Japanese manufacturers of toilets, glass fibre and seasoning have become surprise AI-boom winners by supplying critical materials to semiconductor manufacturing: Toto makes ceramic chucks for chip equipment, Nittobo supplies glass fibre for package substrates, and Ajinomoto produces insulating films for high-performance processors.
This Wire brief sits within Fusion42's coverage of Semiconductors and AI Infrastructure.
◆ ◆ The Wire takeaway
If you're building chip manufacturing equipment or advanced semiconductors, your supply chain now runs through companies that spent decades solving problems in toilets and seasoning. These three just proved that unglamorous materials science companies can grow faster than the chip makers they serve—which means your supplier has fewer reasons to sell to you instead of growing its own margin.
