Nikkei 225 · July 28, 2026
Seoul's chip rout reaches Tokyo
-3.95%
single-day change vs previous close
Part of a longer stretch
The same argument, shallower in Tokyo
near the end of it · 2026-06-25 → 2026-07-29, -15.11% over the whole period
What happened that day?
- 28 July 2026 — the Nikkei 225 fell 3.95% to close at 62,364.92
- Korean stocks collapsed by a double-digit percentage the same day. Tokyo took it in real time — the two markets trade almost the same hours
- Chip equipment and test-equipment makers and memory firms fell hardest. Japan's damage sat with the companies selling the machines, not the chips
- US chip stocks had already slid the previous session. This started in America, not in Asia
- One worry ran through it: the AI capital spending the large technology companies were pouring out had not yet come back as revenue
- If it does not come back, spending gets cut — and cut spending means less demand for high-bandwidth memory. That arithmetic pushed Korea and Japan down together
- From the late-June high to the 29 July low the index fell 15.11%. Korea's decline over the same stretch was far deeper
