Japanese real estate developer Mitsui Fudosan is set to establish a physical AI development center in Kumamoto Prefecture, adjacent to Taiwan Semiconductor Manufacturing Co.'s (TSMC) production base. The project, named the Kumamoto Science Park Innovation Creation Area, aims to foster collaboration between Japanese and Taiwanese companies to develop next-generation semiconductor technologies for applications in robotics, industrial equipment, and automobiles.
Mitsui Fudosan has entered into a basic agreement with Koshi City and Kumamoto Prefecture to develop approximately 76 acres (31 hectares) of land. This initiative is part of Kumamoto Prefecture's broader 'distributed science park' concept, with Mitsui Fudosan's area serving as a core hub for innovation.
Construction is slated to commence in May 2026, with facilities expected to be completed in stages from 2027, and the entire project anticipated to be finished by 2030. The development will focus on creating an integrated ecosystem that spans research and development to mass production, with an eye toward advanced 3-nanometer semiconductor processes.
The science park will provide essential assets for the semiconductor industry, including R&D facilities, incubation centers, offices, and shared clean rooms. It also aims to build a community by bringing together diverse players such as design, manufacturing, and user companies, as well as academic institutions. The project is designed to enhance industrial competitiveness and contribute to regional revitalization, aligning with the 'New Silicon Island Kyushu' initiative.
