Robot density · AI infrastructure · AV fleet · Automation score
On measured robot density — the standard gauge of manufacturing automation — Japan leads with 446 robots per 10,000 manufacturing workers against China's 166 (2024 data). That is a gap of 280 robots per 10,000 workers, or roughly 2.7× China's level. Both figures come from IFR World Robotics via Our World in Data.
Direction of travel matters as much as the gap. China moved from 142 (2023) to 166 (2024), a +16.9% change, while Japan went from 419 to 446, a +6.4% change. China is therefore closing ground or extending its lead faster of the two. Rising density usually reflects new robot installations outpacing manufacturing employment, rather than a shrinking workforce.
On high-performance computing, China has 31 systems on the current TOP500 list against Japan's 44. Autonomous-vehicle figures shown above are modeled estimates and are excluded from the Automation Score.
