89.63 a barrel and was headed for a weekly decline of more than 5% as diplomacy around Strait of Hormuz traffic reduced some immediate supply fear. Currency and bond markets were waiting for Warsh.
Tokyo’s core consumer-price index, excluding fresh food, rose 1.8% from a year earlier in August, up from 1.7% in July. The measure excluding fresh food and energy accelerated to 2.0%. As a leading indicator for nationwide inflation, the release made it harder for markets to dismiss price pressure as temporary or narrowly energy-driven.
On Thursday, Himino argued that monetary policy works with long lags and that adjusting accommodation at the appropriate time can reduce the danger of having to brake sharply after inflation accelerates. He did not promise a September increase. The combination of his message, Friday’s CPI data and higher JGB yields nevertheless forced markets to consider what comes after the current 1% policy rate.
Industrial policy supplied another long-term signal. Kioxia and Sandisk announced plans to invest about ¥5 trillion in Japan through 2032. Execution depends on government support. The scale illustrates AI’s demand pull, but it also keeps a difficult policy question in view: how much semiconductor expansion should be financed by companies, and how much by taxpayers?
What interested me today was that AI optimism and higher interest rates could lift different parts of the same market at once. Semiconductor companies have a demand story; banks have a rate story. For households and smaller companies paying for a weak yen and higher prices, neither is an uncomplicated victory. On a strong index day, it is worth asking who is producing the gain—and who is paying for it.
