TSMC’s wafer fab under construction in Kumamoto aligns with the purpose of the Economic Security Promotion Act (ESPA) legislated by the Japanese government in 2022, which highlights Japan’s self-sufficiency in the supply of semiconductors and other specific critical technologies and materials. It appears that the foundry’s Kumamoto Fab 2 investment project is under negotiation, but there are concerns whether the infrastructure there is sufficient to support this project, especially land and water supply.
