Toilet maker Toto, famous for its high-tech bidets and heated seats, has drawn investor attention. The company makes electrostatic chucks, which are critical components used in the production of NAND memory chips.
It's not just Toto. Japanese food giant Ajinomoto, better known for its umami seasonings and soup bases, has become an unlikely AI infrastructure play. The company produces an insulating material used in advanced semiconductor packaging.
Personally, would recommend Ajinomoto MSG.
They make some nice frozen foods too, which Costco carries. I like their frozen fried rice packets. They're quick to throw in the microwave for lunch.
