SoftBank — Sakai AI Data Center

SoftBank is building a 150 MW AI data center at the former Sharp factory site in Sakai, Osaka, with completion targeted for late 2026. The facility is purpose-built to host NVIDIA Blackwell (DGX B200) systems, serving as a primary “AI Factory” for SoftBank’s sovereign AI initiatives in Japan. The data center will provide high-performance compute capacity for Japanese businesses and researchers to develop localized large language models (LLMs). The project emphasizes high power density and advanced cooling to support the next generation of AI accelerators.
