Japanese semiconductor equipment makers accelerate AI transformation under export controls: industrial restructuring behind 10% decline in sales to China

Japan's semiconductor equipment industry is redefining its global role. Export controls on 23 types of semiconductor manufacturing equipment, implemented in July 2023, caused the Chinese sales of Japanese companies like Tokyo Electron (TEL) to drop 10% quarter-on-quarter in the third quarter of fiscal 2026, with China's share of TEL's total sales falling from a peak of 41-42% to 31.8%. However, this contraction did not trigger an industry recession—on the contrary, AI-driven demand is becoming a new growth pole.

The Digital Landscape Under Export Controls

Tokyo Electron's financial results reveal the direct impact: China sales plummeted from 279.4 billion yen to 175.5 billion yen. Peers such as SCREEN Holdings, Advantest, and Nikon are under similar pressure. Historically, China contributed 24-30% of revenue for TEL and SCREEN, but that figure is now being re-anchored. TEL expects China's share to stabilize around 30% in the second half of fiscal 2026—still a significant portion, but no longer dominant.

AI as a Hedging Tool

Tokyo Electron has identified AI-related demand as a strategic focus, forecasting that AI will contribute up to 40% of total revenue by fiscal 2026. Despite the decline in China revenue, the company has raised its sales forecast, indicating management's confidence that the AI uptrend is sufficient to offset geopolitical headwinds. This shift is not a stopgap: with restrictions on advanced process equipment exports to China, the expansion of global AI chip manufacturers (such as TSMC, Samsung, Intel) has opened new markets for Japanese equipment makers.

Reshaping the Competitiveness of Japan's Semiconductor Industry

This transformation reveals the deep resilience of Japan's semiconductor equipment industry. While coordinated controls with the U.S. and the Netherlands have compressed the revenue structure in the short term, they have also forced Japanese companies to upgrade from a "cost-performance orientation" to a "technology leadership orientation." Tokyo Electron's technological accumulation in key areas such as deposition and etching gives it an advantage in advanced equipment required for AI chip manufacturing. At the same time, the push for domestic equipment substitution in China is pushing Japanese manufacturers to focus on higher value-added nodes.

Chain Reactions in the Global Supply Chain

China's response will intensify this trend: driven by the need for self-sufficiency, Chinese chipmakers are accelerating the procurement of unrestricted mature process equipment, but this could lead to a global overcapacity in mature processes, thereby suppressing overall equipment orders. For Japanese equipment makers, whether AI-driven demand can fully fill the gap left by China remains to be seen. However, in the long run, Japan's comprehensive advantages in semiconductor materials, equipment, and precision manufacturing will make it a key player in the AI era.

ConclusionJapanese semiconductor equipment makers' "China dependency" is being cured by both geopolitics and the AI wave. This transformation is not only a financial rebalancing but also a repositioning of industrial competitiveness. Going forward, investors should closely monitor two indicators: changes in quarterly revenue share from China, and the backlog of AI-related orders. Japan's equipment industry is proving that even after losing its largest single market, its technological moat can still open up new growth paths.
