- Japan allocates major subsidy to strengthen domestic semiconductor supply for autonomous and AI technologies.
- Sony’s new Kumamoto facility will begin large-scale image sensor production by 2029.
In a strategic move to reinforce its semiconductor ecosystem, Japan has announced financial support for advanced image sensor manufacturing aimed at meeting future mobility and artificial intelligence demands. The initiative focuses on strengthening domestic capabilities in critical components required for autonomous driving systems and physical AI applications. With demand expected to rise significantly over the next decade, the government is positioning itself to secure technological independence and global competitiveness through targeted industrial policies.
During a cabinet briefing held on April 17, Minister of Economy, Trade and Industry Ryosei Akazawa confirmed that subsidies of up to JPY 60 billion will be granted to Sony Semiconductor Manufacturing Corporation. The support is tied to the company’s proposal to expand its image sensor production capabilities. These sensors play a central role in enabling vehicle perception systems, which are critical for autonomous driving functionalities and AI-driven decision-making in modern vehicles.
The approved project falls under the “specified important materials” category defined by the Economic Security Promotion Act. This marks the first instance where the Economic Security Fund has been utilized to support mass production of image sensors. The policy framework is designed to safeguard supply chains for essential technologies, ensuring stable availability of components that are vital for both industrial applications and national security considerations.
Production will be carried out at a newly constructed manufacturing facility located in Koshi City, Kumamoto Prefecture. The plant is expected to begin operations in May 2029, with a production capacity of approximately 10,000 wafers per month based on 300 mm equivalents. The total investment for this initiative stands at JPY 180 billion, reflecting the scale and long-term commitment associated with semiconductor manufacturing expansion in the region.

Alongside this investment, the government has also outlined a broader public-private roadmap targeting leadership in autonomous driving technologies. The plan aims to achieve approximately 25% global market share in autonomous vehicle sales during the 2030s. This vision aligns with the increasing integration of advanced sensors, AI algorithms, and real-time data processing systems in next-generation mobility solutions.
The emphasis on image sensor production highlights the growing importance of perception technologies in automotive innovation. These components are essential for enabling vehicles to detect surroundings, interpret complex environments, and ensure safety in autonomous operations. By supporting domestic manufacturing, Japan is not only addressing supply chain risks but also fostering innovation across the automotive and electronics sectors.
The initiative reflects a broader trend where governments are actively investing in semiconductor infrastructure to secure technological leadership. As autonomous driving and AI applications continue to evolve, the demand for high-performance sensors is expected to accelerate, making such investments critical for long-term industrial competitiveness.
