Shin-Etsu Chemical new domestic rare earth refinery

New rare earth refining plant that Shin-Etsu Chemical is building in Japan with a JOGMEC Critical Minerals Grant of about 17.5 billion yen (JFY2026 grant decision). The JOGMEC grant table states only that new refining equipment will be built 'in Japan' (日本国内); press reports place the plant in Fukui Prefecture, but no official or company source names the site, so the locality is recorded as not stated.
