The Two-Year Forward Curve — Why SEAJ Already Nailed FY2028 at ¥7.8T, and Why a -1,000pt Nikkei Session Didn't See It

When the tape looked at one day, the industry was already drawing a two-year curve

On July 2, 2026, the Nikkei 225 fell more than 1,000 points in a single session. US semiconductor weakness rolled straight into Tokyo, and simultaneous weakness in Taiwan and Korea pressed on Japan's equipment and materials supply chain. Read only the headline, and the narrative writes itself: the AI semi rally is cracking. But two quieter and much larger numbers landed the same week. First, SEAJ (the Semiconductor Equipment Association of Japan) raised its FY2026 domestic equipment sales forecast to ¥6.5 trillion (+26% YoY). Second — and this is the part almost nobody quoted — the same association already has FY2028 pegged at ¥7.8 trillion. The gap between those two numbers — two years, +20% on top of an already-raised base — is what this report is about.

¥6.5T for FY2026 is the start of the curve, not its endpoint

What SEAJ raised this week was not a single-year datapoint. The association took FY2026 up by roughly ¥1 trillion in one move, close to a 20% upward revision. But turn the page. For FY2028 the association is carrying ¥7.8T, which stacks another ~20% on top of the already-raised ¥6.5T FY2026 base. In other words, the point most street decks call "the 2026 AI capex peak" is not a peak inside SEAJ's own view — it is a waypoint. The trade group is effectively saying: Japan equipment sales have already doubled over five years, and the base case is that they climb another 20% inside the next two. That is why this is a structural story, not a cyclical one.

Infineon's ¥900B validates the curve at the plant-floor level

The same week, Germany's Infineon confirmed a ¥900 billion (~$6B) new power-semi fab in Japan. Line that up next to SEAJ's ¥1T upward revision and the picture sharpens. In the exact quarter SEAJ raises Japan's FY2026 equipment take by ~¥1T, a single foreign IDM signs off on a ¥900B fab commitment in-country. One fab absorbs almost the entire revision. Domestic logic and memory capex was already lifted; a foreign IDM's greenfield build now stacks on top of that. That is why FY2028 at ¥7.8T reads less like an optimistic assumption and more like an operator consensus already inked.

A -1,000pt Nikkei day is not a refutation of the curve

The same session's move — Nikkei off more than 1,000 points on US semi weakness, Korean semi spillover, and rotation into banks and autos — targeted momentum psychology in AI names. It did not target the SEAJ curve. What makes the tape more interesting is the contrast: foreign investors have net-sold ~₩149T out of Korean semis and rotated that capital into Japanese semis over H1, and a one-day correction did not reverse that flow. Short-term momentum selling (-1,000pt) and structural capital reallocation (₩149T rotation) are running in opposite directions through the same window.

Side data: memory spot still points up

DDR5 16Gb spot printed $46.667 on 2026-07-05. If Tuesday's correction had genuinely shifted the tone across memory and AI capex, spot would have moved first. It didn't. That tells us the pullback is a price re-set, not a story break, and it does not carry into the variables that would actually threaten the SEAJ curve.

Where the curve actually lands — Tokyo Electron (8035)

When the FY2028 ¥7.8T scenario clears, the largest single absorber is the front-end equipment stack that carries the highest capex-per-fab share. That maps directly onto Tokyo Electron's (8035) coater/etcher/cleaner/deposition portfolio. Advantest (6857) disclosing buyback progress the same week is a different point on the same curve — Advantest sits on the sharp tip of the HBM/AI test capex line, while TEL sits under the whole area of the front-end curve. Around them: Shin-Etsu Chemical (4063) in silicon wafers and photoresist raws, Tokyo Ohka Kogyo (4186) in photoresist, Disco (6146) in dicing and grinding. Even outside the core universe, Nippon Kayaku is repositioning from automotive-safety leadership into semiconductor materials, and a separate industry read the same week described Japanese material makers regaining competitive ground in mid-process (中工程) manufacturing. Every time the curve steps up, there is more than one node absorbing it.

Positioning: what's priced, what isn't

Already in prices: the FY2026 raise, the ₩149T rotation, HBM test capex acceleration, Advantest's buyback signal. Not yet priced: the slope implied by FY2028 at ¥7.8T — another +20% on top of an already-raised base — and the fact that Infineon's ¥900B translates that slope into a plant-floor commitment. A -1,000pt Nikkei day does not negate that curve; it reopens the entry into it. Tokyo Electron (8035) remains the natural absorber of that curve, and the case for it does not depend on the correction ending this week.
