The Japanese semiconductor sector is seeing significant investment and capacity expansion driven by demand for AI and advanced manufacturing. 

Kyocera announced plans to expand production of ceramic parts and semiconductor packaging, including the opening of a new plant in Nagasaki Prefecture in September 2026. The company also committed a seven-year, ¥1 trillion investment to triple the output of multilayer ceramic capacitors (MLCCs) for AI servers by March 2031.

In a separate development, Sony Group and TSMC are finalizing a joint venture to invest approximately 1 trillion yen ($6.32 billion) in next-generation image sensor manufacturing. Located in Kumamoto Prefecture, the venture aims to combine Sony’s design expertise with TSMC’s manufacturing capabilities to target high-performance applications such as smartphones, robotics, and autonomous vehicles. The companies are reportedly seeking subsidies from Japan’s Ministry of Economy, Trade and Industry to support the project.
