Certification April 2026. Security grade March 2027. Building done Feb 2028. Revenue after that. Subsidy paid against a plan; requirements added to the plan afterwards. Deep dive & structural friction analysis in the Bio.
Meanwhile the segment carrying all of this — High-Performance Materials, 61.6% of group operating profit — is guided to grow 0.6% next year. And a quarter of its FY26 profit gain came from switching depreciation to straight-line, not from operations.
Zeon broke ground at Tokuyama on 25 Aug for a plant making dozens of times its current single-wall nanotube output. Certified by METI in April 2026. The security grade attached to that certification starts March 2027. The plant runs 2028. #JapanEquities #SupplyChain
Full structural analysis: four scenarios, probability matrix anchored on base rates, watchlist thresholds and structural response rules, for supply chain and procurement readers. → Japan Upstream Alpha, this Premium issue. {{japanupstreamalpha.substack.com/p/sumitomo-che…}} #JapanEquities
Most likely outcome (45%): the export controls hold and the volume diameter stays at 4 inches. The uncomfortable one sits at 20%. Controls hold, demand migrates to 6 inches, and the premium becomes real and uncollectable. Full breakdown in this issue.
Sumitomo Chemical started selling 4-inch InP epiwafers on 31 Aug. Shares +11.5% over two sessions, filed by the market as AI data centre exposure. The list item that actually moved them is 3C004.a. A structural breakdown. #JapanEquities #Semiconductor
Full structural analysis: the four scenarios and the early warning indicators behind them. Japan Upstream Alpha, this Premium issue. {{japanupstreamalpha.substack.com/p/asahi-kasei-…}} #JapanEquities #SpecialtyChemicals
Most likely outcome (33%): the format wins its generation. The one that is not the headline story sits at 22% - the film clears, and the window it cleared into is closing.
Asahi Kasei guides Material revenue down 0.4% and operating profit up 18.6%. The company names the product behind the mix: PIMEL. The film meant to extend it is still under customer evaluation. A structural breakdown. #JapanEquities
