Mitsui Fudosan Signs Basic Agreement with Kumamoto Prefecture and Koshi City: Launching 'Kumamoto Science Park' to Foster a Semiconductor Community

Mitsui Fudosan Co., Ltd. has signed a basic agreement with Kumamoto Prefecture and Koshi City to promote the 'Kumamoto Science Park Innovation Creation Area' project. This project serves as the core of Kumamoto's 'Distributed Science Park' strategy, developing approximately 31 hectares in Koshi City to attract semiconductor-related companies and academic institutions. Construction is set to begin in May 2026, with partial facility completion from 2027 and total completion by 2030. As an 'industrial developer,' Mitsui Fudosan aims to enhance Japan's industrial competitiveness by providing physical assets (factories, R&D centers, incubation spaces, and clean rooms) integrated with community building (networking between industry, academia, and government). Targeting the 3nm semiconductor market, the park seeks to build a robust ecosystem covering everything from research to volume manufacturing, contributing to the 'New Silicon Island Kyushu' vision. The location is strategically placed near global players like JASM (Japan Advanced Semiconductor Manufacturing), Tokyo Electron Kyushu (TKL), and Sony Semiconductor Manufacturing (SCK), benefiting from excellent infrastructure including the upcoming Kumamoto Airport access railway.
