From Toilets to AI Chips: Toto Joins MSG Maker Ajinomoto as Japan’s Strangest Beneficiaries of the AI Spending Frenzy

Toto said it will expand production of semiconductor parts, especially electrostatic chucks used in chipmaking for AI chips.

The announcement sent Toto shares up about 18% to a five-year high.

The move highlights how AI demand is boosting suppliers far beyond the tech sector.

The report also cites Ajinomoto as another non-tech winner from demand for chip packaging materials like ABF substrates.
