Toilet Maker, MSG Giant Profit From Japan's AI Boom

4 min read

Toto, the company better known outside Japan for its high-end toilets, has become an unlikely name in the country's chip-driven boom. So has Ajinomoto, the seasoning maker behind the MSG in kitchens worldwide. Both show up in supply chains tied to the semiconductor and data center buildout now reshaping Japan's economy, a shift that's pulling in firms with no obvious connection to artificial intelligence.

That story sits in this edition of The Download, MIT Technology Review's weekday newsletter, alongside NASA's Nancy Grace Roman Space Telescope, set to launch as early as next month with the first space-bound "active" coronagraph, a device built to blot out starlight so astronomers can photograph planets that resemble the ones in our own solar system. There's also a look at PsiQuantum's attempt to build a massive quantum computer out of light, housed in cabinets that its own engineers describe as part data center, part ice cream factory.

The technology will allow astronomers to take the first pictures of planets orbiting other stars that are similar to those in our solar system. Ultimately, it could pave the way for a future mission that could snap the first photos of Earth-like worlds.

Why this matters For anyone building on top of AI compute, this is a reminder that the boom's real chokepoints sit far from the model layer. Ajinomoto's insulation film and Toto's ceramic components aren't glamorous, but they're load-bearing parts of the chipmaking process that determines how fast Nvidia and TSMC can actually ship. When an MSG company becomes a critical node in semiconductor supply, it tells us the AI hardware stack is thinner and stranger than the clean narratives about GPUs and data centers suggest.

Founders betting on compute availability should be tracking materials suppliers with the same attention they give chip fabs, because a bottleneck at Ajinomoto's film production or Toto's ceramics line moves timelines just as much as a TSMC delay would. It's also a useful check on the assumption that AI's winners will only be the obvious names in Silicon Valley or Taiwan. Japan's industrial base, built for decades on unrelated consumer products, turns out to have exactly the precision manufacturing this buildout needs.

Worth watching whether more "boring" suppliers get pulled into the AI story next.

Common Questions Answered

How are Toto and Ajinomoto connected to Japan's AI boom?

Toto and Ajinomoto have become unlikely participants in Japan's chip-driven AI boom through their roles in semiconductor and data center supply chains. Despite having no obvious connection to artificial intelligence, both companies supply critical components—Toto provides ceramic components and Ajinomoto provides insulation film—that are essential to the chipmaking process.

What are the load-bearing parts of the chipmaking process mentioned in the article?

According to the article, components like Ajinomoto's insulation film and Toto's ceramic components are load-bearing parts of the chipmaking process that determine how fast companies like Nvidia and TSMC can ship their products. These unglamorous materials are critical to semiconductor production despite not being part of the visible AI model layer.

Why does the article describe the AI hardware stack as 'thinner and stranger than clean narratives'?

The article suggests that when an MSG company becomes a critical node in the semiconductor supply chain, it reveals that the AI hardware stack is more complex and unconventional than typical narratives about GPUs suggest. The real chokepoints of the AI boom sit far from the model layer, involving unexpected players in unglamorous but essential supply chain roles.

What shift is reshaping Japan's economy according to this article?

The semiconductor and data center buildout tied to artificial intelligence is reshaping Japan's economy, pulling in firms with no obvious connection to AI into critical supply chain roles. This shift demonstrates how the AI boom extends beyond traditional tech companies to encompass a wide range of industrial suppliers.
