Nikkei 65,000, SEAJ +14%, Kioxia profit 48x: the backstage protagonists
The theme across 29 Japan semiconductor articles from May 23–26 is "quiet explosion." While Korea and Taiwan grab headlines, Japan's equipment and materials companies are quietly stacking record earnings and capital investments.
Nikkei 65,000 — The 'Buy Japan' Thesis
Nikkei hit a record 65,158, surging 1,819 points in three days. Kioxia traded at ¥2.4T market cap as AI/semis led the rally. The 'Buy Japan' trade is intensifying.
The curious case: Tokyo Electron (TEL) — profit declined, yet stock rose. An ex-buy-side analyst decoded it: the market is betting on TEL's long-term WFE market expansion, not short-term earnings. Nomura raised TEL's target price, and a mid-tier broker set PT at ¥63,000.
SEAJ: April Equipment Sales +14.1% YoY
SEAJ reported April chip equipment sales at ¥510.1B, up 14.1% YoY. This matters because equipment sales are the most direct leading indicator of the CapEx cycle. Customers (TSMC, Samsung, Intel) are building fabs, and much of that equipment comes from Japan.
TEL broke ground on a ¥10B logistics facility in Kumamoto — right next to TSMC's fab. Mitsui Fudosan handles design-build, and efforts to attract Taiwan suppliers to Kumamoto Science Park are underway.
Kioxia: Profit 48x YoY
Kioxia's Q1 net profit is projected at ¥869B, a 48x year-over-year increase on exploding AI data center NAND demand. S&P upgraded Kioxia's credit rating, and shares hit all-time highs.
Lasertec was cited as a 'tenbagger' candidate, with foreign buyers accumulating Japan's 'Global Niche Top' stocks (Lasertec, TOK).
Japan's Strategic Position
Analysis showed why Japan is relatively shielded from US-China chip tensions — key suppliers to NVIDIA and TSMC are concentrated in Japan, and neither the US nor China can substitute Japanese equipment and materials. This is the fundamental logic behind 'Buy Japan.'
Conclusion
Japan semiconductors are the "backstage protagonist." While Korea's HBM and Taiwan's foundry take the spotlight, Japanese equipment and materials companies are the most stable beneficiaries of the CapEx cycle. SEAJ equipment +14%, TEL Kumamoto expansion, Kioxia profit 48x — the numbers speak. What PMs should watch: Japanese equipment stocks tend to lead their customers' (TSMC, Samsung) CapEx announcements. TEL and Advantest order trends will preview next quarter's global CapEx direction.
