Japan Subsidizes Sony Image Sensor Expansion to Bolster Its AI-Era Semiconductor Position
Image sensors are critical components in smartphones, vehicle-mounted cameras and robots that recognize their surroundings. They also serve as the “eyes” connecting physical AI to the real world. Japan has incorporated the technology into its economic security and semiconductor supply-chain policies, supporting Sony's expansion in Kumamoto to preserve the country's influence in sensing technology and the underlying hardware for AI.
Japan's Ministry of Economy, Trade and Industry approved Sony Semiconductor Manufacturing's expansion plan on April 17, 2026. The project entails total investment of about 180 billion yen and is eligible for subsidies of up to 60 billion yen. The new plant in Koshi, Kumamoto Prefecture, is scheduled to begin shipments in May 2029 and will have monthly capacity of 10,000 300-millimeter wafers. Sony separately signed a memorandum of understanding with TSMC on May 8 to study the creation of a Sony-controlled joint venture.

The history behind this eventTSMC, Sony Plan ¥1 Trillion Kumamoto Chip Venture for Physical AI
Physical AI systems rely on sensors to interpret real-world conditions and chips to turn that data into decisions for vehicles and robots. A partnership would combine Sony Group’s strength in image-sensing technology with TSMC’s advanced semiconductor manufacturing capabilities, while expanding Japan’s domestic chip supply chain. The project would also position both companies to capture rising demand from autonomous driving and robotics applications.
Sony Group and TSMC plan to invest about ¥1 trillion in a joint venture and production facility in Kumamoto Prefecture, Nikkei reported. The partners aim to begin commercial production of next-generation image-sensor chips as early as 2029. The planned output will target automotive and robotics uses, making the Kumamoto operation a key manufacturing base for their push into Physical AI hardware.
