JFE Holdings, Inc. (JFEEF5411.T) and Mitsubishi Corp. (8058.T, MSBHF) have advanced their collaborative efforts to establish a significant power and data center project in Japan, announcing the signing of a second Memorandum of Understanding (MOU). This agreement, disclosed on April 06, 2026, marks a crucial progression from an initial feasibility study signed in March 2025, solidifying plans to form a joint venture. The project, located in the Ohgishima area of the Keihin District, aims to address burgeoning data infrastructure demand while ensuring a stable, sustainable energy supply.
Project Advancement and Strategic Location
The second MOU confirms positive findings from the initial feasibility study, validating the construction of a data center. The companies, with MC Digital Realty, identified approximately five hectares for development, leveraging JFE’s existing plant for power. This integrated approach combines a high-capacity data center with a dedicated, reliable power source. The Ohgishima site in the Keihin District, about 20 kilometers from central Tokyo, positions the facility within a key industrial and economic hub, ensuring optimal connectivity and operational efficiency.
Integrated Power and Capacity Targets
Central to this undertaking is the synergy between data processing and power generation. The project will be supported by a substantial 190 MW power plant, providing the necessary energy backbone. This self-contained power supply model is critical for stability and resilience. The immediate operational target is to launch an initial 60 MW data center in fiscal year 2031, envisioned as a foundation for future expansion. Partners plan to increase capacity over time, adapting to the digital economy’s evolving demands.
Future-Proofing with Green Energy Initiatives
Beyond immediate operational goals, JFE Holdings and Mitsubishi Corp. are committed to future-proofing the project through sustainable energy solutions. The second MOU outlines plans to study increasing overall power generation capacity and integrating greener energy sources. A significant component of this long-term vision includes exploring a planned hydrogen hub. This initiative reflects a broader commitment to reducing the environmental footprint and aligning with Japan’s national goals for decarbonization and energy independence, aiming to set a new standard for sustainable data center development.
Meeting Japan’s Digital and Industrial Needs
The overarching objective of this joint venture is multifaceted: to meet rising demand for data centers across Japan, ensure a robust and sustainable power supply, and actively support the nation’s industrial growth. As Japan continues its digital transformation, reliable and scalable data infrastructure becomes increasingly vital. This project is positioned to be a cornerstone of that infrastructure, providing the computational backbone necessary for innovation and economic expansion. The strategic partnership brings together complementary strengths essential for such a complex and critical development.
Following the announcement, JFE Holdings, Inc. (JFEEF5411.T) traded 0.89% lesser at JPY 1,834.50 on the Tokyo Stock Exchange. Mitsubishi Corp. (8058.T, MSBHF) shares were down 1.10% at JPY 5,415 on the same exchange. Despite these minor fluctuations, the formalization of the second MOU signifies a strong commitment from both entities to a project deemed essential for Japan’s future digital economy and sustainable industrial development.
