Shin-Etsu Chemical (TYO:4063) plans to build a new rare-earth refinery in Fukui Prefecture, its third such facility, to secure a stable supply of magnets and related products, Bloomberg News reported on Friday.
The project will involve over $218 million in investment, with roughly half of the funding coming from government subsidies, the newswire said, citing an earlier report by Nikkei Asia.
The move comes as China has halted exports of certain key materials since early 2026 amid tensions over Japanese Prime Minister Takaichi's comments on Taiwan, the publication said.
Shin-Etsu Chemical did not immediately respond to' request for comment.
