6 November 2026, Tokyo close (15:30 JST; reporting checked 08:49 GMT). Japanese equities ended Friday’s session sharply lower as the global sell-off in artificial-intelligence and semiconductor shares spread from Wall Street into Asia. The Nikkei 225 finished at 57,434.77, down 5.96% from Thursday’s 61,077.90 close, according to dated market-close data carried by Yahoo Finance and the Wall Street Journal. This is a completed Tokyo session, not a live quotation.
Why the Nikkei was vulnerable
The pullback followed Thursday’s US equity rout, when the Nasdaq Composite lost 5.5% and the S&P 500 declined 4.4%. That US decline is already covered separately by NetNapz; Friday’s distinct development is the transmission of the shock to Japanese listed equities. Large Japanese technology and chip-equipment exposures, including SoftBank-linked AI investments and semiconductor names such as Kioxia and Advantest, were central to the retreat, according to contemporaneous financial reporting.
The market narrative combines several concerns, not a proven single cause: elevated AI-related valuations, financing costs for large data-centre projects, uncertainty over the eventual returns on capital expenditure, and the possibility of tighter US political scrutiny following midterm elections. These are investors’ interpretations and potential policy risks; no specific US restriction should be treated as enacted merely because markets priced in that possibility.
Market implications beyond Japan
Japan’s sell-off coincided with severe semiconductor-led declines in South Korea, highlighting the concentration of the AI hardware supply chain across Asian equity benchmarks. In a risk-off episode, Japanese government bonds can attract demand even while equities decline, but movements in yields and the yen require separate timestamped quotations before any directional claim is made. Traders should also distinguish Friday’s Tokyo close from the still-open European session and the upcoming US trading day.
For investors, the next tests are whether US technology shares stabilise, whether AI capital-spending plans actually change, and whether selling pressure broadens into Japanese companies without direct exposure to semiconductor spending. A dramatic index decline is evidence of repricing, not proof that corporate earnings or capital expenditure have already deteriorated.
