Japan & China technology, translated and contextualized for Western readers
Every company that supplies, builds, or deploys AI in Japan, China, South Korea, and Taiwan, scored on what it discloses and ranked against the rest.
Coverage of Asian AI is usually organised by country, which is the least useful cut. The supply chain does not stop at borders: a Chinese accelerator is fabricated in Taiwan, on equipment built in Japan, around memory made in Korea. The directory is therefore sorted by layer first.

Ranked on disclosed scale, which rewards incumbency: the head of this list is memory, foundry, and packaging, not model labs. How the score is built.

Company counts are a measure of coverage, not of capability. What the rankings show is specialisation: each of these markets holds a different segment of the same supply chain.
56 companies · best rank #5
China has the most companies here and the widest spread across layers, because it is the only market building a full domestic stack. Breadth is not the same as depth: several of its most consequential firms are unlisted, and so unrankable.
Concentrated in Edge AI & Devices and Enterprise Applications.
42 companies · best rank #4
Japan is strongest where the stack is least visible: lithography optics, photoresists, wafer handling, testing, precision components. Few of these firms sell anything an AI user touches, and most of the world’s accelerators cannot be made without them.
Concentrated in Equipment & Materials and Silicon & Foundry.
35 companies · best rank #3
Taiwan holds the manufacturing chokepoint — leading-edge foundry and advanced packaging — plus the server ODMs that assemble most of the world’s AI racks.
Concentrated in AI Server Hardware and Power & Infrastructure.
31 companies · best rank #1
Korea is concentrated to an unusual degree. Two firms supply most of the world’s high-bandwidth memory, and that single dependency carries the country’s position in the index.
Concentrated in Edge AI & Devices and Enterprise Applications.
The index scores disclosed financial scale. That is a real measure and a narrow one, and the distance between the two is where most of the interesting companies live.
23 of the 164 companies profiled here carry no rank — privately held, state-backed, or a subsidiary whose numbers are folded into a parent’s. They are not absent from the stack. They are absent from the filings.
Two further limits worth stating plainly. The score is weighted toward revenue, so it measures the size of a business rather than the importance of a technology — a materials supplier with one irreplaceable product will always rank below a diversified conglomerate. And it is a snapshot: rank movement between updates is usually currency and disclosure timing, not a change in the industry. Read the methodology.
