As of April 6, 2026, JFE Holdings and Mitsubishi Corporation announced a second memorandum of understanding (MOU) toward the joint development of a power business and data center project in the Ohgishima, Keihin District, Kanagawa Prefecture. [1] Under this MOU, the companies will advance the business plan with the aim of entering into a joint venture agreement. The initial MOU, signed in March 2025, aimed to explore the feasibility of this, after which the companies conducted assessments of an integrated power and data center project. By leveraging the advantages of the Ohgishima Area, they were able to find a large-scale site located 20km from central Tokyo with a stable power supply from JFE’s 190 MW captive power plant. The site can support at least 2 data centers, and the companies are targeting the commencement of operations for an initial 60 MW data center in 2031. The feasibility of constructing and operating the data center on 5 hectares of land was confirmed, after which the companies decided to proceed to the joint venture's concretization phase. JFE and Mitsubishi will study the potential supply of green power by leveraging Ohgishima’s planned hydrogen hub to support the future demand for power from continued land use conversion and data center expansion.
