[News] Japan Chipmakers, Led by Sony and Mitsubishi, Plan to Invest JPY 5 Trillion in Semiconductors

To capitalize on the expanding opportunities in artificial intelligence (AI), electric vehicles (EV), and the carbon reduction market, eight Japanese companies, including Sony and Mitsubishi Electric, plan to invest JPY 5 trillion (around USD 30 billion) in semiconductors. According to a report by Nikkei on July 8, this investment is expected to increase the production of image sensors, power semiconductors, logic semiconductors, and other products.

Reportedly, eight Japanese companies, including Sony, are planning to invest JPY 5 trillion in semiconductors by 2029, driven by the optimistic outlook for the AI and carbon reduction markets. The report compiled by Nikkei surveys the equipment investment plans of eight major Japanese semiconductor manufacturers for the period from 2021 to 2029: Sony, Mitsubishi Electric, Rohm, Toshiba, Kioxia, Renesas, Rapidus, and Fuji Electric.

The report indicates that Sony will invest roughly JPY 1.6 trillion from 2021 to 2026 to increase the production of CMOS image sensors and other products, with plans to build a new factory in Kumamoto Prefecture. Additionally, Japanese manufacturers are expanding the production of power semiconductors in response to the growing AI data center and EV markets.

Toshiba and Rohm plan to invest a combined total of around 380 billion yen to increase production of silicon (Si) and silicon carbide (SiC) power semiconductors. Mitsubishi Electric aims to increase its SiC power semiconductor capacity to five times the 2022 level by 2026 and will invest about 100 billion yen to build a new factory in Kumamoto Prefecture. Mitsubishi Electric President Kei Urushima stated that they aim to establish a system capable of competing with its rival Infineon, which is the global leader in the SiC power products.

Reportedly, Japanese semiconductor companies held a 50% global market share in 1988. However, after the 1990s, they lost the competition to Taiwanese and South Korean manufacturers, leading to their withdrawal from advanced process research and development in the early 2000s. By 2017, Japan’s market share had fallen below 10%.

In recent years, the Japanese government has been actively revitalizing the semiconductor industry. In the field of advanced logic semiconductors necessary for AI, the Japanese government has decided to provide up to 920 billion yen in support to Rapidus. Rapidus plans to begin trial production of 2-nanometer chips in April 2025 and commence mass production in 2027.
