Japan Daily Briefing

DW reported Asian stocks slumped in lockstep with the US tech rout as AI regulation fears swept global markets. Nikkei futures hit -7% at the worst point before recovering to flat, a swing that illustrates how tightly Japan's electronic supply chain is coupled to US hyperscaler spending. Tokyo Electron, Lasertec, and Advantest — the core Japan semicap trio — face a double whammy: softer near-term demand signals and the prospect that Democrat-led AI regulation directly crimps the capex cycle their customers have been riding.

StockMarketWatch flagged surging capital flows into Japan as the Nikkei futures selloff intensified — a pattern consistent with global rotation out of AI-exposed US tech into lower-multiple Japanese value. TOPIX divergence vs Nikkei 225 is the read to watch: if Toyota, trading houses (Mitsui, Sumitomo), and megabanks hold relative strength while semicap names bleed, the rotation thesis stays intact. BoJ's silence on FX intervention above 152 suggests the central bank is comfortable watching USD/JPY as a natural shock absorber for now.

Toyo Keizai reported that Nippon Kodoshi Corporation — a specialist in electrical insulation separators — raised its full-year guidance on exploding AI server demand. The upgrade is a data point in the other direction from the market panic: while US equities are pricing in regulatory risk, Japan's materials and components supply chain for AI infrastructure is seeing genuine order acceleration. Nippon Kodoshi's upward revision suggests the capex cycle is too far advanced to stop cold — but whether that revenue lands in a world of tighter AI regulation remains the ¥trillion question for FY2027.
