日本語Re-Cut|大引けで分化はさらに拡大——日経−1.79%、TOPIX+1.16%

The Nikkei fell 1.79% while the TOPIX rose 1.16%. Japan did not simply sell off—it split in two.

Tokyo Closing Dispatch — 5 November 2026, 15:30 JST

Tokyo closed with one of those tapes that punishes anyone who relies on a single headline index.

The Nikkei 225 finished at 61,077.85, down 1,110.78 points, or 1.79%. The TOPIX closed at 3,940.39, up 45.01 points, or 1.16%.

Same country. Same session. Opposite verdicts.

The morning diagnosis—this was a violent repricing of the AI and semiconductor complex, not a blanket rejection of Japan—survived the full session. In fact, the divergence became more extreme. The expensive, high-price technology names that exert heavy influence on the Nikkei kept absorbing damage, while autos, financials, trading houses, pharmaceuticals, retail and other parts of the broader market carried the TOPIX higher.

The cleanest image for the close is not a market crash. It is an export inspection.

Donald Trump arrives at the Tondemo Nippon departure gate with an overloaded trolley: chips, wafers, data-centre racks, miniature plants, factory-automation arms, telecom equipment, precision machinery, steel coils and a suspiciously large bottle labelled ULTRAPURE WATER. The JPX inspector takes one look and points to the secondary-inspection room.

Nothing to declare? Not today.

One market, two index systems

The Nikkei 225 is price-weighted. The TOPIX is a broad, free-float-adjusted market-capitalisation index. That construction difference mattered enormously today.

When high-priced semiconductor equipment shares fall together, the Nikkei can look like Japan itself is being liquidated. The TOPIX told a different story: capital was not simply leaving the country; much of it was moving across the market.

That distinction is more than index trivia. It changes the trading decision.

If the Nikkei is weak but the TOPIX is firm, “Japan risk-off” is too crude a conclusion. The correct question is: which supply chains are being sold, and where is the money being redeployed?

The AI supply chain was detained at the gate

The late-session heat map showed the damage clearly. At the 14:42 JST snapshot:
